codebase-overview

Ask the agent for a codebase overview. It inspects the top-level directory layout, reads the README for the project's stated purpose, and checks package manifests to identify stacks and build entry points, then summarizes components and runtime flow.

The overview relies on the top-level directory listing, the main README.md, and package manifests such as Cargo.toml, go.mod, package.json, or pyproject.toml. These reveal the project's purpose, components, and build instructions without deep code indexing.

No. The Skill is read-only for overview requests and explicitly avoids editing project code. It only reads directories, READMEs, and manifests, and may append corrections to its own memory notes if the repo layout has drifted.

Avoid it when you need a deep audit, security review, or line-level analysis of the code. The overview intentionally does not index the whole repository and stays at the architectural level unless you explicitly request a deeper investigation.

It first retrieves any existing architecture notes from memory, then verifies them against the actual repository using directory listings and grep checks. If modules or versions have changed, it appends corrections to memory before presenting the summary.
