TypeScript/JavaScript Code Review Skill

Main Focus

Primary standard: the typescript-write skill. Load it first — it defines the authoring rules this review enforces, alongside frontend/CLAUDE.md and docs/developers-guide/frontend.md.

Adherence to typescript-write is the highest-priority review dimension: rank any violation of its provisions above all other findings. Treat its no-any hard rule (no explicit or implicit any in new code) as blocking, and verify it with the LSP rather than by eye.

Review in this priority order:

1. Violations of typescript-write provisions — no-any, type tightening, type modeling, null/undefined handling, naming, structure, comments. Highest priority; block on the no-any rule.
2. Compliance with frontend/CLAUDE.md.
3. Readability and maintainability.
4. Appropriate test coverage.

Blind spots — act as the missing reviewer

These rarely surface in team reviews, so this skill should raise them. They are additive — raise them, but rank them below typescript-write violations:

• Accessibility. Interactive elements need keyboard support, focus management, and accessible names. Flag missing aria-label/aria-labelledby, non-semantic click targets, modals without focus trap, icon-only buttons without labels, and form inputs without a linked label.
• Performance. Flag areas that scale poorly and aren't memoized; inline object/array literals passed to memoized children; effects that fire on every batch of a progressive load; and new dependencies added to hot paths.
• Security. Evaluate potential security issues in new code.
• Bundle size. Flag new large dependencies, default imports from icon or util libs, and heavy modules imported at route-load time.
• Analytics. User-facing flows should emit tracking events. If a PR adds a new flow (button, modal, navigation) without a tracking event, ask whether one is expected.
