Yeachan-Heo 685d5fef9f Restore slash skill invocation parity after the main merge
The merged command surface still listed /skills but treated every positional argument as unexpected usage text, so slash-based skill invocation regressed. This wires /skills and /agents invocations back through the prompt path, shares skill resolution between the slash/discovery layer and the Skill tool, and teaches skill discovery to see enabled plugin roots plus namespaced plugin skills such as oh-my-claudecode:ralplan.

Constraint: Keep documentation files untouched while restoring the runtime behavior
Rejected: Add a separate skill-invoke tool name | existing Skill tool already covered the loading surface once resolution was fixed
Rejected: Resolve plugin skills only inside the slash handler | would leave the Skill tool and direct invocation path inconsistent
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep slash discovery/help behavior and Skill-tool resolution on the same registry path so plugin and project skills do not drift again
Tested: cargo check; cargo test; direct /skills help overview smoke run
Not-tested: End-to-end live provider execution for a real installed oh-my-claudecode plugin beyond synthetic fixture coverage

Yeachan-Heo 95e1290d23 merge: release/0.1.0 2026-04-01 21:05:52 +00:00
Yeachan-Heo 9415d9c9af Converge the release REPL hardening onto the redesigned CLI
The release branch keeps feat/uiux-redesign as the primary UX surface and only reapplies the hardening changes that still add value there. REPL turns now preserve raw user input, REPL-only unknown slash command guidance can suggest exit shortcuts alongside shared commands, slash completion includes /exit and /quit, and the shared help copy keeps the grouped redesign while making resume guidance a little clearer.

The release-facing README and 0.1.0 draft notes already matched the current release-doc wording, so no extra docs delta was needed in this convergence commit.

Constraint: Keep the redesigned startup/help/status surfaces intact for release/0.1.0
Constraint: Do not reintroduce blanket prompt trimming before runtime submission
Rejected: Port the hardening branch's editor-mode/config path wholesale | it diverged from the redesigned custom line editor and would have regressed the release UX
Rejected: Flatten grouped slash help back into per-command blocks | weaker fit for the redesign's operator-style help surface
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep REPL-only suggestions and completion candidates aligned when adding or removing /vim, /exit, or /quit behavior
Tested: cargo check
Tested: cargo test
Not-tested: Live provider-backed REPL turns and interactive terminal manual QA

Yeachan-Heo a121285a0e Make the CLI feel guided and navigable before release
This redesign pass tightens the first-run and interactive experience
without changing the core execution model. The startup banner is now a
compact readiness summary instead of a large logo block, help output is
layered into quick-start and grouped slash-command sections, status and
permissions views read like operator dashboards, and direct/interactive
error surfaces now point users toward the next useful action.

The REPL also gains cycling slash-command completion so discoverability
improves even before a user has memorized the command set. Shared slash
command metadata now drives grouped help rendering and lightweight
command suggestions, which keeps interactive and non-interactive copy in
sync.

Constraint: Pre-release UX pass had to stay inside the existing Rust workspace with no new dependencies
Constraint: Existing slash command behavior and tests had to remain compatible while improving presentation
Rejected: Introduce a full-screen TUI command palette | too large and risky for this release pass
Rejected: Add trailing-space smart completion for argument-taking commands | conflicted with reliable completion cycling
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep startup hints, grouped slash help, and completion behavior aligned with slash_command_specs as commands evolve
Tested: cargo check
Tested: cargo test
Tested: Manual QA of `claw --help`, piped REPL `/help` `/status` `/permissions` `/session list` `/wat`, direct `/wat`, and interactive Tab cycling in the REPL
Not-tested: Live network-backed conversation turns and long streaming sessions

Yeachan-Heo c0d30934e7 Present Claw Code as the current Rust product
The release-prep docs still framed the workspace as a Rust variant,
which understated the owner's current product position. This update
rewrites the README title and positioning so Claw Code is presented
as the current product surface, while keeping the legal framing clear:
Claude Code inspired, implemented clean-room in Rust, and not a direct
port or copy. The draft 0.1.0 release notes now mirror that language.

Constraint: Docs must reflect the current owner positioning without introducing unsupported product claims
Constraint: Legal framing must stay explicit that this is a clean-room Rust implementation, not a direct port or copy
Rejected: Leave release notes unchanged | would keep product-positioning language inconsistent across release-facing docs
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep future release-facing docs aligned on product naming and clean-room positioning before tagging releases
Tested: Reviewed README and docs/releases/0.1.0.md after edits; verified only intended docs files were staged
Not-tested: cargo check and cargo test (docs-only pass; no code changes)

## 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
- `crates/runtime` — session state, compaction, MCP orchestration, prompt construction
- `crates/tools` — tool manifest definitions and execution framework
- `crates/commands` — slash commands, skills discovery, and config inspection
- `crates/plugins` — plugin model, hook pipeline, and bundled plugins
- `crates/compat-harness` — compatibility layer for upstream editor integration
- `crates/claw-cli` — interactive REPL, markdown rendering, and project bootstrap/init flows
Run the Rust build:
```bash
cd rust
cargo build --release
```
## 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.
@@ -41,6 +62,8 @@ The whole thing was orchestrated end-to-end using [oh-my-codex (OmX)](https://gi
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.**
The Rust port was developed with both [oh-my-codex (OmX)](https://github.com/Yeachan-Heo/oh-my-codex) and [oh-my-opencode (OmO)](https://github.com/code-yeongyu/oh-my-openagent): OmX drove scaffolding, orchestration, and architecture direction, while OmO was used for later implementation acceleration and verification support.

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.
## Built with `oh-my-codex` and `oh-my-opencode`
## Built with `oh-my-codex`
This repository's porting, cleanroom hardening, and verification workflow was AI-assisted with Yeachan Heo's tooling stack, with **oh-my-codex (OmX)** as the primary scaffolding and orchestration layer.
The restructuring and documentation work on this repository was AI-assisted and orchestrated with Yeachan Heo's [oh-my-codex (OmX)](https://github.com/Yeachan-Heo/oh-my-codex), layered on top of Codex.
- [**oh-my-codex (OmX)**](https://github.com/Yeachan-Heo/oh-my-codex) — scaffolding, orchestration, architecture direction, and core porting workflow
- [**oh-my-opencode (OmO)**](https://github.com/code-yeongyu/oh-my-openagent) — implementation acceleration, cleanup, and verification support
- **`$team` mode:** used for coordinated parallel review and architectural feedback
- **`$ralph` mode:** used for persistent execution, verification, and completion discipline
- **Codex-driven workflow:** used to turn the main `src/` tree into a Python-first porting workspace
Key workflow patterns used during the port:
- **`$team` mode:** coordinated parallel review and architectural feedback
- **`$ralph` mode:** persistent execution, verification, and completion discipline
- **Cleanroom passes:** naming/branding cleanup, QA, and release validation across the Rust workspace
- **Manual and live validation:** build, test, manual QA, and real API-path verification before publish

# 🦞 Claw Code — Rust Implementation
# Claw Code
A high-performance Rust rewrite of the Claw Code CLI agent harness. Built for speed, safety, and native tool execution.
Claw Code is a local coding-agent CLI implemented in safe Rust. It is **Claude Code inspired** and developed as a **clean-room implementation**: it aims for a strong local agent experience, but it is **not** a direct port or copy of Claude Code.
## Quick Start
The Rust workspace is the current main product surface. The `claw` binary provides interactive sessions, one-shot prompts, workspace-aware tools, local agent workflows, and plugin-capable operation from a single workspace.
## Current status
- **Version:** `0.1.0`
- **Release stage:** initial public release, source-build distribution
- **Primary implementation:** Rust workspace in this repository
- **Platform focus:** macOS and Linux developer workstations
## Install, build, and run
### Prerequisites
- Rust stable toolchain
- Cargo
- Provider credentials for the model you want to use
### Authentication
Anthropic-compatible models:
```bash
# Build
cd rust/
cargo build --release
export ANTHROPIC_API_KEY="..."
# Optional when using a compatible endpoint
export ANTHROPIC_BASE_URL="https://api.anthropic.com"
```
# Run interactive REPL
Grok models:
```bash
export XAI_API_KEY="..."
# Optional when using a compatible endpoint
export XAI_BASE_URL="https://api.x.ai"
```
OAuth login is also available:
```bash
cargo run --bin claw -- login
```
### Install locally
```bash
cargo install --path crates/claw-cli --locked
```
### Build from source
```bash
cargo build --release -p claw-cli
```
### Run
From the workspace:
```bash
cargo run --bin claw -- --help
cargo run --bin claw --
cargo run --bin claw -- prompt "summarize this workspace"
cargo run --bin claw -- --model sonnet "review the latest changes"
```
From the release build:
```bash
./target/release/claw
# One-shot prompt
./target/release/claw prompt "explain this codebase"
# With specific model
./target/release/claw --model sonnet prompt "fix the bug in main.rs"
./target/release/claw prompt "explain crates/runtime"
```
## Configuration
## Supported capabilities
Set your API credentials:
- Interactive REPL and one-shot prompt execution
- Saved-session inspection and resume flows
- Built-in workspace tools for shell, file read/write/edit, search, web fetch/search, todos, and notebook updates
- Slash commands for status, compaction, config inspection, diff, export, session management, and version reporting
- Local agent and skill discovery with `claw agents` and `claw skills`
- Plugin discovery and management through the CLI and slash-command surfaces
- OAuth login/logout plus model/provider selection from the command line
- Workspace-aware instruction/config loading (`CLAW.md`, config files, permissions, plugin settings)
```bash
export ANTHROPIC_API_KEY="sk-ant-..."
# Or use a proxy
export ANTHROPIC_BASE_URL="https://your-proxy.com"
```
## Current limitations
Or authenticate via OAuth:
- Public distribution is **source-build only** today; this workspace is not set up for crates.io publishing
- GitHub CI verifies `cargo check`, `cargo test`, and release builds, but automated release packaging is not yet present
- Current CI targets Ubuntu and macOS; Windows release readiness is still to be established
- Some live-provider integration coverage is opt-in because it requires external credentials and network access
- The command surface may continue to evolve during the `0.x` series
```bash
claw login
```
## Implementation
## Features
The Rust workspace is the active product implementation. It currently includes these crates:
| Feature | Status |
|---------|--------|
| API + streaming | ✅ |
| OAuth login/logout | ✅ |
| Interactive REPL (rustyline) | ✅ |
| Tool system (bash, read, write, edit, grep, glob) | ✅ |
| Web tools (search, fetch) | ✅ |
| Sub-agent orchestration | ✅ |
| Todo tracking | ✅ |
| Notebook editing | ✅ |
| CLAW.md / project memory | ✅ |
| Config file hierarchy (.claw.json) | ✅ |
| Permission system | ✅ |
| MCP server lifecycle | ✅ |
| Session persistence + resume | ✅ |
| Extended thinking (thinking blocks) | ✅ |
| Cost tracking + usage display | ✅ |
| Git integration | ✅ |
| Markdown terminal rendering (ANSI) | ✅ |
| Model aliases (opus/sonnet/haiku) | ✅ |
| Slash commands (/status, /compact, /clear, etc.) | ✅ |
| Hooks (PreToolUse/PostToolUse) | 🔧 Config only |
| Plugin system | 📋 Planned |
| Skills registry | 📋 Planned |
- `claw-cli` — user-facing binary
- `api` — provider clients and streaming
- `runtime` — sessions, config, permissions, prompts, and runtime loop
- `tools` — built-in tool implementations
- `commands` — slash-command registry and handlers
- `plugins` — plugin discovery, registry, and lifecycle support
- `lsp` — language-server protocol support types and process helpers
- `server` and `compat-harness` — supporting services and compatibility tooling
## Model Aliases
## Roadmap
Short names resolve to the latest model versions:
- Publish packaged release artifacts for public installs
- Add a repeatable release workflow and longer-lived changelog discipline
- Expand platform verification beyond the current CI matrix
- Add more task-focused examples and operator documentation
- Continue tightening feature coverage and UX polish across the Rust implementation
| Alias | Resolves To |
|-------|------------|
| `opus` | `claude-opus-4-6` |
| `sonnet` | `claude-sonnet-4-6` |
| `haiku` | `claude-haiku-4-5-20251213` |

# Claw Code 0.1.0 release notes (draft)
## Summary
Claw Code `0.1.0` is the first public release-prep milestone for the current Rust implementation. Claw Code is Claude Code inspired and built as a clean-room Rust implementation; it is not a direct port or copy. This release centers on a usable local CLI experience: interactive sessions, non-interactive prompts, workspace tools, configuration loading, sessions, plugins, and local agent/skill discovery.
## Highlights
- Initial public `0.1.0` release candidate for Claw Code
- Safe-Rust implementation as the current primary product surface
- `claw` CLI for interactive and one-shot coding-agent workflows
- Built-in workspace tools for shell, file operations, search, web fetch/search, todo tracking, and notebook updates
- Slash-command surface for status, compaction, config inspection, sessions, diff/export, and version info
- Local plugin, agent, and skill discovery/management surfaces
- OAuth login/logout plus model/provider selection
## Install and run
This release is currently intended for source builds:
```bash
cargo install --path crates/claw-cli --locked
# or
cargo build --release -p claw-cli
```
Run:
```bash
claw
claw prompt "summarize this repository"

## Known limitations
- Source-build distribution only; packaged release artifacts are not yet published
- CI currently covers Ubuntu and macOS release builds, checks, and tests
- Windows release readiness is not yet established
- Some integration coverage is opt-in because live provider credentials and network access are required
- Public interfaces may continue to evolve during the `0.x` release line
## Recommended release framing
Position `0.1.0` as the first public release of Claw Code in its current Rust implementation for early adopters who are comfortable building from source. The feature surface is broad enough for real usage, while packaging and release automation can continue to improve in later releases.
## Verification used for this draft
- Workspace version verified from `Cargo.toml`
- `claw` binary/package path verified from `cargo metadata`
- CLI command surface verified from `cargo run --quiet --bin claw -- --help`
- CI coverage verified from `.github/workflows/ci.yml`
