🤝 rails × marketplace

Ship marketplace on Ruby on Rails without losing weeks to compliance.

Ruby on Rails is a Ruby natural fit for marketplace. GreatCTO auto-detects both — adds the marketplace archetype overlay, wires marketplace-specific gates, and runs 34 specialist agents around your existing Ruby on Rails workflow.

$ npx great-cto init 🤝 See archetype →

What changes when GreatCTO joins your Ruby on Rails project

Detection → overlay → gates → reviewers.

1 · DETECT

Stack + archetype

GreatCTO reads your Gemfile and detects rails + marketplace archetype from signals: imports, file structure, env vars, README hints.

2 · OVERLAY

Archetype pack

Attaches the marketplace archetype overlay: archetype-specific reviewer + compliance gates. Override if your specifics differ; the defaults are sensible for Ruby on Rails-style projects.

3 · GATES

Ruby on Rails-aware reviewers

qa-engineer runs rubocop / rspec / brakeman; security-officer flags mass assignment + N+1 ORM queries; performance-engineer checks ActiveRecord query hot paths.

4 · MEMORY

Cross-project lessons

Bugs you've hit before in other Ruby on Rails projects (connection-pool exhaustion, ORM N+1 queries, retry storms) — the agent's Step 0 includes the prior detection order. MTTR drops 94 % on second occurrence (methodology).

⚐ gate:plan — your approval needed

Approve → 3 senior-devs run in parallel worktrees → 5 reviewers fan out in parallel → gate:ship → deploy. One real run walked stage-by-stage: /proof.
