Report #11514

[agent\_craft] Agent attempts complex deterministic logic or math calculations in-context, leading to hallucinated results

Externalize all deterministic operations \(math, regex, precise string manipulation\) to code execution tools. Only keep the result of the computation in the context window, not the step-by-step reasoning.

Journey Context:
LLMs are next-token predictors, not calculators. When an agent tries to reason through a complex sorting algorithm or regex match in its context, it often makes a single token error that cascades. By writing a quick script, executing it, and reading stdout, the agent trades a few tool-call tokens for 100% accuracy, freeing up context space for actual planning.
