SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Long-running processes like servers, watchers, and long builds can block AI agent execution, causing delays and stalled workflows. This Skill provides a pattern to run these tasks asynchronously so the agent remains responsive.

Core Features & Use Cases

  • Use the WaitMsBeforeAsync parameter to detach long-running commands after startup.
  • Verify background processes with a completion/status check and safe termination when needed.
  • Handles common blockers, errors, and recovery steps in development automation.

Quick Start

Use run_command with WaitMsBeforeAsync to start a long-running server in the background and immediately regain control.

Frequently Asked Questions about Non-Blocking Execution

FAQPage Schema
How do I stop long-running server commands from blocking my AI agent?

Long-running builds block agent execution by preventing further commands from running. Running these tasks asynchronously detaches the process after startup, allowing the agent to verify status and regain control immediately without waiting for the build to finish.

How do I start a background watcher without stalling an automated workflow?

Start a background watcher without stalling an automated workflow by running the command with a WaitMsBeforeAsync parameter. This detaches the watcher process after a specified startup window, returning control to the agent immediately for other tasks.

How does an agent verify a detached process started successfully?

An agent verifies a detached process started successfully by running a verification loop after the command detaches. This checks the background process status and safely terminates the process if startup fails, ensuring reliable recovery from errors.

Can I safely terminate a background process started by an agent?

You can safely terminate a background process started by an agent during development. This approach implements safe termination to recover from failures, allowing the agent to stop detached servers or watchers cleanly when a task completes or encounters an error.

What is the WaitMsBeforeAsync parameter used for in non-blocking execution?

The WaitMsBeforeAsync parameter is used to delay the detachment of a long-running command. It allows the agent to monitor the initial startup of a server or watcher before moving the process to the background to prevent blocking.
