continuous-learning
Continuous learning system that extracts reusable knowledge from work sessions.
Triggers: (1) /continuous-learning command to review session learnings, (2) "save this as a skill"
or "extract a skill from this", (3) "what did we learn?", (4) After any task involving
non-obvious debugging, workarounds, or trial-and-error discovery. Creates new Claude Code
skills when valuable, reusable knowledge is identified.

typescript-circular-dependency
Detect and resolve TypeScript/JavaScript circular import dependencies. Use when:
(1) "Cannot access 'X' before initialization" at runtime, (2) Import returns
undefined unexpectedly, (3) "ReferenceError: Cannot access X before initialization",
(4) Type errors that disappear when you change import order, (5) Jest/Vitest tests
fail with undefined imports that work in browser.

prisma-connection-pool-exhaustion
Fix Prisma "Too many connections" and connection pool exhaustion errors in
serverless environments (Vercel, AWS Lambda, Netlify). Use when: (1) Error
"P2024: Timed out fetching a new connection from the pool", (2) PostgreSQL
"too many connections for role", (3) Database works locally but fails in
production serverless, (4) Intermittent database timeouts under load.

Debug getServerSideProps and getStaticProps errors in Next.js. Use when:
(1) Page shows generic error but browser console is empty, (2) API routes
return 500 with no details, (3) Server-side code fails silently, (4) Error
only occurs on refresh not client navigation. Check terminal/server logs
instead of browser for actual error messages.
