Pattern for building MCP servers in Next.js with mcp-handler, shared Zod schemas, and reusable server actions.
TypeScript code quality patterns for writing and reviewing code. Covers type safety, clean code, functional patterns, Zod usage, and error handling. Triggers on: add entity, create service, add repository, create comparator, add formatter, deployment stage, GraphQL query, GraphQL mutation, bootstrap method, diff support, command handler, Zod schema, error class, implement feature, add function, refactor code, clean code, functional patterns, map filter reduce, satisfies operator, type guard, code review, PR review, check implementation, audit code, fix types.
Use when working with validation errors -- returnValidationErrors, formatted vs flattened shapes, custom validation error shapes, throwValidationErrors, or displaying field-level and form-level errors
Use when creating or configuring a next-safe-action client, defining actions with input/output validation, handling server errors, or setting up createSafeActionClient with Standard Schema (Zod, Yup, Valibot)
Develop AI agents, tools, and workflows with Mastra v1 Beta and Hono servers. This skill should be used when creating Mastra agents, defining tools with Zod schemas, building workflows with step data flow, setting up Hono API servers with Mastra adapters, or implementing agent networks. Keywords: mastra, hono, agent, tool, workflow, AI, LLM, typescript, API, MCP.
How to add or modify Next.js experimental feature flags end-to-end. Use when editing config-shared.ts, config-schema.ts, define-env-plugin.ts, next-server.ts, export/worker.ts, or module.compiled.js. Covers type declaration, zod schema, build-time injection, runtime env plumbing, and the decision between runtime env-var branching vs separate bundle variants.
Design MCP prompts to expose reusable prompt templates. Use when creating parameterized prompts in xmcp.
Guide for adding new environment variables to the codebase. Ensures env.ts schemas include descriptions and .env.example is kept in sync. Triggers on: add env variable, new environment variable, env.ts change, add config variable, INKEEP_, adding to .env.
Creates and registers Tambo components - generative (AI creates on-demand) and interactable (pre-placed, AI updates). Use when defining components, working with TamboComponent, withInteractable, propsSchema, or registering components for AI to render or update.
Enforces the CodeBelt TypeScript and React code style guide for project structure, naming conventions, component patterns, service patterns, testing, and TypeScript rules. Use when writing, reviewing, or refactoring TypeScript or React code, creating new files or components, organizing project directories, writing tests, defining Zod schemas, or when the user mentions code style, conventions, linting, file organization, or naming patterns.
Write and refactor TypeScript code in repos that use Effect-TS services, Zod schemas, event-sourced persistence, and namespace-driven architecture. Use this skill when implementing features, fixing bugs, writing tests, or refactoring in opencode or any TypeScript codebase built on the same stack (Effect DI, Drizzle ORM, Hono routes, Bun runtime). Triggers on tasks involving Effect services, namespace modules, Zod schema definitions, SyncEvent patterns, tool implementations, test writing, or code review in Effect-based TypeScript projects.
Ban `as` type assertions in a package via the `@typescript-eslint/consistent-type-assertions` lint rule, replacing them with compiler-verified type-safe alternatives. Use when enabling the assertion ban in a new package or fixing violations in an existing one.
