Optional Dependencies

ast-grep (structural code search)

ast-grep provides syntax-aware structural pattern matching for code search. DSO skills use it for cross-file dependency discovery during planning, investigation, and batch overlap analysis. All workflows gracefully fall back to grep when ast-grep is not installed.

Install:

• macOS: brew install ast-grep
• Linux: cargo install ast-grep --locked

The CLI binary is sg. Verify installation: sg --version
