React Best Practices (Upstream)

This is a lightweight stub skill that fetches the latest React Best Practices guidance from Vercel's upstream repository at runtime.

It intentionally avoids vendoring the full rule set so updates can be adopted quickly and attribution stays clear.

Upstream Sources

• Repository: https://github.com/vercel-labs/agent-skills/tree/main/skills/react-best-practices
• Announcement: https://vercel.com/blog/introducing-react-best-practices

Guidelines Source

Fetch fresh guidance before each review:

https://raw.githubusercontent.com/vercel-labs/agent-skills/main/skills/react-best-practices/AGENTS.md

Process

1. Fetch the upstream AGENTS.md.
2. Use it as the authoritative rulebook for React/Next.js performance.
3. Apply relevant rules to the current code/task.

Output Format

• Provide actionable recommendations.
• When possible, cite the upstream rule section heading (and/or a short identifier) so the change can be traced to the upstream guidance.

Quality Checks

• Do not propose micro-optimizations if there are obvious waterfalls or bundle bloat issues.
• Prefer changes that are correct-by-construction (avoid flaky memoization patterns).
• Be explicit about trade-offs and when not to apply a rule.

Offline Snapshot (Optional)

If you want an offline copy of the full rule set, install the upstream repo separately and link it into your Claude Code skills directory.

See skills/vercel-react-best-practices/README.md for an example.
