What it does
When the user wants to implement, optimize, or audit favicon and app icons. Also use when the user mentions "favicon," "app icon," "browser icon," "touch icon," "PWA icon," "favicon sizes," "apple-touch-icon," "favicon.ico," "site icon," or "tab icon." For visual system, use brand-visual-generator.
Components: Favicon
Guides favicon and app icon implementation for brand consistency across browser tabs, bookmarks, mobile home screens, and Google Search results. Favicons help users identify sites; missing or incorrect icons hurt trust.
When invoking: On first use, if helpful, open with 1-2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Initial Assessment
Project context: Read root contextus.md when present and load only the modules relevant to this task. Without Contextus, use available project material or user-provided facts and ask for missing information; do not create a parallel context system.
Identify:
- Tech stack: Next.js, WordPress, static HTML, etc.
- PWA: Is the site a PWA or planning to be?
- Existing assets: Logo, icon files

Optional: 48x48, 96x96, 120x120, 152x152, 167x167, 256x256 for broader coverage.
Formats
