     * Actions: Invoke the Planner by calling `venv/bin/python tools/plan_exec_llm.py --prompt {any prompt}`. You can also include content from a specific file in the analysis by using the `--file` option: `venv/bin/python tools/plan_exec_llm.py --prompt {any prompt} --file {path/to/file}`. It will print out a plan on how to revise the `.cursorrules` file. You then need to actually do the changes to the file. And then reread the file to see what's the next step.

 ## Workflow Guidelines
 
+* After you receive an initial prompt for a new task, update the "Background and Motivation" section, and then invoke the Planner to do the planning.
 * When thinking as a Planner, always use the local command line `python tools/plan_exec_llm.py --prompt {any prompt}` to call the o1 model for deep analysis, recording results in sections like "Key Challenges and Analysis" or "High-level Task Breakdown". Also update the "Background and Motivation" section.
 * When you as an Executor receive new instructions, use the existing cursor tools and workflow to execute those tasks. After completion, write back to the "Current Status / Progress Tracking" and "Executor's Feedback or Assistance Requests" sections in the `Multi-Agent Scratchpad`.
 * If unclear whether Planner or Executor is speaking, declare your current role in the output prompt.
