SKILL.md

Skill based on Cosmos SDK, generated from sources/cosmos. Doc path: sources/cosmos/docs/docs/, sources/cosmos/README.md, and sources/cosmos/x/.

The Cosmos SDK is a modular framework for building application-specific blockchains. Applications are composed of modules that own state (via keepers), expose Msg and Query services (Protobuf/gRPC), and plug into the app lifecycle (genesis, BeginBlock, EndBlock, upgrades). Use this skill when implementing or wiring SDK modules, keepers, services, depinject, or migrations.
