01 — The unit
What a pack is
A pack is one set of rules, written out for the four places agents already look. Cursor reads an .mdc rule, Claude Code reads CLAUDE.md, a wide set of agents read AGENTS.md, and GitHub Copilot reads .github/copilot-instructions.md. Same advice, four paths.
02 — Catalog
4 packs

03 — Use it
How it works
01
Pick a pack
Choose the stack you are actually in. The starter pack is the safety rail for everything else.
02
Copy or download
Copy one file, or download a zip. Format zips and the full pack already use the path that tool expects.
03
Drop it in the repo
Commit the files. The next agent session reads them from the usual place.
