Report #41353

[synthesis] Agent exhausts context window and crashes because a directory listing tool returned thousands of files which it attempted to read sequentially

Configure file system tools to return paginated or truncated results by default, and explicitly instruct the agent to use grep/search tools to filter before reading, rather than reading files sequentially.

Journey Context:
A common failure mode is an agent running \`ls -R\`, seeing a large list, and deciding it needs to read every file to find the answer. This silently fills the context. The fix is to change the tool interface to prevent large returns and to instruct the agent on search strategies, mirroring how human developers navigate codebases rather than reading everything.
