What it does

Once installed, this skill tells an AI coding agent to look up a prebuilt index of the repository (a set of markdown summaries plus a call/reference graph) before searching or reading source files. It offers six commands for answering questions like where code lives, what calls a function, and what a change might break, aiming to use fewer tokens and catch edges a plain text search would miss.

Great for

  • Developers working in a large codebase who want an agent to answer 'where is X' or 'what calls Y' quickly
  • Anyone doing a refactor or rename who needs to know every connected file before editing
  • Teams wanting an architecture overview of an unfamiliar repo via graft map

Skip it if

  • Repos that have not been indexed with graft: the commands depend on a graft/ directory and will not help without it
  • Tasks needing up-to-date markdown docs under graft/ right after editing, since those cards can lag until the end of the turn; the skill itself warns against relying on them there
  • Users expecting a no-setup experience: the skill assumes the graft CLI is installed and available to the agent

Try asking

  • “How does authentication work in this repo? Use graft to find the relevant code.”
  • “Before I rename the function parseConfig, show me everything that calls it.”
  • “Give me an architecture overview of this codebase using graft map.”
  • “Where is rate limiting handled, and what does that file expose?”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Ask a specific conceptual or location question with --source for the most actionable results in one call.
  • For refactors, run graft callers with --depth 2 or --depth all before editing to see the blast radius.
  • If graft returns few or weak hits, switch to graft grep rather than rewording the same question.
