HomeClaude Code Unveils Monitor Tool for Real-Time Background Process Monitoring
Anthropic's Claude Code today released a new Monitor tool, a background monitoring feature that lets Claude spawn background processes, monitor stdout output of external processes in real time, and stream results directly into the conversation interface.
Per the official announcement, the Monitor tool’s key strength is its real-time push mechanism. Claude creates a background process that doesn’t block the main thread; whenever the process produces output, the content is streamed into the conversation instantly. Claude can respond immediately, eliminating the need for users to repeatedly check or wait for the process to complete.
This feature fundamentally shifts away from the old polling inquiry model. Traditional approaches required continuous polling within the agent loop, consuming more tokens and risking delays from waiting. Now, output is pushed immediately, enabling Claude to intervene in real time — boosting efficiency and reducing token usage.
Practical application scenarios include:
See error messages in real time while running test scripts in the background, so Claude can assist with fixes immediately without waiting for the full script to finish before checking logs. Monitor logs for errors, use scripts to poll for PR updates, track build events, and more.Compared to repeated polling inside the agent loop, the Monitor tool is more reliable and resource-efficient, helping AI agents transition from simple chatbots to true background services.
Noah Zweben, Product Manager of Claude Code, said this feature marks an important step toward making agents "wake up on demand," fitting a range of development use cases including log monitoring and PR tracking. Early user feedback highlights a significant improvement in the interaction experience for long-running tasks.
