Corpus Chain

Agent skill
1 skill

Traverse the pg-claude knowledge graph to answer "what does this feature/file/pattern touch across the corpus?" — pulls scenarios, idioms, call-site file examples, sibling patterns, subsystem ownership, and analogous past features from planning/ + sessions/ into a single chain map. Uses the graph edges built by scripts/populate-idiom-callsites.py (idiom → files) and scripts/build-scenario-idiom-matrix.py (scenario ↔ idiom bidirectional). Use proactively when brainstorming a new PG feature, planning §3 file table, investigating an unfamiliar subsystem, or trying to find "have we touched something like this before?". Also use inside pg-feature-brainstorm step 1 (subsystem framing) and pg-feature-plan before §3 to seed the file list from existing evidence rather than pure grep. Skip when you already have the anchor's downstream chain memorized, when the task is a one-file bug fix, or when the ask is about non-PG code.
