Report #51212

[synthesis] Agent misses edge-case errors from tools that previously worked perfectly

Preserve the exact HTTP status code and structured error JSON in the tool output payload to the LLM, avoiding middleware that converts errors to generic string summaries.

Journey Context:
To save context tokens, developers write middleware that summarizes tool outputs, e.g., converting a 403 JSON with specific permission errors into 'Error: Access Denied'. The LLM loses the context needed to self-correct \(e.g., trying a different scope\). The agent reports failure, but the monitoring just sees 'tool failed,' missing that the agent's recovery capability was silently destroyed by the summarization layer. Preserving structured errors costs tokens but enables the agent's native reasoning to handle edge cases.
