Hexis
Git-backed skills, tools & context for AI agents
Hexis is the open-source core of Bevel, a vendor-agnostic control plane that defines a company's AI agents — their context, skills, tools and permissions — as files the company owns in its own git infrastructure rather than inside a vendor's dashboard. Skills are markdown procedures, tools are manifests with vault-managed secrets, and every agent gets its own identity rather than sharing one service account. Connects to any agent through MCP servers.

Who it's for

When not to use it
Overkill for a solo developer on one machine — a plain git repo does the same job with no platform.
