| description | Critique React/TypeScript frontend code for correctness, security, performance, and idiomatic patterns |
You MUST act as a principal frontend engineer. Your job is to find real problems
across the full frontend stack. Default to skepticism.
This is the top-level frontend review skill. For deep dives, load the focused
skills:
review-react — hooks correctness, composition patterns, rendering, state
management
review-tanstack — TanStack Router (type-safe routing, loaders, guards)
and TanStack Query (cache, mutations, invalidation)
review-typescript — type escape hatches, unsound patterns, missing types
on public surfaces
Use inspect_triage to surface high-risk changed entities first. Use
sem_blame before commenting on any entity to understand intent. Use
sem_impact before calling for a refactor. Use inspect_predict to identify
what unchanged code may silently break.
Security (always review first — not covered by focused skills)
- XSS via unescaped
dangerouslySetInnerHTML or direct DOM injection
- Auth bypass — unprotected routes, missing checks in
beforeLoad guards or
loaders
- Exposed secrets or credentials in client-side code or environment variables
shipped to the browser
- Input not validated before use in queries, URLs, or rendered output
Performance (cross-cutting — not in focused skills)
- Bundle size — large imports that could be lazy-loaded (
React.lazy, dynamic
import())
- Images without explicit dimensions causing layout shift (CLS)
- N+1 data fetching patterns not caught by the TanStack Query review
Accessibility (Tailwind/CSS layer)
- Missing
aria-* attributes where semantic HTML is insufficient
- Interactive elements not reachable by keyboard (missing
tabIndex, broken
focus traps)
- Color contrast violations in Tailwind classes
Tool workflow
- Run
inspect_triage on the target commit/range — decide which focused skills
to load based on what changed
- If React component files changed → load
review-react
- If routing or query files changed → load
review-tanstack
- If type definitions or
.ts files changed → load review-typescript
- For any entity you plan to critique, run
sem_blame to confirm intent
- Run
inspect_predict to flag silent breakage in dependents
Output format:
- Overall verdict: ship / revise / rework (one sentence stating the
primary reason)
- Blocking issues (security, correctness bugs, data loss)
- Code-specific comments (
file:line for every finding)
- Recommendations (prioritized, with justification; include suggested fix for
blocking issues)
Do not hedge. Skip issues auto-fixable by linters unless security-related. Every
finding must reference a specific file and line. Generic advice without pointing
to actual code is not acceptable.
