What problem does it solve? Codebases accumulate undocumented decisions, APIs, and data models, forcing teams to reverse-engineer intent from source. This Skill produces accurate documentation grounded in the actual code and conversation, eliminating guesswork and placeholder docs. ## Core Features & Use Cases - Multi-format documentation: Generates JSDoc, READMEs, ADRs, user guides, API references, and changelogs following established formats like Keep a Changelog. - Mermaid diagram generation: Creates flowcharts, sequence diagrams, ERDs, state diagrams, C4 diagrams, Gantt charts, and git graphs from real code structures. - Context-first workflow: Scans the conversation for signals (functions, decisions, schemas) and proposes a documentation plan before asking questions. - Use Case: After shipping an auth feature, ask it to document the work — it reads the implementation and produces a sequence diagram for the login flow, an ERD for the user model, an ADR for the token strategy, and a changelog entry. ## Quick Start Ask the agent to document the authentication flow you just built, including a sequence diagram and an ADR for the token storage decision.
