Tool Permissions
When the companion invokes a tool that requires approval (bash, file write, file edit), a permission prompt appears:- Allow Once: permits this single invocation
- Allow Session: permits this tool for the rest of the session
- Deny: rejects and tells the companion it was denied
Context Compaction
When the conversation fills the model’s context window, Grind automatically summarizes older messages into a compact summary. You’ll see a notice when compaction occurs. Manual compaction is available via/compact.
Image Attachments
Attach images to messages by pasting them or using the image attach shortcut. The companion can analyze images using vision-capable models (Claude, GPT-4o, Gemini).Sessions
Conversations are persisted to the vault (conversations and messages tables). Use /sessions to browse past conversations and /new to start fresh while keeping history accessible.
