SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Agent Development skill helps teams design and implement autonomous agents for Claude Code plugins, including crafting frontmatter, system prompts, triggering conditions, and best practices; it centralizes guidance to accelerate agent creation and ensure consistency.

Core Features & Use Cases

  • Templates for agent frontmatter to standardize identifiers and metadata
  • Frontmatter fields guidance: name, description, model, color, tools
  • System prompt architectural guidance: structure, responsibilities, process, and output expectations
  • Triggering examples: explicit and proactive usage scenarios
  • Validation and quality checks aligned with CLAUDE.md
  • Workflow guidance for creating, validating, and testing agents

Quick Start

Create a new agent by defining its identifier, description, model, color, and optional tools, then write a system prompt and 2-3 triggering examples.

FAQPage Schema
How do I create an autonomous agent for Claude Code?

To create a Claude Code agent, define its frontmatter fields including name, description, model, color, and tools, then write a comprehensive system prompt detailing its responsibilities and process. You also need to provide 2-3 triggering examples for explicit and proactive usage scenarios.

What is agent frontmatter and what fields does it require?

Agent frontmatter standardizes identifiers and metadata for Claude Code plugins. The required fields are name, description, model, color, and optional tools, which configure the agent's behavior and appearance within the system.

How do I write a system prompt for a Claude Code plugin?

Writing a system prompt requires defining the agent's structure, responsibilities, process, and output expectations. The prompt must align with project standards using CLAUDE.md context to ensure the agent behaves consistently and securely.

How do I validate an autonomous agent configuration before deployment?

Validate an autonomous agent configuration by running validation scripts that check security and quality alignment with CLAUDE.md. This ensures the agent markdown file meets project standards and is ready for use within your workflow.

Do I need to provide triggering examples when building a Claude Code agent?

Yes, providing 2-3 triggering examples is recommended. These examples define explicit and proactive usage scenarios, helping the autonomous agent understand when to activate and execute its designated tasks effectively.

Are there limitations when defining tools in agent frontmatter?

Tools in agent frontmatter are optional, but they must align with the project standards defined in CLAUDE.md. Validation scripts enforce security and quality checks to prevent misconfigured tool permissions during autonomous execution.
