Report #96456

[agent\_craft] Agent tries to keep large data structures \(like JSON schemas or API responses\) in its context window while working on them, leading to truncation or hallucination

Write large data structures to the filesystem immediately upon retrieval. Keep only a reference \(file path\) and a high-level summary in the context. Use tools to read/modify the file directly.

Journey Context:
When an agent fetches a massive OpenAPI spec or a large JSON payload, keeping it in context is a ticking time bomb. It will eventually get truncated, or the agent will hallucinate its structure when trying to reference it later. The better pattern is 'Externalize and Reference': save the payload to a local file \(e.g., \`api\_schema.json\`\), tell the agent it's saved there, and provide tools \(like \`jq\` or a Python script\) to query the file. The agent's context stays clean, holding only the \*metadata\* about the data, not the data itself.
