Tablekeeper combines a reusable software factory with the restaurant reservation system it produced. Five agents in Band Desktop handle planning, coordination, frontend development, backend development and independent QA. All use Codex with gpt-6-astra at medium reasoning effort, following a review-and-repair workflow. The website lets diners search availability, book individual or combined tables, and manage reservations. The service also supports booking policies, recurring reservations and seating adjustments after table closures. Atomic operations and safe retries protect against conflicting or duplicate bookings. The team completed all four stages in about two hours. The final stage passed 158 applicable supplied tests, with estimated model spend of $29.68. The repository includes the application, reusable agent mandates, startup instructions and collaboration log.
