Convex backend development guidelines. Use when writing Convex functions, schemas, queries, mutations, actions, or any backend code in a Convex project. Triggers on tasks involving Convex database operations, real-time subscriptions, file storage, or serverless functions.
Analyzes and optimizes application performance across frontend, backend, and database layers. Use when diagnosing slowness, improving load times, optimizing queries, reducing bundle size, or when asked about performance issues.
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Implements error handling patterns, structured logging, retry strategies, circuit breakers, and graceful degradation. Use when designing error handling, setting up logging, implementing retries, adding error tracking, or when asked about error boundaries, log aggregation, alerting, or resilience patterns.
Implements authentication, authorization, encryption, secrets management, and security hardening patterns. Use when designing auth flows, managing secrets, configuring CORS, implementing rate limiting, or when asked about JWT, OAuth, password hashing, API keys, RBAC, or security best practices.
Analyzes codebases to understand structure, tech stack, patterns, and conventions. Use when onboarding to a new project, exploring unfamiliar code, or when asked "how does this work?" or "what's the architecture?"

# Start new feature
git checkout main
git pull
git checkout -b feature/TICKET-123-description
# Commit changes
git add -p # Stage interactively
git commit -m "feat: description"
# Keep up with main
git fetch origin main
git rebase origin/main
# Push and create PR
git push -u origin HEAD
# Amend last commit (before push)
git commit --amend
# Undo last commit (keep changes)
git reset --soft HEAD~1
# Undo last commit (discard changes)
git reset --hard HEAD~1
# Revert a pushed commit
git revert <commit-hash>
# Interactive rebase to clean up
git rebase -i HEAD~3
# Cherry-pick specific commit
git cherry-pick <commit-hash>
# Find which commit broke something
git bisect start
git bisect bad HEAD
git bisect good <known-good-commit>
# Stash with message
git stash push -m "WIP: feature description"
git stash list
git stash pop
Before pushing, validate commits:
Commit Validation:
- [ ] Each commit has a clear, descriptive message
- [ ] Commit type matches the change (feat, fix, etc.)
- [ ] No WIP or temporary commits
- [ ] No secrets or credentials committed
- [ ] Changes are atomic (one logical change per commit)
If validation fails, use git rebase -i to clean up commit history before pushing.
