M2 — Module-Shape Selection (CoT / ReAct / PoT / Predict)

"Pick the lowest-power Module that works. Default to ChainOfThought." — DSPy docs [dspy.ai/learn/programming/modules/]

This overlay sharpens that line into a rubric: the default is not a law. The shape is a function of the task structure, and CoT is only one of four answers.

This is an enhancement overlay. It assumes the [[dspy]] library skill is loaded (it provides dspy.Predict, dspy.ChainOfThought, dspy.ReAct, dspy.ProgramOfThought APIs and install). This file adds only the decision the lib skill leaves implicit. Cross-link: [[dspy]], and the optimizer SOP [[agentsop-dspy]].
