Returns the raw markdown body content under the targeted heading.
AI agents call get_heading_contents to retrieve information from Obsidian Modified without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that queries and retrieves markdown content from a note without any side effects. It does not create, modify, delete, or execute anything. The severity is low because reading note content poses minimal risk; the primary concern would be information disclosure, which is limited to data the user already has access to within their own Obsidian vault.
From the tool's definition Tool name 'get_heading_contents' and description 'Returns the raw markdown body content under the targeted heading' indicate retrieval of existing data with no modification, deletion, or execution.
