Where should I save my custom Claude Code agents?

Agents can be stored in three locations: .claude/agents/ for project-specific use, ~/.claude/agents/ for personal cross-project use, or as temporary session-based agents via the CLI.

Can I audit existing subagent configurations?

Yes, this skill includes functionality to review your existing subagent files for syntax correctness, security risks, and alignment with prompting best practices.

What is a Claude Code subagent?

A subagent is a specialized persona or capability within Claude Code, configured via a markdown file with YAML frontmatter, designed to perform specific tasks with defined tools and constraints.

How do I restrict a subagent's access to my files?

You can define an allowlist in the 'tools' field or a denylist in the 'disallowedTools' field within the agent's YAML frontmatter to precisely control its capabilities.
