What problem does it solve? Brownfield projects often lack up-to-date documentation, making it hard for developers and AI agents to understand the codebase before planning new features. This Skill scans an existing project and produces a complete documentation set (index, architecture, source tree, development guide, API contracts, data models) ready for brownfield PRD workflows. ## Core Features & Use Cases - Three Scan Levels: Choose quick (pattern-based, no source reading), deep (critical directories), or exhaustive (all source files) analysis depending on time and depth needs. - Resumable State Tracking: A project-scan-report.json state file records progress after every step, allowing interrupted runs to resume within 24 hours. - Deep-Dive Mode: Exhaustively documents a single folder, feature, or API group with full file inventories, dependency graphs, and data flow analysis. - Use Case: Point the workflow at a legacy repository with no docs; it detects the project type from manifest files, classifies the stack, and writes index.md, architecture.md, and development-guide.md to the output folder. ## Quick Start Ask the AI to document this project and choose a quick scan to generate the initial documentation set.
