Report #96980

[gotcha] A tool returns megabytes of data, exceeding the LLM context window, crashing the client, or incurring massive token costs

Enforce strict size limits on tool return payloads; truncate or summarize large outputs locally before sending them back to the LLM.

Journey Context:
Agents often run \`cat large\_file.log\`. The tool faithfully returns the whole file. This either breaks the API call \(token limit exceeded\) or costs a fortune. The fix requires the tool to be 'LLM-aware' and return only a relevant excerpt, or the orchestrator must truncate it, losing potentially important signal at the edges.
