WHAT IT DOES

What task_add does on Mcp Obsidian Planner

WHY IT NEEDS A POLICY

Why task_add needs a policy

This tool creates a new task entry, which is a reversible write operation. It does not execute arbitrary code, delete data, move money, or trigger external operations with unpredictable effects. Severity is medium because an AI agent could add spurious or misleading tasks that clutter the task system, but the impact is bounded to the note structure and recoverable.

From the tool's definition Tool name 'task_add' and description 'Add a new task to a note in the Tareas section' indicate creation of new data without deletion or modification of existing records.
