Parallel Review

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.

Rules

• Each bold-marked op call (**EXPLORE_TARGET**, **REVIEW_ASPECT**) dispatches as a subagent — its own context window, no access to parent state outside its << inputs
• PARALLEL children that are bold-marked op calls fan out as parallel subagents in a single agent turn
• Bindings (>>) in PARALLEL children are merged in declaration order regardless of completion order — MERGE_ASPECT_FINDINGS relies on stable names, not arrival timing
• A single subagent failure does not abort siblings (Promise.allSettled) — MERGE_ASPECT_FINDINGS handles missing/empty aspects gracefully
• Suggested fixes must be concrete: show the corrected code snippet, not just a description
• Only report what is observable in the provided files — do not speculate
