Report #25364

[synthesis] Agent reads massive log file, floods context window, and forgets original instructions

Tools must enforce strict output truncation limits \(e.g., head -n 100 or tail -n 50\), and agents should use paginated or grep-based search tools instead of broad cat or ls -R commands.

Journey Context:
A common failure mode is 'read the log to find the error'. The agent runs cat server.log, injecting 50,000 tokens into the context. The original task prompt gets evicted, and the agent starts acting erratically or loops. Truncation and targeted search preserve the context window for actual reasoning. The tradeoff is that the agent might miss the error if it doesn't know the line number, but preserving context is more important.
