Dense and operational throughout — it never explains basics Claude already knows (React, hooks, RSC) and each section carries executable guidance, with only minor rhetorical flourish that does not pad token budget meaningfully.

Provides copy-paste-ready commands (npx react-doctor --json --json-out, git rev-parse --short HEAD, --scope changed), a concrete recipe URL pattern, file-naming conventions, and table schemas — fully executable, not pseudocode.

Four explicitly sequenced phases (Recon, Audit, Vet, Plans) with validation checkpoints — re-read cited code, confirm at file:line, stop-and-wait for user selection, and mechanical+behavioral plan verification — plus an effort-level table.

References to AUDIT.md and PLAN-TEMPLATE.md are well-signaled and one-level-deep, but neither file exists in the bundle (no references/, scripts/, assets/, or root .md files), so the signaled navigation is broken — capping it below the 'easy navigation' anchor.

Lists multiple concrete actions — survey a React codebase, produce a prioritized audit, write self-contained implementation plans — with an explicit read-only constraint, matching the 'multiple specific concrete actions' anchor.

Clearly answers both what (survey/audit/plan, read-only) and when via an explicit 'Use when...' clause, satisfying the full what+when anchor.

Quotes natural phrasings a user would actually say ('improve the React code', 'audit this codebase', 'make this app faster / more robust', 'roadmap of fixes'), giving good coverage of natural terms.

Explicitly contrasts itself with the react-doctor skill (planner vs. fix-it-now) and gives distinct triggers, carving a clear niche unlikely to trigger the wrong skill.
