# CLAUDE.md Review Findings

**Date**: February 15, 2026
**Scope**: Full 17-area codebase audit against CLAUDE.md
**Method**: Systematic source code analysis using review-prompt.md

---

## Summary

The current CLAUDE.md has **5 incorrect claims**, **10 missing sections**, and **3 minor inaccuracies**. The most impactful issues are wrong counts, a false provider claim, and a misleading description of the CLI/API relationship.

---

## High Priority: Incorrect or Misleading

### 1. Pattern count wrong (line 197)
- **CLAUDE.md says**: `patterns/breaking.yaml - CLI patterns (72 total, feature-focused)`
- **Reality**: 107 patterns (34 universal + 73 domain-specific across 14 domains)
- **Note**: Line 222 correctly says 107, so the file contradicts itself

### 2. Provider support claim is false (line 155)
- **CLAUDE.md says**: `Supports multiple providers: Anthropic (default), OpenAI, Ollama`
- **Reality**: Only Anthropic is registered in `PROVIDER_REGISTRY` (factory.py:10-12). OpenAI and Ollama have default model names defined but **no implementation exists**.
- **Impact**: Developers will try to use OpenAI/Ollama and get `ValueError: Unsupported provider`

### 3. CLI described as "thin wrapper" — it's not (line 225)
- **CLAUDE.md says**: `gremlin/cli.py: CLI entry point (thin wrapper around api.py)`
- **Reality**: CLI reimplements the full pipeline independently (loads patterns, builds prompts, calls provider, renders output). It does NOT call `Gremlin.analyze()`.
- **Impact**: Changes to api.py don't automatically flow to CLI behavior

### 4. Test count wrong (line 227)
- **CLAUDE.md says**: `tests/test_api.py: Comprehensive API test suite (23 tests)`
- **Reality**: 50 tests across 6 files (test_api: 25, test_cli_validate: 5, test_inference: 6, test_patterns: 7, test_validator: 7)

### 5. Testing philosophy claim is wrong (line 254-256)
- **CLAUDE.md says**: `No LLM mocking - actual API calls are integration tests`
- **Reality**: Tests extensively use `unittest.mock.patch` to mock LLM providers. Only 2 tests in `TestGremlinIntegration` make actual API calls (gated by `ANTHROPIC_API_KEY`).

---

## Medium Priority: Missing Information

### 6. `learn` command not documented
- The `gremlin learn` command exists in cli.py with `--domain` and `--source` flags
- Converts incident descriptions to "What if?" patterns and saves to `patterns/incidents/`
- Not mentioned anywhere in CLAUDE.md

### 7. `--validate` flag not shown in usage examples
- The `--validate` / `-V` flag exists on `gremlin review`
- Runs a second LLM pass to filter hallucinated risks
- Exists in CLI only, not wired into the API's `analyze()` method
- CLAUDE.md lists it under "Running the Tool" but doesn't show it in examples

### 8. `GREMLIN_PROVIDER` environment variable missing
- CLAUDE.md lists 2 env vars; there are actually 3:
  - `ANTHROPIC_API_KEY` (required) — documented
  - `GREMLIN_MODEL` (optional) — documented
  - `GREMLIN_PROVIDER` (optional, default: "anthropic") — **missing**

### 9. `.gremlin/patterns.yaml` project-level override not documented
- CLI checks `Path.cwd() / ".gremlin" / "patterns.yaml"` and merges with built-in patterns (cli.py:148-156)
- Useful for teams adding project-specific patterns
- Not mentioned in CLAUDE.md

### 10. CI/CD pipeline not documented
- `.github/workflows/ci.yml` exists
- Runs on push/PR to main: ruff check + pytest with coverage on Python 3.10/3.11/3.12
- Uploads coverage to Codecov
- Not mentioned in CLAUDE.md

### 11. Validator module not in Important Files
- `gremlin/core/validator.py` — LLM-as-judge risk quality checker
- Wired into CLI `--validate` flag but NOT into the API
- Not listed in CLAUDE.md's Important Files section

### 12. Architecture diagrams not referenced
- `docs/architecture.drawio`, `docs/architecture-high-level.png`, `docs/architecture-data-flow.png` exist
- Created in PR #26 but never added to CLAUDE.md

### 13. Agent bridge module not documented
- `gremlin/integrations/agent_bridge.py` provides CLI detection and invocation for the agent
- Not mentioned in Important Files

### 14. Code-review pattern count wrong
- CLAUDE.md says "45-50 code-review patterns"
- Actual: 65 patterns (16 universal + 49 domain-specific across 10 domains)

### 15. Incidents directory and learn workflow not documented
- `gremlin/patterns/incidents/chitram.yaml` — 13 patterns learned from real incidents
- `gremlin learn` populates this directory
- None of this is in CLAUDE.md

---

## Low Priority: Minor Inaccuracies

### 16. Line references are outdated
- CLAUDE.md: "Context Resolution (cli.py:29-55)" — line numbers shifted after refactors
- Should either update line numbers or remove them (they'll drift again)

### 17. Deprecated module still present
- `gremlin/llm/claude.py` marked DEPRECATED, no longer imported after PR #27
- Could be mentioned as a gotcha for developers who find it

### 18. `demo_api.py` not documented
- Root-level demo script showing Phase 1 API usage
- Minor, but useful for onboarding
