Report #49767

[synthesis] Agent loops derail silently after large tool output without throwing an error

Truncate or summarize tool outputs aggressively before returning them to the agent context, and inject a 'state reminder' system prompt after long outputs to re-anchor the agent's attention on the original goal.

Journey Context:
Agents often fail not because the context window is full, but because the attention mechanism is diluted. A massive unstructured tool output \(like a log file\) shifts the latent space away from the original objective. The agent doesn't error; it just starts hallucinating unrelated next steps or fixates on irrelevant details in the output. Simply increasing context size makes this worse by providing more space for distraction. The tradeoff is losing granular detail vs. losing the plot entirely.
