Set up conventions

A prompt-driven setup, not a script. Explore, present what was found, confirm, then write. Nothing is committed, pushed or imported without its own go-ahead (ASK-1, ASK-2, ASK-3).

1. Explore

Read what exists; assume nothing (EVID-8):

• git remote -v: which forge, which repository.
• AGENTS.md and CLAUDE.md at the root: which exists, whether a "Rules that bind" block is already there.
• docs/agents/, .agentic-sdlc.json, GLOSSARY.md, docs/adr/, .scratch/.
• .github/workflows/: an existing CI gate the ruleset should require.
• Rulesets and branch protection already applied (gh ruleset list on GitHub; the protected branches of the project on GitLab).
• Monorepo signals: a workspace file, several packages with their own source.

2. Present and confirm
