How many tasks can I run at once with Claude Code X?

The skill supports up to 5 concurrent sessions by default, allowing you to parallelize independent tasks across your codebase.

Can I check the progress of a background session?

Yes, the skill provides commands to list all active sessions, check the status of a specific session ID, and retrieve real-time logs.

Is the execution timeout configurable?

Yes, while the default timeout is 10 minutes, you can specify custom timeout durations for more complex tasks via the execution command.

What kind of tasks are best suited for this subagent?

It is ideal for well-defined, independent tasks that don't require human intervention, such as batch refactoring, adding documentation, or implementing standard logging patterns.

What happens if a background task encounters an error?

The session will log the error and terminate. You can use the 'result' command to view the full output log, diagnose the issue, and re-run the task with clarified instructions.

生産性とワークフロー

Executes well-defined coding tasks autonomously in the background with support for up to five parallel sessions.

概要

Claude Code X is a specialized subagent designed to maximize developer throughput by offloading well-defined, independent tasks to background execution. By enabling parallel processing of up to five concurrent sessions, it allows developers to focus on high-level architecture while the subagent handles repetitive implementations like logging, boilerplate, or refactoring across multiple modules. The skill includes a robust management system for tracking session lifecycles, monitoring progress in real-time, and retrieving detailed execution logs.

主な機能

Parallel Execution: Run up to 5 concurrent Claude Code sessions simultaneously
Configurable Constraints: Custom timeout controls and tool permission settings per task
7 GitHub stars
Session Management: Persistent JSON-based tracking of session IDs, PIDs, and statuses
Comprehensive Logging: Full output capture for auditing and troubleshooting results
Background Operation: Non-blocking task execution allows for uninterrupted manual work

ユースケース

Generating boilerplate code for several new services or components simultaneously
Applying repetitive changes (like logging or error handling) across multiple repository modules in parallel
Running independent, time-consuming file edits in the background while continuing interactive development
