Sublime Text integration

The reference implementation of TermMate, bringing agentic coding to the fastest editor.

Features

Native EditView — the chat interface uses Sublime’s native text components for extreme speed, REPL responsiveness, and familiar keyboard behaviour.
Multi-Agent Support — seamlessly switch between Claude Code, Codex, OpenCode, and Pi Agent.
File Changes Artifact & Inline Diffs — summary of edited files with line statistics (+ and -), inline foldable diffs, and double-click navigation.
Smart @ Cascading Completion — drill down through folders, workspace files, multi-root projects, and open tabs with auto-cascading navigation.
Split Chat Window & Dedicated Pane — isolate the chat into its own pane without files overwriting it (dedicated_chat_pane).
Plan Mode & Approve Mode — toggle between Fast and Planning modes, and configure tool permission policies (default, allow-edit, accept-all).
Session Management — start fresh, resume prior conversations, or rewind and branch from any prompt.
