Plan-and-Solve is a prompting technique where the model first writes an explicit plan, then follows the plan to reach an answer.
Why It Matters for Agents
Separating planning from execution reduces errors in multi-step problems: missing steps, premature tool calls, and inconsistent reasoning.
Plan-and-Solve vs Plan-and-Execute
- Plan-and-Solve is a prompting technique within a single model interaction.
- Plan-and-Execute is an architectural pattern that separates a planner from executors and treats the plan as an artifact.
