SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides a structured blueprint for creating autonomous, self-contained agents that can be used within Claude Code plugins. It ensures consistent frontmatter, robust system prompts, and clearly defined triggering behavior across projects, reducing ambiguity and onboarding time.

Core Features & Use Cases

  • Frontmatter-driven agent metadata generation and validation against CLAUDE.md conventions.
  • System prompt design templates that specify responsibilities, process steps, output formats, and edge-case handling.
  • Triggering example generation and validation to ensure reliable agent invocation in diverse scenarios.
  • Built-in toxicity checks and safety considerations aligned with policy.

Quick Start

Use a simple natural-language instruction to generate a complete agent configuration, including frontmatter and system prompt, ready for validation.

FAQPage Schema
How do I create autonomous agents for Claude Code plugins?

To create autonomous agents for Claude Code plugins, generate self-contained metadata units with required frontmatter fields like name, description, model, and color, alongside structured system prompts. This enforces consistent agent behavior and reduces onboarding ambiguity across projects.

What is a system prompt design template for plugin agent development?

A system prompt design template for plugin agent development specifies agent responsibilities, process steps, output formats, and edge-case handling. It ensures autonomous Claude Code agents execute tasks reliably by enforcing structured outputs and built-in toxicity checks.

How do I validate triggering examples for autonomous agents?

Validating triggering examples for autonomous agents involves generating test scenarios and checking them against defined invocation criteria within plugin directories. This ensures agents activate reliably in diverse contexts and conform to CLAUDE.md conventions.

What frontmatter fields are required for a Claude Code plugin agent?

Required frontmatter fields for a Claude Code plugin agent are name, description, model, and color. Validating these metadata units guarantees the autonomous agent configuration is recognized and functions correctly within the plugin directory structure.

Does Claude Code plugin agent development require external dependencies?

Claude Code plugin agent development does not require external dependencies. It operates as a self-contained workflow using natural language instructions to generate and validate frontmatter, system prompts, and triggering examples within your existing environment.

Why are my Claude Code plugin agents not triggering correctly?

Claude Code plugin agents fail to trigger correctly when frontmatter is incomplete or triggering examples lack diverse scenarios. Ensure your agent metadata includes all required fields and validated examples to guarantee reliable invocation across different contexts.
