What problem does it solve? Writing decision-grade workflow documents (PRDs, design docs, implementation plans, ADRs, roadmaps, RCAs) is slow and inconsistent, often producing walls of text that downstream agents and reviewers cannot act on. This Skill standardizes doc authoring with fixed templates, evidence standards, and required diagrams so documents are reviewable and executable. ## Core Features & Use Cases - Template-driven authoring: Six ready templates covering PRD, design doc/RFC, technical plan, ADR, roadmap, and RCA, each with fixed sections for goals, non-goals, tradeoffs, and acceptance criteria. - Diagram-first documentation: Enforces Mermaid and Graphviz/DOT diagrams for flows, dependencies, timelines, and causal chains, with required interpretation notes. - Quality gates and standards: A standards reference defines document selection, SPADE decision framing, evidence confidence labels, review checklists, and anti-patterns. - Use Case: After an incident, ask the agent to produce an RCA. It loads the RCA template, builds a timeline and causal Graphviz diagram, records confirmed root cause and ruled-out hypotheses, and lists prevention actions with owners. ## Quick Start Use the structured-doc-authoring skill to write a design doc for the new caching layer, including a Mermaid sequence diagram, alternatives considered, and a rollout plan.
