WHAT IT DOES

What save_plan does on Software Planning Tool

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

WHY IT NEEDS A POLICY

Why save_plan needs a policy

This tool creates or modifies stored planning data. It is reversible—plans can be updated, deleted, or overwritten later. There is no data destruction, code execution, or financial impact. The operation is a standard write/storage action typical of project management systems. The blast radius if misused is low since it only affects project planning documents, not code, infrastructure, or critical systems.

From the tool's definition Tool name 'save_plan' and description 'Save the current implementation plan' indicate creating or persisting data (the plan) in a reversible manner.
