What problem does it solve? Apps deployed on *.grok.me need correct Open Graph share cards, favicons, and PWA icons so links unfurl properly on social platforms, but the meta tags are injector-owned and easy to misconfigure. ## Core Features & Use Cases - Custom share cards: Generates a 1200×630 public/og.jpg card from the app's own art, with baked-in title lockup and JPEG size discipline for reliable unfurling. - Game identity contract: Writes og:type as x:game in src/lib/og/site.json and produces the 50:11 public/x-banner.jpg feed card for games. - Favicon and PWA icons: Hand-authors a crisp public/favicon.svg and derives 192/512 raster icons only when the app ships a web manifest. - Use Case: After scaffolding a browser game, dispatch the brand-asset pass as a non-blocking subagent so the share card, favicon, and X banner land without blocking the main build. ## Quick Start Ask the agent to set up the share card and favicon for your app, and it will dispatch the brand-asset pass as a background subagent while it keeps building.
