Claw Code

Claw Code is an open source Claude Code with Rust implementation. It is a local coding-agent CLI that provides an interactive agent shell, one-shot prompts, workspace-aware tools, plugin support, and resumeable sessions.

Start here

1. Install Rust stable and Cargo.
2. Set up credentials for the model provider you want to use.
3. Run the CLI from the rust/ workspace.

First run

From the repository root:

cd rust

Build the CLI:

cargo build --release -p claw-cli

Start the interactive shell:

cargo run --bin claw -- --help
cargo run --bin claw --

Run a single prompt:

cargo run --bin claw -- prompt "summarize this workspace"

Install it locally if you want the binary on your PATH:

cargo install --path crates/claw-cli --locked

Authentication

Use whichever provider you have access to.

Anthropic-compatible models:

export ANTHROPIC_API_KEY="..."
export ANTHROPIC_BASE_URL="https://api.anthropic.com"

Grok models:

export XAI_API_KEY="..."
export XAI_BASE_URL="https://api.x.ai"

You can also authenticate through the CLI:

cargo run --bin claw -- login

Common commands

cargo run --bin claw -- prompt "review the latest changes"
cargo run --bin claw -- init
cargo run --bin claw -- logout
cargo run --bin claw -- --resume session.json /status

Run claw --help for the full command list, including agents, skills, system-prompt output, and slash-command flows.

Repository layout

.
├── rust/            # Active Rust workspace and CLI/runtime implementation
├── src/             # Python porting workspace and support code
├── tests/           # Python verification
├── CLAW.md          # Repo-specific working notes
└── README.md        # This guide

Development

Use the Rust workspace for local verification:

cd rust
cargo fmt
cargo clippy --workspace --all-targets -- -D warnings
cargo test --workspace

If you change the Python workspace in src/, keep the matching tests in tests/ updated too.

Notes

• This repo is an open source Claude Code-style Rust implementation, not the original Claude Code source.
• CLAW.md contains the workflow guidance for contributors working in this tree.
