What problem does it solve? Completed marketing sites often ship without documentation, leaving future developers and AI agents without context on architecture decisions, build pipelines, and deployment workflows. This Skill analyzes the actual codebase and writes accurate project documentation instead of placeholder templates. ## Core Features & Use Cases - Codebase Analysis: Reads package.json, routing files, Firebase configs, env files, and build scripts to extract real project values. - Three-File Generation: Produces AGENTS.md (comprehensive agent context), CLAUDE.md (pointer to AGENTS.md), and README.md (human-facing overview with scripts table and quick start). - Framework Detection: Detects Vite vs Next.js tracks via .site-framework.json and documents the correct architectural rules for each (hydrateRoot and prerendering vs server components and App Hosting). - Use Case: After finishing a Firebase-hosted marketing site, run this Skill to generate documentation that captures the three-file routing rule, environment variables, and deploy commands so the next contributor avoids known traps. ## Quick Start Ask the AI to generate AGENTS.md, CLAUDE.md, and README.md documentation for the completed site in the current project directory.
