Vercel React Performance Rules
Source: vercel-labs/agent-skills (react-best-practices)
How to Use
- Find relevant rule(s) from the index below
- Read cached rule:
~/.claude/skills/vercel-react/cache/{rule}.md - If not cached:
bash ~/.claude/skills/vercel-react/scripts/fetch-rule.sh {rule} - Bulk sync:
bash ~/.claude/skills/vercel-react/scripts/sync.sh
Behavior
- Code review / writing: check CRITICAL + HIGH rules first
- Only check MEDIUM/LOW if user specifically asks for deep optimization
- Fetch only the rules relevant to the code at hand (not all 58)
Priority Index
1. Eliminating Waterfalls — CRITICAL
| Rule | Description | | ------------------------- | ---------------------------------------------- | | async-defer-await | Move await into branches where actually used | | async-parallel | Promise.all() for independent operations | | async-dependencies | better-all for partial dependencies | | async-api-routes | Start promises early, await late in API routes | | async-suspense-boundaries | Suspense to stream content |
2. Bundle Size — CRITICAL
| Rule | Description | | ------------------------ | ------------------------------------------- | | bundle-barrel-imports | Import directly, avoid barrel files | | bundle-dynamic-imports | next/dynamic for heavy components | | bundle-defer-third-party | Load analytics/logging after hydration | | bundle-conditional | Load modules only when feature is activated | | bundle-preload | Preload on hover/focus for perceived speed |
3. Server-Side — HIGH
| Rule | Description | | ------------------------ | ------------------------------------------- | | server-auth-actions | Authenticate server actions like API routes | | server-cache-react | React.cache() for per-request dedup | | server-cache-lru | LRU cache for cross-request caching | | server-dedup-props | Avoid duplicate serialization in RSC props | | server-hoist-static-io | Hoist static I/O to module level | | server-serialization | Minimize data passed to client components | | server-parallel-fetching | Restructure to parallelize fetches | | server-after-nonblocking | after() for non-blocking operations |
4-8. MEDIUM / LOW Priority
Client-Side Data (MEDIUM-HIGH), Re-render (MEDIUM), Rendering (MEDIUM), JS Performance (LOW-MEDIUM), Advanced (LOW) — check only when user specifically asks for deep optimization.

Judge a SKILL.md against craft axes (single responsibility, description distinctiveness, imperative voice, verifiable completion, calibration, progressive disclosure) and apply the fixes the audit surfaces. Do not use for format-presence-only checks (use reviewer-prompt) or reproducibility loops (use /tuning).

Extract repository spec while detecting bugs, spec gaps, and consistency drift via dual-purpose documentation. OUTCOME.md-axis question-driven exploration with ephemeral output. Do NOT use for code review (use /audit or /polish), feature implementation (use /code), planning only (use /think), or single-bug fix (use /fix).
