Important: Do not tick a checkbox if you haven’t performed its action. Honesty is indispensable for a smooth review process.

In the following questions <cask> is the token of the cask you're submitting.

After making any changes to a cask, existing or new, verify:

• The submission is for a stable version or documented exception.
• brew audit --cask --online <cask> is error-free.
• brew style --fix <cask> reports no offenses.

Additionally, if adding a new cask:

• Named the cask according to the token reference.
• Checked the cask was not already refused (add your cask's name to the end of the search field).
• brew audit --cask --new <cask> worked successfully.
• HOMEBREW_NO_INSTALL_FROM_API=1 brew install --cask <cask> worked successfully.
• brew uninstall --cask <cask> worked successfully.

Reason for change

The current cask kaku points to a deprecated music player (EragonJ/Kaku) that has not been maintained since 2021. This cask was deprecated on 2024-07-17 and will be disabled on 2025-07-17.

This PR replaces it with Kaku (https://github.com/tw93/Kaku), a modern macOS-native terminal emulator built for AI coding workflows. It's a fork of WezTerm, optimized for AI developers.

• Terminal emulator is a core developer tool with much higher utility
• The old music player has only ~24K downloads/year and is effectively abandoned
• The current token conflict causes confusion when users run brew upgrade kaku

Verification

• brew audit --cask --online kaku passes
• brew install --cask kaku installs correctly

@tw93 Disabled casks are not removed until 12 months after they have been disabled.
Can you please adjust the kaku token to be tw93-kaku for now, and after the current kaku cask has been removed a PR can be opened to change it then.

Please also ensure you keep the Pull Request Template in tact when opening PRs in Homebrew, as it provides important steps for a successful PR - https://raw.githubusercontent.com/Homebrew/homebrew-cask/refs/heads/main/.github/PULL_REQUEST_TEMPLATE.md - I have updated the PR body for you to fill it out before we move forward.

Ps. On a personal note, thank you for your work on your other applications like mole and pake. Happy user and sponsor here :)

@khipp Thanks for the clarification and for using my other tools! 🙏

I understand the policy now. I'll proceed with kakuku as the token for now - it's already set up in my tap and working well for users.

My plan:

1. Submit the PR with kakuku token once it's stable
2. After the current kaku cask is fully removed from homebrew-cask (12 months after disablement), I'll open a new PR to rename it to kaku

This approach avoids any conflicts and gives users immediate access via brew install tw93/tap/kakuku today, with a clean path to the shorter name in the future.

I'll make sure to fill out the PR template completely. Thanks again for maintaining Homebrew!
