Docs / Using Prism

Understand a repo

Orient to an unfamiliar repository with DNA, stack, and landmarks.

Learn what a repository is built from and where to start reading.

cd your-repo
prism doctor
prism overview

What you get back

  • DNA / stack — frameworks, domains (frontend, backend, data, infrastructure), confidence and evidence per signal.
  • Landmarks — entrypoints and anchors a human would open first.
  • Graph — use graph (mode neighbors or explain) to walk outward from a landmark.

When this is wrong

  • Doctor chose the wrong workspace → pass --workspace or set PRISM_WORKSPACE.
  • Low-confidence stack signals (dependency only) are leftovers, not active tooling — check the evidence.
  • Odd file counts → excludes or generated output; see troubleshooting.
