Reduce controller bloat using Form Requests for auth/validation, small Actions/Services with DTOs, and resource/single-action controllers
Safe database change patterns; when to modify vs add migrations; always pair models with migrations and factories; seeding guidance
Define clear relationships and load data efficiently; prevent N+1, use constraints, counts/sums, and pivot syncing safely
Prevent N+1 queries by eager loading; enable lazy-loading protection in non-production; choose selective fields
Wrap multi-write operations in transactions; use dispatchAfterCommit and idempotency patterns to ensure consistency
Schedule tasks with safety; use withoutOverlapping, onOneServer, and visibility settings for reliable cron execution
Process large datasets efficiently using chunk(), chunkById(), lazy(), and cursor() to reduce memory consumption and improve performance
Server-side authentication primitives for TanStack Start: session cookies (HttpOnly, Secure, SameSite, __Host- prefix), session read/issue/destroy via createServerFn and middleware, OAuth authorization-code flow with state and PKCE, password-reset enumeration defense, CSRF for non-GET RPCs, rate limiting auth endpoints, session rotation on privilege change. Pairs with router-core/auth-and-guards for the routing side.
Redis Query Engine (RQE) guidance covering FT.CREATE schema design, field type selection (TEXT, TAG, NUMERIC, GEO, GEOSHAPE, VECTOR), DIALECT 2 query syntax, efficient FT.SEARCH and FT.AGGREGATE queries, zero-downtime index updates via aliases, and the SKIPINITIALSCAN option. Use when defining a search index on Hash or JSON documents, picking between TEXT and TAG for filtering, writing FT.SEARCH queries with filters and SORTBY, managing or swapping indexes in production, or troubleshooting slow searches with FT.PROFILE.
Use when composing iii primitives into backend architectures: durable workflows, reactive backends, agentic pipelines, event-driven CQRS, effect pipelines, and trigger-transform-action automation.
Auto-activate for sqlspec, SQLSpec, SQLFileLoader, drivers, query builders, named SQL, filters, pagination, Arrow, framework extensions, ADK stores, data dictionary, or observers. Not for ORM repositories.
Builds full-stack Frappe Framework applications end-to-end. Use this skill any time the user mentions: creating or modifying a DocType, writing a controller or lifecycle hook, adding a whitelisted API, setting up a new Frappe app or bench site, building a desk form or list view, creating portal pages, writing background jobs or scheduled tasks, managing permissions or roles, writing Frappe tests, or working with frappe.db / frappe.qb. Also applies when the user says things like "how do I hook into save", "add a field to a DocType", "create a REST endpoint in Frappe", "run bench migrate", or "install an app on a site" — even if they don't explicitly say "Frappe".
