Agentic AI: separating planner and executor for clarity
One model writes the plan, another (or the same one in a different prompt) executes each step. Plans become reviewable artifacts.
11 min · Reviewed 2026
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
