> Start with [`USAGE.md`](./USAGE.md) for build, auth, CLI, session, and parity-harness workflows. Make `claw doctor` your first health check after building, use [`rust/README.md`](./rust/README.md) for crate-level details, read [`PARITY.md`](./PARITY.md) for the current Rust-port checkpoint, and see [`docs/container.md`](./docs/container.md) for the container-first workflow.
> **ACP / Zed status:** `claw-code` does not ship an ACP/Zed daemon entrypoint yet. Run `claw acp` (or `claw --acp`) for the current status instead of guessing from source layout; `claw acp serve` is currently a discoverability alias only, and real ACP support remains tracked separately in `ROADMAP.md`.
> **`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:
> **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.
**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.
After running `cargo build --workspace`, the `claw` binary is built but **not** automatically installed to your system. Here's where to find it and how to verify the build succeeded.
### Binary location
After `cargo build --workspace` in `claw-code/rust/`:
**Debug build (default, faster compile):**
- **macOS/Linux:** `rust/target/debug/claw`
- **Windows:** `rust/target/debug/claw.exe`
**Release build (optimized, slower compile):**
- **macOS/Linux:** `rust/target/release/claw`
- **Windows:** `rust/target/release/claw.exe`
If you ran `cargo build` without `--release`, the binary is in the `debug/` folder.
### Verify the build succeeded
Test the binary directly using its path:
```bash
# macOS/Linux (debug build)
./rust/target/debug/claw --help
./rust/target/debug/claw doctor
# Windows PowerShell (debug build)
.\rust\target\debug\claw.exe --help
.\rust\target\debug\claw.exe doctor
```
If these commands succeed, the build is working. `claw doctor` is your first health check — it validates your API key, model access, and tool configuration.
### Optional: Add to PATH
If you want to run `claw` from any directory without the full path, choose one of these approaches:
Build and install to Cargo's default location (`~/.cargo/bin/`, which is usually on PATH):
```bash
# From the claw-code/rust/ directory
cargo install --path . --force
# Then from anywhere
claw --help
```
**Option 3: Update shell profile (bash/zsh)**
Add this line to `~/.bashrc` or `~/.zshrc`:
```bash
export PATH="$(pwd)/rust/target/debug:$PATH"
```
Reload your shell:
```bash
source ~/.bashrc # or source ~/.zshrc
claw --help
```
### Troubleshooting
- **"command not found: claw"** — The binary is in `rust/target/debug/claw`, but it's not on your PATH. Use the full path `./rust/target/debug/claw` or symlink/install as above.
- **"permission denied"** — On macOS/Linux, you may need `chmod +x rust/target/debug/claw` if the executable bit isn't set (rare).
- **Debug vs. release** — If the build is slow, you're in debug mode (default). Add `--release` to `cargo build` for faster runtime, but the build itself will take 5–10 minutes.
