Report #12678

[agent\_craft] Agent attempts complex arithmetic, sorting, or large-scale text manipulation purely through in-context reasoning, leading to hallucinations and errors

If a task requires deterministic computation, iterating over >20 items, or precise string manipulation, externalize it to a code execution tool \(e.g., Python REPL\) rather than doing it in-context.

Journey Context:
LLMs are bad at math and precise logic. While in-context reasoning is fast for simple tasks, any operation that would fail without a calculator or script should be delegated to a code interpreter. The tradeoff is an extra tool call round-trip, but the accuracy gain from deterministic execution vastly outweighs the latency penalty for logic-heavy tasks.
