What problem does it solve? Reading source files to understand a codebase consumes thousands of tokens and still misses cross-file relationships. This Skill retrieves answers from a precomputed graph of the repository, returning exact file:line spans and call edges for a few hundred tokens per query. ## Core Features & Use Cases - Ranked code retrieval: graft ask answers conceptual or locational questions with inline source cruxes, while graft grep exhaustively finds every occurrence of a symbol grouped by enclosing function. - Call-graph tracing: graft callers shows who calls a symbol, what it depends on, and the full transitive blast radius before a rename, refactor, or multi-file change. - Orientation and API inspection: graft map tours an unfamiliar repo's architecture, and graft skeleton shows a file's complete API in roughly 200 tokens. - Use Case: Before renaming a shared function, run graft callers <symbol> --depth 2 to see every file that breaks, then edit at the exact file:line locations returned. ## Quick Start Ask the agent to use graft to explain how a specific feature works in this repository before reading any source files.
