| description | Pattern library discovery for pattern-first development. Use BEFORE implementing any new feature, creating components, writing API routes, or adding database operations. Ensures existing patterns are checked first. |
Enforce pattern-first development by checking the pattern library before implementing new functionality.
ALWAYS check patterns before writing new code:
ls patterns_library/api/ # API route patterns
ls patterns_library/ui/ # UI component patterns
ls patterns_library/database/ # Database patterns
ls patterns_library/testing/ # Testing patterns
See patterns_library/README.md for the complete index.
If pattern exists: Copy, customize, validate.
If missing: Search codebase, implement following conventions, report gap.
| If you need to... | Use this pattern |
|---|---|
| Create authenticated API endpoint | api/user-context-api.md |
| Create admin-only API endpoint | api/admin-context-api.md |
| Handle external webhooks | api/webhook-handler.md |
| Validate API input with Zod | api/zod-validation-api.md |
| Create protected page | ui/authenticated-page.md |
| Build form with validation | ui/form-with-validation.md |
| Add new table with RLS | database/rls-migration.md |
| Test API endpoints | testing/api-integration-test.md |
patterns_library/README.mdrls-patterns skillfrontend-patterns skillAgent assignment matrix, blocker escalation, and TDM coordination patterns. Use when assigning work to specialists, managing blockers, or coordinating multi-agent workflows.
API route implementation patterns with RLS, Zod validation, and error handling. Use when creating API routes, implementing endpoints, or adding server-side validation.
Documentation templates for ADRs, runbooks, and architecture docs. Use when creating architectural decision records, operational runbooks, or technical documentation.
Deployment workflows, pre-deploy validation, and smoke testing patterns. Use when deploying to staging or production, running smoke tests, or validating deployments.
Frontend patterns for Next.js App Router, Clerk auth, shadcn/Radix UI, and PostHog analytics. Use when building UI components, creating pages, implementing auth flows, or adding analytics events. Ensures consistent UX patterns and accessibility standards.
Advanced git operations including rebase, bisect, cherry-pick, and conflict resolution. Use when rebasing branches, debugging with bisect, cherry-picking commits, or resolving complex merge conflicts.
