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. Use rust/README.md for crate-level details and PARITY.md for the current Rust-port checkpoint.

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

cd rust
cargo build --workspace
./target/debug/claw --help
./target/debug/claw prompt "summarize this repository"

Authenticate with either an API key or the built-in OAuth flow:

export ANTHROPIC_API_KEY="sk-ant-..."
# or
cd rust
./target/debug/claw login

Run the workspace test suite:

cd rust
cargo test --workspace

Documentation map

USAGE.md — quick commands, auth, sessions, config, parity harness
rust/README.md — crate map, CLI surface, features, workspace layout
PARITY.md — parity status for the Rust port
rust/MOCK_PARITY_HARNESS.md — deterministic mock-service harness details
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:
