Report #12126
[agent\_craft] agent hallucinates math or string manipulation
Externalize deterministic operations to a code execution environment \(e.g., Python REPL\). The agent should write a script, execute it, and read stdout, rather than computing the answer in its context.
Journey Context:
LLMs are probabilistic reasoners, not calculators. While CoT helps with logic, arithmetic and precise string manipulation are failure points. Writing a script takes an extra turn but guarantees correctness for deterministic tasks, saving multiple debugging turns later. Trust the LLM for logic; trust the runtime for computation.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
