Crash-hunter skill for iOS 26 / Swift 6.2 clinic-architecture codebases that finds and fixes concurrency, memory, and I/O bugs using TDD. Covers data races, actor isolation, retain cycles, SwiftData context misuse, and sync-related failures in Domain/Data/App boundaries. Use when debugging crashes or hard-to-reproduce failures in ios-* and swift-* clinic modules.

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.

iOS Chaos Monkey — Crash-Hunter Best Practices

Adversarial crash-hunting guide for iOS and Swift applications. Contains 47 rules across 8 categories, prioritized by crash severity. Every rule follows TDD: dangerous code first, a failing test that proves the bug, then the fix that makes the test pass.

Clinic Architecture Contract (iOS 26 / Swift 6.2)

All guidance in this skill assumes the clinic modular MVVM-C architecture:

Feature modules import Domain + DesignSystem only (never Data, never sibling features)
App target is the convergence point and owns DependencyContainer, concrete coordinators, and Route Shell wiring
Domain stays pure Swift and defines models plus repository, *Coordinating, ErrorRouting, and AppError contracts
Data owns SwiftData/network/sync/retry/background I/O and implements Domain protocols
Read/write flow defaults to stale-while-revalidate reads and optimistic queued writes
ViewModels call repository protocols directly (no default use-case/interactor layer)

When to Apply

Reference these guidelines when:

Hunting data races, deadlocks, and concurrency crashes in Swift
Auditing memory management for retain cycles and use-after-free
Reviewing async/await code for cancellation and continuation leaks
Stress-testing file I/O and CoreData/SwiftData persistence layers

Priority	Category	Impact	Prefix
1	Data Races & Thread Safety	CRITICAL	`race-`
2	Memory Corruption & Leaks	CRITICAL	`mem-`
3	Deadlocks & Thread Starvation	HIGH	`dead-`
4	Async/Await & Structured Concurrency	HIGH	`async-`
5	File I/O & Persistence Corruption	MEDIUM-HIGH	`io-`
6	Collection & State Mutation	MEDIUM	`mut-`
7	Resource Exhaustion	MEDIUM	`exhaust-`
8	Objective-C Interop Traps	LOW-MEDIUM	`objc-`
