SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Designing consistent, well-documented Claude Code agents is complex. This skill provides a standardized blueprint for agent creation, including required frontmatter, system prompt structure, and best-practice examples to accelerate safe, repeatable development.

Core Features & Use Cases

  • Frontmatter-driven agent metadata: name, description, model, color, and tools.
  • Comprehensive system prompts: responsibilities, analysis process, output format, and edge-case handling.
  • Triggering examples: 2–4 scenarios to illustrate when to invoke the agent and when not to.
  • Validation guidance: clear checks for identifier, description, system prompt, and testing workflow.

Quick Start

Create a minimal agent configuration with a unique identifier, a clear triggering description including 2–4 examples, a model, a color, and a concise system prompt.
