WHAT IT DOES

What append_replan_note does on Keshro MCP

AI agents use append_replan_note to create or update resources in Keshro MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Keshro MCP environment.

WHY IT NEEDS A POLICY

Why append_replan_note needs a policy

The tool appears to modify planning notes/metadata within a project management system. This is a reversible write operation on structured data (plans, tasks, notes) rather than executing code, deleting data, or moving funds. The empty description limits confidence, but the naming pattern and context of sibling tools strongly suggest it appends data to a note field.

From the tool's definition Tool name 'append_replan_note' indicates appending/adding notes to a replanning context. Sibling tools like 'append_task_note', 'edit_task', 'add_task' are all Write operations that modify plan/task state.
