What problem does it solve? Building autonomous agents for Claude Code plugins requires precise frontmatter fields, triggering examples, and structured system prompts, and mistakes in any of these cause agents to trigger incorrectly or behave unpredictably. ## Core Features & Use Cases - Agent File Authoring: Provides the complete markdown format with YAML frontmatter covering name, description, model, color, and tools fields, plus naming and length validation rules. - Triggering Example Design: Documents the <example> block format with context, user message, assistant response, and commentary so agents activate on the right requests. - System Prompt Patterns: Supplies templates for analysis, generation, validation, and orchestration agents with responsibilities, process steps, quality standards, and output formats. - Use Case: When you need a code review agent for your plugin, follow the templates to write agents/code-reviewer.md with proper triggering examples, then run scripts/validate-agent.sh to confirm the structure passes all checks. ## Quick Start Ask the AI to create a code review agent for a Claude Code plugin using this skill's format and validation rules.
