My package provides an interface to the google Gemini CLI directly within Sublime Text. It uses the agentclientprotocol to communicate with the Gemini CLI and sends prompt instructions. The plugin implemented a custom-designed Chat View, eliminating the need for users to install any terminal plugin. The use can click the phantom buttons in char view to response to some permission request.

The plugin add context menu of Chat with Gemini which can send current context(file name, lines) to chat. Much like copilot, this solution is far more easy to use.

The plugin add keybinding for start gemini chat. User can also disable this and use command palette to open it.
