 # CoDev Code
 
-The AI coding agent of the CoDev ecosystem, invoked as `codev code` through the CoDev CLI.
+The AI coding agent of the CoDev ecosystem. The [codev](https://github.com/quickbeard/codev) hub CLI dispatches to it directly: bare `codev` opens the agent, and any command the hub doesn't claim (`codev run "..."`, `codev serve`, `codev models`, …) is passed through. The installed binary itself is named `codev-code`.
 
 CoDev Code is a fork of [opencode](https://github.com/anomalyco/opencode) that tracks upstream while carrying a small set of organization-specific changes. Read [DIVERGENCES.md](DIVERGENCES.md) before editing any upstream file — it defines where changes are allowed to live.
