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

[!WARNING] cargo install claw-code installs the wrong thing. The claw-code crate on crates.io is a deprecated stub that places claw-code-deprecated.exe — not claw. Running it only prints "claw-code has been renamed to agent-code". Do not use cargo install claw-code. Either build from source (this repo) or install the upstream binary:

cargo install agent-code   # upstream binary — installs 'agent.exe' (Windows) / 'agent' (Unix), NOT 'agent-code'

This repo (ultraworkers/claw-code) is build-from-source only — follow the steps 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

PowerShell is a supported Windows path. Use whichever shell works for you. The common onboarding issues on Windows are:

Install Rust first — download from https://rustup.rs/ and run the installer. Close and reopen your terminal when it finishes.
Verify Rust is on PATH: If this fails, reopen your terminal or run the PATH setup from the Rust installer output, then retry.

Clone and build (works in PowerShell, Git Bash, or WSL):

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

Run (PowerShell — note .exe and backslash):

$env:ANTHROPIC_API_KEY = "sk-ant-..."
.\target\debug\claw.exe prompt "say hello"

Git Bash / WSL are optional alternatives, not requirements. If you prefer bash-style paths (/c/Users/you/... instead of C:\Users\you\...), Git Bash (ships with Git for Windows) works well. In Git Bash, the MINGW64 prompt is expected and normal — not a broken install.

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

ROADMAP.md — active roadmap and open cleanup work
PHILOSOPHY.md — why the project exists and how it is operated

Ecosystem

Claw Code is built in the open alongside the broader UltraWorkers toolchain:
