implement-sub-agents

To create and validate Claude sub-agent definitions, this Skill generates agent files with explicit roles and configurations, then verifies frontmatter, tool permissions, and delegation boundaries for safe deployment.

Frontmatter requirements for building Claude sub-agents include metadata fields that define explicit roles, tool permissions, and delegation boundaries, which are validated to ensure adherence to agent design best practices.

You validate tool permissions and delegation boundaries for AI agents by running validation scripts against the agent definition file to verify security configurations and ensure adherence to safe delegation limits.

Yes, you can use this Skill to update existing sub-agent definitions by modifying the agent file to adjust explicit roles, boundaries, and configurations, followed by validating the updated frontmatter and tool access settings.

The best way to ensure AI agent safety before deployment is to generate definition files and verify their tool permissions, frontmatter adherence, and delegation boundaries using validation scripts.

Claude sub-agent validation scripts fail on frontmatter when the agent definition file does not adhere to required frontmatter rules, secure tool permissions, or well-defined delegation boundaries specified in the reference documentation.
