Cosmos

Complete reference for the Cosmos HTTP framework modules (github.com/studiolambda/cosmos). Covers all four modules: contract (interfaces, request/response helpers), router (generic HTTP routing), problem (RFC 9457 error responses), and framework (handlers, middleware, sessions, cache, crypto, hash, database, events). Use when building, consuming, or reviewing any Cosmos module API.

Project-specific Go skill for the Cosmos monorepo. Must use when writing, editing, planning, or reviewing any Go (.go) files in this workspace. Covers code style, naming, documentation, error handling, immutability patterns, testing, and module architecture. Use this skill instead of the global Go skill whenever working inside the Cosmos codebase.
