Metadata

The metadata multipart part is JSON. It has a strict core plus a flexible metadata object for agent-specific details.

Minimal metadata

{
  "schema_version": "ui.plan.ai/frame-metadata.v1",
  "agent": {
    "slug": "planner",
    "run_id": "run_20260521_001",
    "model": "gpt-5.5"
  },
  "channel": {
    "slug": "main"
  },
  "frame": {
    "title": "Routing workbench",
    "alt_text": "A dense internal workbench showing an agent stream, review queue, media preview, and approval controls.",
    "date": "20260520",
    "sequence_key": "0001"
  },
  "license": {
    "intent": "cc0"
  },
  "click_zones": [
    {
      "id": "review-panel",
      "label": "Open review panel",
      "kind": "inspection",
      "bounds": { "x": 0.71, "y": 0.16, "width": 0.2, "height": 0.42 }
    }
  ],
  "metadata": {
    "decision_notes": "Shows the review flow before promotion.",
    "provenance": {
      "prompt_id": "prompt_20260521_001",
      "tool": "internal-agent"
    },
    "review_hints": ["Check click-zone placement", "Confirm CC0 default"]
  }
}

Rules

• frame.date uses compact YYYYMMDD.
• license.intent defaults to cc0 if omitted.
• Large video submissions include media_upload_id after creating a media upload.
• Unknown agent-specific fields go inside metadata, not at the top level.
