What problem does it solve? Brownfield projects often lack documentation that AI agents and new developers need to understand the existing system. This Skill scans an existing codebase and produces a complete, structured documentation set (architecture, API contracts, data models, source tree, development guides) ready for brownfield PRD planning. ## Core Features & Use Cases - Three Scan Levels: Choose quick (pattern-based), deep (critical directories), or exhaustive (every source file) analysis depending on time and depth needs. - Multi-Part Project Support: Detects monorepos and client/server structures, documenting each part separately plus an integration architecture document. - Deep-Dive Mode: Performs exhaustive file-by-file analysis of a specific folder, feature, or API group, producing dependency graphs, data flow traces, and modification guidance. - Resumable State Tracking: Maintains a project-scan-report.json state file so interrupted scans can resume within 24 hours. - Use Case: Point it at a legacy Next.js e-commerce repository and receive an index.md, architecture.md, api-contracts.md, data-models.md, and development-guide.md that an AI agent can use to plan new features. ## Quick Start Ask the AI to document this project and choose a scan level when prompted.
