The new tap

Cirrus Labs announced on April 7, 2026 that it's joining OpenAI's Agent Infrastructure team. That's why the Homebrew formula moved from cirruslabs/cli to openai/tools.

The new install path adds the OpenAI tap and trusts both formulae:

brew tap openai/tools
brew trust --formula openai/tools/tart
brew trust --formula openai/tools/softnet
brew install openai/tools/tart
