# Mermaid Chart agent skills for Claude Code, Cursor and RevampKey

> Ready-made Mermaid Chart playbooks for AI agents: draft and publish Mermaid diagrams with AI, audit your saved Mermaid diagrams. Free SKILL.md files for Claude Code, Cursor and Codex, or one click in RevampKey.

## Skills

- [Use Mermaid Chart with AI](https://revampkey.com/marketplace/mermaid-chart/skills/essentials.md): Shows Mermaid diagrams in the conversation, and saves, lists or repairs them in your Mermaid.ai account when you sign in. It asks before changing anything in your account.
- [Draft and publish Mermaid diagrams with AI](https://revampkey.com/marketplace/mermaid-chart/skills/diagram-draft-and-publish.md): Turns a described process, sequence or structure into valid Mermaid code, renders it for review, and saves it to your Mermaid Chart account only after you approve it.
- [Audit your saved Mermaid diagrams](https://revampkey.com/marketplace/mermaid-chart/skills/diagram-library-audit.md): Reviews your saved Mermaid Chart diagrams for broken syntax, misleading titles and duplicates, then proposes a cleanup plan. It changes nothing until you approve each action.

### What is a Mermaid Chart agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each Mermaid Chart skill describes one job, which Mermaid Chart tools to use in which order, what to check first and when to stop and ask you.

### Do the Mermaid Chart skills change anything on their own?

The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in Mermaid Chart.

### Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect Mermaid Chart; elsewhere you copy the folders into your project or skills directory.

### Do I need the Mermaid Chart MCP server too?

Yes. The skills tell the agent how to do the work; the Mermaid Chart MCP server gives it the tools to do it. The Mermaid Chart MCP setup guide covers every client.
