Register Asset

Register Asset

Add an artifact to design-assets.json and refresh the visual overview at assets.html.

Argument parsing

From $ARGUMENTS:

• Positional 0: html-path (required)
• --asset "<name>": display name (default: derive from filename, Title Cased)
• --group <X>: one of Type, Colors, Spacing, Components, Brand (default: Components)
• --subtitle "<text>": short description
• --status <X>: needs-review | approved | changes-requested (default: needs-review)
• --auto: silent mode called by /done — skip thumbnail capture (reuses .claude/last-preview.png), don't print confirmation prompts, one-line report only

Steps

1. Capture thumbnail:

   • If --auto and .claude/last-preview.png exists: Bash(cp .claude/last-preview.png assets/thumbs/<slug>-<ts>.png) — reuse
   • Otherwise: /preview <html-path> → wait 500ms → mcp__chrome-devtools__take_screenshot → save to assets/thumbs/<slug>-<ts>.png (Bash(mkdir -p assets/thumbs) first)

2. Read existing design-assets.json:

   • If missing → create with {"items": []}

3. Upsert entry:

   • Key on (asset, path) pair
   • If exists → update fields + thumbnail + bump updated_at
   • If new → append

   Schema:

   {
     "items": [
       {
         "asset": "Primary button",
         "path": "artifacts/button.html",
         "group": "Components",
         "status": "approved",
         "subtitle": "Filled variant with hover state",
         "thumbnail": "assets/thumbs/button-20260420T120000Z.png",
         "registered_at": "2026-04-20T12:00:00Z",
         "updated_at": "2026-04-20T12:00:00Z"
       }
     ]
   }
   

4. Write design-assets.json with formatted JSON (2-space indent).

5. Regenerate assets.html:

   • Bash(node scripts/make-assets-index.mjs) — see script below
   • If user didn't run /doctor and node is missing, fall back to inline generation via Write tool with HTML template

6. Report: "Registered <asset> in <group>. View at assets.html."

assets.html layout

Sections by group. Each card shows:

• Thumbnail (clickable → opens source HTML in new tab)
• Asset name (bold)
• Subtitle (muted)
• Status badge (color-coded: green=approved, amber=needs-review, red=changes-requested)
• Updated date
• Mini-menu: approve, request-changes, unregister

The HTML is static — no server. Status changes happen via Claude (user says "approve the button asset" → Claude re-runs /register-asset ... --status approved).
