Alchemy IaC patterns for deploying TanStack Start apps to Cloudflare Workers with PlanetScale databases via Hyperdrive. Use when setting up new TanStack Start projects, configuring Alchemy deployments, working with PlanetScale/Drizzle migrations, local development with Cloudflare bindings, or deploying to custom domains.
Guide for writing integration tests with Vitest and Testing Library. Use when testing multi-component workflows, database interactions, React components with context providers, or full user flows. Covers the Testing Trophy philosophy (integration > unit), factory patterns for test data, MSW for network mocking, async testing patterns (waitFor, findBy), and custom render with providers. Use this for tests that cross multiple modules or layers of the application.
Handle local database schema changes with Drizzle and PlanetScale. Use when making schema changes to src/db/schema.ts, adding/modifying database tables or columns, or when asked about database migrations. Covers the push-based local development workflow and when to generate migrations.
TanStack Start server-only patterns using createServerOnlyFn and cloudflare:workers env access. Use when: accessing Cloudflare environment variables (APP_URL, STRIPE_SECRET_KEY, etc.), creating server-only utility functions, working with Stripe or other server-only APIs, or when you need to ensure code only runs on the server and throws if called from client. Covers createServerOnlyFn vs createServerFn differences, env access patterns, and centralized server-only utilities.
Look up claim URLs for placeholder users created via manual registration. Use when needing to find the sign-up claim link for a specific email address, debug claim token issues, or verify claim tokens exist in local KV. Triggers on "claim URL", "claim token", "claim link", "placeholder user sign-up link", or requests to find the registration invite link for an email.
Store, search, and manage team memory from AI coding sessions. Use /remember to save observations (conventions, gotchas, debugging tips, architecture decisions, workflows). Use /recall to search memories by semantic query. Use /feedback to rate memory quality (helpful/harmful/irrelevant). Triggers on any request to save, recall, search, or rate team knowledge.
Observability logging patterns for server functions in TanStack Start on Cloudflare Workers. Use when: adding logging to server functions, debugging request flows, tracking entity CRUD operations, correlating logs across requests, adding observability to new features, troubleshooting request tracing, working with PostHog/OpenTelemetry logs. Triggers: logInfo, logError, logWarning, withRequestContext, addRequestContextAttribute, logEntityCreated, request tracing, observability, correlation IDs.
Authentication and authorization patterns for TanStack Start server functions. Use when: adding auth to a new server function, fixing missing authorization, checking user permissions, protecting endpoints, or implementing organizer/volunteer access control for competitions.
