Report #79579

[agent\_craft] Agent uses LLM reasoning for deterministic tasks \(e.g., string manipulation, math, sorting\) and wastes tokens or hallucinates

Externalize deterministic logic to code execution \(e.g., Python REPL, bash scripts\) rather than asking the LLM to compute it in context. Use the LLM for \*routing\* and \*orchestration\*, not calculation.

Journey Context:
LLMs are bad at arithmetic and complex string manipulation. An agent that tries to calculate offsets or parse JSON manually in its chain-of-thought will eventually fail and waste tokens. The fix is to write a small script, execute it, and read the stdout. The tradeoff is an extra tool call round-trip, but the correctness and token savings are overwhelmingly worth it for any non-trivial deterministic operation.
