Open-source tools for AI agents
Tools for teams building with AI agents.
Find the skills your teams keep rebuilding, review what they can do, share the good ones.
Works with Claude Code, Codex, Cursor, GitHub Copilot, Gemini and MCP
What we’re building
Keep the skills that work. Retire the rest.
Teams everywhere are writing the same agent skills, rules and MCP configs, in every repo and for every tool, and nobody checks what they’re allowed to do. We’re building the tools to see them, review them and share the good ones, in the open.
See what actually runs
Usage for every skill, across every repo and every tool.
Improve what works
Make the best version of each skill the default.
Retire what doesn’t
Deprecate stale skills and stop spending tokens on them.
Review before you trust
See what each skill is allowed to do before it spreads.
Why a raven
Named for Huginn.
In Norse myth, Odin sends the raven Huginn, whose name means thought, out across the world each day. It comes back at night with what it learned.
That’s the job: go out across every repo and tool, and come back with what your teams have learned. The amber full stop in our name is the raven’s eye: the moment a thought lands.
