To create a Claude Code agent, define its identifier, description, model, color, and tools in YAML frontmatter, then add examples and a system prompt in the Markdown body to establish identity and behavior.

Designing Claude Code agents requires the Claude Code framework and associated agent-creation plugins installed in your environment to support proper agent execution and context management during task automation.

A system prompt defines agent behavior by providing specific instructions in the Markdown body, ensuring the autonomous subprocess meets your project-specific needs and handles multi-step tasks independently.

You validate agent configurations and test triggers by checking the defined YAML frontmatter and Markdown instructions against expected behaviors to ensure proper functionality before deploying the agent for automated tasks.

The best way to structure YAML frontmatter for an agent is to specify the identifier, description, model, color, and available tools, which collectively define the agent's core identity and execution environment.

Yes, you can build autonomous subprocesses with Claude Code that handle multi-step tasks independently by defining clear triggers and system prompts within the agent configuration.
