Generate AI images using Gemini or GPT APIs directly. Covers model selection (Gemini for scenes, GPT for transparent icons), the 5-part prompting framework, API calling patterns, multi-turn editing, and quality assurance. Produces photorealistic scenes, icons, illustrations, OG images, and product shots. Use when building websites that need images, creating marketing assets, or generating visual content. Triggers: 'generate image', 'ai image', 'create hero image', 'make an icon', 'generate illustration', 'create og image', 'ai art', 'image generation'.

Generate complete, accessible colour palettes from a single brand hex. Produces 11-shade scale (50-950), semantic tokens, dark mode variants, and Tailwind v4 CSS output. Includes WCAG contrast checking. Use when setting up design systems, creating Tailwind themes, building brand colours from a hex value, or checking colour accessibility.

Generate custom favicons from logos, text, or brand colours. Produces all required formats: favicon.svg, favicon.ico, apple-touch-icon.png, icon-192/512.png, and web manifest. Use when initialising websites, replacing CMS default favicons, converting logos to favicons, creating branded icons from initials, or troubleshooting favicon not displaying, iOS black square, or missing manifest.

Generate cohesive, project-specific SVG icon sets for websites and applications. Use this skill whenever the user needs custom icons, an icon set for a website or app, icons for a client project, or mentions needing SVG icons that look consistent together. Also trigger when the user describes a project and icons would naturally be part of the deliverable — e.g. "I'm building a site for a plumber" implies they'll need service icons. Trigger on: "icons for", "icon set", "custom icons", "SVG icons", "make me icons", "I need icons", "website icons", "project icons", or any request for consistent visual assets for a web project. This skill produces individual SVG files with a consistent style engine, not generic icon library lookups.

Process images for web development — resize, crop, trim whitespace, convert formats (PNG/WebP/JPG), optimise file size, generate thumbnails, create OG card images. Uses Pillow (Python) — no ImageMagick needed. Trigger with 'resize image', 'convert to webp', 'trim logo', 'optimise images', 'make thumbnail', 'create OG image', 'crop whitespace', 'process image', or 'image too large'.
