Section 1
The premise
Agents that plan and execute in one pass are hard to audit because the plan exists only in the model's head. Separating the steps creates a written plan you can review, edit, or replay.
What AI does well here
- Produce a numbered plan when asked for one before action
- Execute a plan step-by-step when the plan is fixed
- Mark steps complete with results
What AI cannot do
- Self-correct an unreviewed plan that was wrong from the start
- Ensure the executor matches the planner's intent without checks
- Adapt the plan mid-execution without explicit replanning
