## What agent-skills does, in the publisher's words

A curated collection of production-grade, modular AI Agent Skills designed to enhance AI coding assistants (such as Google Antigravity, Claude Code, and other agentic IDE environments) with specialized domain knowledge, best practices, checklists, and automated workflows.

Every skill in this repository follows a standardized, progressive-disclosure package layout:

Agent skills are designed to minimize context token overhead:

- Only the skill's name and description from the YAML frontmatter in SKILL.md are indexed initially.
- When an agent recognizes a relevant user request (e.g., "Create a C4 container diagram for my microservices"), it loads SKILL.md on-demand and traverses linked documents in references/ as needed.
- The c4-diagram skill generates clean Mermaid C4 or PlantUML C4 syntax and invokes the Draw.io MCP Server (drawio) to render editable.drawio and.svg visual diagram files in the project.
