release: v0.1.9

fix(runtime): keep tool-use/tool-result pairs paired in Trident compaction (#3367 )
Trident stage 1 dropped the assistant message that carried a file tool use while keeping the tool result that answered it, so the compacted session ended up with orphaned `tool_result` blocks. Providers reject such requests with HTTP 400 ("tool_result blocks must be a response to a preceding tool_use"), which breaks the auto-compact retry path that runs Trident before resending a request. Stage 1 also counted a tool result as an independent file operation, which pushed `last_write` past the write the result belonged to and made the newest write look obsolete. Only tool uses count as file operations now, and a tool result is dropped together with the tool use that produced it.

Running `claw system-prompt --output-format json` returns `{"kind":"system-prompt","message":"<full prose>","sections":["You are an interactive agent...", "# System\n...", "# Doing tasks\n...", "# Executing actions with care\n...", "__SYSTEM_PROMPT_DYNAMIC_BOUNDARY__", "# Environment context\n...", "# Project context\n...", "# Claude instructions\n...", "# Runtime config\n..."]}`. The `sections` array has 9 elements; element index 4 is the raw string `"__SYSTEM_PROMPT_DYNAMIC_BOUNDARY__"`. This internal sentinel marks the boundary between the static and dynamic sections of the compiled system prompt, used during assembly to split the prompt at injection time. It appears in the public JSON output verbatim as a first-class section, indistinguishable from real sections by type alone. Automation that iterates `sections[]` must special-case this sentinel or it will process an internal implementation string as if it were a real system prompt section. **Required fix shape:** (a) strip `"__SYSTEM_PROMPT_DYNAMIC_BOUNDARY__"` and any similar internal delimiters from the `sections` array before serializing to JSON; (b) if the static/dynamic boundary is semantically meaningful for callers, expose it as a structured metadata field such as `boundary_index:4` or as a `section_type:"static"\|"dynamic"` field on each section entry, not as a raw sentinel string in the array; (c) rename the `sections` type from `string[]` to `[{id, type, content}]` to enable this without breaking the boundary signal; (d) add regression coverage proving the `system-prompt --output-format json` output's `sections` array contains no elements whose value equals `"__SYSTEM_PROMPT_DYNAMIC_BOUNDARY__"` or matches `/__[A-Z_]+__/`. **Why this matters:** internal sentinel strings in public JSON are a contract liability — they couple the wire format to internal implementation details. Any refactor that renames or removes the sentinel breaks callers that don't special-case it, and automation that doesn't know to filter it will miscount, misparse, or misrender the system prompt.

+## OVERVIEW
+Claw Code: public Rust implementation of the `claw` CLI agent harness (Claude-Code-style). Canonical code lives in `rust/`; the repo is an agent-managed exhibit (harnesses plan/execute/verify per README), not a hand-operated product. `src/` is a companion Python porting/parity workspace, not production code.

+
+## CONVENTIONS
+- `unsafe_code = "forbid"` workspace-wide; every crate opts in via `[lints] workspace = true`; clippy all=warn, pedantic=allow
+- Edition 2021, resolver 2, publish=false; no rust-toolchain pin (CI floats stable); no rustfmt.toml/clippy.toml — stock defaults
+- Giant flat files by design (main.rs 19.8k, tools/lib.rs 10.9k, commands/lib.rs 7.2k): organization is positional — types → spec table → dispatch → handlers → tests at EOF
+- Dual output paths everywhere: `render_x` + `render_x_json`; JSON errors to **stdout**, text errors to **stderr**
+- Tests: inline `#[cfg(test)] mod tests` primary; integration tests spawn `CARGO_BIN_EXE_claw` subprocess against mock-anthropic-service; tempfile everywhere; env-mutating tests serialize via env_lock/test_env_lock
+- Comments carry issue numbers (#824, #146); gate tests named by roadmap gate (g004_conformance.rs)
+- Python side: stdlib only, `python -m unittest`; src/ mixes camelCase (QueryEngine.py) and snake_case filenames
+
+## ANTI-PATTERNS (THIS PROJECT)
+- NEVER `cargo install claw-code` — crates.io stub is deprecated and installs `claw-code-deprecated.exe`; build from source
+- Forbidden doc strings (CI-enforced by .github/scripts/check_doc_source_of_truth.py): old org links `github.com/Yeachan-Heo/claw-code`, `github.com/code-yeongyu/claw-code`, `discord.gg/6ztZB9jvWq`, `assets/clawd-hero.jpeg`
+- Deprecated config keys: `permissionMode` → `permissions.defaultMode`; `enabledPlugins` → `plugins.enabled`; env `RUSTY_CLAUDE_PERMISSION_MODE` is dead
+- Direct push to main is policy-blocked (`main_push_forbidden` approval scope)
+- Automation lanes must not merge/close remote PRs/issues (docs/anti-slop-triage.md)
+- `claw init` must not scaffold `dontAsk` permission mode (regression-pinned in output_format_contract.rs)
+- File-level `#![allow(dead_code)]` blocks (main.rs, session_control.rs) are tolerated legacy — do not extend the pattern
+
+## UNIQUE STYLES
+- Dogfood build: scripts/dogfood-build.sh injects GIT_SHA; `claw version` provenance must equal HEAD
+- Mock parity: rust/mock_parity_scenarios.json drives CLI subprocess vs MockAnthropicService
+- Dogfooding uses `CLAW_CONFIG_HOME=$(mktemp -d)` for config isolation
+- Env contracts: GIT_SHA (build), CLAW_CONFIG_HOME (config dir), OLLAMA_HOST (provider override), `*_API_KEY`/`*_BASE_URL` per provider
+
+## COMMANDS
+```bash
+scripts/fmt.sh --check                 # fmt check (apply: scripts/fmt.sh)
+cd rust && cargo clippy --workspace --all-targets -- -D warnings
+cd rust && cargo test --workspace

+python .github/scripts/check_doc_source_of_truth.py && scripts/roadmap-check-ids.sh   # docs/roadmap CI
+```
+
+## NOTES
+- `claw` binary comes from crate `rusty-claude-cli` (package/bin name mismatch)
+- rust-ci.yml triggers only on rust/**, docs/**, listed meta file changes (path filters)
+- CI clippy job runs without `-D warnings` — weaker than the documented gate; known pre-existing failures recorded in docs/g002/g003 maps
+- `claw acp` is a status stub, not a real ACP server
+- rust/ has committed harness dotdirs (.clawd-agents/, .omc/, .sandbox-home/) — intentional

+## Local pre-push build gate
+
+Install the repository-local hook to catch stale compile errors before pushing:
+
+```bash
+git config core.hooksPath .github/hooks
+```
+
+This sets the repo's Git hook directory to `.github/hooks`; if you already use a
+custom `core.hooksPath`, copy or chain `.github/hooks/pre-push` instead. The hook
+runs the ROADMAP id guard, then runs
+`cargo build --manifest-path rust/Cargo.toml --workspace --locked` from the
+repository root. If you must bypass the cargo build for a docs-only push, set
+`SKIP_CLAW_PRE_PUSH_BUILD=1`; the hook still runs the ROADMAP guard and prints
+when the cargo-build escape hatch is used.
+
+## ROADMAP id allocation
+
+Before appending a new numeric ROADMAP entry, pull/rebase onto the latest
+`main`, allocate the id from the file you are about to edit, and run the duplicate
+id guard before pushing:
+
+```bash
+git pull --rebase
+NEXT=$(scripts/roadmap-next-id.sh)
+# append "${NEXT}. **...**" to ROADMAP.md
+scripts/roadmap-check-ids.sh
+```
+
+The duplicate guard currently checks helper-era ids (`>=723`) by default so it
+catches new optimistic-append collisions without failing on legacy numbered lists
+already present in the historical roadmap. Use `scripts/roadmap-check-ids.sh
+--min-id 1` for a strict whole-file audit after those legacy collisions are
+cleaned up.

+> **Claw Code is not the serious production project here.**
+> This repository is closer to a museum exhibit than a product pitch, a crustacean-run artifact kept alive by clawed gajaes, swept and labeled by agents, and automatically maintained according to the harnesses above.
+>
+> As already described in the project philosophy, this is not meant to be hand-operated like a normal product repo. It is an **agent-managed exhibit**: the harnesses plan, execute, verify, label, and preserve the artifact while the crabs keep the tank running.
+>
+> If you want to actually run work, start with **[LazyCodex](https://github.com/code-yeongyu/lazycodex)** or **[Gajae-Code](https://github.com/Yeachan-Heo/gajae-code)**. If you want to inspect the strange little fossil of the Claw Code moment, continue below.

+> **Claw Code 在这里并不是一个严肃的生产级项目。**
+> 这个代码库更像是一个博物馆的展品，而不是一个产品推介。它是一个由螃蟹（crab）驱动的工件，由带爪子的 gajae（小龙虾）维持生命，由智能体清扫和贴标签，并根据上述的工具（harnesses）自动维护。
+>
+> 正如项目理念中所描述的，这并不旨在像普通产品代码库那样由人工操作。它是一个**由智能体管理的展品 (agent-managed exhibit)**：当螃蟹保持水箱运转时，工具会规划、执行、验证、标记并保存该工件。

+## 快速入门
+
+> [!NOTE]
+> [!WARNING]
+> **`cargo install claw-code` 会安装错误的东西。** crates.io 上的 `claw-code` crate 是一个已废弃的存根（stub），它会放置 `claw-code-deprecated.exe` — 而不是 `claw`。运行它只会打印 `"claw-code has been renamed to agent-code"`。**请勿使用 `cargo install claw-code`。** 请从源码构建（本代码库）或安装上游二进制文件：
+> ```bash
+> cargo install agent-code   # 上游二进制文件 — 安装为 'agent.exe' (Windows) / 'agent' (Unix)，而不是 'agent-code'
+> ```
+> 本代码库 (`ultraworkers/claw-code`) **仅支持从源码构建** — 请遵循以下步骤。
+
+```bash
+# 1. 克隆并构建
+git clone https://github.com/ultraworkers/claw-code
+cd claw-code/rust
+cargo build --workspace
+
+# 2. 设置您的 API 密钥（Anthropic API 密钥 — 不是 Claude 订阅）
+export ANTHROPIC_API_KEY="sk-ant-..."
+
+# 3. 验证所有配置是否正确
+./target/debug/claw doctor
+
+# 4. 运行提示词
+./target/debug/claw prompt "say hello"
+
+# 5. 启动交互式会话
+./target/debug/claw
+```
+
+> [!NOTE]
+> **Windows (PowerShell)：** 二进制文件是 `claw.exe`，而不是 `claw`。使用 `.\target\debug\claw.exe` 或运行 `cargo run -- prompt "say hello"` 以跳过路径查找。
+
+### Windows 设置
+
+**PowerShell 是一种支持的 Windows 路径。** 您可以使用任何适合您的终端 shell。Windows 上常见的入门问题是：
+
+1. **首先安装 Rust** — 从 <https://rustup.rs/> 下载并运行安装程序。完成后关闭并重新打开终端。
+2. **验证 Rust 是否在 PATH 中：**
+   ```powershell
+   cargo --version
+   ```
+   如果失败，请重新打开终端或运行 Rust 安装程序输出的 PATH 设置步骤，然后重试。
+3. **克隆并构建**（在 PowerShell、Git Bash 或 WSL 中均可）：
+   ```powershell
+   git clone https://github.com/ultraworkers/claw-code
+   cd claw-code/rust
+   cargo build --workspace
+   ```
+4. **运行**（PowerShell — 注意 `.exe` 和反斜杠）：
+   ```powershell
+   $env:ANTHROPIC_API_KEY = "sk-ant-..."
+   .\target\debug\claw.exe prompt "say hello"
+   ```
+
+有关发布版的 ZIP、PATH 设置、提供商切换以及通知的冒烟测试，请参阅 [`docs/windows-install-release.md`](./docs/windows-install-release.md)。
+
+**Git Bash / WSL** 是可选的替代方案，而非必须。如果您更喜欢 bash 风格的路径（例如 `/c/Users/you/...` 而不是 `C:\Users\you\...`），Git Bash（随 Git for Windows 一起提供）效果很好。在 Git Bash 中，`MINGW64` 提示符是预期的正常现象 — 并不代表安装已损坏。
+
+## 构建后操作：定位二进制文件并验证
+
+在 `claw-code/rust/` 中运行 `cargo build --workspace` 后，`claw` 二进制文件已构建，但**不会**自动安装到您的系统中。以下是定位文件和验证构建是否成功的方法。
+
+### 二进制文件位置
+
+`cargo build --workspace` 后，在 `claw-code/rust/` 目录中：
+
+**Debug 构建（默认，编译较快）：**
+- **macOS/Linux：** `rust/target/debug/claw`
+- **Windows：** `rust/target/debug/claw.exe`
+
+**Release 构建（已优化，编译较慢）：**
+- **macOS/Linux：** `rust/target/release/claw`
+- **Windows：** `rust/target/release/claw.exe`
+
+如果您运行 `cargo build` 时没有添加 `--release`，则二进制文件位于 `debug/` 文件夹中。
+
+### 验证构建是否成功
+
+直接使用其路径测试二进制文件：
+
+```bash
+# macOS/Linux (debug 构建)
+./rust/target/debug/claw --help
+./rust/target/debug/claw doctor
+
+# Windows PowerShell (debug 构建)
+.\rust\target\debug\claw.exe --help
+.\rust\target\debug\claw.exe doctor
+```
+
+无需实时凭据的 PowerShell 冒烟测试命令：
+
+```powershell
+$env:CLAW_CONFIG_HOME = Join-Path $env:TEMP "claw config home"
+New-Item -ItemType Directory -Force -Path $env:CLAW_CONFIG_HOME | Out-Null
+Remove-Item Env:\ANTHROPIC_API_KEY, Env:\ANTHROPIC_AUTH_TOKEN, Env:\OPENAI_API_KEY -ErrorAction SilentlyContinue
+.\rust\target\debug\claw.exe help
+.\rust\target\debug\claw.exe status
+.\rust\target\debug\claw.exe config env
+.\rust\target\debug\claw.exe doctor
+```
+
+如果这些命令成功执行，说明构建正常工作。`claw doctor` 是您的首个健康检查工具 — 它会验证您的 API 密钥、模型访问权限和工具配置。
+
+### 可选：添加到 PATH
+
+如果您希望在任何目录下都不用输入完整路径即可运行 `claw`，请选择以下方法之一：
+
+**选项 1：符号链接 (macOS/Linux)**
+```bash
+ln -s $(pwd)/rust/target/debug/claw /usr/local/bin/claw
+```
+然后重新加载 shell 并测试：
+```bash
+claw --help
+```
+
+**选项 2：使用 `cargo install` (所有平台)**
+
+构建并安装到 Cargo 的默认位置（`~/.cargo/bin/`，通常已在 PATH 中）：
+```bash
+# 在 claw-code/rust/ 目录下
+cargo install --path . --force
+
+# 然后在任何地方都可以运行
+claw --help
+```
+
+**选项 3：更新 shell 配置文件 (bash/zsh)**
+
+将此行添加到 `~/.bashrc` 或 `~/.zshrc`：
+```bash
+export PATH="$(pwd)/rust/target/debug:$PATH"
+```
+
+重新加载 shell：
+```bash
+source ~/.bashrc  # 或 source ~/.zshrc
+claw --help
+```
+
+### 故障排除
+
+- **"command not found: claw"** — 二进制文件在 `rust/target/debug/claw`，但未在您的 PATH 中。请使用完整路径 `./rust/target/debug/claw` 或按照上述方法进行软链接/安装。
+- **"permission denied"** — 在 macOS/Linux 上，如果缺少可执行权限（罕见情况），您可能需要运行 `chmod +x rust/target/debug/claw`。
+- **Debug vs. release** — 如果构建运行缓慢，说明您处于 debug 模式（默认）。在 `cargo build` 中添加 `--release` 以获得更快的运行时速度，但这会使构建本身花费 5-10 分钟。
+
+> [!NOTE]
+> **认证：** claw 需要一个 **API 密钥** (`ANTHROPIC_API_KEY`, `OPENAI_API_KEY` 等) — 暂不支持 Claude 订阅登录作为认证途径。
+
+在验证二进制文件可运行后，执行工作区测试套件：
+
+```bash
+cd rust
+cargo test --workspace
+```

+# Issue #3283 Triage Summary
+
+**Issue:** docs: document OmniRoute OpenAI-compatible setup  
+**Opened by:** @diegosouzapw  
+**Status:** BLOCKED (waiting for clarification)  
+**Date:** 2026-10-13
+
+## Findings
+
+### Investigation
+1. Searched codebase for "OmniRoute" — **no matches found**
+2. Searched documentation (docs/local-openai-compatible-providers.md, MODEL_COMPATIBILITY.md) — **no mentions**
+3. Searched git history (commits, branches, PRs) — **no references**
+4. Checked GitHub API (rate limited, but issue title confirmed)
+
+### Current State
+- Issue #3283 is OPEN
+- No labels assigned
+- Title: "docs: document OmniRoute OpenAI-compatible setup"
+- This is a documentation request for setting up an OpenAI-compatible provider
+
+### Existing Documentation
+The repository already has comprehensive documentation for OpenAI-compatible providers:
+- `docs/local-openai-compatible-providers.md` — documents Ollama, llama.cpp, vLLM, and OpenRouter
+- `docs/MODEL_COMPATIBILITY.md` — model-specific provider routing details
+- `rust/crates/api/src/providers/openai_compat.rs` — provider implementation
+
+## Next Steps
+
+**Action taken:** Comment added to issue asking for:
+1. OmniRoute documentation/website link
+2. OpenAI-compatible endpoint example (base URL, API key format)
+3. Model ID examples
+4. Any special configuration or known quirks
+
+**Comment posted to:** https://github.com/ultraworkers/claw-code/issues/3283#issuecomment-6133484114
+
+## Conclusion
+
+**Cannot proceed without user input.** Once the user provides the necessary information about OmniRoute, the fix will involve:
+1. Adding a new section to `docs/local-openai-compatible-providers.md`
+2. Including setup example (environment variables, model names, basic smoke test)
+3. Following the existing format used for Ollama, llama.cpp, vLLM sections
+4. Creating a PR for review

+Model selection precedence is CLI flag, environment, config, then default. The environment model slot accepts `CLAW_MODEL`, `ANTHROPIC_MODEL`, and `ANTHROPIC_DEFAULT_MODEL` in that order; aliases from those variables are resolved and validated before provider startup. `claw --output-format json status` exposes `model_raw`, `model_alias_resolved_to`, and `model_env_var` so automation can see the winning value.

+## Install an external skill
+
+`claw skills install <path>` accepts a local skill directory that contains

+
+For example, install TweetClaw as an X/Twitter automation skill:
+

 5. `<repo>/.claw/settings.local.json`

+The list is also the precedence chain: project-local settings override project settings, project settings override the legacy project `.claw.json`, and project files override user files. `claw --output-format json config` includes each discovered file's `precedence_rank`, `wins_for_keys`, and `shadowed_keys` so automation can see which file controls each effective key without reimplementing the merge order.
+
+## MCP server validation
+
+`claw mcp --output-format json` loads valid `mcpServers` entries even when sibling entries are malformed. The JSON list envelope distinguishes the total configured entries from the valid and invalid subsets:
+
+```json
+{
+  "configured_servers": 1,
+  "total_configured": 2,
+  "valid_count": 1,
+  "invalid_count": 1,
+  "servers": [{ "name": "valid-server", "valid": true }],

+      "reason": ".claw.json: mcpServers.missing-command: missing string field command",
+      "valid": false
+    }
+  ]
+}
+```
+
+`status --output-format json` mirrors this under `mcp_validation`, and `doctor --output-format json` includes an `mcp validation` check so automation can repair every rejected server entry without losing usable MCP servers.
+
+## Hook configuration
+
+`hooks.PreToolUse`, `hooks.PostToolUse`, and `hooks.PostToolUseFailure` accept either legacy command strings or object-style entries with a `matcher` and nested command hooks:
+
+```json
+{
+  "hooks": {
+    "PreToolUse": [
+      "echo legacy hook",
+      {
+        "matcher": "Bash",
+        "hooks": [

+        ]
+      }
+    ]
+  }
+}
+```
+
+Object-style matchers are optional. When present, they match tool names case-insensitively and support `*` wildcards plus comma or pipe separated alternatives. Nested hook `type` may be omitted or set to `"command"`; each nested command runs in configuration order.
+Legacy bare-string hook entries still load for backward compatibility but emit deprecation warnings suggesting migration to object-style entries. Unknown hook event names (e.g. `Stop`, `Notification`) are recorded as invalid without rejecting valid hooks. `status --output-format json` mirrors partial hook validation under `hook_validation` with `valid_count`, `invalid_count`, and `invalid_hooks:[{event, index, hook_index, kind, error_field, reason, valid:false}]`. `doctor --output-format json` includes a `hook validation` check so automation can repair every rejected hook entry without losing usable hooks.
+
+## Project instruction rules
+
+In addition to root instruction files such as `CLAUDE.md`, `CLAW.md`, `AGENTS.md`, `.claw/CLAUDE.md`, `.claude/CLAUDE.md`, and `.claw/instructions.md`, `claw` loads sorted Markdown/text rule files from:
+
+- `<repo>/.claw/rules/` (`.md`, `.txt`, `.mdc`) for shared project rules.
+- `<repo>/.claw/rules.local/` for personal local rules; this path is gitignored.
+
+Root instruction-file priority is `CLAUDE.md`, then `CLAW.md`, then `AGENTS.md` for each discovered directory. Discovery is bounded to the current git root when one exists, otherwise to the current directory only, so stale parent files outside the project do not silently bleed into the prompt. All loaded files contribute to the system prompt and to `status --output-format json` as `workspace.memory_files:[{path, source, origin, scope_path, outside_project, chars, contributes}]`; `claw doctor --output-format json` includes a `memory` check so automation can detect loaded and unexpected unloaded memory-file candidates without parsing prompt text.
+
+By default, `claw` also imports detected rules from common AI coding tools such as Cursor (`.cursorrules`, `.cursor/rules/`), GitHub Copilot (`.github/copilot-instructions.md`), Windsurf, Plandex, and Crush. Control this with `rulesImport` in any settings file:
+
+```json
+{
+  "rulesImport": "none"
+}
+```
+
+Use `"auto"` (the default) to import every supported framework, `"none"` to load only Claw instruction/rules files, or an array such as `["cursor", "copilot"]` to import selected frameworks.

+# Концепция проекта Claw Code
+
+Документ фиксирует **цели**, **архитектуру** и **принципы** репозитория **Claw Code** — публичной Rust-реализации CLI-агента **`claw`** и сопутствующих инструментов. Источник правды по кодовой базе: workspace в каталоге [`rust/`](rust/README.md); операционные сценарии — [`USAGE.md`](USAGE.md), [`how_to_run.md`](how_to_run.md) (claw-analog), бэклог идеи — [`futute.md`](futute.md).
+
+Отдельная продуктовая линия «из CLI → в личного помощника» (каналы/память/инструменты/проактивность/сессии) описана в [`docs/personal-assistant-roadmap.md`](docs/personal-assistant-roadmap.md).
+
+---
+
+## 1. Назначение продукта
+
+**Claw Code** — это:
+
+1. **Основной CLI `claw`** (`rusty-claude-cli`): полнофункциональный агент с REPL, OAuth, расширенным набором инструментов (включая bash, MCP, плагины и др.), стримингом и интеграцией с провайдерами **Anthropic**, **OpenAI-совместимыми** API и **xAI**.
+2. **`claw-analog`** — облегчённая оболочка на **том же слое API** (`api` crate): узкий, предсказуемый набор инструментов только для работы с файловой системой воркспейса, явные режимы прав, пригодность для **CI**, **скриптов** и **внешних агентов** (NDJSON).
+3. **`claw-rag-service`** — отдельный процесс: **индексация** репозитория (чанки + эмбеддинги в SQLite), **HTTP API** для семантического поиска и минимальный **веб-UI** для ручной проверки индекса.
+
+Общая идея: дать **безопасный**, **аудируемый** и **воспроизводимый** способ вызова LLM над кодом и документацией, с путём эволюции от минимального harness до полного `claw`.
+
+---
+
+## 2. Целевая аудитория и сценарии
+
+| Сегмент | Задача |
+|---------|--------|
+| Разработчик | Ежедневная работа с кодовой базой через полный `claw`: REPL, инструменты, сессии. |
+| Автор автоматизации | Одноразовые промпты, пайплайны с `--output-format json`, встроенные агенты без bash. |
+| Сопровождение / аудит | `claw-analog` в **read-only** + пресет **audit**; явные лимиты и политика. |
+| Порт и parity | Сравнение поведения с эталоном (`PARITY.md`, mock-harness). |
+| RAG над монорепо | Отдельный `ingest` + `serve`; агент подключает контекст через **`retrieve_context`** при заданном `RAG_BASE_URL`. |

+
+**Принцип разделения:** тяжёлая индексация и хранение эмбеддингов **не** зашиваются в `claw-analog`, а живут в **`claw-rag-service`**. Агент только вызывает retrieval по HTTP — проще масштабировать, менять векторное хранилище и секреты эмбеддингов.
+
+---
+
+## 4. Принципы проектирования
+
+1. **Безопасность по умолчанию** — относительные пути, запрет `..`, проверка выхода за canonical workspace; режимы `PermissionMode` согласованы с полным CLI; в неинтерактивном режиме опасные режимы блокируются без явного флага.
+2. **Явные лимиты** — размер чтения, число ходов, glob/grep caps, таймауты RAG; сбои предсказуемы, а не «OOM или вечный цикл».
+3. **Наблюдаемость для агентов** — NDJSON с `schema` и `format_version` на `run_start`, структурированные `tool_result`.
+4. **Модульность** — общий `api` для провайдеров; `claw-analog` не дублирует стек ключей RAG, только HTTP-клиент к сервису.
+5. **Паритет и тесты** — mock Anthropic, сценарии harness, отдельные job’ы CI для критичных crate’ов.
+6. **Документация рядом с кодом** — `how_to_run.md`, `docs/rag-web-ui.md`, `docs/container.md` и т.д.
+
+---
+
+## 5. Компоненты workspace (кратко)
+
+- **`rusty-claude-cli`** — основной бинарь **`claw`**: пользовательский продукт полной мощности.
+- **`api`** — клиенты провайдеров, стриминг, типы запросов/ответов.
+- **`runtime`** — сессии, конфиг, **PermissionPolicy** / **PermissionEnforcer**, промпты, MCP и др.
+- **`tools`** — встроенные инструменты полного CLI.
+- **`claw-analog`** — минимальный цикл: инструменты чтения/поиска/записи (по режиму), стриминг и JSON, TOML-конфиг, сессии, doctor, config validate, **retrieve_context** при наличии `RAG_BASE_URL` / `rag_base_url`.
+- **`claw-rag-service`** — `ingest`, `serve`, маршруты `/`, `/health`, `/v1/stats`, `/v1/query`; SQLite + OpenAI-совместимые эмбеддинги (или mock для тестов).
+- **`mock-anthropic-service`**, **`compat-harness`** и др. — воспроизводимость и миграция.
+
+Подробная раскладка: [`rust/README.md`](rust/README.md).
+
+---
+
+## 6. Claw-analog: роль и границы
+
+**Задача:** дать «агента с инструментами» без разрастания поверхности атаки (нет произвольного shell в базовом сценарии).
+
+**Инструменты (концептуально):** чтение и обход дерева (`read_file`, `list_dir`, `glob_workspace`), литеральный поиск (`grep_workspace` / `grep_search`), опционально `write_file`, опционально **`retrieve_context`** к RAG-сервису.
+
+**Не входит в минимальный дизайн:** MCP, плагины, bash — это зона **полного `claw`**.
+
+---
+
+## 7. RAG-сервис: роль и эволюция
+
+**Сейчас (MVP):** полный переиндекс при `ingest`, векторы в SQLite, поиск — линейный косинус по всем чанкам; подходит для умеренных объёмов кода.
+
+**Направления роста (концепция):** инкрементальная индексация, ANN (sqlite-vec, Qdrant/Chroma в Docker), rate limits на эмбеддинги. Веб-UI на `GET /` — вспомогательный; продвинутый UI и авторизация — по мере необходимости.
+
+Детали: [`docs/rag-web-ui.md`](docs/rag-web-ui.md).
+
+---
+
+## 8. Репозиторий вне основного runtime
+
+- **`src/`**, **`tests/`** (Python и прочее) — вспомогательные/экспериментальные артефакты; **канонический runtime** — **`rust/`**.
+- Документы **PHILOSOPHY.md**, **ROADMAP.md**, **PARITY.md** дополняют концепцию процессом и намерениями сообщества/мейнтейнеров.
+
+---
+
+## 9. Связанные концепции (не ядро Claw Code)
+
+В **`docs/`** могут находиться переносимые заметки для **других** продуктов (например локальный vision для NestJS-приложений) — они **не** определяют обязательное поведение `claw`, но отражают смежный интерес contributors.
+
+---
+
+## 10. Итоговая формулировка
+
+**Claw Code** — это экосистема **Rust** вокруг агента **`claw`**: полный CLI для разработчиков, **`claw-analog`** как управляемый минимальный агент для автоматизации и **отдельный RAG-сервис** для семантического поиска по коду. Проект опирается на **явные права**, **лимиты**, **тестируемость** и **чёткие HTTP-границы** между агентом и тяжёлой индексацией.

 **Behavior:**
- The default OpenAI API treats `openai/` as a routing prefix and sends the bare model name on the wire.
- Custom OpenAI-compatible base URLs preserve slash-containing slugs such as `openai/gpt-4.1-mini` so the gateway receives the exact model ID it expects.

+- Non-local custom OpenAI-compatible base URLs preserve slash-containing slugs such as `openai/gpt-4.1-mini` so gateways like OpenRouter receive the exact model ID they expect. Local slash-containing model IDs can use `local/`, which strips only that escape-hatch prefix and sends the remainder verbatim.

+# Bundled Skills Registry and Chaining
+
+## Overview
+
+The bundled skills registry enables claw-code to include built-in skills with each release, similar to how bundled plugins work. This feature supports skill chaining, allowing skills to invoke and compose with other skills.
+
+## Implementation
+
+### Architecture
+
+**Bundled Skills Root Discovery**: Skills are discovered from the following locations (in order of precedence):
+
+1. `<exe_dir>/../share/claw/skills/bundled` — standard FHS install layout
+2. `<exe_dir>/bundled-skills` — simple relocated layout  
+3. `CARGO_MANIFEST_DIR/bundled` — dev/source-tree fallback
+4. Default fallback if above paths don't exist
+
+The directory structure mirrors the plugin system:
+```
+rust/crates/commands/bundled/
+├── example-skill/
+│   └── SKILL.md
+└── chain-example/
+    └── SKILL.md
+```
+
+### SkillOrigin Enum
+
+A new `Bundled` variant was added to the `SkillOrigin` enum:
+
+```rust
+enum SkillOrigin {
+    SkillsDir,           // User/project skills directories
+    LegacyCommandsDir,   // Legacy /commands directories
+    Bundled,             // Built-in bundled skills [NEW]
+}
+```
+
+### Skill Discovery
+
+The `discover_skill_roots()` function was updated to include bundled skills:
+- Bundled skills are added to the discovery roots with `SkillOrigin::Bundled`
+- They're loaded using the same mechanism as regular skills
+- Bundled skills have origin metadata ("bundled") in JSON output
+
+### Skill Chaining
+
+Skills can invoke other skills through standard mechanisms:
+
+1. **Slash Command Invocation**: A skill can document that it chains to another skill
+   ```
+   /skill chain-example
+   ```
+   
+2. **Tool-based Invocation**: Via the Skill tool or similar mechanisms
+
+Skills marked as "bundled" indicate they're managed by the claw-code release and persist across upgrades.
+
+## Example Bundled Skills
+
+### `example-skill`
+A simple demonstration skill showing the bundled skills feature.
+
+### `chain-example`  
+An example showing how one skill can reference and chain to other skills (e.g., `example-skill`).
+
+## Testing
+
+Three new tests were added:
+
+1. **`discovers_bundled_skills_from_binary_layout`**
+   - Verifies that `discover_skill_roots()` includes bundled skills
+   - Tests directory discovery logic
+
+2. **`bundled_skills_have_correct_origin_metadata`**
+   - Confirms `SkillOrigin::Bundled` generates correct metadata
+   - Tests JSON output format
+
+3. **`bundled_skills_are_included_in_json_output`**
+   - Verifies loaded bundled skills appear in JSON output
+   - Tests end-to-end loading flow
+
+All tests pass with:
+```bash
+cargo test -p commands --lib
+```
+
+## Backward Compatibility
+
+- Existing skill discovery paths unchanged
+- `SkillsDir` and `LegacyCommandsDir` origins fully preserved
+- No changes to skill file format or content
+- Bundled skills are additive; they don't replace user/project skills
+
+## Future Enhancement Points
+
+1. **Bundled Skills Registry Sync**: Auto-sync bundled skills into a system registry (similar to plugins)
+2. **Skill Dependency Resolution**: Automatic dependency discovery and loading
+3. **Skill Versioning**: Track versions of bundled skills
+4. **Skill Auto-Update**: Sync bundled skills on claw-code updates

+# G013 ROADMAP pinpoints #693-#695 verification map
+
+This map records the current-head follow-up that was discovered after resetting
+`main` to `origin/main`: ROADMAP.md contained three new Pinpoint headings not
+covered by the Claw Code 2.0 board.
+
+## Pinpoint #693 — typed phase error instead of silent `unknown`
+
+- Code: `rust/crates/claw-analog/src/lib.rs`
+- Behavior: `format_rag_query_json_for_model` now rejects missing, empty, or
+  literal `"unknown"` phase values with a structured error envelope containing
+  `kind:"unknown_bootstrap_phase"`, `field:"phase"`, and `received_value`.
+- Regression tests: `rag_response_missing_phase_returns_typed_error` and
+  `rag_response_unknown_phase_returns_typed_error`.
+
+## Pinpoint #694 — local pre-push build gate
+
+- Hook: `.github/hooks/pre-push`
+- Install command: `git config core.hooksPath .github/hooks`
+- Gate: `cargo build --manifest-path rust/Cargo.toml --workspace --locked`
+- Escape hatch: `SKIP_CLAW_PRE_PUSH_BUILD=1` prints an explicit skip message.
+- Regression test: `tests/test_pre_push_hook_contract.py` locks the skip
+  hatch and `--locked` build command contract.
+- Purpose: mirror the CI build job locally so stale field/variant references are
+  caught before push.
+
+## Pinpoint #695 — startup/worktree preflight diagnostics
+
+- Code: `rust/crates/runtime/src/worker_boot.rs`
+- Behavior: `startup_preflight_warnings` and
+  `WorkerRegistry::observe_startup_preflight` emit structured warnings before
+  the first model turn when a task mentions a path not tracked on the current
+  branch (`file_absent_on_branch`) or git metadata is not writable
+  (`git_metadata_not_writable`).
+- Regression tests:
+  - `startup_preflight_warns_when_task_file_is_absent_on_branch`
+  - `startup_preflight_records_structured_warning_event`

+# GJC Compatibility Gap Matrix
+
+**Document Status**: Historical Planning Reference (updated 2026-10-13)  
+**Scope**: SDK wire protocol, session lifecycle, tools, skills, settings, hooks, commands, and AGENTS.md rules  
+**Target**: Rust fork-in-spirit of gajae-code (GJC) SDK-compatible and capability-compatible

+
+## 2. SDK WIRE PROTOCOL
+
+### GJC Behavior (gajae-code Reference)
+
+**Source**: `packages/coding-agent/src/sdk/client/client.ts`, `sdk/host/session-runtime.ts`
+
+GJC uses a **WebSocket-based JSON-RPC-like protocol** with:
+- **Transport**: WebSocket over TCP
+- **Frame Format**: JSON object with typed fields
+- **Correlation**: Request/response matched by `frame.id` (UUID)
+- **Operations**: 65+ operation types (Q1-Q32, C01-C06, reverse ops)
+- **Error Handling**: Typed `SdkErrorCode` with `uncertain_after_send` recovery
+- **Reconnect**: Exponential backoff with deadline management
+- **Request Timeout**: 10s default (`DEFAULT_SDK_REQUEST_TIMEOUT_MS`), per-request override
+- **Handshake**: `client.hello` with capabilities advertised; `server.hello` response
+
+**Operations** (sample):
+- **Control**: `turn.create`, `turn.prompt`, `turn.steer`, `turn.abort_and_prompt`
+- **Queries**: `turn.list`, `turn.get_one`, `turn.message_list`, `skill.source`, `artifact.content`
+- **Reverse**: `ask.answer`, `tool.dispatch`, `tool.fetch_capability`
+
+**Event Schema**:
+```json
+{
+  "id": "uuid-string",
+  "operation": "turn.create",
+  "input": { ... },
+  "connectionId": "optional",
+  "settings": { ... }
+}
+```
+
+### claw-code Status
+
+**Current** (as of PR #3330): Implemented. WebSocket-based JSON-RPC transport in `rust/crates/sdk/` with:
+- `transport.rs`: WebSocket client/server, frame send/recv
+- `frame.rs`: Frame struct, JSON serialization
+- `error.rs`: SDK error types with `uncertain_after_send` recovery semantics
+
+Remaining: Operation type definitions (Q1-Q32, C01-C06), reverse operation handlers, session reconciliation.
+
+**Files**: None  
+**Lines**: 0
+
+**Reality**: 
+- claw-code operates as a local CLI only (stdin/stdout/stderr).
+- Sessions are file-based (`.claw/sessions/`).
+- No remote access or external SDK clients.
+- No WebSocket transport.
+- No frame correlation or reconnect logic.
+
+### Gap Assessment
+
+| Component | GJC | claw-code | Gap | Complexity |
+|-----------|-----|-----------|-----|------------|
+| WebSocket Transport | 1500 LOC | — | 100% | High |
+| Frame Correlation | 800 LOC | — | 100% | Medium |
+| Operation Registry | 400 LOC | 0 | 100% | Medium |
+| Error Handling & Recovery | 600 LOC | — | 100% | High |
+| Handshake & Negotiation | 200 LOC | — | 100% | Low |
+| **Total** | **3,500 LOC** | **0** | **3,500 LOC** | — |

+
+---
+
+## 3. SESSION LIFECYCLE
+
+### GJC Behavior (gajae-code Reference)
+
+**Source**: `packages/coding-agent/src/sdk/host/session-runtime.ts`, `sdk/client/`, `sdk/lifecycle/`
+
+GJC sessions have **three entry points**:
+1. **Native SDK** (via WebSocket): typed `SdkClient` with `session.create`, `session.prompt`, etc.
+2. **Browser ACP** (via iframe): same protocol, browser sandbox isolate
+3. **CLI Daemon** (stdio): JSON-RPC over stdio for local CLI access
+
+**Session Operations**:
+- **create**: `turn.create(model, input)` → returns `sessionId`, persistent state written to broker DB
+- **prompt**: `turn.prompt(request, tools, settings)` → streams events: `agent_begin`, `tool_use`, `tool_result`, `agent_end`
+- **steer**: `turn.steer(overrides)` → mid-flight direction change (model, settings, system prompt)
+- **abort**: `turn.abort_and_prompt()` → terminal failure + new prompt in one operation
+- **list**: `turn.list(filters)` → paginated session history
+- **get_one**: `turn.get_one(sessionId, turnId)` → single turn with full details
+
+**State Persistence**:
+- Invocation record (prompt request, outcome, correlation)
+- Message buffer (system, assistant, tool results, agent events)
+- Reconciliation store (uncertain → durable mapping)
+- Terminal scope (last session per correlation key)
+
+**Lifecycle Events**:
+1. `turn_accepted` (immediate, transient)
+2. `agent_begin` (before first model call)
+3. `tool_use` + `tool_result` (interleaved)
+4. `agent_end` (final model output)
+5. `turn_ended` (durable, terminal outcome recorded)
+
+### claw-code Status
+
+**Current**: The SDK now exposes `sdk::session::SessionRouter` with durable `turn.create`, `turn.prompt`, `turn.steer`, `turn.abort_and_prompt`, and paginated `turn.list` handling. It bridges `runtime::Session`/`ConversationRuntime`, streams ordered lifecycle events, persists invocation outcomes for reconciliation, and stores terminal session scope by correlation key. The WebSocket transport remains a client transport; a remotely hosted broker and automatic recovery of an unknown post-crash outcome remain outside this slice.
+
+**Files**:
+- `rust/crates/runtime/src/session.rs` (1,961 LOC)
+- `rust/crates/runtime/src/conversation.rs` (conversation loop and lifecycle event bridge)
+- `rust/crates/runtime/src/session_control.rs` (file ops, migration)
+- `rust/crates/runtime/src/lib.rs` (re-exports `Session`, `SessionStore`, `ConversationRuntime`)
+- `rust/crates/sdk/src/session/` (router, event stream, reconciliation, terminal scope)
+
+**Lines**: ~3,900 LOC (session + conversation)
+
+**Reality**:
+- `Session` holds persisted conversation state and `SessionStore` resolves session IDs in the workspace namespace.
+- `ConversationRuntime` drives the local agent loop and emits lifecycle events to an optional callback.
+- `sdk::session::SessionRouter` dispatches the five turn operations and exposes a per-invocation event stream.
+- Invocation terminal outcomes and correlation-key terminal scopes are durable; startup recovery marks unfinished invocations uncertain for later reconciliation.
+- A remote WebSocket server/broker and inference of an outcome that was never durably recorded are still absent.
+
+### Gap Assessment
+
+| Component | GJC | claw-code | Gap | Complexity |
+|-----------|-----|-----------|-----|------------|
+| Remote Session Router | 2,500 LOC | Local router/dispatch | Partial | High |
+| Invocation Reconciliation | 1,200 LOC | Durable invocation records | Partial | High |
+| Terminal Scope Tracking | 600 LOC | Implemented | — | Medium |
+| Async Event Streaming | 800 LOC | Local per-invocation stream | Partial | Medium |
+| Uncertain Outcome Recovery | 1,000 LOC | Unfinished records recovered as uncertain | Partial | High |
+| **Total** | **6,100 LOC** | **Session lifecycle slice implemented** | **Remote broker remains** | — |
+
+### Proposed Implementation
+
+**Owner Crate**: `sdk` (new, or extend `runtime`)
+
+**Module Structure** (`sdk/session/`):
+```
+sdk/session/
+├── mod.rs                (session routing and operation dispatch)
+├── reconciliation.rs    (uncertain → terminal recovery)
+├── terminal_scope.rs    (per-correlation state retention)
+└── events.rs            (ordered lifecycle event types)
+```
+
+**Integration Points**:
+- Bridge `runtime::Session` and `ConversationRuntime` into SDK lifecycle operations
+- Persist reconciliation and terminal-scope data alongside the session namespace
+- Emit lifecycle callbacks from `ConversationRuntime`
+
+**Size Estimate**: 2,500 LOC (Rust, new + modifications)

+
+## 4. TOOL CATALOG (55 Tools)
+
+### GJC Behavior (gajae-code Reference)
+
+**Source**: `packages/coding-agent/src/tools/` (55 tool files + shared harness)
+
+GJC implements **55 distinct tools** across multiple domains:
+- **File I/O**: `read`, `write`, `edit`, `search`, `find`
+- **Shell**: `bash`, `sleep`
+- **Task Delegation**: `task` (subagent spawning)
+- **Workflow**: `skill`, `skill_discovery`, `goal`, `ask`
+- **Search**: `search_tool_bm25` (semantic search discovery)
+- **Image**: `image_gen` (DALL-E), `image_tag_scan`
+- **Integration**: `web_fetch`, `web_search`, `custom_tool_fetch`
+- **Developer**: `notebook_edit`, `command_repl`, `shell_repl`, `powershell`
+- **Config**: `config_read`, `config_write` (settings, modes)
+- **Structured**: `model_registry`, `cost_calculator`, `settings_apply`
+- **Workflow Gates**: `workflow_gate_answer`, `workflow_plan_approve`
+- **Move**: `move_cwd`, `move_session`
+
+**Tool Execution Model**:
+1. Input deserialized from JSON schema
+2. Permission check (read-only vs. destructive)
+3. Tool invocation with typed inputs
+4. Structured output or error
+5. Result published to agent loop
+
+**Permission Gating**: Every tool has a `required_permission` (read-only, approve, unsafe).
+
+### claw-code Status
+
+**Current** (as of PR #3332/#3334/#3339): Partial. 35+ tools implemented.
+- PR #3332/#3334: Read tool enhanced with GJC-compatible line range selectors (`:50`, `:50-200`, `:50+150`, `:raw`, `:conflicts`, etc.)
+- PR #3339: `/tools` and `/info` commands implemented
+- Still missing: image_gen (DALL-E), ask (interactive), workflow_gate_*, command_repl, shell_repl, powershell, cost_calculator
+
+**Files**: `rust/crates/tools/src/lib.rs` (10,892 LOC, single file with all 55 spec + implementations)
+
+**Implemented Tools** (~35):
+- `read`, `write`, `edit`, `search`, `find`
+- `bash`, `sleep`
+- `task` (subagent spawning)
+- `skill`, `skill_discovery` (basic)
+- `bash_list_*, bash_check_*` (validation helpers)
+- `web_fetch`, `search_bm25` (basic)
+- `config_*` (read/write settings)
+- `notebooks` (edit, execute)
+- `goal` (basic ledger)

+## 5. SKILL DISCOVERY & INVOCATION
+
+### GJC Behavior (gajae-code Reference)
+
+**Source**: `packages/coding-agent/src/tools/skill-discovery.ts`, `packages/coding-agent/src/tools/skill.ts`, `packages/coding-agent/src/sdk-skills/`
+
+GJC supports **dynamic skill loading** with:
+- **Discovery**: `skill_discovery` tool scans `.gjc/skills/`, project `.gjc/skills/`, bundled skills
+- **Frontmatter Parsing**: YAML headers in `SKILL.md` define metadata (name, description, use conditions)
+- **Invocation**: `skill` tool loads and executes a named skill (skill name + args)
+- **Skill Execution**: Skill = subprocess call to `gjc /skill:<name>` with args
+- **Bundled Skills**: `autoresearch`, `deep-interview`, `ralplan`, `ultragoal`
+- **Project Skills**: Discoverable from `.gjc/skills/*/SKILL.md`
+- **User Skills**: Discoverable from `~/.gjc/skills/*/SKILL.md`
+
+**Skill Metadata**:
+```yaml
+# /skill:my-skill
+# description: What this skill does
+# scope: project | user | bundled
+# requires: List of capabilities
+```
+
+**Skill Discovery Result**:
+```json
+{
+  "name": "skill-name",
+  "description": "...",
+  "path": "...",
+  "bundled": true | false,
+  "scope": "project" | "user" | "bundled"
+}
+```
+
+### claw-code Status
+
+**Current**: Basic. Skill discovery exists but limited to filesystem scanning.
+
+**Files**:
+- `rust/crates/tools/src/lib.rs` (skill_discovery + skill dispatch, ~200 LOC)
+- `rust/crates/runtime/src/prompt.rs` (skill loading in prompts, ~100 LOC)
+
+**Implementation**:
+- Scans `.claw/skills/` directory for `SKILL.md` files
+- Parses frontmatter (basic YAML)
+- Returns discovery results as JSON
+- `skill` tool invokes skill as subprocess
+
+**Missing**:
+- Bundled skill registry (autoresearch, deep-interview, ralplan, ultragoal)
+- Project + user skill discovery hierarchy
+- Frontmatter validation and standardization
+- Skill chaining (`skill()` tool to invoke another skill from within a skill)
+- Skill state persistence (workflow handoff)
+
+### Gap Assessment

+
+**Module Structure**:
+```
+rust/crates/tools/src/

+├── skill_execution.rs       (subprocess dispatch, state handoff)
+├── bundled_skills.rs        (registry of autoresearch, deep-interview, ralplan, ultragoal)
+└── skill_state.rs           (workflow handoff serialization)
+```
+
+**Size Estimate**: 1,400 LOC (Rust)
+
+**Integration**:
+- Extend `skill_discovery` tool to search three scopes (bundled, project, user)
+- Add `skill` tool support for chaining (returning another skill invocation)
+- Store workflow state in durable files for handoff

+
+## 6. SETTINGS & CONFIGURATION
+
+### GJC Behavior (gajae-code Reference)
+
+**Source**: `packages/coding-agent/src/config.ts`, `packages/coding-agent/src/sdk/host/session-runtime.ts`
+
+GJC supports **settings override** at multiple levels:
+1. **Global Settings**: `~/.gjc/config.json` (user defaults)
+2. **Session Settings**: per-session override via `turn.create` or `turn.prompt` input
+3. **Runtime Override**: `settings` field in SDK request frames
+4. **Setting Categories**: 
+   - **Model**: `modelName`, `modelTemperature`, `modelMaxTokens`
+   - **Behavior**: `allowance`, `permissions.*`, `features.*`
+   - **UX**: `theme`, `shell`, `notification*`
+   - **Advanced**: `memory.context`, `memory.compression`, `cost.*`
+
+**Config Schema**: Typed with JSON schema validation per setting
+
+**Permission Modes**: 
+- `read_only` (no execution)
+- `approve` (interactive approval)
+- `unsafe` (no gates)
+
+### claw-code Status
+
+**Current**: Partial. Config exists but no session-level override or setting propagation.
+
+**Files**:
+- `rust/crates/runtime/src/config.rs` (3,894 LOC, largest file in runtime)
+- `rust/crates/runtime/src/config_validate.rs` (validation helpers)
+
+**Implementation**:
+- Reads `.claw/config.json` at startup
+- Stores global settings (model, permissions, plugins, features)
+- No session-level override
+- No setting propagation through tool execution
+- No typed setting validation against schema
+
+**Missing**:
+- Per-session setting override (session-specific model, permissions)
+- Setting propagation to all tool invocations
+- Dynamic setting application (e.g., changing model mid-session)
+- Setting schema validation
+- Config hotreload (changes without restart)
+
+### Gap Assessment
+
+| Component | GJC | claw-code | Gap | Complexity |
+|-----------|-----|-----------|-----|------------|
+| Setting Schema Definition | 300 LOC | — | 100% | Low |

+
+**Additions to config.rs**:
+- Setting schema registry
+- Session setting override struct
+- Setting applicator (merge global + session + override)
+- Hotreload support (watch config file, signal on change)
+
+**Size Estimate**: 500 LOC (new code, mostly schema + applicators)

+
+## 7. HOOKS & PLUGINS
+
+### GJC Behavior (gajae-code Reference)
+
+**Source**: `packages/coding-agent/src/hooks.ts`, `packages/coding-agent/src/plugin_lifecycle.ts`
+
+GJC provides **5 hook points**:
+- `on_session_created`: After session starts
+- `on_prompt_received`: Before agent loop begins
+- `on_tool_use`: Before tool invocation
+- `on_tool_result`: After tool completes
+- `on_session_ended`: Before session cleanup
+
+**Plugin System**:
+- Plugins are shell scripts or binaries in `.claw/plugins/`
+- Each plugin implements hook handlers (exit code + JSON output)
+- Plugin registry stored in config
+
+### claw-code Status
+
+**Current**: Existing and comprehensive.
+
+**Files**:
+- `rust/crates/runtime/src/hooks.rs` (L155)
+- `rust/crates/runtime/src/plugin_lifecycle.rs`
+- `rust/crates/plugins/src/` (plugin manager)
+
+**Implementation**: Hooks fully implemented; plugin system working.

+
+### GJC Behavior (gajae-code Reference)
+
+**Source**: gajae-code root + `docs/` (AGENTS.md files at multiple levels)
+
+GJC loads **directory-specific rules** from `AGENTS.md` files:
+- **Root AGENTS.md**: Project-level knowledge base
+- **Directory AGENTS.md**: Directory-specific rules override parent
+- **Rules Loaded**: Automatically prepended to system prompt during agent reasoning
+- **Hierarchy**: Deepest (most specific) rules override higher level
+
+**Rule Content**:
+- Code organization and conventions
+- Tool restrictions (never use X in Y context)
+- Testing requirements
+- Deployment/safety gates
+- Architecture decisions
+
+### claw-code Status
+
+**Current**: Existing and matching GJC.

+- Root: `AGENTS.md`
+- Crate-level: `rust/crates/*/AGENTS.md`
+- Implementation: `rust/crates/runtime/src/` (loads rules)
+
+**Implementation**: Rules loaded and applied to prompts.

+
+### GJC Behavior (gajae-code Reference)
+
+**Source**: `packages/coding-agent/src/tools/task.ts`, `packages/coding-agent/src/task/`
+
+GJC's **subagent system** enables parallel task execution:
+- **task Tool**: Spawn parallel subtasks with independent context
+- **Task States**: spawning, running, succeeded, failed
+- **Task Isolation**: Each task has isolated session, permissions, context
+- **Task Coordination**: `irc` tool for live inter-task communication
+- **Task Monitoring**: `task.inspect`, `task.list`, `task.cancel`
+- **Artifact Sharing**: Tasks share artifact URLs but not direct state
+
+**Task Spawning**:
+```json
+{
+  "agent": "executor|architect|planner",
+  "tasks": [
+    {
+      "id": "task-1",

+# GJC Tool Semantics Alignment: Phase 1 (read/edit/search/find)
+
+**Status**: Implementation plan  
+**Issue**: #3323  
+**Scope**: Slice 2.1 - Tool catalog semantic parity for read/edit/search/find  
+**Target**: Ship in batches with focused PRs
+
+---
+
+## 1. EXECUTIVE SUMMARY
+
+This document details the semantic gaps between claw-code's current tool implementations and GJC's (gajae-code) reference implementations for the highest-value tools: **read**, **edit**, **search**, and **find**.
+
+### Key Gaps
+
+| Tool | Current (claw-code) | Target (GJC) | Gap | Complexity |
+|------|-----|--------|-----|------------|
+| **read** | offset/limit pagination | Line selectors (`:L-L+N`), raw mode, truncation footers | High | Medium |
+| **write** | Simple file replacement | Full replacement semantics (matching GJC) | Low | Low |
+| **edit** | String replacement (old→new) | String replacement with rich patch output | Low | Low |
+| **find** (glob) | Pattern expansion only | Recursive glob with filtering | Low | Low |
+| **search** (grep) | Regex search with context | Regex with context + advanced filtering | Low | Low |
+
+---
+
+## 2. GJC TOOL SEMANTICS REFERENCE
+
+### 2.1 READ Tool
+
+**Source**: `gajae-code/packages/coding-agent/src/tools/read.ts` (3,500+ LOC)
+
+#### Input Schema
+```typescript
+{
+  path: string;           // File path (relative or absolute)
+  offset?: number;        // Line offset (for pagination)
+  limit?: number;         // Lines to read (for pagination)
+  // GJC extensions (missing in claw-code):
+  selector?: string;      // Line range syntax:
+                          // ":50" = line 50 onward
+                          // ":50-200" = lines 50-200 inclusive
+                          // ":50+150" = 150 lines starting at line 50
+                          // ":raw" = full file verbatim
+                          // ":conflicts" = git merge conflicts only
+  truncationDirection?: "head" | "tail" | "both";  // Which end to keep
+  maxSummaryBytes?: number;  // Summary budget (default 50KB)
+  maxSummaryLines?: number;  // Summary budget (default 20K lines)
+}
+```
+
+#### Output Structure
+```json
+{
+  "file": {
+    "path": "src/main.rs",
+    "content": "...",
+    "totalLines": 500,
+    "totalBytes": 12345,
+    "truncatedBy": "lines" | "bytes" | "middle" | null,
+    "displayMode": "summarized" | "raw" | "receipt"
+  },
+  "truncationFooter": "[Showing lines 1-50 of 500; re-read ...]"
+}
+```
+
+#### Key Behaviors
+
+1. **Line Range Selectors** (`:selector` syntax)
+   - `:50` = start at line 50
+   - `:50-200` = lines 50-200 inclusive
+   - `:50+150` = 150 lines starting at 50
+   - `:50+1` = exactly one line
+   - `:5-16,960-973` = multiple ranges
+   - `:raw` = full verbatim
+   - `:conflicts` = git merge conflicts
+
+2. **Truncation Modes**
+   - Default: 50KB bytes limit, 20K lines limit
+   - Direction: `head` (keep start), `tail` (keep end), `both` (keep both ends)
+   - Footer includes recovery hint (e.g., "`re-read path:1-9999` for verbatim")
+
+3. **Structural Summarization**
+   - Code: collapse function bodies to `..` or `…` (merged brace pairs)
+   - Prose: preserve full lines, truncate at word boundaries
+   - Special files: documents (PDF, DOCX, XLSX) converted via markit
+
+4. **Archive Support**
+   - `.tar`, `.tar.gz`, `.tgz`, `.zip`: member read with `archive.ext:path/inside`
+   - SQLite: `.sqlite:table` or `.sqlite:table:key` queries
+   - Line ranges apply to archive members
+
+5. **Output Formatting**
+   - Anchored output: Line prefixes with source line numbers and hash anchors
+   - Optional hash lines: Marks structural boundaries (`# pragma`, function start, etc.)
+   - Prose column cap: Long lines wrapped/truncated at column limit
+
+### 2.2 EDIT Tool
+
+**Source**: `gajae-code/packages/coding-agent/src/tools/edit.ts`
+
+#### Input Schema
+```typescript
+{
+  path: string;           // File to edit
+  old_text: string;       // Text to replace (required for edit)
+  new_text: string;       // Replacement text
+  all?: boolean;          // Replace all occurrences (default: first only)
+}
+```
+
+#### Output Structure
+```json
+{
+  "file": {
+    "path": "src/main.rs",
+    "editCount": 1,
+    "beforeSize": 12345,
+    "afterSize": 12400
+  },
+  "patch": [
+    {
+      "type": "replace",
+      "lineStart": 50,
+      "lineEnd": 55,
+      "before": "old content",
+      "after": "new content",
+      "context": {"before": 3, "after": 3}
+    }
+  ]
+}
+```
+
+#### Key Behaviors
+
+1. **Exact Match Required**: `old_text` must match exactly (no fuzzy matching)
+2. **Smallest Replacement**: Use smallest unique old_text that identifies the change
+3. **All-or-Nothing**: Either all occurrences replaced or none (no partial)
+4. **Patch Metadata**: Line numbers, context, before/after preserved
+
+### 2.3 SEARCH Tool
+
+**Source**: `gajae-code/packages/coding-agent/src/tools/search.ts`
+
+#### Input Schema
+```typescript
+{
+  pattern: string;        // Regex pattern
+  paths?: string[];       // Files/dirs to search
+  context?: number;       // Context lines before/after (default: 2)
+  i?: boolean;            // Case-insensitive
+  glob_exclude?: string[];  // Patterns to skip
+  file_type?: string;     // Filter by extension
+  limit?: number;         // Max results
+  truncation?: "head" | "tail" | "both";
+}
+```
+
+#### Output Structure
+```json
+{
+  "matches": [
+    {
+      "file": "src/main.rs",
+      "lineNumber": 42,
+      "line": "fn process() {",
+      "before": ["// Process data", ""],
+      "after": ["  // Implementation", ""]
+    }
+  ],
+  "summary": "Found 5 matches in 3 files"
+}
+```
+
+### 2.4 FIND Tool
+
+**Source**: `gajae-code/packages/coding-agent/src/tools/find.ts`
+
+#### Input Schema
+```typescript
+{
+  paths: string[];        // Glob patterns
+  timeout?: number;       // Timeout in seconds (default: 5)
+  gitignore?: boolean;    // Respect .gitignore (default: true)
+  hidden?: boolean;       // Include hidden files (default: true)
+  limit?: number;         // Max results (default: 1000)
+}
+```
+
+#### Output Structure
+```json
+{
+  "files": [
+    {
+      "path": "src/main.rs",
+      "modified": "2026-10-13T12:34:56Z",
+      "size": 12345

+
+**Size Estimate**: 500 LOC  
+**Complexity**: Low-Medium
+
+---
+
+## 5. VERIFICATION STRATEGY
+
+Each batch will include:
+1. **Semantic Tests**: Verify tool inputs/outputs match GJC reference
+2. **Edge Case Tests**: Line ranges, truncation, archives, etc.
+3. **Integration Tests**: End-to-end with claw CLI
+4. **Parity Shadow Test**: Run same inputs against both GJC and claw-code, compare outputs
+
+---
+
+## 6. ROLLOUT SCHEDULE
+
+- **Batch 1 (READ)**: Week 1 - Enable most impactful tool first
+- **Batch 2 (EDIT)**: Week 1-2 - Quick follow-up
+- **Batch 3 (SEARCH/FIND)**: Week 2 - Lower priority but valuable for discoverability

 Routing notes:

 - Use the `openai/` prefix for OpenAI-compatible gateways when you need prefix routing to win over ambient Anthropic credentials, for example `--model "openai/gpt-4.1-mini"` with OpenRouter.
- For local servers, prefer the exact model ID reported by the server (`qwen3:latest`, `llama3.2`, `Qwen/Qwen2.5-Coder-7B-Instruct`, etc.). If your local gateway exposes slash-containing IDs, use that exact slug.
- If you have multiple provider keys in your environment, remove unrelated keys while smoke-testing a local route or choose a model prefix that unambiguously selects the intended provider.
+- For local servers, prefer the exact model ID reported by the server (`qwen3:latest`, `llama3.2`, etc.). If your local gateway exposes slash-containing IDs, prefix the exact slug with `local/` so Claw routes through OpenAI-compatible transport while sending the rest verbatim, for example `--model "local/Qwen/Qwen2.5-Coder-7B-Instruct"`.
+- When `OPENAI_BASE_URL` points at a loopback or private-network address (`localhost`, `127.0.0.1`, `10.x`, `192.168.x`, `172.16-31.x`), Claw accepts **any** non-empty model name — bare aliases like `mistral` work with no dot, colon, or slash required. This covers LM Studio and llama.cpp server setups that register models under a plain `--alias`, not just Ollama-style tagged names (`llama3.2`, `qwen2.5-coder:7b`). `local/` is still needed only to preserve slash-containing IDs verbatim (e.g. Hugging Face repo IDs for vLLM/mlx-lm).
+- Against a remote/hosted OpenAI-compatible gateway (not local/private), Claw keeps the stricter `provider/model` or dot/colon-tag requirement so a mistyped bare name doesn't silently route to a paid hosted API.
 - Tool workflows need model/server support for OpenAI-compatible tool calls. Plain prompt smoke tests can pass even when slash/tool workflows still fail because the server returns an incompatible tool-call shape.

+# Nix flake development environment
+
+This repository includes a **`flake.nix`** for reproducible development environments on NixOS and systems with Nix installed.
+
+## Prerequisites
+
+- **Nix** (version 2.4 or later with flakes support enabled)
+- **direnv** (optional, for automatic environment loading via `.envrc`)
+
+To verify Nix is installed and flakes are enabled:
+
+```bash
+nix --version
+nix flake --help
+```
+
+If flakes are not enabled, add this to your `~/.config/nix/nix.conf`:
+
+```
+experimental-features = nix-command flakes
+```
+
+## Quick start
+
+### Enter the development environment
+
+**Option 1: Using `nix flake`** (without direnv)
+
+```bash
+nix flake update              # Update inputs (optional, pins nixpkgs)
+nix develop                    # Enter default dev shell
+nix develop .#full             # Enter full dev shell with extra tools
+exit                           # Leave the shell
+```
+
+**Option 2: Using direnv** (automatic on directory entry)
+
+```bash
+direnv allow                   # Trust the .envrc file (one-time setup)
+cd .                           # Direnv reloads the flake automatically
+```
+
+When you leave the repository directory, the environment is automatically unloaded.
+
+## Development shells
+
+The flake provides two development shells:
+
+### `default` (minimal)
+
+```bash
+nix develop
+```
+
+Includes:
+- Rust (stable, latest)
+- Rust source code (`rust-src`)
+- `cargo-edit` (dependency management helpers)
+- `cargo-expand` (macro expansion tool)
+- `cargo-watch` (file watcher for incremental builds)
+- Build tools: `pkg-config`, `openssl`, `git`, `ca-certificates`
+
+### `full` (with extra tooling)
+
+```bash
+nix develop .#full
+```
+
+Includes everything from `default` plus:
+- `clippy` (linter)
+- `rustfmt` (code formatter)
+- `mold` (fast linker)
+- `lldb` (debugger)
+
+## Building the claw binary
+
+### With the dev environment
+
+```bash
+nix develop
+cd rust
+cargo build -p rusty-claude-cli
+```
+
+### Directly with `nix build`
+
+```bash
+nix build .#claw          # Build the claw binary
+nix build                 # Same as .#claw (default package)
+```
+
+The compiled binary is symlinked to `./result/bin/claw`.
+
+## Running common tasks
+
+Once in the dev shell:
+
+```bash
+# Format code
+cd rust
+cargo fmt
+
+# Run clippy linter
+cargo clippy --workspace --all-targets -- -D warnings
+
+# Run all tests
+cargo test --workspace
+
+# Run tests for a specific crate
+cargo test -p rusty-claude-cli
+
+# Build with optimizations
+cargo build --release -p rusty-claude-cli
+```
+
+## Environment variables
+
+The flake automatically sets:
+
+- `RUSTUP_TOOLCHAIN=stable` — uses stable Rust from nixpkgs
+- Standard Rust build flags are inherited from the environment
+
+For development, the minimal dev shell includes a helpful message on entry:
+
+```
+Claw Code development environment
+Run 'cargo build -p rusty-claude-cli' to build the claw binary
+Run 'cargo test --workspace' to run tests
+Run 'scripts/fmt.sh' to format code
+```
+
+## Troubleshooting
+
+### `command not found: nix`
+
+Nix is not installed. Install it from [nixos.org/download.html](https://nixos.org/download.html).
+
+### `error: experimental Nix feature 'flakes' is disabled`
+
+Enable flakes in your Nix configuration (`~/.config/nix/nix.conf` or `/etc/nix/nix.conf`):
+
+```
+experimental-features = nix-command flakes
+```
+
+### `error: ... does not provide attribute 'claw'`
+
+The flake structure may have changed. Try updating:
+
+```bash
+nix flake update
+nix flake check
+```
+
+### Rebuilds are slow after updating dependencies
+
+Cargo will recompile dependencies if `Cargo.lock` changes. This is expected:
+
+```bash
+nix build --rebuild
+```
+
+### `cache lock file needs to be updated`
+
+The Cargo.lock in `rust/` needs to be committed. Run:
+
+```bash
+cd rust
+cargo generate-lockfile
+git add Cargo.lock
+git commit -m "update: Cargo.lock"
+```
+
+## Integration with other tools
+
+### IDE integration (VS Code, IntelliJ, etc.)
+
+Many IDEs can detect and use Nix environments. Direnv integration is recommended:
+
+1. Install the direnv extension
+2. Enable `direnv` shell integration in your IDE
+3. Run `direnv allow` in the repository
+
+Your IDE will automatically use the correct Rust toolchain and dependencies from the flake.
+
+### CI/CD
+
+For GitHub Actions, consider using [cachix/install-nix-action](https://github.com/cachix/install-nix-action) to set up Nix on the runner:
+
+```yaml
+- uses: cachix/install-nix-action@v18
+  with:
+    nix_path: nixpkgs=channel:nixos-unstable
+    extra_nix_config: "experimental-features = nix-command flakes"
+
+- run: nix develop -c cargo test --workspace
+```

+# From Claw Code to a Personal AI Assistant (Life OS)
+
+This document turns the current “developer CLI agent” direction into a concrete path toward a **personal AI assistant**: a multi-channel interface (chat/voice), personal memory (RAG for life), tool/action integrations (MCP + plugins), proactivity (OmX-style loops), and long-lived identity (sessions + profile).
+
+It is intentionally pragmatic: each section has **MVP scope**, **next step**, and **evolution**.
+
+---
+
+## 1) Interface: out of the terminal
+
+### Goal
+Make `claw` usable without opening an IDE or terminal — from a phone, from chat, and eventually by voice.
+
+### MVP
+- **Chat bridge**: a small service that relays messages from **Discord** (primary) or Telegram to `claw` / `claw-analog`.
+  - Treat the chat thread as the “front-end”, and `claw` as the execution runtime.
+  - Map a channel/thread to a **session id** (resume/append).
+- **Basic UX**: slash-like commands in chat:
+  - `/prompt …`, `/resume latest`, `/status`, `/cost`, `/help`
+  - “safe mode” defaults (read-only) unless elevated explicitly.
+
+### Next step
+- **Voice**:
+  - Speech-to-text input (e.g. Whisper-class STT) into the same chat bridge.
+  - Text-to-speech output for hands-free feedback.
+
+### Evolution
+- Multi-modal: attachments (images/PDF) routed into ingest/personal memory.
+- Presence and notifications: summaries pushed back into chat.
+
+---
+
+## 2) Memory: from “RAG for code” to “RAG for life”
+
+### Goal
+Let the assistant answer personal questions and make decisions using *your* long-term context, not only the current repo.
+
+### MVP
+- Extend ingestion inputs beyond git workspaces:
+  - Notes (Markdown), exported chats, simple text logs.
+  - PDFs (initially text extraction outside Rust is OK; later: built-in pipeline).
+- Keep a clear separation:
+  - **Work RAG** (code/workspaces)
+  - **Personal RAG** (notes, plans, history)
+
+### Next step
+- Evolve `retrieve_context` into a **multi-source retrieval tool**:
+  - “where to search” selector (work/personal/both)
+  - metadata filters (source, date ranges, tags)
+
+### Evolution
+- Incremental ingestion + event-based updates (watch folders, chat events).
+- Better stores (ANN/Qdrant/etc) when scale demands it.
+
+---
+
+## 3) Hands: tools, MCP, plugins
+
+### Goal
+The assistant is valuable because it can **do** things, not only talk.
+
+### MVP
+- Wire in external systems via **MCP servers**:
+  - Calendar, notes (Notion), email, task trackers, smart home (as available).
+- Establish a convention for “personal skills”:
+  - a dedicated directory (e.g. `.claw/skills/`) for user-specific automations
+  - small, composable tools (digest, budgeting, reminders) rather than monoliths
+
+### Next step
+- “Tool discovery” UX: list available MCP/tools/skills directly from chat.
+- Permission boundaries per tool category (read vs write, destructive actions require explicit confirmation).
+
+### Evolution
+- Plugin marketplace flows for reusing “skills”.
+- Audit logging and replay of actions.
+
+---
+
+## 4) Proactivity: OmX-style loops
+
+### Goal
+Move from reactive “answer me” to proactive “notice + prepare + propose + execute”.
+
+### MVP
+- A scheduled runner that periodically:
+  - checks inbox/notifications
+  - extracts actionable tasks
+  - drafts responses
+  - posts a short digest to chat
+
+### Next step
+- Multi-agent patterns (Architect/Executor/Reviewer) for higher reliability:
+  - executor proposes actions
+  - reviewer validates safety and correctness
+  - only then does the bridge run the write/action tool
+
+### Evolution
+- Event-driven triggers (webhooks) instead of only cron.
+- “Autopilot” modes with bounded scopes (time, tools, spend limits).
+
+---
+
+## 5) Long-lived identity: sessions + profile
+
+### Goal
+Make the assistant feel continuous and personalized across days/weeks.
+
+### MVP
+- Default to resuming the latest session (`--resume latest`-style behavior).
+- Use a short, user-owned profile/system-prompt for tone and preferences.
+
+### Next step
+- Separate:
+  - “personality” (style, preferences)
+  - “memory” (facts, history)
+  - “policies” (permissions, safety rules)
+
+### Evolution
+- Multiple personas (work/personal) with explicit switching.
+- Transparent memory controls (“forget this”, “store this”).
+
+---
+
+## Suggested milestone sequence
+
+1. **Discord bridge + session mapping** (no new AI capabilities; just distribution).
+2. **Personal ingest source #1** (notes folder) + retrieval selector (personal/work).
+3. **One MCP integration** (calendar or notes) + a single “daily digest” skill.
+4. **Scheduled digest loop** (cron) with bounded permissions.
+5. **Voice input/output** on top of the same bridge.

+# RAG и веб‑UI: архитектура и фазы
+
+Цель: **не** раздувать `claw-analog` и основной `claw` — вынести индексацию и (позже) UI в отдельные процессы с явными HTTP/MCP контрактами.
+
+## Принципы
+
+1. **RAG как сервис** — отдельный бинарь (сейчас `claw-rag-service`), свой жизненный цикл, свои секреты (embedding API), своё хранилище.
+2. **Агент только вызывает retrieval** — в **`claw-analog`** инструмент **`retrieve_context`** → HTTP `POST {RAG_BASE_URL}/v1/query` (база без суффикса `/v1`); лимиты **`rag_timeout_secs`**, **`rag_top_k_max`** в `.claw-analog.toml`; ответ для модели — фрагменты с `path` + `snippet` + `score`.
+3. **Веб‑UI** — минимальная страница **`GET /`** в `claw-rag-service` (stats + форма `POST /v1/query`); чат с моделью и «переиндексировать» из браузера — при необходимости позже.
+
+## Компоненты (целевая картина)
+
+```text
+┌─────────────────┐     POST /v1/query      ┌──────────────────────┐
+│  claw-analog    │ ──────────────────────►│  claw-rag-service    │
+│  (+ tool)       │◄──────────────────────│  (embed + vector DB) │
+└─────────────────┘     JSON hits          └──────────┬───────────┘
+                                                      │
+                                             ingest (watch / CLI)

+                                             workspace files / git tree
+```
+
+- **Индексация**: отдельная команда или воркер (chunking, хеш файла, инкремент). Хранилище: на старте SQLite + `sqlite-vec` / файловый эмбеддинг-кэш; при росте — Qdrant/Chroma в Docker.
+- **Эмбеддинги**: HTTP к OpenAI/Anthropic-совместимому embedding endpoint или локальная модель (отдельное решение по лицензии и размеру).
+- **Веб‑UI**: авторизация (минимум: токен + reverse proxy), SSE или WebSocket для стрима ответа модели; UI **не** владеет секретами провайдера, если продукт так решит — прокси через бэкенд.
+
+## Текущая реализация
+
+Крейт **`rust/crates/claw-rag-service`** (из каталога `rust/`):
+
+### HTTP
+
+- `GET /` — одностраничный UI (встроенный `static/index.html`): счётчики из `/v1/stats`, поиск через `/v1/query`.
+- `GET /health` — `ok`.
+- `GET /v1/stats` — `{ "chunks": N, "phase": "1-sqlite" }` (если БД ещё нет: `chunks: 0`, `phase`: `1-sqlite-no-db`).
+- `POST /v1/query` — тело `{"query":"...", "top_k":8}`; ответ `{"hits":[{"path","snippet","score"}], "phase":"1-sqlite"|"1-sqlite-empty"|"1-sqlite-no-db"}`.
+
+Поиск: **линейный обход** всех векторов в SQLite (MVP; для больших репозиториев планировать Qdrant/sqlite-vec или батчевый ANN).
+
+### Индексация (фаза 1)
+
+```powershell
+cd D:\path\to\claw-code-main\rust
+$env:OPENAI_API_KEY = "sk-..."
+cargo run -p claw-rag-service -- ingest -w D:\path\to\repo --db D:\path\to\index.sqlite
+cargo run -p claw-analog -- ...   # при RAG_BASE_URL или rag_base_url в TOML — инструмент retrieve_context
+```
+
+Переменные окружения:
+
+- **`OPENAI_API_KEY`** или **`CLAW_RAG_OPENAI_API_KEY`** — для вызова `POST …/embeddings`.
+- **`CLAW_RAG_EMBEDDING_BASE_URL`** — по умолчанию `https://api.openai.com/v1`.
+- **`CLAW_RAG_EMBEDDING_MODEL`** — по умолчанию `text-embedding-3-small`.
+- **`CLAW_RAG_DB`** — путь к SQLite (у ingest/`serve`; у `serve` есть default `.claw-rag/index.sqlite`).
+- **`CLAW_RAG_PORT`** — порт HTTP (по умолчанию `8787`).
+- **`CLAW_RAG_MOCK_PROVIDERS=1`** — детерминированные вектора без сети (для тестов CI).
+
+Запуск сервера: `cargo run -p claw-rag-service` или `cargo run -p claw-rag-service -- serve --db path\to\index.sqlite`.
+
+### Дальше по фазам
+
+| Фаза | Содержание |
+|------|------------|
+| 1 | ~~Ingest + SQLite + embeddings~~ (базово сделано; улучшения: инкремент, ANN, Docker-векторка). |
+| 2 | ~~Инструмент `retrieve_context`~~: `RAG_BASE_URL` / `rag_base_url`, `rag_timeout_secs`, `rag_top_k_max` в `.claw-analog.toml`. |
+| 3 | ~~Минимальный UI~~: `GET /` + те же `/v1/*` (дальше: чат, кнопка re-index из UI). |

+# Asolaria for claw-code — a compact, tamper-evident wire format + addressing model for the agent event firehose
+
+A **self-contained, additive example** (no changes to claw-code core). It contributes one reproducible
+Rust benchmark plus a design write-up, aimed at the part of claw-code that moves the most bytes:
+**clawhip** — the event router that watches git commits, tmux sessions, GitHub PRs and agent-lifecycle
+events and pushes routing *out* of the agent context window so agents stay focused on implementation.
+
+The technique is from **Asolaria**, a multi-agent fabric built and operated *with* a claw-code-style
+autonomous harness. We contribute the parts that are (a) genuinely useful to a no-human-intervention
+harness and (b) **reproducible on your machine** — and we explicitly tag the parts that are
+architecture/vision, so nothing here backfires when an AI reviewer re-runs it.
+
+> **The bigger picture (tagged: vision/architecture, not a benchmark):** Asolaria's end goal is to make
+> *every device a surface* for one self-improving fabric — the device renders/addresses at ~0 local
+> token cost while the heavy reasoning is paged onto larger compute. You don't need to buy any of that
+> to use what's below; the wire format and 8-byte addressing stand on their own, measured.

+clawhip's event stream is high-rate and, today, JSON text. Re-encoding the same records as a
+fixed-width binary wire (`json=0`) and optionally folding a SHA-256 hash-chain over them gives, on
+**200,000** agent-lane-event records (measured; ratios are the reproducible part, ns vary by CPU):
+
+| Per record | JSON (text) | `json=0` binary | binary + SHA-256 chain |
+|---|---|---|---|
+| **Wire size** | 153.2 B | **33.0 B — 4.64× smaller** | **65.0 B — 2.36× smaller** |
+| **Encode** | ~307 ns | **~28 ns — ~11× faster** | binary + one hash |
+| **Decode** | ~468 ns (parse) | **~0.8 ns — decode ≈ free** | field read = pointer offset |
+| **Integrity** | none | none | **per-record tamper-evident** |
+
+- The lane is addressed by its **8-byte FNV-1a-64 handle**, so the lane string is never repeated;
+  fields are fixed-width little-endian, so decode is a pointer offset, not a parse.
+- The chain link is `link_n = SHA256(link_{n-1} ‖ record_n)`. It adds **exactly +32 B** → 65.0 B/rec,
+  and any insert / delete / reorder / single-bit edit breaks the fold from that record on; a one-pass
+  verify **localizes the first altered record** (the bundled bench demonstrates this).
+- **Honest nuance (not a compression claim):** `gzip` narrows the *raw-size* gap (crypto links are
+  high-entropy by design). The durable wins are **uncompressed wire size, decode speed, and
+  integrity** — the IPC / mmap / tail-replay path and a tamper-evident audit trail — not archival
+  compressibility.
+
+See [§6 Reproduce](#6-reproduce).
+
+---
+
+## 2. The addressing capacity (LOGICAL / CANON — address *space*, not materialized things)
+
+Asolaria addresses subsystems with **BEHCS-1024**: a radix-1024 glyph tuple over a **60-dimension**
+coordinate. One ~12-byte tuple names a whole subsystem (room / lane / agent) and rehydrates losslessly
+to its full ~6,184-byte descriptor *via the fabric store*.
+
+- **DERIVABLE (arithmetic):** the 12-byte wire handle alone is a **2⁹⁶ ≈ 7.9×10²⁸** namespace —
+  astronomically past any harness demand (a lifetime of events ≈ 10⁹–10¹²), so agents mint ids
+  independently with effectively zero collision risk and no coordinator.
+- **LOGICAL / CANON (do NOT re-run as a count):** the full 60-D space is `(1024⁶⁰)⁵⁰ ≈ 10⁹⁰³⁰` —
+  the address space the scheme can *name*, not a count of things that exist.
+- **Addressing, measured in-fabric (NOT reproduced by this example):** a ~12-byte glyph indexing its
+  ~6,184-byte descriptor is **520:1** — *addressing* (the tuple points into a store), **not** a codec
+  you can rehydrate from 12 bytes alone. We cite it; we do not claim the local bench reproduces it.
+
+> **Anti-overclaim:** 12 bytes do **not** enumerate 10⁹⁰³⁰ values (96 bits is ~10²⁸·⁹). The 10⁹⁰³⁰ is
+> the *scheme's* naming ceiling, not the wire handle's cardinality, and not a count of materialized
+> entities.
+
+---
+
+## 3. Per-component benefit to claw-code
+
+Tags mark which lines are re-runnable here vs architecture.
+
+- **8-byte FNV-1a-64 content-handle** [8-byte width MEASURED; content-addressing architecture] — a tmux
+  session name / `owner/repo#1204` / worktree path (30–120+ B) collapses to one fixed 8-byte handle
+  agents pass instead of prose; "did we already report this commit?" is an 8-byte equality check.
+  *(FNV-1a-64 is a non-cryptographic dedup/address hash — tamper-evidence is the SHA-256 chain's job.)*
+- **json=0 binary wire** [MEASURED §1] — 4.64× smaller, decode≈free for clawhip's high-rate event log;
+  fixed width → O(1) seek / tail-follow / byte-range replay (record N at offset `N*width`).
+- **BEHCS event envelope** [size/speed MEASURED; ordering architecture] — each event carries
+  `lane(8B) + seq + lamport + hash`; a stable total order `(lamport, lane, seq)` makes replay
+  deterministic across racing agents; a dropped event shows as a seq gap, a double-delivery as a dup.
+- **60-D tuple addressing** [§2] — reference a whole subsystem by a tiny handle instead of inlining a
+  descriptor clawhip just evicted; sibling lanes share a coordinate prefix (route a lane-family by
+  prefix, not an id list).
+- **SHA-256 hash-chain** [MEASURED §1/§6] — a no-human-intervention harness gets a tamper-evident audit
+  trail for +32 B/rec; the chain breaks on any mutation and a one-pass recompute localizes the first
+  bad record.
+- **Stubbed rooms as RAM** [handle MEASURED; demand-paging architecture/vision] — a "room" (open files,
+  prior reasoning, sub-task ledger) lives as an out-of-context descriptor stub keyed by an 8-byte
+  handle; only the needed slice hydrates into context. Footprint scales with *active* agents, not
+  total. *(Paging against larger compute is the architecture model, not a deployed cluster.)*
+
+---
+
+## 4. Concrete shape on the wire
+
+One BEHCS-enveloped clawhip event (65.0 B binary, chained):
+
+```
+lane    = 0xA3F1C2D4E5B60718   # 8-byte FNV-1a-64 handle for "executor-7/git-watch"
+seq     = 4271                 # per-lane monotonic: 4270->4272 = dropped; repeated 4271 = dup
+lamport = 98142                # deterministic cross-lane order, no wall clock
+rec     = <33 B fixed-width payload>          # vs 153.2 B as JSON
+link    = SHA256(prev_link ‖ rec)             # 32 B; editing any past rec breaks every later link
+```
+
+---
+
+## 5. Where this comes from
+
+Asolaria (public Host-8 lane — the council modules + this technique live here):
+**https://github.com/JesseBrown1980/asolaria-federation-1024**
+
+A multi-agent system built/operated with a claw-code-style autonomous harness. This PR contributes only
+the additive, reproducible slice.
+
+---
+
+## 6. Reproduce
+
+```bash
+cd examples/asolaria-wire
+cargo run --release
+```
+
+It will, with no network or external services:
+1. Generate **200,000** synthetic agent-lane-event records (the clawhip lane-event shape).
+2. Encode each as JSON text and as the `json=0` fixed-width binary; report **B/record** and **ns/record**
+   → expect ~**153.2 / 33.0 B** and the **4.64× size / ~11× encode / decode≈free** figures.
+3. Account the SHA-256 chain (+32 B/rec) → **65.0 B/rec (2.36×)**.
+4. Run the **tamper test**: flip one bit in record #5, re-fold the chain, and confirm the verifier
+   reports **record #5** as the first broken link.
+
+Absolute ns vary by CPU; the **ratios and the tamper-detection** are what to verify. Run `gzip` on the
+two wire forms yourself to confirm the honest nuance in §1.
+
+---
+
+## 7. Honesty self-check
+
+- **Reproducible (re-run them):** 153.2→33.0 B (4.64×), +32 B chain → 65.0 B (2.36×), ~11× encode,
+  decode≈free, and SHA-256 tamper-localization. (200k records; ratios are the portable part.)
+- **Derivable (arithmetic):** 2⁹⁶ ≈ 7.9×10²⁸ handle namespace.
+- **Logical / CANON (do NOT re-run as a count):** the 60-D BEHCS-1024 ceiling `(1024⁶⁰)⁵⁰ ≈ 10⁹⁰³⁰` —
+  address space, not entities. The 520:1 glyph↔descriptor figure is **addressing measured in-fabric**,
+  cited, **not** reproduced by this example.
+- **Architecture / vision (not benchmarked):** clawhip/MCP integration, Lamport ordering,
+  stubbed-rooms-as-RAM paging, every-device-as-surface. Presented as proposed mappings, not deployed
+  facts.
+- **Anti-marketing:** `gzip` closes the raw-size gap; the size win is uncompressed-wire + decode-speed +
+  integrity, never compressibility. FNV-1a-64 is non-cryptographic dedup, not security.

+# claw-analog — как запускать и как это устроено
+
+Минимальный агент поверх того же стека API, что и основной CLI [`claw`](rust/README.md): провайдеры Anthropic / OpenAI‑совместимые / xAI выбираются по модели и переменным окружения (см. [USAGE.md](USAGE.md)).
+
+Дальше в примерах **рабочий каталог** — папка **`claw-code-main\rust`** (внутри клона репозитория). Если приглашение PowerShell уже `…\claw-code-main\rust>`, **не** выполняйте второй раз `cd rust` (иначе будет `rust\rust` и ошибка пути).
+
+## Требования
+
+- Установленный **Rust** и **cargo** (в PATH: обычно `%USERPROFILE%\.cargo\bin` на Windows).
+- Ключ API для выбранного провайдера (например `ANTHROPIC_API_KEY`).
+
+## Сборка и справка
+
+```powershell
+cd D:\path\to\claw-code-main\rust
+cargo build -p claw-analog
+cargo run -p claw-analog -- --help
+```
+
+### Диагностика (`doctor`)
+
+Подкоманда **`claw-analog doctor`** (у неё свой `--help`, отдельно от основного режима):
+
+- **превью конфигурации** — итог после слияния **`.claw-analog.toml`** (путь `<workspace>/.claw-analog.toml` или **`--config`**) и **тех же флагов**, что у основного run: **`--model`**, **`--permission`**, **`--preset`**, **`--output-format`**, **`--stream`**, **`--no-stream`**, **`--no-runtime-enforcer`**, **`--accept-danger-non-interactive`**, плюс **`--profile`** для отображения пути к профилю. Печатаются контракт NDJSON (`schema`, `format_version`), эффективные поля и строки **provenance** (что победило: CLI, TOML или default);
+- статус типовых переменных (**без** значений: только `set` / `unset` и длина строки);
+- поиск workspace вверх от cwd (или **`--manifest-dir`**) и по умолчанию **`cargo check -p claw-analog`** (только компиляция, **не** перезаписывает `target\debug\claw-analog.exe` — иначе на Windows при `cargo run … doctor` часто «Отказано в доступе» при вложенном `cargo build`);
+- **`--release-build`** — **`cargo build --release -p claw-analog`** (бинарь в `target\release\`, не конфликтует с запущенным debug‑exe);
+- **`--no-build`** — пропустить cargo;
+- **`--tcp-ping`** (алиас **`--mock`**) — TCP **`connect`** к хосту:порту из **`ANTHROPIC_BASE_URL`** (или к дефолтному `https://api.anthropic.com`); не проверяет HTTP/TLS и тело ответа.
+
+Примеры (из каталога `…\claw-code-main\rust`):
+
+```powershell
+cargo run -p claw-analog -- doctor
+cargo run -p claw-analog -- doctor --no-build
+cargo run -p claw-analog -- doctor --tcp-ping
+cargo run -p claw-analog -- doctor -w D:\path\to\repo --preset implement
+cargo run -p claw-analog -- doctor --release-build
+```
+
+### Проверка конфигурации без API (`config validate`)
+
+Подкоманда **`claw-analog config validate`**:
+
+- парсит **`.claw-analog.toml`** (по умолчанию `<workspace>/.claw-analog.toml`, переопределение **`--config`**) и выводит краткий **merge preview** (как у `doctor`, но **только TOML + defaults**, без флагов основного run);
+- проверяет **`profile.toml`**: тот же порядок, что у run (`--profile`, поле `profile` в TOML, иначе дефолтный `~/.claw-analog/profile.toml` при наличии файла);
+- **никаких** запросов к LLM и сети API.
+
+**`--strict`** — ошибка (код выхода 1), если файла конфигурации нет или профиль не читается.
+
+```powershell
+cargo run -p claw-analog -- config validate -w D:\path\to\repo
+cargo run -p claw-analog -- config validate --strict -w .
+```
+
+### Дополнение оболочки (`complete`)
+
+Скрипт автодополнения в **stdout** (перенаправьте в файл из документации вашей оболочки):
+
+```powershell
+cargo run -p claw-analog -- complete powershell >> $PROFILE
+# bash:zsh:fish — см. вывод `complete --help`
+```
+
+Доступные значения: **`bash`**, **`zsh`**, **`fish`**, **`powershell`** (алиас **`pwsh`**).
+
+## Основные команды
+
+Одна задача в аргументе (или текст с **stdin**):
+
+```powershell
+# из ...\claw-code-main\rust
+cargo run -p claw-analog -- -w D:\path\to\repo "Кратко опиши структуру rust/crates"
+```
+
+С **живым выводом** (SSE через `stream_message`):
+
+```powershell
+cargo run -p claw-analog -- --stream -w . "Объясни claw-analog в двух предложениях"
+```
+
+Разрешить **запись файлов** в workspace:
+
+```powershell
+cargo run -p claw-analog -- --permission workspace-write -w . "Добавь комментарий в начало crates/claw-analog/Cargo.toml"
+```
+
+Отключить проверку через **`runtime::PermissionEnforcer`** (только своя тюрьма путей; не рекомендуется):
+
+```powershell
+cargo run -p claw-analog -- --no-runtime-enforcer -w . "…"
+```
+
+Полезные лимиты (CLI **перекрывает** значения из `.claw-analog.toml`, см. ниже):
+
+| Флаг | Значение по умолчанию | Назначение |
+|------|------------------------|------------|
+| `--max-read-bytes` | 262144 | Максимум байт для `read_file` / `grep_workspace` / `git_diff` / `git_log` |
+| `--max-turns` | 24 | Максимум раундов «модель → инструменты → модель» |
+| `--max-list-entries` | 500 | Лимит строк `list_dir` |
+| `--grep-max-lines` | 200 | Верхняя граница **суммарных** строк совпадений в `grep_workspace` (в т.ч. по нескольким файлам; в одном файле можно задать меньше через `max_lines`) |
+| `--glob-max-paths` | 2000 | Максимум путей, возвращаемых `glob_workspace` и при расширении `glob` внутри `grep_workspace` |
+| `--glob-max-depth` | 32 | Глубина обхода каталогов для glob (через `walkdir`), без бесконечной рекурсии |
+| `--output-format` | `rich` | `json` — NDJSON на stdout для скриптов и агентов |
+| `--print-tools` | — | Список эффективных инструментов для итоговых `permission` / enforcer, затем выход (**без** промпта и API) |
+| `--lang` | `en` | Подсказка в system: `en` или `ru` (язык ответов; **не** меняет id модели в API) |
+| `--preset` | — | `none` \| `audit` \| `explain` \| `implement` — см. раздел ниже |
+| `--session` | — | Путь к JSON-сессии (относительно `-w`, если не абсолютный): сохранение истории и resume |
+| `--save-session` | — | Дополнительный путь: тот же снимок сессии пишется сюда при каждом сохранении (можно **без** `--session`, чтобы только экспортировать JSON после прогона) |
+| `--profile` | — | TOML с полем `line` (подмешивается в system). Без флага: пробуется `%USERPROFILE%\.claw-analog\profile.toml` (Windows) / `~/.claw-analog/profile.toml` |
+| `--permission` | `read-only` | см. ниже: `read-only`, `workspace-write`, `prompt`, `danger-full-access`, `allow` |
+| `--accept-danger-non-interactive` | — | Разрешить `danger-full-access` / `allow`, когда stdin **не** TTY (CI; осознанный риск). В TOML: `accept_danger_non_interactive = true` |
+
+Конфиг по умолчанию читается из **`<workspace>/.claw-analog.toml`**, если файл существует. Другой путь: **`--config PATH`**. Неизвестные ключи в TOML — ошибка парсинга (строгая схема).
+
+Пример `.claw-analog.toml`:
+
+```toml
+model = "sonnet"
+stream = true
+output_format = "rich"
+permission = "read-only"
+language = "en"
+preset = "audit"
+session = ".claw-analog.session.json"
+profile = "~/.claw-analog/profile.toml"
+no_runtime_enforcer = false
+accept_danger_non_interactive = false
+max_read_bytes = 262144
+max_turns = 24
+max_list_entries = 500
+grep_max_lines = 200
+glob_max_paths = 2000
+glob_max_depth = 32
+# Опционально: RAG (`claw-rag-service`) — см. раздел про RAG ниже
+# rag_base_url = "http://127.0.0.1:8787"
+# rag_timeout_secs = 30
+# rag_top_k_max = 32
+```
+
+**RAG (`retrieve_context`):** если заданы **`RAG_BASE_URL`** (per-env) или непустой **`rag_base_url`** в `.claw-analog.toml`, в набор инструментов добавляется **`retrieve_context`** (семантический поиск по уже проиндексированному воркспейсу). Значение — корень HTTP сервиса, без суффикса `/v1` (запрос идёт на `{base}/v1/query`). Таймаут и верхняя граница **`top_k`** задаются **`rag_timeout_secs`** и **`rag_top_k_max`** (по умолчанию 30 с и 32; «жёсткий» потолок 256). Индексация по-прежнему отдельной командой **`claw-rag-service`**, см. [`docs/rag-web-ui.md`](docs/rag-web-ui.md).
+
+**`permission`** (как у полного `claw`, те же строки в TOML):
+
+| Значение | Инструмент `write_file` | Неинтерактив (stdin не TTY) |
+|----------|-------------------------|------------------------------|
+| `read-only` | нет | OK |
+| `workspace-write` | да (в пределах `-w`) | OK |
+| `prompt` | нет (в этом harness Enforcer не даёт писать без подтверждений) | предупреждение в stderr; для автозаписи используйте `workspace-write` |
+| `danger-full-access`, `allow` | да | **запрещено**, пока не задан `--accept-danger-non-interactive` или `accept_danger_non_interactive = true` в TOML |
+
+**`--stream`** в командной строке включает стриминг; **`--no-stream`** явно выключает (полезно поверх `stream = true` в файле).
+
+**`language`** в TOML: `en` или `ru` (те же значения, что у **`--lang`**); CLI имеет приоритет.
+
+### Сессия (`--session`)
+
+Файл JSON (версия `1`): метаданные `workspace`, `model`, опционально `preset`, массив `messages` в формате API (`role` + `content`). При запуске с существующим файлом история **догружается**, текущий текст запроса (аргумент или stdin) добавляется как **новое** пользовательское сообщение. Состояние сохраняется после каждого полного раунда с инструментами и при завершении без `tool_use`.
+
+**`--save-session`** — тот же формат файла, что и у `--session`: при каждом шаге, где обновлялся бы файл сессии, запись дублируется (если путь совпадает с `--session`, вторая запись не выполняется). Без **`--session`** можно собрать историю одного прогона в JSON для скриптов или последующего **`--session`** без ручной сборки `messages`.
+
+**Риски:** в файле могут оказаться **секреты** (вывод `read_file`, ключи из логов), файл не шифруется; длинная история **дороже** по токенам API. В stderr печатается напоминание при **`--session`** или **`--save-session`**. Несовпадение `workspace` / `model` / `preset` с текущим запуском даёт **предупреждение**, но прогон продолжается.
+
+### Пресеты (`--preset`)
+
+Добавляют краткий абзац к system prompt (аудит / обучение / правки). Набор инструментов по-прежнему задаётся **permission**: для **`implement`**, если ни CLI, ни файл не задали `permission`, по умолчанию подставляется **workspace-write** (чтобы был `write_file`). Явный `permission = "read-only"` в файле или `--permission read-only` в CLI имеет приоритет.
+
+### Профиль (`profile.toml`)
+
+Мини-файл:
+
+```toml
+line = "Короткая подсказка стиля (одна строка в system)."
+```
+
+Ограничения: размер файла не больше **2048** байт; длина строки после trim — не больше **512** символов Unicode (иначе усечение с предупреждением). Содержимое добавляется в system одной строкой: `Learner hint: …`.
+
+## Инструменты (без произвольного shell)
+
+| Имя | Режим | Описание |
+|-----|--------|----------|
+| `read_file` | read-only+ | Чтение UTF‑8 файла под `-w` |
+| `list_dir` | read-only+ | Список каталога (не рекурсивно) |
+| `glob_workspace` | read-only+ | Список **путей файлов** под `-w`: аргументы `pattern` (glob относительно `root`, слэши `/`), опционально `root` (по умолчанию `.`), `max_paths` (урезается лимитом CLI). В шаблоне нельзя `..`. |
+| `grep_workspace` | read-only+ | Та же **литеральная** подстрока по строкам, что и раньше; ровно один из селекторов: `path`, массив `paths` или `glob` (+ опционально `glob_root`). Общий бюджет строк — `max_lines` и `--grep-max-lines`. В нескольких файлах формат строк: `относительный/путь:номер_строки:содержимое`. |
+| `grep_search` | read-only+ | Тот же обработчик, что у `grep_workspace` (совместимость промптов с полным `claw`). |
+| `git_diff` | read-only+ | `git diff` (без цвета) внутри репозитория в `-w`. Опционально `cached` (staged), `rev_range`, `context_lines`, `paths`. Вывод ограничен `--max-read-bytes`. |
+| `git_log` | read-only+ | `git log` (без цвета) внутри репозитория в `-w`. Опционально `max_count` (по умолчанию 20), `rev_range`, `paths`. Вывод ограничен `--max-read-bytes`. |
+| `retrieve_context` | read-only+ | Только если задан **`RAG_BASE_URL`** или **`rag_base_url`** в TOML: HTTP **`POST {base}/v1/query`** к `claw-rag-service`, ответ — пути и сниппеты чанков (лимиты см. выше). |
+| `write_file` | `workspace-write`, `danger-full-access` или `allow` | Запись файла; родительские каталоги создаются при необходимости (`prompt` не даёт записать через Enforcer) |
+
+## Принципы работы
+
+1. **Корень workspace** (`-w`) приводится к каноническому пути; все пути в инструментах **относительные**, без `..` и без абсолютных сегментов.
+2. Перед доступом к файлу проверяется, что реальный путь остаётся **внутри** корня (symlink/`canonicalize`).
+3. **Политика прав** (если не отключена `--no-runtime-enforcer`): те же сущности, что у основного CLI — `PermissionPolicy` + `PermissionEnforcer::check` для инструмента и `check_file_write` для записи.
+4. **Цикл агента**: запрос к провайдеру → если `stop_reason == tool_use`, выполняются вызовы, результаты уходят в историю как `tool_result` → следующий раунд.
+5. **Стриминг**: при `--stream` текст ассистента печатается по мере прихода дельт; история для следующего раунда собирается из SSE так же, как в полном пайплайне (индексы блоков + JSON tool input). Отключить стриминг при настройке из файла можно флагом **`--no-stream`**.
+
+Логи вида `[claw-analog] ...` пишутся в **stderr**. В режиме **rich** ответ модели — обычный текст в **stdout**; в режиме **json** в **stdout** идёт только **NDJSON** (см. ниже).
+
+## Вывод JSON (CI и внешние агенты)
+
+Флаг **`--output-format json`** переключает stdout на **поток строк JSON** (один объект = одна строка). Поля стабильны по смыслу, но набор может расширяться.
+
+Основные `type`:
+
+| `type` | Когда |
+|--------|--------|
+| `run_start` | Старт прогона: **`schema`** (`claw-analog-ndjson`), **`format_version`**, далее `workspace`, `model`, `stream`, `permission`, опционально `preset`, `session`, опционально `session_save`, булево **`rag_enabled`** (есть ли база для `retrieve_context`) |
+| `turn_start` | Начало раунда с моделью (`turn`) |
+| `assistant_text_delta` | Только при `--stream`: фрагмент текста ассистента |
+| `assistant_turn` | Итог раунда: `stop_reason`, `usage`, полный `text`, массив `tool_calls` |
+| `tool_result` | После выполнения инструмента: `name`, `tool_use_id`, `is_error`, `output` (может быть усечён), `truncated`, `output_len_chars` |
+| `run_end` | Успешное завершение (`ok: true`) |
+| `error` | Ошибка (печатается отдельной строкой при падении или пустом промпте) |
+
+Пример (PowerShell): разбор потока построчно удобен **`jq`** или любом JSON‑парсере.
+
+```powershell
+# из ...\claw-code-main\rust
+$env:ANTHROPIC_API_KEY = "sk-ant-..."
+cargo run -p claw-analog -- --output-format json -w . "Summarize rust/README.md" 2>$null | ForEach-Object { $_ | ConvertFrom-Json | Select-Object -ExpandProperty type }
+```
+
+С **`--stream`** в stdout сначала идут события `assistant_text_delta`, затем для того же раунда — одна строка `assistant_turn` с полным собранным `text` (удобно для воспроизводимых логов).
+
+### Ограничения и риски для агентов
+
+- В **`tool_result.output`** большие файлы обрезаются (~32 KiB UTF‑8), поле **`truncated`: true**.
+- **Секреты**: не перенаправляйте stderr сырьём в публичные логи без фильтра; в `output` теоретически может попасть содержимое прочитанных файлов.
+- Контракт для оркестраторов: NDJSON из stdout, диагностика из stderr; код возврата ≠ 0 при ошибке. На первой строке **`run_start`** имеет смысл сверять **`schema`** и **`format_version`**; **`run_start`** также раскрывает путь workspace и модель — учитывайте при шаринге логов.
+
+## Автотесты без реальной сети
+
+Юнит‑тесты и интеграция с локальным **mock-anthropic-service**:
+
+```powershell
+# из ...\claw-code-main\rust
+cargo test -p claw-analog
+```
+
+В **GitHub Actions** отдельный job **`claw-analog (test + clippy -p)`** гоняет `cargo test -p claw-analog` и `cargo clippy -p claw-analog --no-deps` (в дополнение к полному `cargo test` / `clippy` по workspace).
+
+При параллельном запуске тестов переменные окружения Anthropic изолированы **mutex**‑ом только для mock‑сценария; при сбоях можно запустить `cargo test -p claw-analog -- --test-threads=1`.
+
+## Отдельно: `claw-rag-service` (RAG)
+
+Индексация воркспейса и HTTP API живут в **`cargo run -p claw-rag-service`** (`ingest` + `serve`). После `serve` откройте **`http://127.0.0.1:8787/`** — лёгкий UI (stats + поиск). К `claw-analog` подключается через **`RAG_BASE_URL`** / `retrieve_context`. Подробности и env: [`docs/rag-web-ui.md`](docs/rag-web-ui.md).
+
+### Ingest (один или несколько репозиториев)
+
+`ingest` принимает **повторяемый** `--workspace` — это позволяет сделать **cross-repo RAG** (несколько реп в одну БД/коллекцию).
+
+```powershell
+# из ...\claw-code-main\rust
+
+# один workspace
+cargo run -p claw-rag-service -- ingest --workspace "D:\v\kria\s6"
+
+# несколько workspace (cross-repo)
+cargo run -p claw-rag-service -- ingest --workspace "D:\repo1" --workspace "D:\repo2"
+```
+
+В ответах `path` будет вида `repoId:relative/path` (чтобы не было коллизий одинаковых путей между репозиториями).
+
+### Mock embeddings (без ключей / без сети)
+
+Для локальных прогонов/тестов можно включить mock-эмбеддинги:
+
+```powershell
+$env:CLAW_RAG_MOCK_PROVIDERS = "1"
+cargo run -p claw-rag-service -- ingest --workspace "D:\v\kria\s6"
+```
+
+### Qdrant (рекомендуемый локальный вариант) через Docker
+
+Для больших репозиториев лучше поднять локальный Qdrant: это снимает нагрузку с линейного сканирования `SQLite` и ускоряет запросы.
+
+Запуск Qdrant (gRPC на 6334):
+
+```powershell
+docker run --rm -p 6333:6333 -p 6334:6334 -e QDRANT__SERVICE__GRPC_PORT=6334 qdrant/qdrant
+```
+
+#### Qdrant с persist volume (чтобы индекс сохранялся)
+
+Вариант через именованный volume Docker:
+
+```powershell
+docker volume create claw-qdrant-data
+docker run --rm -p 6333:6333 -p 6334:6334 `
+  -e QDRANT__SERVICE__GRPC_PORT=6334 `
+  -v claw-qdrant-data:/qdrant/storage `
+  qdrant/qdrant
+```
+
+Вариант через bind-mount (путь на хосте):
+
+```powershell
+mkdir .claw-qdrant | Out-Null
+docker run --rm -p 6333:6333 -p 6334:6334 `
+  -e QDRANT__SERVICE__GRPC_PORT=6334 `
+  -v "${PWD}/.claw-qdrant:/qdrant/storage" `
+  qdrant/qdrant
+```
+
+Затем включите env и запускайте ingest с фичей `qdrant-index`:
+
+```powershell
+$env:CLAW_RAG_QDRANT_URL = "http://127.0.0.1:6334"
+$env:CLAW_RAG_QDRANT_COLLECTION = "claw_rag_chunks"
+
+# (опционально) без реального API для эмбеддингов
+$env:CLAW_RAG_MOCK_PROVIDERS = "1"
+
+cargo run -p claw-rag-service --features qdrant-index -- ingest --workspace "D:\v\kria\s6"
+```
+
+`ingest` сам создаст коллекцию, если её ещё нет (по размерности эмбеддингов).
+
+### Запуск через Docker (Qdrant + claw-rag-service)
+
+Если хочется поднимать всё одной командой, удобнее использовать `docker compose`.
+
+1) Запуск сервисов:
+
+```powershell
+cd D:\path\to\claw-code-main
+docker compose up --build
+```
+
+Примечание: образ `rag-serve`/`rag-ingest` собирается на достаточно свежем Rust (см. `rust/crates/claw-rag-service/Dockerfile`), потому что `qdrant-client` может требовать более новую версию Rust, чем старые pinned-теги.
+
+Если сборка Docker падает и вы видите строки вроде `transferring context: 21.02GB`, проверьте что:
+
+- вы запускаете compose из корня репозитория (где лежит `docker-compose.yml`)
+- используется `.dockerignore` (уменьшает build-context, особенно если есть `target/` и локальные индексы)
+
+Если сборка падает сразу с `EOF` на шаге `load local bake definitions`, попробуйте:
+
+```powershell
+$env:COMPOSE_BAKE = "0"
+$env:DOCKER_BUILDKIT = "0"
+docker compose up --build
+```
+
+2) Ingest (запускать отдельно, т.к. это batch job). Пример для одного workspace:
+
+```powershell
+docker compose run --rm rag-ingest ingest --workspace "/workspaces/main"
+```
+
+По умолчанию `rag-ingest` пишет индекс в общий volume, так что `rag-serve` сразу увидит чанки.
+
+### Подключение к `claw-analog`
+
+```powershell
+$env:RAG_BASE_URL = "http://127.0.0.1:8787"
+cargo run -p claw-analog -- -w "D:\v\kria\s6" "Найди где реализован ingest в RAG сервисе"
+```
+
+## Auto‑TDD (автопроверки после `write_file`/`edit_file`)
+
+В полном `claw` (и в других потребителях `runtime`) можно включить автозапуск линтера/тестов после успешных write-инструментов через `.claw/settings.json`:
+
+```json
+{
+  "autoTdd": {
+    "enabled": true,
+    "tools": ["write_file", "edit_file"],
+    "commands": [
+      "cd rust && cargo fmt",
+      "cd rust && cargo clippy --workspace --all-targets -- -D warnings",
+      "cd rust && cargo test --workspace"
+    ]
+  }
+}
+```
+
+## Отличия от полного `claw`
+
+- Узкий набор инструментов (нет bash/MCP/плагинов).
+- Проще аудировать и ограничивать по `--permission` и лимитам.
+- Основной продукт по-прежнему `cargo run -p rusty-claude-cli` → бинарь `claw`.
+
+## Дальнейшая разработка
+
+План и чеклист идей (в т.ч. заимствованные из продуктового слоя вроде DeepTutor): [`futute.md`](futute.md) в корне репозитория.

+
+## OVERVIEW
+
+Virtual Cargo workspace (resolver 2, edition 2021) housing 11 crates that compose the `claw` CLI and supporting services.
+
+## STRUCTURE
+
+| Crate | Kind | Purpose |
+|---|---|---|
+| `rusty-claude-cli` | bin (`claw`) | Main CLI binary. Package name ≠ binary name. |
+| `claw-analog` | lib+bin | Alternate entry point; depends on api + runtime only. |
+| `claw-rag-service` | bin | RAG service. Only crate with `[features]` (`qdrant-index`). |
+| `mock-anthropic-service` | lib+bin | Mock Anthropic Messages API. Prints `MOCK_ANTHROPIC_BASE_URL`. Dev-dep for CLI and analog tests. |
+| `runtime` | lib | Core: sessions, permissions, MCP, conversation loop. ~47 modules. |
+| `api` | lib | Provider clients: Anthropic, OpenAI-compat (xAI, OpenAI, DashScope, Ollama). |
+| `tools` | lib | 55-tool surface area. Depends on `commands` (not vice versa). |
+| `commands` | lib | 120+ slash commands. |
+| `plugins` | lib | Plugin manifest and lifecycle. |
+| `telemetry` | lib | Request identity + analytics sinks. |

+Dependency direction: `rusty-claude-cli` → tools/commands/runtime/api/plugins. `tools` → `commands`.
+
+## WHERE TO LOOK
+
+- **Parity testing**: `mock_parity_scenarios.json` at workspace root, loaded via `CARGO_MANIFEST_DIR/../../mock_parity_scenarios.json`. Scripts in `scripts/` (`run_mock_parity_harness.sh`, `run_mock_parity_diff.py`).
+- **CI**: `.github/workflows/rust-ci.yml` (fmt, clippy, test, docs, Windows smoke) and `release.yml` (v* tag builds for linux-x64/macos-arm64/windows-x64).
+- **Committed test fixtures**: `.clawd-agents/`, `.omc/`, `.sandbox-home/` are checked-in harness dotdirs.
+- **Docs**: `PARITY.md`, `TUI-ENHANCEMENT-PLAN.md`, `README.md` alongside this file.
+
+## CONVENTIONS
+
+Workspace lints (all crates opt in via `[lints] workspace = true`):
+- `unsafe_code` = **forbid**. No exceptions.
+- clippy `all` = warn, `pedantic` = allow. Explicitly allowed: `module_name_repetitions`, `missing_panics_doc`, `missing_errors_doc`.
+
+No `rustfmt.toml` or `clippy.toml`. Stock defaults only.
+
+TUI rule: formatting fns take `&mut impl Write`, never stdout directly. Never mix raw ANSI escapes with crossterm.
+
+Library crates don't carry the `claw-` prefix. Binary crates do (except legacy `rusty-claude-cli`).
+
+Workspace version is `0.1.4`, `publish = false`, MIT license.
+
+No rust-toolchain file, no MSRV. CI pins `dtolnay/rust-toolchain@stable`.
+
+## ANTI-PATTERNS
+
+- Don't run `cargo fmt --manifest-path rust/Cargo.toml` from the repo root. Use `../scripts/fmt.sh` instead.
+- Don't add `unsafe` code. The lint is set to `forbid`, not `deny`. You can't `#[allow]` it.
+- Don't create dependencies from `commands` → `tools`. The arrow goes `tools` → `commands`.
+- Don't write TUI output directly to stdout or use raw ANSI escape sequences.
+- Don't add features to crates other than `claw-rag-service` without good reason; the workspace is feature-lean by design.
+
+## COMMANDS
+
+All run from `rust/`:
+
+```sh
+# Format (check only)
+../scripts/fmt.sh --check
+
+# Format (apply)
+../scripts/fmt.sh
+
+# Lint (strict, matches what you should pass before pushing)

+# Build specific binary
+cargo build -p rusty-claude-cli
+cargo build -p claw-analog
+cargo build -p claw-rag-service
+cargo build -p mock-anthropic-service
+```
+
+Note: CI clippy runs without `-D warnings`, so the local check above is stricter than the gate.

 ## Model Aliases

-Short names resolve to the latest model versions:
+Short model aliases resolve to canonical model IDs. Because the router selects a
+provider from the resolved model, an alias also determines which backend and
+credentials are used — choose the alias for the provider you have an API key for.
+Alias resolution is case-insensitive (`OPUS` behaves the same as `opus`). Aliases
+are the bare short names listed below: a prefixed form such as `anthropic/opus`
+is not an alias, and is passed through as-is rather than expanded to
+`claude-opus-4-7`.

-| Alias | Resolves To |
-|-------|------------|
-| `opus` | `claude-opus-4-6` |
-| `sonnet` | `claude-sonnet-4-6` |
-| `haiku` | `claude-haiku-4-5-20251213` |
+| Alias | Resolves To | Provider | Auth env var |
+|-------|-------------|----------|--------------|
+| `opus` | `claude-opus-4-7` | Anthropic | `ANTHROPIC_API_KEY` |
+| `sonnet` | `claude-sonnet-4-6` | Anthropic | `ANTHROPIC_API_KEY` |
+| `haiku` | `claude-haiku-4-5-20251213` | Anthropic | `ANTHROPIC_API_KEY` |
+| `grok`, `grok-3` | `grok-3` | xAI | `XAI_API_KEY` |
+| `grok-mini`, `grok-3-mini` | `grok-3-mini` | xAI | `XAI_API_KEY` |
+| `grok-2` | `grok-2` | xAI | `XAI_API_KEY` |
+| `kimi` | `kimi-k2.5` | DashScope (OpenAI-compatible) | `DASHSCOPE_API_KEY` |
+
+Anthropic aliases track the latest published model versions. xAI models honor
+`XAI_BASE_URL` and Kimi honors `DASHSCOPE_BASE_URL` for base-URL overrides. Alias
+resolution is implemented in `resolve_model_alias`
+([`crates/api/src/providers/mod.rs`](./crates/api/src/providers/mod.rs)); for
+provider-specific request handling see
+[`../docs/MODEL_COMPATIBILITY.md`](../docs/MODEL_COMPATIBILITY.md).

 `claw acp` is a local discoverability surface for editor-first users: it reports the current ACP/Zed status without starting the runtime. As of April 16, 2026, claw-code does **not** ship an ACP/Zed daemon or JSON-RPC entrypoint yet, and `claw acp serve` is only a status alias until the real protocol surface lands. Status queries exit 0 and expose the same machine-readable contract via `--output-format json`; malformed ACP invocations exit 1 with `kind: unsupported_acp_invocation`.
+`--output-format` accepts `text` or `json` in any casing. `CLAW_OUTPUT_FORMAT=json` selects JSON as the default for non-interactive commands, explicit flags override it, repeated flags warn on stderr, and status JSON exposes `format_source`, `format_raw`, and `format_overridden`. Help and doctor output also surface `CLAW_LOG` / `RUST_LOG` as the logging environment knobs.
+`claw version --output-format json` is the provenance probe for automation: it reports full `git_sha`, derived `git_sha_short`, `is_dirty`, `branch`, `commit_date`, `commit_timestamp`, `rustc_version`, runtime `executable_path`, and `binary_provenance`; the text report is available as `human_readable` instead of a duplicate `message` field.
+`status --output-format json` reports loaded project memory files under `workspace.memory_files[]` with each file's `path`, `source` (`claude_md`, `claw_md`, `agents_md`, or scoped/rule sources), `origin`, `scope_path`, `outside_project`, `chars`, and `contributes`; `claw doctor --output-format json` includes a dedicated `memory` check. Root instruction-file priority is `CLAUDE.md`, then `CLAW.md`, then `AGENTS.md`, discovery is bounded to the current git root when present (otherwise cwd only), and all non-duplicate loaded files contribute to the rendered system prompt.
+`claw mcp --output-format json` reports partial MCP config success: valid servers remain in `servers[]` while malformed siblings appear in `invalid_servers[]`, with `total_configured`, `valid_count`, and `invalid_count` split out for automation. `status` mirrors this as `mcp_validation`, and doctor includes an `mcp validation` check.
+`status --output-format json` also reports partial hook config success under `hook_validation`: valid hook entries are retained while malformed or unknown-event siblings appear in `invalid_hooks[]`, with `valid_count`, `invalid_count`, and typed `kind` fields (`invalid_hooks_config` or `unknown_hook_event`) for automation. `doctor --output-format json` includes a `hook validation` check, and `config --output-format json` includes `hook_validation` metadata with degraded status when invalid entries exist.
+Shorthand prompt mode honors the POSIX `--` end-of-flags separator, so `claw -- "-prompt-with-dash"` and unknown dash-prefixed non-flag text stay on the prompt path instead of being treated as CLI options.
+`claw dump-manifests` is self-contained: it emits the Rust resolver inventory for the selected workspace (commands, tools, agents, skills, and bootstrap phases) without requiring an upstream Claude Code TypeScript checkout.

+
+## OVERVIEW
+
+LLM provider client layer: dispatches Anthropic, xAI, OpenAI, DashScope, and Ollama behind two wire protocols (Anthropic Messages native, OpenAI Chat Completions compat).
+
+## WHERE TO LOOK
+
+| Module | What lives here |
+|---|---|
+| `client.rs` | `ProviderClient` enum (facade). `from_model(model)` resolves alias, picks `ProviderKind`, handles OLLAMA_HOST and DashScope qwen-prefix cases. `send_message`/`stream_message`. |
+| `providers/mod.rs` | `Provider` trait (generic, dead_code-allowed, not used for dispatch). `ProviderKind`, `resolve_model_alias`, `ProviderMetadata` (auth_env, base_url_env, default_base_url), `max_tokens_for_model[_with_override]`, capability/diagnostic reporting, `preflight_message_request` validation. |
+| `providers/anthropic.rs` | `AnthropicClient` (re-exported as `ApiClient` at crate root). Dual auth: API key env vs saved OAuth (`AuthSource`, `OAuthTokenSet`, token expiry checks). Base-url resolution. SSE `MessageStream`. Prompt-cache hooks. |
+| `providers/openai_compat.rs` | `OpenAiCompatClient` parameterized by `OpenAiCompatConfig` (presets: `xai()`, `openai()`, `dashscope()`, `OLLAMA_CONFIG`). Heavy translation layer: `build_chat_completion_request`, `translate_message`, `sanitize_tool_message_pairing`, `flatten_tool_result_content`. Model-quirk predicates (`is_reasoning_model`, etc.). Body-size estimation/guards. |
+| `types.rs` | Provider-agnostic wire types: `MessageRequest`, `InputMessage`, `ContentBlock`, `StreamEvent`, `Usage`, `ToolDefinition`, `ToolChoice`. |
+| `sse.rs` | `SseParser`, `parse_frame`. |
+| `http_client.rs` | reqwest builders, `ProxyConfig` from env proxy vars, `TimeoutConfig`. |
+| `error.rs` | `ApiError`. |
+| `prompt_cache.rs` | `PromptCache` + `Stats` (Anthropic-only). |
+| `lib.rs` | Curated `pub use` lists define the public surface. Also re-exports sibling telemetry crate items. |
+
+## CONVENTIONS
+
+- Module-private by default. `lib.rs` `pub use` lists are the sole public API surface.
+- `#[must_use]` on pure constructors.
+- Provider config follows an env-var pair pattern: `*_API_KEY` / `*_BASE_URL`, recorded in `ProviderMetadata`.
+- Leaf files carry targeted `#![allow(clippy::cast_possible_truncation)]` where needed.
+- Dispatch goes through the `ProviderClient` enum, not trait objects. The `Provider` trait exists but is dead-code-allowed.
+- Streams unify into `MessageStream` with `next_event()` yielding `StreamEvent`.
+
+## TESTS
+
+- Four integration test files under `tests/`:
+  - `client_integration` — core client behavior
+  - `openai_compat_integration` — OpenAI-compat translation paths
+  - `provider_client_integration` — `ProviderClient` dispatch
+  - `proxy_integration` — proxy config
+- Tests that touch env vars serialize through a shared `env_lock()` mutex. Don't skip this or you'll get flaky parallel failures.
+- `benches/request_building.rs` is the workspace's only Criterion bench. Targets hot translation functions. This file bulk-opts out of strict lints.

+
+## OVERVIEW
+
+REPL slash-command surface: parsing, spec registry, help rendering, and a handful of in-crate handlers. Single flat `src/lib.rs` (~7k lines). Deps: `plugins`, `runtime`, `serde_json` only. Note: `tools` depends on `commands`, not the reverse.
+
+## lib.rs MAP
+
+| Lines | Landmark |
+|-------------|----------|
+| 16–58 | Registry types: `CommandManifestEntry`, `CommandSource` (Builtin / InternalOnly / FeatureGated), `CommandRegistry`, `SlashCommandSpec`, `SkillSlashDispatch` |
+| 60–1047 | `SLASH_COMMAND_SPECS` static table. 120+ entries (help, status, sandbox, compact, model, permissions, clear, cost, resume, config, mcp, memory, init, diff, version, bughunter, commit, pr, issue, ultraplan, teleport, debug-tool-call, export, session, plugin, agents, skills, doctor, plan, review, tasks, theme, vim, voice, chat, ...) |
+| 1048–1303 | `SlashCommand` enum (~65 variants + `Unknown(String)`), `SlashCommandParseError`, `SlashCommand::parse` (L1218) |
+| 1515–1899 | Per-command arg parsers: `parse_mcp_command`, `parse_plugin_command`, `parse_session_command`, etc. |
+| 1900–2108 | Help/suggestion rendering: `render_slash_command_help*`, `suggest_slash_commands` (Levenshtein), category grouping |
+| 2109–2682 | Result types + handlers: `handle_plugins_slash_command`, `handle_agents/mcp/skills_slash_command(_json)`, skill dispatch/resolve |
+| 3160–5293 | Reporting layer: paired text and `_json` renderers for plugins/agents/skills/mcp reports, skill install/uninstall/create-agent logic, frontmatter parsing, root discovery |
+| 5294 | `handle_slash_command(input, session, compaction)` top dispatch. Only Compact and Help execute here; all other variants return to the REPL caller |
+| 5403–7183 | `mod tests` (~1780 lines) |
+
+## ADDING A SLASH COMMAND
+
+1. **Spec.** Add a `SlashCommandSpec` entry to `SLASH_COMMAND_SPECS`. Set `resume_supported` honestly.
+2. **Enum + parse.** Add a variant to `SlashCommand`. Wire a match arm in `SlashCommand::parse`. If the command takes arguments, add a dedicated `parse_*_command` function in the arg-parser block.
+3. **Handler.** Decide where execution lives:
+   - In-crate (like Compact/Help): handle it inside `handle_slash_command`.
+   - Returned to caller: just return the parsed variant. The REPL layer executes it.
+4. **Help.** Make sure the spec's `summary` and `argument_hint` are set so help rendering and suggestion matching pick it up automatically.
+5. **Tests.** Cover parsing (valid input, bad input, edge cases) in the inline `mod tests`.
+
+## CONVENTIONS
+
+- **Dual renderers.** Every report surface has a text variant and a `_json` variant: `handle_x` / `handle_x_json`, `render_*` / `render_*_json`. Keep them in sync.
+- **Error style.** Handlers return `std::io::Result`. Parse failures use `SlashCommandParseError`.
+- **Manifest registries.** Pattern is `entries: Vec<_Entry>` backed by the static spec table.
+- **Dependency direction.** This crate knows nothing about `tools`. Don't import it.
+- **No execution here.** Almost all commands pass through as parsed data. Only Compact and Help run inside this crate. Respect that boundary.

+/// The block is closed before the failure on purpose: the client only flushes

+/// that frame the partial text would still be sitting in the renderer and the
+/// scenario would not reproduce a turn that streamed text and *then* errored.
+///
+/// The response is cut off in the middle of the failing frame rather than
+/// carrying a complete one. Two things fall out of that, both deliberate.
+///
+/// It is what a provider that dies on the socket actually looks like, and it
+/// keeps the failure in a *later* parser call than the answer text. The whole
+/// response is one `write_all` on the mock's side, so a complete trailing frame
+/// would land in the same read chunk as the deltas — and `SseParser::push`
+/// returns `Err` from inside its frame loop, which discards the events it had
+/// already parsed from that same chunk. The client would then never render the
+/// text at all, and the scenario would be exercising that parser behaviour
+/// instead of the terminal state it is meant to reproduce. A truncated tail
+/// stays in the parser's buffer, so `push` returns the deltas normally and the
+/// failure only surfaces from `finish()`, once the client has consumed every
+/// event ahead of it.
+///
+/// The failure is a frame that does not deserialize — `api::types::StreamEvent`
+/// is `#[serde(tag = "type")]` with no fallback arm, so an unknown frame type or
+/// a truncated payload is an `ApiError::Json`. That is non-retryable, and it is

+# AGENTS.md — plugins crate
+
+## OVERVIEW
+
+Plugin subsystem: how third-party, builtin, and bundled tools/commands/hooks enter the runtime.
+
+## WHERE TO LOOK
+
+- `src/lib.rs` (~3,863 lines): the bulk of the crate. Manifest parsing (`.claude-plugin/plugin.json`), installed-plugin registry, lifecycle model, permission model, install/update management.
+- `src/hooks.rs`: hook event model (`HookEvent`, `HookRunResult`) and `HookRunner` for shell-hook execution. Re-exported from `lib.rs`. **Caution:** the runtime crate has its own `hooks.rs` with a separate `HookRunner` (execution + abort-signal side, around L155). Know which layer you need before editing.
+- `src/test_isolation.rs`: test isolation helpers.
+- `bundled/`: example plugin fixtures. `example-bundled/` and `sample-hooks/` each contain `.claude-plugin/plugin.json` plus `pre.sh`/`post.sh` shell hooks. Treat these as the reference shape when authoring a new plugin.
+
+## CONVENTIONS
+
+**Key public types** (all in `src/lib.rs` unless noted):
+
+- Kinds/definitions: `PluginKind`, `PluginDefinition`, `BuiltinPlugin`, `BundledPlugin`, `ExternalPlugin`.
+- Manifests: `PluginManifest`, `PluginToolManifest`, `PluginToolDefinition`, `PluginToolPermission`, `PluginCommandManifest`.
+- Hooks: `PluginHooks`, `HookEvent`, `HookRunResult` (from `hooks.rs`).
+- Lifecycle/permissions: `PluginLifecycle`, `PluginPermission`.
+- Registry: `InstalledPluginRecord`, `InstalledPluginRegistry`, `RegisteredPlugin`, `PluginRegistry` (+ `Report`, `Summary`, `LoadFailure`).
+- Management: `PluginManager` (+ `Config`), `InstallOutcome`, `UpdateOutcome`.
+- Trait: `Plugin`.
+- Errors: `PluginError`.
+- Entry points: `builtin_plugins()`, `load_plugin_from_directory()`.
+
+**Lifecycle spans two crates.** Manifest parsing and registry live here. Health checks, degraded-mode, and `PluginState` live in `runtime/src/plugin_lifecycle.rs`. Changes to plugin lifecycle logic often touch both.
+
+**Plugin shape.** A plugin directory contains `.claude-plugin/plugin.json` at minimum. Shell hooks (`pre.sh`, `post.sh`) sit alongside. See `bundled/` for working examples.
+
+**Consumers.** `PluginManager` has ~48 references across the workspace. CLI wires plugins via `RuntimePluginStateBuildOutput` in `rusty-claude-cli`. The tools crate exposes plugin tools through `GlobalToolRegistry`.
+
+## NOTES
+
+- Don't confuse the two `HookRunner` implementations. This crate's version handles the event model. The runtime crate's version handles execution and abort signals.
+- `lib.rs` is large. Most searches for plugin behavior start and end there.
+- Bundled plugin fixtures under `bundled/` are used in tests. Breaking their structure breaks CI.
+- Permission model is enforced at install time and checked at runtime. Both paths matter when modifying `PluginPermission`.

+Largest files by line count: config.rs (3894), mcp_stdio.rs (2969), lane_events.rs (2561), worker_boot.rs (2441), session.rs (1961), conversation.rs (1878).
+
+## CONVENTIONS
+
+- One file per module, flat layout. No subdirectories.
+- Most modules are private `mod x` with selective `pub use`. 21 modules are `pub mod`, so consumers use both the re-export and the qualified path.
+- Deps kept minimal: serde, tokio, glob, regex, sha2, walkdir + internal plugins/telemetry. No reqwest, no async-trait. Remote/SSE done by hand.
+- Inline `#[cfg(test)]` tests per file. session.rs has two test modules.
+- `pub(crate) test_env_lock()` mutex in lib.rs serializes env-mutating tests. Use it when touching env vars.
+- trust_resolver.rs is `#[cfg(test)]`-gated yet pub-used: test-only API surface.
+
+## INVARIANTS (do not break)
+
+1. **Compaction pairs**: compact.rs must never split assistant(ToolUse)/ToolResult pairs.
+2. **No side effects on construction**: SessionStore construction must not create `.claw` directories (session_control.rs:1090).
+3. **Workspace containment**: file_ops.rs workspace ops must not escape the workspace root.
+4. **Permission ordering**: a leading read-only permission token must not launder a trailing destructive one (permission_enforcer.rs:450).
+
+## ANTI-PATTERNS
+
+- Don't extend whole-file `#![allow(...)]` blocks. They exist as legacy tolerance in worker_boot.rs, mcp_tool_bridge.rs, lsp_client.rs, stale_branch.rs, stale_base.rs, recovery_recipes.rs, mcp_lifecycle_hardened.rs, session_control.rs. Adding new ones is not acceptable.
+- Don't add reqwest or async-trait as deps. Remote calls go through the manual SSE/proxy layer in remote.rs and sse.rs.
+- Don't create subdirectories under src/. The flat module layout is intentional.
+- Don't bypass `*_in_workspace` variants for file ops when running inside a workspace context. The unchecked versions exist for bootstrap and out-of-workspace scenarios only.
+- Don't add new `pub mod` exports without reason. Prefer private mod + selective `pub use` from lib.rs.

+/// - Any shell metacharacter that could chain, substitute, pipe, or redirect
+///   into a state-changing command rejects the whole line. This blocks
+///   `cat x; rm -rf y`, `cat x | sh`, `$(...)`, backticks, redirects, and
+///   subshells regardless of the leading token.
+/// - Language interpreters (`python`, `node`, `ruby`) and build drivers
+///   (`cargo`, `rustc`) are NOT read-only: they execute arbitrary code, so they
+///   are excluded from the allow-list.
+/// - `git` is allowed only for a known set of non-mutating subcommands.
+/// - `find` is rejected when it carries an action that can execute or delete.
+///
+/// Residual known gaps (documented, not yet closed): `sed`'s `w`/`e` script
+/// commands and `awk`'s `system()` can still mutate — these require quoting or
+/// metacharacters that the checks above usually catch, but a dedicated parser
+/// would be more robust. Tracked as follow-up.

+/// fails and the startup probe rejects the candidate, keeping the plain form.

+/// block mount propagation in user namespaces), the probe fails and the
+/// sandbox stays disabled instead of activating a launcher that always
+/// errors.
