What problem does it solve? Product intent from PRDs, roadmap notes, or founder discussions often leaves engineering constraints implicit, causing senior engineers to repeatedly restate hidden assumptions during review. This Skill turns vague product asks into an explicit, durable capability contract before multi-service implementation begins. ## Core Features & Use Cases - Capability Restatement: Compresses a product ask into one precise statement covering the user, the new capability, and the outcome change. - Constraint Resolution: Extracts business rules, invariants, trust boundaries, data ownership, lifecycle transitions, and rollout requirements that usually live only in senior-engineer memory. - SRS-Style Contract: Produces a structured implementation contract with actors, surfaces, states, interfaces, data model implications, policy constraints, and open questions. - Use Case: A founder shares a roadmap note for a booking feature spanning multiple services. Use this Skill to produce a capability manifest that exposes fixed policies, unresolved decisions, and a clear handoff before any coding starts. ## Quick Start Use the product-capability skill to turn this PRD into an implementation-ready capability plan with constraints, non-goals, and open questions.
