zk_get_note
AI agents call zk_get_note to retrieve information from Zettelkasten without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The `get_` prefix and the presence of destructive (`zk_delete_note`), write (`zk_create_note`), and read-only peers (`zk_list_notes_by_date`, `zk_find_linked_notes`) strongly indicate this is a query/retrieval tool with no side effects. No data is created, modified, or deleted. Confidence is slightly below maximum only because the description is empty, requiring reliance on naming convention and server context.
From the tool's definition Tool name is `zk_get_note` which follows a retrieval pattern (get). Sibling tools show this server provides note management; `zk_get_note` clearly retrieves an individual note without modifying it, consistent with read operations like `zk_find_similar_notes`,…
