v0.12.4

What's new

• obsidian_archive_thread MCP tool — agents can now close out completed threads at the end of a session. Saves the vault note first (so history is preserved) then removes the thread from the active list. A thread cannot archive itself.
• Agent Dashboard footer layout — attach and mic buttons now appear in the bottom footer row, matching the conversation panel layout.
• Cleaner placeholders — removed ellipsis and keyboard hints from all message input boxes (Message Claude, Dispatch a task, Dispatch a new task).
