WHY IT NEEDS A POLICY

Why init_plan_knowledge needs a policy

This tool creates a new markdown file in a project directory. File creation is a Write operation (reversible via deletion). The severity is medium because creating files can affect project state and downstream processes, but the action is not destructive (file can be deleted) nor does it execute arbitrary code or move money. Confidence is high due to explicit 'Create' language in the description.

From the tool's definition Tool description states 'Create PLAN_PROJECT_ROOT/plan-knowledge.md from a starter' — the verb 'Create' indicates file creation, a reversible write operation.
