Riverpod reactive caching and state management for Dart/Flutter — providers, refs, consumers, auto-dispose, family, mutations, offline persistence, testing, and code generation
Generate agent skills from OSS project documentation in this repository. Reads source docs from sources/{project}/docs/, synthesizes them into skill reference files under skills/{project}/. Use when the user asks to generate skills, create skills from docs, update existing skills, add a new project for skill generation, or mentions skill generation workflow. Also use when working with the skills/ or sources/ directories in this repo.

oRPC is a TypeScript-first RPC framework for building end-to-end typesafe APIs. It provides procedure-based API definitions with input/output validation (Zod, Valibot, ArkType), middleware chains, type-safe error handling, OpenAPI 3.1.1 spec generation, streaming via Event Iterators (SSE), contract-first development, and integrations with TanStack Query, AI SDK, React Server Actions, and more.
