Orchestrates the full Rails project setup from context gathering through CI/CD configuration.
rails new or existing repo clone)Load project context first:
Inline fallback (if sub-skills are unavailable):
# Verify Ruby version matches .ruby-version
ruby -v
# Install dependencies
bundle install
# Check database connectivity
rails db:create db:migrate
# Confirm test runner is operational
bundle exec rspec --dry-run
# Load env vars (copy example if missing)
cp .env.example .env 2>/dev/null || trueHARD GATE — Environment Check:
.ruby-version)config/credentials.yml.enc or .env)If environment check FAILS: Fix the failing item above before proceeding to Phase 2.
Proceed only after environment check passes.
CI/CD Proposal Checkpoint — Decide on pipeline approach:
Configure CI pipeline (linting, testing, security, migrations):

# Rollback: re-run previous deployment job or use platform CLIVerify everything works end-to-end:
# Local development
bundle install
rails db:create db:migrate
rails server # Should start without errors
bundle exec rspec # Should run (even if 0 tests)
# CI simulation (if possible locally)
act push # GitHub Actions local runner (optional)Setup Checklist: Marked file SETUP_CHECKLIST.md with:
| Predecessor | This Skill | Successor |
