What daily_create does on Mcp Obsidian Planner

WHY IT NEEDS A POLICY

Why daily_create needs a policy

The tool creates new daily notes in the Obsidian vault, which is a reversible write operation. It does not execute arbitrary code, delete data, or affect financial systems. The 'Returns existing note if already created' behavior indicates idempotency and no destructive side effects. Severity is low because creating templated notes in a personal planning system has minimal blast radius even if invoked unintentionally.

From the tool's definition Tool description states 'Create a daily note from template', which is a create operation that modifies the vault by adding new notes.
