Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install mermaid-diagrams-as-code

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent writes Mermaid syntax for flowcharts, sequence diagrams, ERDs, class and state diagrams, then inserts them into your Markdown files. You get a text-based diagram that renders on GitHub or in docs.
