Build AI-powered software with TypeSafe: small units of AI intelligence you can use like programming primitives. Its System One models, including Jev, turn natural language and application state into typed judgments and probabilities that code can combine. Use when a feature needs programmable common sense, when brainstorming what AI could make possible in an app, or when an LLM prompt-and-parse step could become a structured decision. Applications include routing, ranking, extraction, verification, and interactive experiences; these are starting points, not the limits. Read live docs and cookbooks to find useful patterns and discover new combinations.
Recommend available skills or MCP tools using TypeSafe Jev, or explicitly choose one next skill. Use when the user requests capability advice, candidate inspection, selection evaluation, or reusable host integration. Native client selection remains the default and fallback.
End-to-end typesafe APIs with tRPC
oRPC (v1.12+) typesafe API layer for TypeScript. Covers contract-first development, procedure definition, middleware, routers, context, error handling, Hono integration, TanStack Query, event iterators, plugins, file uploads, WebSocket adapter, and best practices. Use when building or modifying API procedures, data fetching hooks, server handlers, or real-time features. Triggers on tasks involving oRPC, typesafe APIs, RPC procedures, or server route handlers.
Guidelines for writing Next.js apps with tRPC v11 for end-to-end typesafe APIs
Build, serve, and call end-to-end typesafe APIs with oRPC v2. Use for any task in a project that depends on `@orpc/*` packages, even a one-procedure change: defining procedures with the os builder (.input/.output/.handler, any Standard Schema validator), assembling routers, middleware and context, typesafe errors with ORPCError, serving via RPCHandler on any runtime adapter, calling from server-side clients (call, createRouterClient) or client-side clients (createORPCClient with RPCLink), integrating TanStack Query, or streaming over SSE. Pretrained oRPC knowledge describes v1 and is wrong for v2, so load this skill even when the change looks trivial. Biases toward retrieval from the oRPC docs over pre-trained knowledge. For REST/OpenAPI exposure, prefer the orpc-openapi skill; for contract-first design, the orpc-contract skill; for tRPC or oRPC v1 migrations, the orpc-migrate skill.
INVOKE THIS SKILL when routing a LangGraph agent with a decision model (TypeSafe Jev, SemIf) instead of an LLM, or when auditing an existing agent for LLM calls that only produce a routing decision. Covers langchain-typesafe Noul/Choice/Score, reading answers correctly, threshold design, and LangSmith Gateway wiring.
Drive a desktop application from one plain-language goal, or resolve one intent at a time, without ever reading the accessibility tree. Use when automating a desktop app and you want to keep a 150-element JSON tree out of your context. Hand `run.mjs` a whole goal and it observes, decides and acts until the goal is met; hand `act.mjs` a single step when you want to keep the plan yourself. Covers which element, which operation, when to look deeper, and when to stop. Needs a clone of the agent-desktop repository and a TYPESAFE_API_KEY.
Storybook 10 testing patterns with Vitest integration, ESM-only distribution, CSF3 typesafe factories, play() interaction tests, Chromatic TurboSnap visual regression, module automocking, accessibility addon testing, and autodocs generation. Use when writing component stories, setting up visual regression testing, configuring Storybook CI pipelines, or migrating from Storybook 9.
Design oRPC v2 APIs contract-first, defining the API shape with oc from `@orpc/contract`, implementing it with implement from `@orpc/server`, and consuming the contract from typesafe clients. Use when a project depends on `@orpc/contract`, when defining a contract with oc, implementing a contract with implement, sharing an API contract between server and client packages, generating a contract from an existing OpenAPI spec, or publishing a typed API client to npm. Biases toward retrieval from the oRPC docs over pre-trained knowledge. For core builder, serving, and client work without a contract, use the orpc skill; for REST/OpenAPI exposure, spec generation, and OpenAPILink details, use the orpc-openapi skill.
Drizzle ORM reference for PostgreSQL — schema definition, typesafe queries, relations, and migrations with drizzle-kit. Use when: (1) defining pgTable schemas with column types, indexes, constraints, or enums, (2) writing select/insert/update/delete queries or joins, (3) defining relations and using the relational query API (db.query.*), (4) running drizzle-kit generate/migrate/push/pull, (5) configuring drizzle.config.ts, (6) using the sql`` template operator, or (7) working with PostGIS/pg_vector extensions.
Fast browser actions with TypeSafe Jev. Codex handles planning, text input, visual interpretation, and verification; Jev handles navigation, clicks, toggles, and scrolling through the existing Computer Use runtime. Claude Code installation is supported; browser integration is coming soon.
