To create an autonomous agent for a Claude Code plugin, draft a configuration file containing YAML frontmatter, a system prompt, and triggering examples, then save it under the agents directory as a markdown file.

A Claude Code agent configuration file is a self-contained markdown document that standardizes agent metadata, system prompts, and triggering examples to deploy autonomous agents within plugins.

Write a system prompt for a plugin agent by explicitly defining its responsibilities, processing steps, edge cases, output formats, and quality standards to ensure robust autonomous execution.

Required fields in agent frontmatter for Claude Code include name, description, model, and color, while optional fields like tools and version help standardize agent metadata across plugins.

An autonomous agent should include 2 to 4 triggering examples that demonstrate explicit and proactive usage across scenarios like code changes, documentation requests, and security reviews.

Validate a Claude Code agent before deployment by running recommended validation scripts and workflows to verify the agent file structure and trigger behavior within the plugin environment.
