What problem does it solve? Keeping project documentation accurate is hard: READMEs drift from code, architecture descriptions go stale, and onboarding guides contradict actual behavior. This Skill performs a complete repository rescan and rebuilds an authoritative, evidence-grounded project guide so documentation always reflects the current code. ## Core Features & Use Cases - Full Repository Scan: Walks the entire repository with bounded exclusions, hashes every scanned file, and records a repository digest for provenance. - Evidence-Grounded Reporting: Inventories skills, prompts, agents, schemas, commands, features, and workflows, each backed by verified repository-relative evidence paths. - Atomic Dual Output: Publishes reports/project-understanding.json and reports/project-understanding.md as one atomic pair, preserving the last complete version if publication fails. - Use Case: After shipping a feature, run the scan to rebuild the contributor guide, then let downstream skills like project-video use the rebuilt JSON as the authoritative narration source. ## Quick Start Ask the agent to run the project-understanding scan from the repository root to rebuild the JSON and Markdown project guide.
