Report #21575
[agent\_craft] Agent attempts to parse or transform large datasets directly in context, leading to hallucination or token exhaustion
Route data transformation tasks to a Python execution sandbox. The agent should write a script to process the data, execute it, and only return the final summary or result to the LLM context.
Journey Context:
LLMs are bad at deterministic, large-scale data manipulation. Trying to read a 10,000-row CSV into context to find the mean of a column will fail or hallucinate. The tradeoff is an extra tool call cycle \(write script -> execute -> read output\), but it guarantees correctness and saves massive context space. The agent's context is for reasoning, not for acting as a database.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
