## Problem `runtime::config::tests::validates_unknown_top_level_keys_with_line_and_field_name` intermittently fails during `cargo test --workspace` (witnessed during #147 and #148 workspace runs) but passes deterministically in isolation. Example failure from workspace run: test result: FAILED. 464 passed; 1 failed ## Root cause `runtime/src/config.rs::tests::temp_dir()` used nanosecond timestamp alone for namespace isolation: std::env::temp_dir().join(format!("runtime-config-{nanos}")) Under parallel test execution on fast machines with coarse clock resolution, two tests start within the same nanosecond bucket and collide on the same path. One test's `fs::remove_dir_all(root)` then races another's in-flight `fs::create_dir_all()`. Other crates already solved this pattern: - plugins::tests::temp_dir(label) — label-parameterized - runtime::git_context::tests::temp_dir(label) — label-parameterized runtime/src/config.rs was missed. ## Fix Added process id + monotonically-incrementing atomic counter to the namespace, making every callsite provably unique regardless of clock resolution or scheduling: static COUNTER: AtomicU64 = AtomicU64::new(0); let pid = std::process::id(); let seq = COUNTER.fetch_add(1, Ordering::Relaxed); std::env::temp_dir().join(format!("runtime-config-{pid}-{nanos}-{seq}")) Chose counter+pid over the label-parameterized pattern to avoid touching all 20 callsites in the same commit (mechanical noise with no added safety — counter alone is sufficient). ## Verification Before: one failure per workspace run (config test flake). After: 5 consecutive `cargo test --workspace` runs — zero config test failures. Only pre-existing `resume_latest` flake remains (orthogonal, unrelated to this change). for i in 1 2 3 4 5; do cargo test --workspace; done # All 5 runs: config tests green. Only resume_latest flake appears. cargo test -p runtime # 465 passed; 0 failed ## ROADMAP.md Added Pinpoint #149 documenting the gap, root cause, and fix. Closes ROADMAP #149.

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.mdfor build, auth, CLI, session, and parity-harness workflows. Makeclaw doctoryour first health check after building, userust/README.mdfor crate-level details, readPARITY.mdfor the current Rust-port checkpoint, and seedocs/container.mdfor the container-first workflow.ACP / Zed status:
claw-codedoes not ship an ACP/Zed daemon entrypoint yet. Runclaw acp(orclaw --acp) for the current status instead of guessing from source layout;claw acp serveis currently a discoverability alias only, and real ACP support remains tracked separately inROADMAP.md.

Quick start
Note
[!WARNING]
cargo install claw-codeinstalls the wrong thing. Theclaw-codecrate on crates.io is a deprecated stub that placesclaw-code-deprecated.exe— notclaw. Running it only prints"claw-code has been renamed to agent-code". Do not usecargo 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, notclaw. Use.\target\debug\claw.exeor runcargo 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.cargo --version - 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
.exeand 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
