Dogfooded 2026-04-18 on main HEAD 6580903 from /tmp/cdZ.
.claw.json with {"model":"haiku"} produces:
claw status → model: 'claude-opus-4-6' (DEFAULT_MODEL, config ignored)
claw doctor → 'Resolved model haiku' (raw alias, label lies)
turn dispatch → claude-haiku-4-5-20251213 (actually-resolved canonical)
ANTHROPIC_MODEL=sonnet → status still says claude-opus-4-6
FOUR separate understandings of 'active model':
1. config file (alias as written)
2. doctor (alias mislabeled as 'Resolved')
3. status (hardcoded DEFAULT_MODEL ignoring config entirely)
4. turn dispatch (canonical, alias-resolved, what turns actually use)
Trace:
main.rs:59 DEFAULT_MODEL const = claude-opus-4-6
main.rs:400 parse_args starts model = DEFAULT_MODEL
main.rs:753 Status dispatch: model.to_string() — never calls
resolve_repl_model, never reads config or env
main.rs:1125 resolve_repl_model: source of truth for actual
model, consults ANTHROPIC_MODEL env + config + alias table.
Called from Prompt and Repl dispatch. NOT from Status.
main.rs:1701 check_config_health: 'Resolved model {model}'
where model is raw configured string, not resolved.
Label says Resolved, value is pre-resolution alias.
Orchestration hazard: a claw picks tool strategy based on
status.model assuming it reflects what turns will use. Status
lies: always reports DEFAULT_MODEL unless --model flag was
passed. Config and env var completely ignored by status.
Fix shape (~30 lines):
- call resolve_repl_model from print_status_snapshot
- add effective_model field to status JSON (or rename/enrich)
- fix doctor 'Resolved model' label (either rename to 'Configured'
or actually alias-resolve before emitting)
- honor ANTHROPIC_MODEL env in status
- regression tests per model source with cross-surface equality

Claw Code
ultraworkers/claw-code · Usage · Rust workspace · Parity · Roadmap · UltraWorkers Discord
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
