What problem does it solve? Product intent from PRDs, roadmap notes, or founder discussions often stays implicit, forcing engineers to rediscover hidden constraints mid-implementation. This Skill turns that intent into an explicit, durable capability contract before multi-service work 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 Extraction: Surfaces business rules, invariants, trust boundaries, data ownership, lifecycle transitions, and rollout requirements that usually live only in senior-engineer memory. - SRS-Style Contract: Produces an implementation-facing plan with actors, surfaces, states, interfaces, data implications, non-goals, and open questions, ending with a clear handoff decision. - Use Case: A cross-repo feature request arrives with only a PRD paragraph. Use this Skill to generate a capability manifest that exposes fixed policy, architecture preferences, and unresolved decisions before any code is written. ## Quick Start Use the product-capability skill to turn this PRD into an implementation-ready capability plan with constraints, non-goals, and open questions.
