drizzle-nextjs-postgres

Drizzle ORM against PostgreSQL inside a Next.js App Router app. Covers client construction (globalThis singleton across HMR, serverless pool sizing, `prepare:false` behind PgBouncer/Supavisor, driver choice when you need interactive transactions, `server-only`), reads in Server Components under Next.js 16 Cache Components (`use cache` superseding `unstable_cache` and the `revalidate`/`dynamic` segment configs, Suspense boundaries, React `cache()` dedupe), Server Actions (authorization inside the action, `updateTag` vs `revalidateTag`, `after()`), Postgres schema types (timestamptz, identity vs serial, jsonb, numeric-as-string, bigint modes), drizzle-kit migrations (generate vs push, CONCURRENTLY outside the migrator, NOT VALID constraints, rename prompts), transactions and pooled connections, and Postgres query traps (keyset pagination, count cost, driver-dependent `db.execute()` shape, NOT IN nulls, prepared statements). Use when writing or reviewing Drizzle + Postgres code in Next.js.

relational-data-modeling

Corrects the wrong defaults a model has when designing a relational schema — the DDL decisions an experienced engineer makes differently. Use when creating or reviewing tables, migrations, ER models, or ORM schema definitions. Covers identity and keys (surrogate vs natural, identity vs serial, uuidv7, composite keys that make cross-tenant references impossible), relationships (polymorphic foreign keys the database cannot enforce, referential actions, unindexed FK columns, disjoint subtypes), invariants the engine can prove instead of application code (EXCLUDE, partial unique indexes, CHECK limits, deferrable cycles, NOT VALID), types (timestamptz, exact money, range types, enum vs lookup table), derived and encoded data (generated columns, JSONB as an escape hatch), and time (events vs in-place updates, soft-delete flags that silently disable constraints, temporal keys). NOT for query tuning, index selection for read paths, or connection pooling.

relational-database-design

Distills a logical relational-database design methodology into rules an agent applies while designing or reviewing a schema. Covers the design sequence (mission → tables → fields → keys → relationships → business rules → views → integrity review), one-subject-per-table decomposition, atomic single-valued fields, candidate/primary/foreign keys, relationship types with deletion rules and participation, the four levels of data integrity, database-vs-application business rules, validation tables, views for derived data, and the flat-file / spreadsheet / RDBMS-driven antipatterns to avoid. The structure is logical and RDBMS-agnostic, and normalized by construction. Use when designing a new relational schema, reviewing or refactoring an existing one, resolving redundant or repeating data, choosing keys, modeling relationships, or deciding where a constraint belongs.

description	Orval OpenAPI TypeScript client generation best practices. This skill should be used when configuring Orval, generating TypeScript clients from OpenAPI specs, setting up React Query/SWR hooks, creating custom mutators, or writing MSW mocks. Triggers on tasks involving orval.config.ts, OpenAPI codegen, API client setup, or mock generation.

Orval OpenAPI Best Practices

Comprehensive guide for generating type-safe TypeScript clients from OpenAPI specifications using Orval. Contains 42 rules across 8 categories, prioritized by impact to guide automated configuration, client generation, and testing setup.

When to Apply

Reference these guidelines when:

Configuring Orval for a new project
Setting up OpenAPI-based TypeScript client generation
Integrating React Query, SWR, or Vue Query with generated hooks
Creating custom mutators for authentication and error handling
Generating MSW mocks for testing

Rule Categories by Priority

Priority	Category	Impact	Prefix
1	OpenAPI Specification Quality	CRITICAL	`spec-`
2	Configuration Architecture	CRITICAL	`orvalcfg-`
3	Output Structure & Organization	HIGH	`output-`
4	Custom Client & Mutators	HIGH	`mutator-`
5	Query Library Integration	MEDIUM-HIGH	`oquery-`
6	Type Safety & Validation	MEDIUM	`types-`
7	Mock Generation & Testing	MEDIUM	`mock-`
8	Advanced Patterns	LOW	`adv-`

Quick Reference

1. OpenAPI Specification Quality (CRITICAL)

spec-operationid-unique - Use unique and descriptive operationIds
spec-schemas-reusable - Define reusable schemas in components
spec-tags-organization - Organize operations with tags
spec-response-types - Define all response types explicitly
spec-required-fields - Mark required fields explicitly

2. Configuration Architecture (CRITICAL)

orvalcfg-mode-selection - Choose output mode based on API size
orvalcfg-client-selection - Select client based on framework requirements
orvalcfg-separate-schemas - Separate schemas into dedicated directory
orvalcfg-input-validation - Validate OpenAPI spec before generation
orvalcfg-baseurl-setup - Configure base URL properly
orvalcfg-prettier-format - Enable automatic code formatting

3. Output Structure & Organization (HIGH)

output-file-extension - Use distinct file extensions for generated code
output-index-files - Generate index files for clean imports
output-naming-convention - Configure consistent naming conventions
output-clean-target - Enable clean mode for consistent regeneration
output-headers-enabled - Enable headers in generated functions

4. Custom Client & Mutators (HIGH)

mutator-custom-instance - Use custom mutator for HTTP client configuration
mutator-error-types - Export custom error types from mutator
mutator-body-wrapper - Export body type wrapper for request transformation
mutator-interceptors - Use interceptors for cross-cutting concerns
mutator-token-refresh - Handle token refresh in mutator
mutator-fetch-client - Use fetch mutator for smaller bundle size

5. Query Library Integration (MEDIUM-HIGH)

oquery-hook-options - Configure default query options globally
oquery-key-export - Export query keys for cache invalidation
oquery-infinite-queries - Enable infinite queries for paginated endpoints
oquery-suspense-support - Enable suspense mode for streaming UX
oquery-signal-cancellation - Pass AbortSignal for request cancellation
oquery-mutation-callbacks - Use generated mutation options types

6. Type Safety & Validation (MEDIUM)

types-zod-validation - Generate Zod schemas for runtime validation
types-zod-strict - Enable Zod strict mode for safer validation
types-zod-coerce - Use Zod coercion for type transformations
types-use-dates - Enable useDates for Date type generation
types-bigint-support - Enable useBigInt for large integer support

7. Mock Generation & Testing (MEDIUM)

mock-msw-generation - Generate MSW handlers for testing
mock-use-examples - Use OpenAPI examples for realistic mocks
mock-delay-config - Configure mock response delays
mock-http-status - Generate mocks for all HTTP status codes
mock-index-files - Generate mock index files for easy setup

8. Advanced Patterns (LOW)

adv-input-transformer - Use input transformer for spec preprocessing
adv-operation-override - Override settings per operation
adv-output-transformer - Use output transformer for generated code modification
adv-form-data-handling - Configure form data serialization

How to Use

Read individual reference files for detailed explanations and code examples:

Section definitions - Category structure and impact levels
Rule template - Template for adding new rules
Example: spec-operationid-unique
