AI coding agents now have AGENTS.md, memory banks, harnesses, evals, and monitors. They still lack product context: what the product promises to do and which behaviors must stay true.
When an outsourcing engagement wraps up, product knowledge walks out the door. A living product contract keeps it in the codebase — not in someone's head.
AI can now extract product logic from your codebase. Stewie builds a living product contract your whole team can read — no code, no stale docs, no waiting on engineers.
PMs confirm behaviors. BAs clarify domain logic. QA knows what to protect. New hires onboard in hours. Vendor teams skip the reverse-engineering phase. Here's how each role contributes to a living product contract.
Strategic leaders shouldn't need three meetings to verify whether a product decision was implemented correctly. A living product contract gives you a direct line to what's running in production.
