Report #83534

[agent\_craft] Agent tries to solve complex algorithmic problems or precise calculations by loading code into context and reasoning about it

Externalize deterministic operations to code execution \(e.g., Python REPL\) rather than trying to reason the output in context. Use context only for understanding what to compute, not how to compute it step-by-step.

Journey Context:
Agents often try to 'simulate' code execution in their context window to predict an output. This inevitably leads to arithmetic errors, hallucinated variable states, and logic bugs. The tradeoff is that executing code takes an extra tool call round-trip, but the accuracy gain is massive. Context is for semantic reasoning and planning; code execution is for deterministic calculation. Never trust an LLM to trace code execution in its head.
