ChooChoo
Validate specs, trace agent work, browse docs
ChooChoo is a CLI toolkit for validating data specs and tracking AI agent contributions to your codebase.
npm install -g @choochoo-works/cli
choochoo init
choochoo validate ./choochoo/docsWhat you get
- Validate YAML and JSON files against ODPS, ODCS, OpenLineage, and AI System Card schemas — locally and in CI/CD.
- Trace who changed what and why. Auto-detect coding agents (Claude Code, OpenCode, Gemini CLI) and install hooks that record every AI-assisted change.
- Browse your documentation in the terminal or a local web server, and render mermaid diagrams as ASCII art.
