## Install

**For the person:** Open https://pr-316-stg.superartifacts.app/marketplace/cohort-heatmap, sign in, and press **Install** — one click, free. Then press **Build with this** to copy a prompt for your agent.

**For an agent with Super Artifacts MCP tools:**

1. `super_template_action` `{ "slug": "cohort-heatmap", "action": "install" }`
2. `super_templates` `{ "slug": "cohort-heatmap" }` — read it; its guidance arrives there, framed. Do not build until the person agrees.
3. `super_publish` `{ "template": { "slug": "cohort-heatmap" }, "values": { … } }`

**For an agent without them:** Tell the person to open the link above. To connect yourself, add the MCP server https://api-stg.superart.page/mcp (OAuth; the person approves once). Per-agent steps: https://pr-316-stg.superartifacts.app/docs/mcp.md
