Featuring

Generate _FEATURES.md files — top-down documentation of what a codebase does, organized by feature/capability, anchored to specific source symbols.

tree-sitting tells you WHAT symbols exist. _FEATURES.md tells you WHY they exist and what they accomplish together.

For large codebases, the root _FEATURES.md decomposes into sub-feature files linked by capability area — not by folder structure. An agent starts at the root and is drawn into sub-files only when working on a relevant area.

Dependency

Requires tree-sitting skill. Uses its engine for AST scanning.
