Claude Agent Developer Kit

About

This skill provides a comprehensive framework for designing, configuring, and validating custom agents within the Claude Code ecosystem. It guides developers through the process of creating YAML frontmatter, defining precise triggering conditions with concrete example blocks, and architecting robust system prompts. By establishing best practices for tool selection, model inheritance, and visual identification, it ensures that developers can build highly effective autonomous subprocesses capable of handling complex, multi-step tasks independently.

Key Features

• System prompt templates for designing expert personas and workflows
• Standardized YAML frontmatter for agent metadata and configuration
• Validation rules for identifiers, description lengths, and prompt structures
• Tool restriction guidelines to implement the principle of least privilege
• Triggering logic using description fields and multi-context usage examples
• 81 GitHub stars

Use Cases

• Defining autonomous triggering conditions for background development tasks
• Standardizing plugin development workflows for consistent team collaboration
• Building specialized sub-agents like code reviewers or test generators
