Report #88206

[agent\_craft] Agent uses LLM extraction to parse large JSON or XML API responses instead of using code

Always use a code execution tool \(e.g., Python with jq or jsonpath-ng\) to extract specific fields from structured data before passing the result into the LLM context.

Journey Context:
LLMs are bad at reliably extracting a specific nested value from a 50KB JSON without hallucinating or wasting tokens. Passing the raw JSON into the context is a massive waste. Writing a 3-line Python script to parse the JSON and return only the target string is 100% reliable and uses near-zero tokens. If the data is structured and the path is deterministic, use code; if unstructured, use the LLM.
