Dogfooded 2026-04-18 on main HEAD 7859222 from /tmp/cdVV. Extends #86 (silent-drop general case) with two new angles: 1. JSON5-partial acceptance matrix: ACCEPTED (loaded correctly): - trailing comma (one) SILENTLY DROPPED (loaded_config_files=0, zero stderr, exit 0): - line comments (//) - block comments (/* */) - unquoted keys - UTF-8 BOM - single quotes - hex numbers - leading commas - multiple trailing commas 8 cases tested, 1 accepted, 7 silently dropped. The 1 accepted gives false signal of JSON5 tolerance. 2. Alias table creates user-intent inversion: config.rs:856-858: 'default' | 'plan' | 'read-only' => ReadOnly 'acceptEdits' | 'auto' | 'workspace-write' => WorkspaceWrite 'dontAsk' | 'danger-full-access' => DangerFullAccess CRITICAL: 'default' in the config file = ReadOnly no config at all = DangerFullAccess (per #87) These are OPPOSITE modes. Security-inversion chain: user writes: {'// comment', 'defaultMode': 'default'} user intent: read-only parser: rejects comment read_optional_json_object: silently returns Ok(None) config loader: no config present permission_mode: falls back to no-config default = DangerFullAccess ACTUAL RESULT: opposite of intent. ZERO warning. Trace: config.rs:674-692 read_optional_json_object: is_legacy_config = (file_name == '.claw.json') match JsonValue::parse(&contents) { Ok(parsed) => parsed, Err(_error) if is_legacy_config => return Ok(None), Err(error) => return Err(ConfigError::Parse(...)), } is_legacy silent-drop. (#86 covers general case) json.rs JsonValue::parse — custom parser: accepts trailing comma rejects everything else JSON5-ish Fix shape (~80 lines, overlaps with #86): - Pick policy: strict JSON or explicit JSON5. Enforce consistently. - Apply #86 fix here: replace silent-drop with warn-and-continue, structured warning in stderr + JSON surface. - Rename 'default' alias OR map to 'ask' (matches English meaning). - Structure status output: add config_parse_errors:[] field so claws detect silent drops via JSON without stderr-parsing. - Regression matrix per JSON5 feature + security-invariant test. Joins Permission-audit/tool-allow-list (#94, #97, #101, #106, #115) as 6th — this is the CONFIG-PARSE anchor of the permission- posture problem. Complete matrix: #87 absence → DangerFullAccess #101 env-var fail-OPEN → DangerFullAccess #115 init-generated dangerous default → DangerFullAccess #120 config parse-drops → DangerFullAccess Joins Truth-audit on loaded_config_files=0 + permission_mode= danger-full-access inconsistency without config_parse_errors[]. Joins Reporting-surface/config-hygiene (#90, #91, #92, #110, #115, #116) on silent-drop-no-stderr-exit-0 axis. Joins Claude Code migration parity (#103, #109, #116, #117, #119) as 6th — claw-code is strict-where-Claude-was-lax (#116) AND lax-where-Claude-was-strict (#120). Maximum migration confusion. Natural bundles: #86 + #120 — config-parse reliability pair: silent-drop general case (#86) + JSON5-partial-acceptance + alias-inversion (#120) Permission-drift-at-every-boundary 4-way: #87 + #101 + #115 + #120 — absence + env-var + init + config-drop. Complete coverage of every path to DangerFullAccess. Security-critical permission drift audit mega-bundle: #86 + #87 + #101 + #115 + #116 + #120 — five-way sweep of every path to wrong permissions.

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.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
