Report #6324

[agent\_craft] Agent attempts complex mathematical calculations or deterministic data transformations in-context using chain-of-thought, leading to hallucinated or incorrect results

Externalize deterministic operations to code execution tools \(e.g., Python REPL, shell commands\). The agent should write the script, execute it, and read the result, rather than computing it in its latent space.

Journey Context:
LLMs are next-token predictors, not calculators or deterministic state machines. While chain-of-thought helps with reasoning, it fails for precise arithmetic, complex string manipulation, or applying exact business rules. The agent will confidently output wrong numbers or malformed strings. Externalizing to a code execution environment guarantees correctness and provides an auditable artifact. The tradeoff is latency \(an extra tool call\) and the need for a sandbox, but for coding agents, the sandbox is already the target environment.
