Report #46606

[synthesis] Agent loops derail silently after receiving truncated grep/search output

Enforce a 'summary-first' tool pattern or hard token limit on search results, forcing the agent to process chunks before continuing, or switch to structured data return types instead of raw text.

Journey Context:
Single sources discuss context limits or tool output truncation separately. The synthesis reveals that truncation isn't just an information loss problem; it creates a 'sunk cost' loop. The agent sees partial results, assumes the answer is just beyond the truncation limit, and narrows its search infinitesimally rather than abandoning the strategy. The fix isn't just 'more context' but breaking the agent's assumption that the tool output is exhaustive.
