YeonGyu-Kim 47086c1c14 docs(readme): fix cold-start quick-start sequence — set API key before prompt, add claw doctor step
The previous quick start jumped from 'cargo build' to 'claw prompt' without
showing the required auth step or the health-check command. A user following
it linearly would fail because the prompt needs an API key.

Changes:
- Numbered steps: build -> set ANTHROPIC_API_KEY -> claw doctor -> prompt
- Windows note updated to show cargo run form as alternative
- Added explicit NOTE that Claude subscription login is not supported (pre-empts #claw-code FAQ)

Claw Code

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.

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
