Report #47418
[synthesis] Agent loops derail silently after processing large tool outputs without error codes
Truncate or summarize tool outputs before injecting them back into the context window, and enforce a strict token budget per tool response.
Journey Context:
Agents often fail because a tool returns a massive string. The LLM attempts to reason over the entire string, gets confused by noise, and starts hallucinating or looping. Developers often assume the agent needs the full output to be accurate, but the cognitive load of parsing thousands of lines in-context degrades the LLM's instruction-following capability, leading to silent derails. Summarization/truncation trades perfect information for maintained reasoning coherence, preventing the attention mechanism from being diluted by irrelevant tool artifacts.
