Triad is a TypeScript/Node.js framework where API specification, implementation, validation, and testing are a single source of truth.
Skill Claude CodeCodex
Use when mounting a TriadJS router on Fastify (triadPlugin), Express (createTriadRouter), or Hono (createTriadHono), configuring per-request services, or choosing which adapter fits a deployment target. Fastify is the only adapter with WebSocket support.
Skill Claude CodeCodex
Use when writing TriadJS BDD scenarios, wiring .given().when().then().and() chains, choosing assertion phrases, using scenario.auto() for schema-derived adversarial tests, or debugging "Unrecognized assertion" errors. Authoritative phrase table for the heuristic assertion parser.

Use when declaring TriadJS WebSocket channels with channel(), wiring onConnect/onDisconnect/handlers, typing per-connection state via the phantom witness, using ctx.broadcast/ctx.broadcastOthers/ctx.send, or implementing first-message auth for browsers.
Skill Claude CodeCodex
Use when running the triad CLI — triad test, triad docs, triad gherkin, triad db generate, triad validate, triad fuzz — configuring triad.config.ts, debugging CLI errors, or understanding flag behavior.
Skill Claude CodeCodex
Use when generating Drizzle ORM schemas from TriadJS models via triad db generate, choosing a dialect (sqlite/postgres/mysql), declaring .storage() hints on fields, designing repositories around the generated tables, or handling isUniqueViolation for domain-level conflict detection.
Skill Claude CodeCodex
Use when declaring TriadJS HTTP endpoints with endpoint(), wiring request/responses/handler/beforeHandler, building a router with createRouter and router.context() bounded contexts, designing auth via beforeHandler, or debugging ctx.respond/ctx.state/ctx.services.
Skill Claude CodeCodex
Use when designing TriadJS schemas — t.model(), t.value(), primitives (t.string, t.int32, t.enum, t.datetime, t.file), collections (t.array, t.record, t.tuple, t.union), model operations (.pick, .omit, .partial, .extend, .merge, .named), or DDD entities and value objects.

Skill Claude CodeCodex
Use when wiring dependency injection for TriadJS — declaring services, module-augmenting ServiceContainer, creating createServices() factories, and threading repositories/clients onto ctx.services with full type inference and no casts.
Skill Claude CodeCodex
Use when wiring the TriadJS test runner — triad.config.ts, test-setup.ts default-exported services factory, per-scenario DB isolation, teardown, fixtures, and scenario.auto() for schema-derived adversarial tests. Tests run in-process — no HTTP, no adapter middleware.
Skill Claude CodeCodex
Use whenever the user mentions TriadJS, the @triadjs/ packages, t.model(), endpoint(), channel(), scenario(), triad test, triad docs, or asks to build a TypeScript backend with validation + OpenAPI + BDD tests from one definition. Overview of the framework and pointer to the focused sub-skills.
