SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and scripts (resource) components.

What problem does it solve?

This Skill documents how to design and configure autonomous agents for Claude Code plugins, enabling Claude to operate agents that can perform complex, multi-step tasks with minimal human input. It covers trigger conditions, system prompts, model/color/tool configurations, and best practices for reliable autonomous behavior.

Core Features & Use Cases

Frontmatter-driven agent identity and invocation
Structured system prompts defining core responsibilities and analysis workflow
Triggering patterns through descriptive examples
Model/color/tool configuration for controlled autonomy
AI-assisted vs manual agent creation workflows
Production-ready examples (code-review, test-generation, documentation writers)

Quick Start

Create a new agent file at agents/agent-name.md with proper frontmatter, then supply the system prompt body. Use the provided JSON-generation flow to derive the frontmatter and system prompt, and validate with the project’s agent validation tooling.
