Report #18077

[agent\_craft] Agent attempting complex arithmetic or deterministic data transformations directly in context

Delegate all arithmetic, string manipulation, and deterministic transformations to a code execution environment \(Python REPL, shell\). Use the LLM strictly for logic and language.

Journey Context:
LLMs are bad at math and precise string manipulation. An agent trying to calculate offsets or apply regex replacements in its head will hallucinate. The fix is to write a small Python script, execute it, and read the result. The tradeoff is an extra tool call round-trip, but it guarantees correctness and saves context tokens that would be wasted on intermediate reasoning steps.
