Module modes 

claude-code-mode — the minor mode layered on the IDE terminal buffer.

I1 registers it as a Manual-activation marker mode (no per-buffer resources). In I5 it becomes the minor mode :claude activates on the BufferKind::Terminal buffer running the agent: its on_activate will ensure the server is running, contribute the headerline status row, and own the diff affordances (design §3). The -mode suffix matches the ModeRegistry naming convention (enforced at registration).

Structs

ClaudeCodeMode

The Claude Code IDE minor mode.

ClaudeCodeStatusGuard

I7: per-activation Guard. While claude-code-mode is active on a buffer, that buffer shows the claude-code modeline status segment; the Guard’s Drop (on deactivate / buffer close) unregisters it so the segment clears. None when the server handle wasn’t available at activation (e.g. tests without the service) — then the Guard is an inert no-op.
