Arch Lens

Seven-step interactive architectural review. An Explore sub-agent navigates the codebase the way a developer would — the confusion, file-bouncing, and untestable seams it encounters are the findings. No checklists, no rigid heuristics.

Deep module: small interface surface hiding a large, self-contained implementation. Lets callers test at the boundary. Lets AI agents reason without reading internals.

Quick start

1. If a path argument is given, scope to that directory; otherwise whole repo
2. Load ${CLAUDE_SKILL_DIR}/references/WORKFLOW.md — full step-by-step instructions
3. Load ${CLAUDE_SKILL_DIR}/references/DETECTION-PATTERNS.md
4. Load ${CLAUDE_SKILL_DIR}/references/INTERFACE-DESIGN.md
5. Load ${CLAUDE_SKILL_DIR}/references/RFC-FILE-FORMAT.md
6. Execute the seven steps in WORKFLOW.md
