"""Obsidian loop capability — agentic retrieval & authoring over a live vault.
|
|
|
|
Active whenever the user's selected knowledge base is a connected Obsidian
|
|
vault (resolved by :mod:`deeptutor.capabilities.obsidian.binding`). As a
|
|
:class:`KnowledgeCapability` it owns the turn: the chat loop runs exclusively
|
|
on the nine Obsidian tools (plus the ``ask_user`` floor), navigating and
|
|
editing the vault's Markdown directly rather than retrieving flattened chunks.
|
|
|
|
The vault root is injected into each tool call as ``_vault_path`` server-side;
|
|
the model never supplies it.
