How many concurrent sessions can I run?

By default, the skill supports up to 5 concurrent sessions. This limit can be adjusted via the CLAUDE_CODE_X_MAX_SESSIONS environment variable if your system resources allow.

What happens if a background task fails?

If a session fails or times out, you can retrieve the full output logs to diagnose the issue, resolve any dependencies, and re-execute the task with refined instructions.

What is Claude Code X?

Claude Code X is an autonomous subagent skill that runs Claude Code tasks in the background, allowing developers to execute multiple coding jobs in parallel while continuing other work.

When should I avoid using Claude Code X?

Avoid using this skill for exploratory tasks, unclear requirements, or tasks that require frequent user decisions, as it is optimized for well-defined, independent execution.

Can I monitor tasks while they are running in the background?

Yes, you can check the status, progress, and real-time logs of any background session using the built-in status and result commands.

生産性とワークフロー

Enables autonomous background execution of Claude Code tasks with support for up to five parallel sessions.

概要

Claude Code X acts as a powerful task orchestration layer that offloads well-defined coding tasks to background subagents. It allows developers to maintain their creative flow by executing up to five independent sessions concurrently, handling repetitive or time-consuming implementation tasks while the user focuses on higher-level architecture or other work. This skill is ideal for batch refactoring, boilerplate generation, and multi-module updates where tasks are independent and well-defined.
