[agent\_craft] Agent produces incorrect numerical calculations or logic errors when reasoning in natural language instead of executable code

Use Program-of-Thoughts \(PoT\) for numerical, symbolic, or logical reasoning: force the model to generate executable Python/DSL code inside backticks to solve the sub-problem, then execute it externally to get the result. Only use Chain-of-Thought \(CoT\) natural language for qualitative reasoning \(e.g., design decisions\). Never allow the model to perform arithmetic or sorting in prose; always externalize computation to an interpreter.

Journey Context:
LLMs are poor at arithmetic and symbolic logic in free text \(e.g., counting letters in a word, large number addition, boolean algebra\). CoT encourages step-by-step English reasoning which compounds calculation errors \(e.g., carrying errors in addition\). PoT offloads the computation to a deterministic interpreter, using the LLM only for program synthesis. Common mistake: allowing the model to write 'The answer is 42' based on its own calculation without verification, or generating code but not executing it \(treating the code as decoration\). The journey involves recognizing that for agents, 'reasoning' should mean 'writing code to reason', not 'talking through it'. By constraining the model to generate executable programs for any step involving counting, sorting, arithmetic, or set operations, you eliminate hallucinated intermediate values and ensure verifiable reasoning traces. This is distinct from CoT which is only safe for subjective or creative tasks.
