I didn't find a tool that supported the desired functionality, so I built what I personally wanted and needed.
Intended use cases - access my own private and public AGENETS.md and Agent Skills - access my company's AGENETS.md and Agent Skills - access open source AGENETS.md and Agent Skills - toggle parts of AGENTS.md on/off per the codebase I'm working in - easily work with files from local file system and github - agentic assets are version locked in a manifest file
