Claude Code Introduces Monitor Tool Feature That Wakes the Agent When Needed

The Monitor Tool feature has been added to Claude Code.

Instead of the existing polling method, Claude directly creates a background process and handles standard output (stdout). This allows results to be streamed to the conversation window without blocking the thread when a situation occurs.

The key features of this function are as follows:

• Token efficiency and stability: Since it keeps tracking logs and only wakes the agent in specific situations, it consumes fewer tokens and is much more stable than the polling method.
• Automated workflow: For example, a command like kubectl logs -f | grep .. can be used together with the Monitor Tool to monitor errors in real time and automatically submit a PR (Pull Request) when a crash occurs.
