graphtrail SKILL.md skillA
graphtrail from escoffier-labs/skillet is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add escoffier-labs/skillet/graphtrail@v0.1.1Pins v0.1.1 in mdr.lock. Pin the fingerprint instead.

Use when answering structural code questions in an indexed repo - who calls this, what does this call, what breaks if I change it, what changed between two versions. Reach for it BEFORE grep whenever the question is about relationships between symbols rather than text. Triggers include "who calls", "what uses", "blast radius", "impact of changing", "callers of", "what depends on", and reviewing a diff's structural effect.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# graphtrail GraphTrail keeps a SQLite code graph (symbols, imports, call edges) per repo, synced incrementally and queryable through 9 MCP tools. The point of this skill: for structural questions, the graph answers in one call what grep answers in five speculative ones, and the graph knows about relationships grep cannot see (cross-file call resolution through imports, transitive impact, before/after structure). ## When to use which tool - **"Who calls X?"** -> `callers`. **"What does X call?"** -> `callees`. Exact answers from resolved call edges, including cross-file calls resolved through imports. grep finds the string `X(`; the graph finds the actual callers of THIS `X`. - **"What breaks if I change X?"** -> `impact` with `--depth` for transitive reach. This is the blast-radius question; hop counts tell you how direct the dependency is. - **"Where is symbol X?"** -> `search` (qualified-name aware, path-filterable). Faster and more precise than grep for symbol lookup; use grep when you want arbitrary text, comments, or strings. …

How to install
mdr add escoffier-labs/skillet/graphtrail@sha256:1ea9f000423636f2The line at the top of this page pins the label v0.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
