Two tools with clear naming (get_pending_action, execute_pending_action) and good descriptions (100+ chars each). Both have minimal input schemas (single string parameter). Descriptions explain state transitions and approval workflow well. However, output schemas are not documented in the visible code, the tool definitions show only input parameters. No parameter descriptions visible in the schema definitions. Error handling is mentioned in descriptions but not formalized. Risk annotations (READ_ONLY, IRREVERSIBLE) are present but not mapped to MCP tool annotations.

• Document output schemas for both tools. Specify that get_pending_action returns {state: string, preview: string, expires: datetime} and execute_pending_action returns {success: boolean, executed_at: datetime}.
• Add 'description' field to the pending_action_id parameter schema: 'The unique identifier of the pending action to check or execute (returned by prior high-risk operations)'.
• Map risk annotations to MCP tool hints: register get_pending_action with readOnlyHint=true and execute_pending_action with destructiveHint=true.
• Formalize error responses with actionable guidance. E.g., 'Action expired. Pending actions are valid for 24 hours. Request a new approval from the operator.' instead of a bare error.
• Consider adding a dry_run parameter to execute_pending_action or a separate preview_execution tool to let agents confirm the action before committing.
