> **Runtime required.** This skill uses Canopy tree notation; canopy-runtime must be active.
>
> **Detect canopy-runtime** — present if either:
> - `canopy-runtime/SKILL.md` exists under `.claude/skills/`, `.github/skills/`, or `.agents/skills/`, OR
> - a canopy-runtime marker block exists in `CLAUDE.md` or `.github/copilot-instructions.md`.
>
> **If neither is present** — install canopy-runtime first (see the `compatibility` field for the source and install options), then re-invoke this skill.
>
> Do not interpret the `## Tree` without canopy-runtime active.

├── IF << critical findings present
│   └── REPORT_FINDINGS << critical
├── IF << warning findings present
│   └── REPORT_FINDINGS << warning
├── IF << info findings present
│   └── REPORT_FINDINGS << info

## Rules

- Only report what is observable in the provided files — do not speculate
- Suggested fixes must be concrete: show the corrected code snippet, not just a description

## Response: target | critical | warnings | info | overall_verdict
