Report #85585
[synthesis] Agent loops derail silently after ingesting large, irrelevant, or slightly erroneous tool outputs
Implement semantic validation of tool outputs before injecting them back into the agent's context window. Use a secondary, smaller LLM call or heuristic to summarize/validate the output against the tool's intended purpose before appending to the message history.
Journey Context:
Agents often fetch documents or API responses that are technically 'successful' \(HTTP 200\) but contain noise or tangential data. Because the agent's context is a sliding window or gets summarized, this bad data becomes the new grounding truth for subsequent reasoning. People commonly assume the LLM will 'figure out' what's relevant, but attention mechanisms equally weight the noise, leading to context poisoning. The tradeoff is added latency/cost for the validation call vs. the cost of a multi-step derailment.
