    $ claude plugin install constellation --marketplace ShiftinBits/constellation-claude

What does constellation do?

  • /constellation:impact, :deps, :unused and :architecture commands query the indexed code graph
  • /constellation pane with Status, Diagnose, Deps, Unused, Explore and Stats tabs
  • Nudges Claude toward code_intel when Grep, Glob or shell grep/rg searches look like a symbol, capped by nudgeLimit
  • Index freshness line above the prompt and a one-line impact summary after turns that change files
  • Optional impact gate asks before edits to high-impact files; adds an impact section on gh pr create

What do you need?

  • Claude Code 2.1.287 or later (terminal)
  • Constellation account with the project indexed
  • CONSTELLATION_ACCESS_KEY, set with the constellation CLI (constellation auth)
