product-capability

To turn a vague PRD into an implementation-ready plan, extract product invariants, interfaces, and states to form a capability contract. This surfaces implicit business rules and defines explicit constraints, non-goals, and observability needs for engineering teams.

A capability contract is a structured plan defining actors, surfaces, state transitions, and open questions for a feature. You need one during product planning when cross-functional requests require a durable shared understanding across multiple services.

Extract business rules and invariants from founder notes by identifying implicit trust boundaries, rollout needs, and policy limits. This process surfaces hidden constraints and translates them into an implementation-ready capability plan without inventing product truth.

Yes, you can use capability contract extraction for cross-service feature requests and roadmap items. It defines data implications and interfaces required for multi-service features, ensuring engineering teams align on what must be true before building starts.

The best way to align engineering teams before coding is generating a capability contract that defines non-goals, observability needs, and open questions. This converts product intent into a structured plan, preventing misalignment during cross-team implementation.
