Refactor Safely

Plan a refactor from the dependency graph and apply renames from a preview.

Steps

1. Call refactor_tool with mode="suggest" for refactoring candidates, or mode="dead_code" for unreferenced code.
2. For a rename, call refactor_tool with mode="rename", old_name and new_name. Check the returned edit list before applying.
3. Call apply_refactor_tool with the returned refactor_id to apply the rename.
4. Before a large refactor, call get_impact_radius_tool and get_affected_flows_tool to see the dependents and critical paths involved.
5. Call find_large_functions_tool to find functions worth splitting.
6. After the change, call detect_changes_tool to confirm the impact matches the plan.

Token Efficiency Rules

• Call get_minimal_context_tool(task="<your task>") before any other graph tool.
• Pass detail_level="minimal" wherever a tool accepts it. Use "standard" only when minimal is not enough.
• Prefer a targeted query_graph_tool call over a broad listing call.
• Budget: about five tool calls and 800 tokens of graph output per task.
• Read the implementation and its tests before changing code. The graph narrows scope; it does not replace the source.
