# PROJECT KNOWLEDGE BASE

**Generated:** 2026-08-16
**Commit:** b71afdd
**Branch:** main

## OVERVIEW
Claw Code: public Rust implementation of the `claw` CLI agent harness (Claude-Code-style). Canonical code lives in `rust/`; the repo is an agent-managed exhibit (harnesses plan/execute/verify per README), not a hand-operated product. `src/` is a companion Python porting/parity workspace, not production code.

## STRUCTURE
```
claw-code/
├── rust/      # canonical Cargo workspace: 11 crates, `claw` binary
├── src/       # Python porting workspace + reference_data/ parity snapshots
├── tests/     # Python unittest validation of src/ + scripts/ (stdlib unittest)
├── docs/      # g0XX gate verification maps + topic docs
├── scripts/   # fmt.sh, dogfood-build.sh, roadmap/board helpers
├── assets/    # README images only

## CONVENTIONS
- `unsafe_code = "forbid"` workspace-wide; every crate opts in via `[lints] workspace = true`; clippy all=warn, pedantic=allow
- Edition 2021, resolver 2, publish=false; no rust-toolchain pin (CI floats stable); no rustfmt.toml/clippy.toml — stock defaults
- Giant flat files by design (main.rs 19.8k, tools/lib.rs 10.9k, commands/lib.rs 7.2k): organization is positional — types → spec table → dispatch → handlers → tests at EOF
- Dual output paths everywhere: `render_x` + `render_x_json`; JSON errors to **stdout**, text errors to **stderr**
- Tests: inline `#[cfg(test)] mod tests` primary; integration tests spawn `CARGO_BIN_EXE_claw` subprocess against mock-anthropic-service; tempfile everywhere; env-mutating tests serialize via env_lock/test_env_lock
- Comments carry issue numbers (#824, #146); gate tests named by roadmap gate (g004_conformance.rs)
- Python side: stdlib only, `python -m unittest`; src/ mixes camelCase (QueryEngine.py) and snake_case filenames

## ANTI-PATTERNS (THIS PROJECT)
- NEVER `cargo install claw-code` — crates.io stub is deprecated and installs `claw-code-deprecated.exe`; build from source
- Forbidden doc strings (CI-enforced by .github/scripts/check_doc_source_of_truth.py): old org links `github.com/Yeachan-Heo/claw-code`, `github.com/code-yeongyu/claw-code`, `discord.gg/6ztZB9jvWq`, `assets/clawd-hero.jpeg`
- Deprecated config keys: `permissionMode` → `permissions.defaultMode`; `enabledPlugins` → `plugins.enabled`; env `RUSTY_CLAUDE_PERMISSION_MODE` is dead
- Direct push to main is policy-blocked (`main_push_forbidden` approval scope)
- Automation lanes must not merge/close remote PRs/issues (docs/anti-slop-triage.md)
- `claw init` must not scaffold `dontAsk` permission mode (regression-pinned in output_format_contract.rs)
- File-level `#![allow(dead_code)]` blocks (main.rs, session_control.rs) are tolerated legacy — do not extend the pattern

## UNIQUE STYLES
- Dogfood build: scripts/dogfood-build.sh injects GIT_SHA; `claw version` provenance must equal HEAD
- Mock parity: rust/mock_parity_scenarios.json drives CLI subprocess vs MockAnthropicService
- Dogfooding uses `CLAW_CONFIG_HOME=$(mktemp -d)` for config isolation
- Env contracts: GIT_SHA (build), CLAW_CONFIG_HOME (config dir), OLLAMA_HOST (provider override), `*_API_KEY`/`*_BASE_URL` per provider

## COMMANDS
```bash
scripts/fmt.sh --check                 # fmt check (apply: scripts/fmt.sh)
cd rust && cargo clippy --workspace --all-targets -- -D warnings
cd rust && cargo test --workspace
cd rust && cargo build -p rusty-claude-cli   # binary: rust/target/debug/claw
python -m unittest discover -s tests   # Python suite
python .github/scripts/check_doc_source_of_truth.py && scripts/roadmap-check-ids.sh   # docs/roadmap CI
```

## NOTES
- `claw` binary comes from crate `rusty-claude-cli` (package/bin name mismatch)
- rust-ci.yml triggers only on rust/**, docs/**, listed meta file changes (path filters)
- CI clippy job runs without `-D warnings` — weaker than the documented gate; known pre-existing failures recorded in docs/g002/g003 maps
- `claw acp` is a status stub, not a real ACP server
- rust/ has committed harness dotdirs (.clawd-agents/, .omc/, .sandbox-home/) — intentional
