YeonGyu-Kim e2a43fcd49 feat: #143 phase 1 — claw status degrades gracefully on malformed config
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

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.

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.

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] [!WARNING] 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:

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, not claw. Use .\target\debug\claw.exe or run cargo 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:

  1. Install Rust first — download from https://rustup.rs/ and run the installer. Close and reopen your terminal when it finishes.
  2. Verify Rust is on PATH:
    cargo --version
    
    If this fails, reopen your terminal or run the PATH setup from the Rust installer output, then retry.
  3. 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
    
  4. Run (PowerShell — note .exe and 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
