## Summary
- Move build/env/DB setup out of the GitHub Actions workflow into an
on-demand script (`packages/twenty-utils/setup-dev-env.sh`) that Claude
invokes only when needed
- Add Nx/build cache restore/save steps to speed up repeated runs
- Add `allowed_tools` so Claude can run the setup script and common dev
commands (nx, jest, yarn)
- Add `PG_DATABASE_URL` env var via `settings` for the postgres MCP
server
- Remove unnecessary `actions: read` permission grant
- Document the lazy setup pattern in CLAUDE.md
This makes read-only tasks (code review, architecture questions, docs)
fast by skipping the ~2min build/setup overhead, while still letting
Claude run tests and builds when it needs to.
## Test plan
- [ ] Comment `@claude what is the architecture of the backend?` —
should answer fast without running setup
- [ ] Comment `@claude run the twenty-server unit tests` — should call
setup script first, then run tests
- [ ] Verify cross-repo dispatch still works
