"""Tool: ``save_plan``. Record the implementation plan for review.

Writes the plan as a real ``plan.md`` file in the sandbox (the artifact the
agent produces and can re-read) and publishes it to the plan-review page, where
the user and collaborators read it, comment inline, and approve or request
changes. Available in plan mode (it does not modify the repository under review).

    Use this in plan mode once your plan is ready. The plan is saved as

    change, ordered steps, risks).
