Claw Code

ultraworkers/claw-code · Usage · Rust workspace · Parity · Roadmap · UltraWorkers Discord

Claw Code is the public Rust implementation of the claw CLI agent harness. The canonical implementation lives in rust/, and the current source of truth for this repository is ultraworkers/claw-code.

Important

Start with USAGE.md for build, auth, CLI, session, and parity-harness workflows. Make claw doctor your first health check after building, use rust/README.md for crate-level details, read PARITY.md for the current Rust-port checkpoint, and see docs/container.md for the container-first workflow.

Current repository shape

• rust/ — canonical Rust workspace and the claw CLI binary
• USAGE.md — task-oriented usage guide for the current product surface
• PARITY.md — Rust-port parity status and migration notes
• ROADMAP.md — active roadmap and cleanup backlog
• PHILOSOPHY.md — project intent and system-design framing
• src/ + tests/ — companion Python/reference workspace and audit helpers; not the primary runtime surface

Quick start

Note

cargo install clawcode will not work — this package is not published on crates.io. Build from source as shown below.

# 1. Clone and build
git clone https://github.com/ultraworkers/claw-code
cd claw-code/rust
cargo build --workspace

# 2. Set your API key (Anthropic API key — not a Claude subscription)
export ANTHROPIC_API_KEY="sk-ant-..."

# 3. Verify everything is wired correctly
./target/debug/claw doctor

# 4. Run a prompt
./target/debug/claw prompt "say hello"

Note

Windows (PowerShell): the binary is claw.exe, not claw. Use .\target\debug\claw.exe or run cargo run -- prompt "say hello" to skip the path lookup.

Windows setup (Git Bash / WSL)

If you are on Windows, the recommended shell is Git Bash (ships with Git for Windows) or WSL. Full sequence:

1. Install Rust — download from https://rustup.rs/ and run the installer. Close and reopen the terminal when it finishes.
2. Open Git Bash — search for "Git Bash" in the Start menu (not PowerShell, not cmd). The prompt shows MINGW64 — this is normal and expected, not a broken install.
3. Verify Rust is on PATH:

   cargo --version
   

   If you see bash: cargo: command not found, run . ~/.cargo/env or restart Git Bash, then retry.
4. Use bash-style paths — in Git Bash, C:\Users\you becomes /c/Users/you:

   cd /c/Users/you/projects
   

5. Clone and build:

   git clone https://github.com/ultraworkers/claw-code
   cd claw-code/rust
   cargo build --workspace
   

6. Run:

   export ANTHROPIC_API_KEY="sk-ant-..."
   ./target/debug/claw prompt "say hello"
   

WSL tip: WSL2 (wsl --install from an admin PowerShell) is the most friction-free Windows path — follow the Linux quick-start steps inside the WSL terminal.

Note

Auth: claw requires an API key (ANTHROPIC_API_KEY, OPENAI_API_KEY, etc.) — Claude subscription login is not a supported auth path.

Run the workspace test suite:

cd rust
cargo test --workspace
