# Create Subagent This skill provides comprehensive guidance for creating and configuring subagents in Claude Code. ## Understanding Subagents Subagents are specialized AI assistants that Claude Code can delegate tasks to. Each subagent: - Operates in its own context window (preserving main conversation context) - Has a specific purpose and expertise area - Can be configured with specific tools and permissions - Includes a custom system prompt guiding its behavior ### When to Create Subagents **Create a subagent when:** - Tasks require specialized expertise that benefits from focused instructions - Context preservation is important (subagents don't pollute main context) - The same specialized workflow is needed repeatedly - Different tool permissions are needed for different tasks - Parallel execution of independent tasks is desired **Choose skills instead when:** - The capability extends Claude's knowledge without needing separate context - No specialized agent persona is needed - Tool restrictions are sufficient without full agent isolation **Choose slash commands when:** - Users need explicit control over when to invoke functionality - The workflow should be user-initiated, not

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill create-subagent-cygnusfear-claude-stuff --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
