Claude Code Monitor Tool: Stream stdout in Background Processes
Learn how Claude Code’s Monitor tool streams stdout from background processes for reliable, token-efficient log tracking without blocking execution.
New feature in Claude Code: the Monitor tool
Claude spins up a background process, and each line from stdout is streamed into the dialog without blocking the execution flow.
For example: “Use the monitor tool and kubectl logs -f | grep .. to track errors, and make a PR to fix any failures.”
This is both more reliable and more token-efficient than polling inside the agent loop.
