Apply when writing, structuring, or reviewing application code — covers SOLID, YAGNI, DRY, composition over inheritance, Gang of Four patterns (used sparingly), Command/Query Separation, the banned Repository pattern, /lib application logic, and /tests BDD coverage. Load whenever designing classes, services, modules, or deciding where code lives.

Apply whenever you write or modify ANY class, method, or .ts file — not only when editing comments. Every class and method you author must be commented per this skill, so load it alongside code-architecture during all code-writing. Covers commenting classes and methods (not internals), writing for a future LLM reader, and avoiding noise comments on properties or obvious code.

Apply when reading or writing data, designing schema, choosing a datastore, or wiring persistence — covers Drizzle ORM usage, SQLite for dev/test, Cloudflare D1 for prod, Firebase Storage links, and the absolute ban on the Repository pattern. Load whenever touching the database, migrations, queries, or storage.

Apply when choosing runtime/framework/deploy targets or scaffolding an app, API, route, webhook, or deployment — covers Bun with TypeScript, Cloudflare Workers, D1, Firebase Storage, Resend, and Stripe webhooks. Load whenever setting up endpoints, configuring runtime, or planning deployment.

Apply when writing, reviewing, or planning tests — covers BDD style, happy-path AND sad-path coverage, deriving tests from user stories, and using bun:test. Load whenever creating *.test.ts files, adding coverage, or turning a requirement into a spec.
