Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install mermaid-diagram-authoring-2

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 chooses the diagram type that fits your message (flow, timeline, roadmap and so on), writes the Mermaid code and checks it before delivery. You get a code block ready to drop into a PRD, spec or deck.
