Previously `claw status` hard-failed on any config parse error, emitting
a bare error string and exiting 1. This took down the entire health
surface for a single malformed MCP entry, even though workspace, git,
model, permission, and sandbox state could all be reported independently.
`claw doctor` already degraded gracefully on the exact same input.
This commit matches `claw status` to that contract.
Changes:
- Add `StatusContext::config_load_error: Option<String>` to capture parse
errors without aborting.
- Rewrite `status_context()` to match on `ConfigLoader::load()`: on Err,
fall back to default `SandboxConfig` for sandbox resolution and record
the parse error, then continue populating workspace/git/memory fields.
- JSON output gains top-level `status: "ok" | "degraded"` marker and a
`config_load_error` string (null on clean runs). All other existing
fields preserved for backward compat.
- Text output prepends a "Config load error" block with Details + Hint
when config failed to parse, then a "Status (degraded)" header on the
main block. Clean runs show the usual "Status" header.
- Doctor path updated to pass the config load error through StatusContext.
Regression test `status_degrades_gracefully_on_malformed_mcp_config_143`:
- Injects a .claw.json with one valid + one malformed mcpServers entry
- Asserts status_context() returns Ok (not Err)
- Asserts config_load_error names the malformed field path
- Asserts workspace/sandbox fields still populated in JSON
- Asserts top-level status is 'degraded'
- Asserts clean config path still returns status: 'ok'
Verified live on /Users/yeongyu/clawd (contains deliberately broken MCP entries):
$ claw status --output-format json
{ "status": "degraded",
"config_load_error": ".../mcpServers.missing-command: missing string field command",
"model": "claude-opus-4-6",
"workspace": {...},
"sandbox": {...},
... }
Phase 2 (typed error object joining #4.44 taxonomy) tracked separately.
Full workspace test green except pre-existing resume_latest flake (unrelated).
Closes ROADMAP #143 phase 1.

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
