auto: save WIP progress from rcc session

The Rust CLI previously hid init behind the REPL slash-command surface and only
created a starter CLAUDE.md. This change adds a direct `init` subcommand and
moves bootstrap behavior into a shared helper so `/init` and `init` create the
same project scaffolding: `.claude/`, `.claude.json`, starter `CLAUDE.md`, and
local-only `.gitignore` entries. The generated guidance now adapts to a small,
explicit set of repository markers so new projects get language/framework-aware
starting instructions without overwriting existing files.

Constraint: Runtime config precedence already treats `.claude.json`, `.claude/settings.json`, and `.claude/settings.local.json` as separate scopes
Constraint: `.claude/sessions/` is used for local session persistence and should not be committed by default
Rejected: Keep init as REPL-only `/init` behavior | would not satisfy the requested direct init command and keeps bootstrap discoverability low
Rejected: Ignore all of `.claude/` | would hide shared project config that the runtime can intentionally load
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep direct `init` and `/init` on the same helper path and keep detection heuristics bounded to explicit repository markers
Tested: cargo fmt --all; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: interactive manual run of `rusty-claude-cli init` against a non-test repository

-This file provides guidance to Claw Code when working with code in this repository.
-
-## Detected stack
-- Languages: Rust.
-- Frameworks: none detected from the supported starter markers.
-
-## Verification
-- Run Rust verification from `rust/`: `cargo fmt`, `cargo clippy --workspace --all-targets -- -D warnings`, `cargo test --workspace`
-- `src/` and `tests/` are both present; update both surfaces together when behavior changes.
-
-## Repository shape
-- `rust/` contains the Rust workspace and active CLI/runtime implementation.
-- `src/` contains source files that should stay consistent with generated guidance and tests.
-- `tests/` contains validation surfaces that should be reviewed alongside code changes.
-
-## Working agreement
-- Prefer small, reviewable changes and keep generated bootstrap files aligned with actual repo workflows.
-- Keep shared defaults in `.claw.json`; reserve `.claw/settings.local.json` for machine-local overrides.
-- Do not overwrite existing `CLAW.md` content automatically; update it intentionally when repo workflows change.

-# PARITY GAP ANALYSIS
-
-Scope: read-only comparison between the original TypeScript source at `/home/bellman/Workspace/claw-code/src/` and the Rust port under `rust/crates/`.
-
-Method: compared feature surfaces, registries, entrypoints, and runtime plumbing only. No TypeScript source was copied.
-
-## Executive summary
-
-The Rust port has a good foundation for:
-- Anthropic API/OAuth basics
-- local conversation/session state
-- a core tool loop
-- MCP stdio/bootstrap support
-- CLAW.md discovery
-- a small but usable built-in tool set
-
-It is **not feature-parity** with the TypeScript CLI.
-
-Largest gaps:
-- **plugins** are effectively absent in Rust
-- **hooks** are parsed but not executed in Rust
-- **CLI breadth** is much narrower in Rust
-- **skills** are local-file only in Rust, without the TS registry/bundled pipeline
-- **assistant orchestration** lacks TS hook-aware orchestration and remote/structured transports
-- **services** beyond core API/OAuth/MCP are mostly missing in Rust

-## tools/
-
-### TS exists
-Evidence:
-- `src/tools/` contains broad tool families including `AgentTool`, `AskUserQuestionTool`, `BashTool`, `ConfigTool`, `FileReadTool`, `FileWriteTool`, `GlobTool`, `GrepTool`, `LSPTool`, `ListMcpResourcesTool`, `MCPTool`, `McpAuthTool`, `ReadMcpResourceTool`, `RemoteTriggerTool`, `ScheduleCronTool`, `SkillTool`, `Task*`, `Team*`, `TodoWriteTool`, `ToolSearchTool`, `WebFetchTool`, `WebSearchTool`.
-- Tool execution/orchestration is split across `src/services/tools/StreamingToolExecutor.ts`, `src/services/tools/toolExecution.ts`, `src/services/tools/toolHooks.ts`, and `src/services/tools/toolOrchestration.ts`.
-
-### Rust exists
-Evidence:
-- Tool registry is centralized in `rust/crates/tools/src/lib.rs` via `mvp_tool_specs()`.
-- Current built-ins include shell/file/search/web/todo/skill/agent/config/notebook/repl/powershell primitives.
-- Runtime execution is wired through `rust/crates/tools/src/lib.rs` and `rust/crates/runtime/src/conversation.rs`.
-
-### Missing or broken in Rust
-- No Rust equivalents for major TS tools such as `AskUserQuestionTool`, `LSPTool`, `ListMcpResourcesTool`, `MCPTool`, `McpAuthTool`, `ReadMcpResourceTool`, `RemoteTriggerTool`, `ScheduleCronTool`, `Task*`, `Team*`, and several workflow/system tools.
-- Rust tool surface is still explicitly an MVP registry, not a parity registry.
-- Rust lacks TS’s layered tool orchestration split.
-
-**Status:** partial core only.

-## hooks/
-
-### TS exists
-Evidence:
-- Hook command surface under `src/commands/hooks/`.
-- Runtime hook machinery in `src/services/tools/toolHooks.ts` and `src/services/tools/toolExecution.ts`.
-- TS supports `PreToolUse`, `PostToolUse`, and broader hook-driven behaviors configured through settings and documented in `src/skills/bundled/updateConfig.ts`.
-
-### Rust exists
-Evidence:
-- Hook config is parsed and merged in `rust/crates/runtime/src/config.rs`.
-- Hook config can be inspected via Rust config reporting in `rust/crates/commands/src/lib.rs` and `rust/crates/claw-cli/src/main.rs`.
-- Prompt guidance mentions hooks in `rust/crates/runtime/src/prompt.rs`.
-
-### Missing or broken in Rust
-- No actual hook execution pipeline in `rust/crates/runtime/src/conversation.rs`.
-- No PreToolUse/PostToolUse mutation/deny/rewrite/result-hook behavior.
-- No Rust `/hooks` parity command.
-
-**Status:** config-only; runtime behavior missing.

-- Repo-wide Rust references to plugins are effectively absent beyond text/help mentions.
-
-### Missing or broken in Rust
-- No plugin loader.
-- No marketplace install/update/enable/disable flow.
-- No `/plugin` or `/reload-plugins` parity.
-- No plugin-provided hook/tool/command/MCP extension path.

-- Skills command surface under `src/commands/skills/`.
-
-### Rust exists
-Evidence:
-- `Skill` tool in `rust/crates/tools/src/lib.rs` resolves and reads local `SKILL.md` files.
-- CLAW.md discovery is implemented in `rust/crates/runtime/src/prompt.rs`.
-- Rust supports `/memory` and `/init` via `rust/crates/commands/src/lib.rs` and `rust/crates/claw-cli/src/main.rs`.
-
-### Missing or broken in Rust
-- No bundled skill registry equivalent.
-- No `/skills` command.
-- No MCP skill-builder pipeline.
-- No TS-style live skill discovery/reload/change handling.
-- No comparable session-memory / team-memory integration around skills.
-
-**Status:** basic local skill loading only.

-- Structured/remote transport stack in `src/cli/structuredIO.ts`, `src/cli/remoteIO.ts`, and `src/cli/transports/*`.
-- CLI handler split in `src/cli/handlers/*`.
-
-### Rust exists
-Evidence:
-- Shared slash command registry in `rust/crates/commands/src/lib.rs`.
-- Rust slash commands currently cover `help`, `status`, `compact`, `model`, `permissions`, `clear`, `cost`, `resume`, `config`, `memory`, `init`, `diff`, `version`, `export`, `session`.
-- Main CLI/repl/prompt handling lives in `rust/crates/claw-cli/src/main.rs`.

-### Missing or broken in Rust
-- Missing major TS command families: `/agents`, `/hooks`, `/mcp`, `/plugin`, `/skills`, `/plan`, `/review`, `/tasks`, and many others.
-- No Rust equivalent to TS structured IO / remote transport layers.
-- No TS-style handler decomposition for auth/plugins/MCP/agents.
-- JSON prompt mode is improved on this branch, but still not clean transport parity: empirical verification shows tool-capable JSON output can emit human-readable tool-result lines before the final JSON object.
-

-
-**Status:** strong core loop, missing orchestration layers.

-## services/ (API client, auth, models, MCP)
-
-### TS exists
-Evidence:
-- API services under `src/services/api/*`.
-- OAuth services under `src/services/oauth/*`.
-- MCP services under `src/services/mcp/*`.
-- Additional service layers for analytics, prompt suggestion, session memory, plugin operations, settings sync, policy limits, team memory sync, notifier, voice, and more under `src/services/*`.

-- Usage accounting in `rust/crates/runtime/src/usage.rs`.
-- Remote upstream-proxy support in `rust/crates/runtime/src/remote.rs`.
-
-### Missing or broken in Rust
-- Most TS service ecosystem beyond core messaging/auth/MCP is absent.
-- No TS-equivalent plugin service layer.
-- No TS-equivalent analytics/settings-sync/policy-limit/team-memory subsystems.
-- No TS-style MCP connection-manager/UI layer.
-- Model/provider ergonomics remain thinner than TS.
-
-**Status:** core foundation exists; broader service ecosystem missing.
-
----
-
-## Critical bug status in this worktree
-
-### Fixed
-- **Prompt mode tools enabled**
-  - `rust/crates/claw-cli/src/main.rs` now constructs prompt mode with `LiveCli::new(model, true, ...)`.
-- **Default permission mode = DangerFullAccess**
-  - Runtime default now resolves to `DangerFullAccess` in `rust/crates/claw-cli/src/main.rs`.
-  - Clap default also uses `DangerFullAccess` in `rust/crates/claw-cli/src/args.rs`.
-  - Init template writes `dontAsk` in `rust/crates/claw-cli/src/init.rs`.
-- **Streaming `{}` tool-input prefix bug**
-  - `rust/crates/claw-cli/src/main.rs` now strips the initial empty object only for streaming tool input, while preserving legitimate `{}` in non-stream responses.
-- **Unlimited max_iterations**
-  - Verified at `rust/crates/runtime/src/conversation.rs` with `usize::MAX`.
-
-### Remaining notable parity issue
-- **JSON prompt output cleanliness**
-  - Tool-capable JSON mode now loops, but empirical verification still shows pre-JSON human-readable tool-result output when tools fire.

-## Rust Port
-
-The Rust workspace under `rust/` is the current systems-language port of the project.
-
-It currently includes:
-
-- `crates/api-client` — API client with provider abstraction, OAuth, and streaming support

 ## Backstory
 
-At 4 AM on March 31, 2026, I woke up to my phone blowing up with notifications. The Claw Code source had been exposed, and the entire dev community was in a frenzy. My girlfriend in Korea was genuinely worried I might face legal action from the original authors just for having the code on my machine — so I did what any engineer would do under pressure: I sat down, ported the core features to Python from scratch, and pushed it before the sun came up.

My girlfriend in Korea was genuinely worried I might face legal action from Anthropic just for having the code on my machine — so I did what any engineer would do under pressure: I sat down, ported the core features to Python from scratch, and pushed it before the sun came up.
 
 The whole thing was orchestrated end-to-end using [oh-my-codex (OmX)](https://github.com/Yeachan-Heo/oh-my-codex) by [@bellman_ych](https://x.com/bellman_ych) — a workflow layer built on top of OpenAI's Codex ([@OpenAIDevs](https://x.com/OpenAIDevs)). I used `$team` mode for parallel code review and `$ralph` mode for persistent execution loops with architect-level verification. The entire porting session — from reading the original harness structure to producing a working Python tree with tests — was driven through OmX orchestration.
 
-The result is a clean-room Python rewrite that captures the architectural patterns of Claw Code's agent harness without copying any proprietary source. I'm now actively collaborating with [@bellman_ych](https://x.com/bellman_ych) — the creator of OmX himself — to push this further. The basic Python foundation is already in place and functional, but we're just getting started. **Stay tuned — a much more capable version is on the way.**

 I've been deeply interested in **harness engineering** — studying how agent systems wire tools, orchestrate tasks, and manage runtime context. This isn't a sudden thing. The Wall Street Journal featured my work earlier this month, documenting how I've been one of the most active power users exploring these systems:
 
-> AI startup worker Sigrid Jin, who attended the Seoul dinner, single-handedly used 25 billion of Claw Code tokens last year. At the time, usage limits were looser, allowing early enthusiasts to reach tens of billions of tokens at a very low cost.

 The port now mirrors the archived root-entry file surface, top-level subsystem names, and command/tool inventories much more closely than before. However, it is **not yet** a full runtime-equivalent replacement for the original TypeScript system; the Python tree still contains fewer executable runtime slices than the archived source.

-# Contributing
-
-Thanks for contributing to Claw Code.
-
-## Development setup
-
-- Install the stable Rust toolchain.
-- Work from the repository root in this Rust workspace. If you started from the parent repo root, `cd rust/` first.
-
-## Build
-
-```bash
-cargo build
-cargo build --release
-```
-
-## Test and verify
-
-Run the full Rust verification set before you open a pull request:
-
-```bash
-cargo fmt --all --check
-cargo clippy --workspace --all-targets -- -D warnings
-cargo check --workspace
-cargo test --workspace
-```
-
-If you change behavior, add or update the relevant tests in the same pull request.
-
-## Code style
-
-- Follow the existing patterns in the touched crate instead of introducing a new style.
-- Format code with `rustfmt`.
-- Keep `clippy` clean for the workspace targets you changed.
-- Prefer focused diffs over drive-by refactors.
-
-## Pull requests
-
-- Branch from `main`.
-- Keep each pull request scoped to one clear change.
-- Explain the motivation, the implementation summary, and the verification you ran.
-- Make sure local checks pass before requesting review.
-- If review feedback changes behavior, rerun the relevant verification commands.

-### Crate Responsibilities
+## Prerequisites
 
-- **api** — HTTP client, SSE stream parser, request/response types, auth (API key + OAuth bearer)
-- **commands** — Slash command definitions and help text generation
-- **compat-harness** — Extracts tool/prompt manifests from upstream TS source
-- **runtime** — `ConversationRuntime` agentic loop, `ConfigLoader` hierarchy, `Session` persistence, permission policy, MCP client, system prompt assembly, usage tracking
-- **claw-cli** — REPL, one-shot prompt, streaming display, tool call rendering, CLI argument parsing
-- **tools** — Tool specs + execution: Bash, ReadFile, WriteFile, EditFile, GlobSearch, GrepSearch, WebSearch, WebFetch, Agent, TodoWrite, NotebookEdit, Skill, ToolSearch, REPL runtimes
+- Rust toolchain installed (`rustup`, stable toolchain)
+- Network access and Anthropic credentials for live prompt/REPL usage
 
-## Stats
+## Build
 
-- **~20K lines** of Rust
-- **6 crates** in workspace
-- **Binary name:** `claw`
-- **Default model:** `claude-opus-4-6`
-- **Default permissions:** `danger-full-access`
+From the repository root:
 
-## License
+```bash
+cd rust
+cargo build --release -p rusty-claude-cli
+```
 
-See repository root.
+The optimized binary will be written to:
+
+```bash
+./target/release/rusty-claude-cli
+```
+
+## Test
+
+Run the verified workspace test suite used for release-readiness:
+
+```bash
+cd rust
+cargo test --workspace --exclude compat-harness
+```
+
+## Quick start
+
+### Show help
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli -- --help
+```
+
+### Print version
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli -- --version
+```
+
+### Login with OAuth
+
+Configure `settings.json` with an `oauth` block containing `clientId`, `authorizeUrl`, `tokenUrl`, optional `callbackPort`, and optional `scopes`, then run:
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli -- login
+```
+
+This opens the browser, listens on the configured localhost callback, exchanges the auth code for tokens, and stores OAuth credentials in `~/.claude/credentials.json` (or `$CLAUDE_CONFIG_HOME/credentials.json`).
+
+### Logout
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli -- logout
+```
+
+This removes only the stored OAuth credentials and preserves unrelated JSON fields in `credentials.json`.
+
+## Usage examples
+
+### 1) Prompt mode
+
+Send one prompt, stream the answer, then exit:
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli -- prompt "Summarize the architecture of this repository"
+```
+
+Use a specific model:
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli -- --model claude-sonnet-4-20250514 prompt "List the key crates in this workspace"
+```
+
+Restrict enabled tools in an interactive session:
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli -- --allowedTools read,glob
+```
+
+Bootstrap Claude project files for the current repo:
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli -- init
+```
+
+### 2) REPL mode
+
+Start the interactive shell:
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli --
+```
+
+Inside the REPL, useful commands include:
+
+```text
+/help
+/status
+/model claude-sonnet-4-20250514
+/permissions workspace-write
+/cost
+/compact
+/memory
+/config
+/init
+/diff
+/version
+/export notes.txt
+/session list
+/exit
+```
+
+### 3) Resume an existing session
+
+Inspect or maintain a saved session file without entering the REPL:
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli -- --resume session.json /status /compact /cost
+```
+
+You can also inspect memory/config state for a restored session:
+
+```bash
+cd rust
+cargo run -p rusty-claude-cli -- --resume session.json /memory /config
+```
+
+## Available commands
+
+### Top-level CLI commands
+
+- `prompt <text...>` — run one prompt non-interactively
+- `--resume <session.json> [/commands...]` — inspect or maintain a saved session
+- `dump-manifests` — print extracted upstream manifest counts
+- `bootstrap-plan` — print the current bootstrap skeleton
+- `system-prompt [--cwd PATH] [--date YYYY-MM-DD]` — render the synthesized system prompt
+- `--help` / `-h` — show CLI help
+- `--version` / `-V` — print the CLI version and build info locally (no API call)
+- `--output-format text|json` — choose non-interactive prompt output rendering
+- `--allowedTools <tool[,tool...]>` — restrict enabled tools for interactive sessions and prompt-mode tool use
+
+### Interactive slash commands
+
+- `/help` — show command help
+- `/status` — show current session status
+- `/compact` — compact local session history
+- `/model [model]` — inspect or switch the active model
+- `/permissions [read-only|workspace-write|danger-full-access]` — inspect or switch permissions
+- `/clear [--confirm]` — clear the current local session
+- `/cost` — show token usage totals
+- `/resume <session-path>` — load a saved session into the REPL
+- `/config [env|hooks|model]` — inspect discovered Claude config
+- `/memory` — inspect loaded instruction memory files
+- `/init` — bootstrap `.claude.json`, `.claude/`, `CLAUDE.md`, and local ignore rules
+- `/diff` — show the current git diff for the workspace
+- `/version` — print version and build metadata locally
+- `/export [file]` — export the current conversation transcript
+- `/session [list|switch <session-id>]` — inspect or switch managed local sessions
+- `/exit` — leave the REPL
+
+## Environment variables
+
+### Anthropic/API
+
+- `ANTHROPIC_API_KEY` — highest-precedence API credential
+- `ANTHROPIC_AUTH_TOKEN` — bearer-token override used when no API key is set
+- Persisted OAuth credentials in `~/.claude/credentials.json` — used when neither env var is set
+- `ANTHROPIC_BASE_URL` — override the Anthropic API base URL
+- `ANTHROPIC_MODEL` — default model used by selected live integration tests
+
+### CLI/runtime
+
+- `RUSTY_CLAUDE_PERMISSION_MODE` — default REPL permission mode (`read-only`, `workspace-write`, or `danger-full-access`)
+- `CLAUDE_CONFIG_HOME` — override Claude config discovery root
+- `CLAUDE_CODE_REMOTE` — enable remote-session bootstrap handling when supported
+- `CLAUDE_CODE_REMOTE_SESSION_ID` — remote session identifier when using remote mode
+- `CLAUDE_CODE_UPSTREAM` — override the upstream TS source path for compat-harness extraction
+- `CLAWD_WEB_SEARCH_BASE_URL` — override the built-in web search service endpoint used by tooling
+
+## Notes
+
+- `compat-harness` exists to compare the Rust port against the upstream TypeScript codebase and is intentionally excluded from the requested release test run.
+- The CLI currently focuses on a practical integrated workflow: prompt execution, REPL operation, session inspection/resume, config discovery, and tool/runtime plumbing.
