Build cmux changes without disrupting live sessions.
Guides cmux contributors through native setup, isolated development builds, project-file maintenance, and sidebar extension verification.
When to use it
Use when setting up cmux, changing native build inputs or Xcode project files, verifying tagged builds, or developing sidebar extensions.
It changes how the agent sets up, builds, and verifies cmux changes by requiring scoped checks and isolated tagged native builds.
What you provide
Requires Python 3 to run the repository's local verification command.
Native app work needs the Xcode major pinned in .xcode-version; the Intel/macOS 14 fallback uses Xcode 16.2 with Swift 6.0.
