Report #6030

[agent\_craft] Agent attempts complex arithmetic, sorting, or multi-step data transformations in-context and fails silently

Externalize deterministic logic. If a task requires sorting a list, calculating diffs, or parsing large JSON structures, write a Python script, execute it via a tool, and read the stdout. Never do math or complex data manipulation in the LLM's latent space.

Journey Context:
LLMs are next-token predictors, not calculators. When asked to 'sort this list of 20 items by date' or 'calculate the difference between these two timestamps,' they frequently make mistakes. Agents often try to do this in-context to 'save' a tool call, but this leads to cascading errors. The cost of a code execution tool call is vastly lower than the cost of a hallucinated sort order that breaks the downstream logic.
