Report #62939

[agent\_craft] Agent attempts complex arithmetic or multi-step logical deductions directly in text generation

Always externalize mathematical calculations, date manipulations, and strict logical evaluations to a Python code execution tool, even if the LLM 'knows' the math.

Journey Context:
LLMs are next-token predictors, not calculators. While they can do simple addition, complex math \(e.g., calculating time deltas, floating point arithmetic, or large permutations\) will hallucinate. Loading the numbers into context and asking for the answer is a fundamental context engineering error: you are using the wrong compute substrate. The fix is to force tool use for math. The tradeoff is latency \(running a Python interpreter takes a second\), but correctness is non-negotiable for logic.
