Interactive tutorial that guides engineers through building their own coding agent (agentic loop) from scratch using raw HTTP calls to an LLM API. Supports Gemini, OpenAI (and compatible endpoints), and Anthropic. Supports TypeScript, Python, Go, and Ruby. Detects progress automatically. Use when someone says "build an agent", "teach me agents", or "/build-agent".
OpenAPI 3.1 specification, schema design, and code generation. Use when designing REST APIs, generating TypeScript clients, or creating API documentation. Use for openapi, swagger, api-spec, schema, code-generation, api-docs, openapi-typescript, zod-openapi.
React Native with Expo framework for building native mobile apps on Android, iOS, and web from a single TypeScript codebase. Covers Expo Router file-based navigation (stack, tabs, drawer), EAS Build/Submit/Update for CI/CD and OTA updates, expo-dev-client for custom development builds, Expo Modules API for native Swift/Kotlin modules, core RN patterns (StyleSheet, FlatList, Platform-specific code), native device APIs (camera, notifications, haptics), and NativeWind for Tailwind CSS styling. Use when building React Native apps with Expo, configuring Expo Router navigation, setting up EAS Build pipelines, implementing OTA updates, creating native modules, or integrating device APIs like camera and push notifications.
Use when creating OpenCode plugins that hook into command, file, LSP, message, permission, server, session, todo, tool, or TUI events - provides plugin structure, event API specifications, and implementation patterns for JavaScript/TypeScript event-driven modules
Fast linting/formatting for TypeScript/React. Use when setting up linter, migrating from ESLint/Prettier, or running code quality checks.
Guide for oRPC — a type-safe RPC framework combining end-to-end type safety with OpenAPI compliance. Use when user explicitly mentions "oRPC" or asks to "create oRPC procedures", "set up oRPC server", "configure oRPC client", "add oRPC middleware", "define oRPC router", "use oRPC with Next.js/Express/Hono/Fastify", "generate OpenAPI spec with oRPC", "integrate oRPC with TanStack Query", "stream with oRPC", "handle errors in oRPC", "set up oRPC contract-first", "migrate from tRPC to oRPC", or asks about oRPC procedures, routers, middleware, context, plugins, adapters, or server actions. Covers server setup, client creation, middleware chains, error handling, OpenAPI generation, file uploads, event iterators (SSE/streaming), server actions, contract-first development, and framework adapter integrations. Do NOT use for generic RPC/gRPC questions, tRPC-only questions (without migration context), or general TypeScript API development without oRPC.
Perform systematic self-review of code changes before commits using structured checklist. Validates architecture boundaries, code quality, test coverage, documentation, and project-specific anti-patterns. Use before committing, creating PRs, or when user says "review my changes", "self-review", "check my code". Adapts to Python, JavaScript, TypeScript, Go, Rust projects.
Automated UI development loop: dev server + browser + implement + verify + fix. Launches dev server, implements via frontend-design skill, checks for errors (console, TypeScript, network), and iterates up to 5 times. USE WHEN: "implement next feature", "implement [description]", "verify the UI". NOT for one-off design/code tasks — use frontend-design directly for those. 6. Reports completion or escalates with detailed report **Triggers:** - "implement next feature", "implement the hero section" - "verify this implementation", "check the UI" - "fix the errors", "iterate on this" - "start dev server", "manage server"
Implement field-level encryption with @cipherstash/stack. Covers schema definition, encrypt/decrypt operations, searchable encryption (equality, free-text, range, JSON), bulk operations, model operations, identity-aware encryption with LockContext, multi-tenant keysets, and the full TypeScript type system. Use when adding encryption to a project, defining encrypted schemas, or working with the CipherStash Encryption API.
MeshJS patterns: tx building, wallet connectors, script interactions. TypeScript/JavaScript Cardano development.
TronWeb — JavaScript/TypeScript SDK for TRON (HTTP API, contracts, transactions, events).
Apply the "How I Made Your Machine" coding style guide to implementation, refactoring, and code review tasks across TypeScript, Rust, and Python. Use when a request asks for this style guide, when improving maintainability and type safety, when modeling domain concepts with explicit variants/types, or when enforcing behavior-first testing.
