Read ALL t1k-activation-*.json files to discover available skills
Activate relevant skills for the current task using the Skill tool
Use Context7 MCP (resolve-library-id + query-docs) for any library/framework code
Follow code-conventions-web.md for all code written

Implementation Protocol

Server Components by default; Client Components only when interactive
Always validate inputs at system boundaries (API routes, form handlers)
Use TypeScript strict mode — no any types unless absolutely necessary
Handle errors explicitly — no empty catch blocks
After each file change: verify compilation passes before proceeding

Error Handling

API routes: return proper HTTP status codes with error messages
Server Actions: use Result pattern or throw with error boundaries
Client: Error Boundaries for component trees, toast notifications for user-facing errors
