What problem does it solve? Turning agreed specifications and requirements into a clear, reviewable design document is time-consuming, and important design decisions, risks, and open questions are often left undocumented. This Skill produces a well-structured Japanese Design Doc that readers can review and give feedback on without extra explanation. ## Core Features & Use Cases - Structured Design Doc Generation: Creates documents with standard sections such as Objective, Background, Goals, Non-Goals, Scenarios, Security, and Open Issues, following project templates when they exist. - Cost-of-Being-Wrong Prioritization: Adjusts the depth of each design decision based on how expensive a mistake would be, asking the user about high-stakes choices and filling in reasonable defaults for low-stakes ones. - Gap and Risk Review: Uses the section catalog as a checklist to surface missing considerations, unresolved issues, and security/privacy/legal concerns. - Use Case: When you have settled on a feature specification, ask for a Design Doc and receive a complete Japanese document with measurable SLOs, threat scenarios, alternatives considered, and open issues ready for team review. ## Quick Start Use the design-doc skill to write a Design Doc in Japanese for the caching layer feature we just specified.
