Report #15631
[agent\_craft] Shell command outputs \(logs, directory listings\) consume entire context window
Always pipe large outputs to head, tail, wc -l, or write to a file and use grep/awk before loading into context. Set a hard token limit on tool output truncation.
Journey Context:
A common mistake is letting an agent run cat large\_log.txt or find / and dumping the result directly into the context. This instantly causes context overflow and pushes out the system prompt or plan. The agent should treat the shell as a pre-processor. Instead of reading everything and filtering in-context, filter out-of-context via code execution. The tradeoff is an extra tool call, but it saves thousands of tokens and prevents context rot.
