web-asset-generation is a skill for Claude Code from itallstartedwithaidea/agent-skills. It costs 42 tokens per session (2,003 once invoked), scanned A, original, MIT.

A process for creating the image files and HTML configuration a modern website needs from one source image or brand specification. It includes browser icons, app icons, social-sharing images, and related metadata.

In plain words
What is it for?
Generating favicons, Apple touch icons, PWA icons, Open Graph and Twitter images, HTML meta and link tags, and a web manifest for a website or web app.
Why use it?
Websites need several image sizes and formats for browser tabs, phone home screens, progressive web apps, and social-media previews. Creating each variant and tag by hand makes omissions and incorrect previews more likely.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-asset-generation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Web Asset Generation

Part of Agent Skills™ by googleadsagent.ai™

Description

Web Asset Generation automates the creation of favicons, PWA icons, Open Graph images, social media meta tags, and Apple touch icons from a single source image or brand specification. The agent produces the complete set of assets required for a modern web application—across all platforms, sizes, and formats—with proper HTML meta tags and web manifest configuration.

A professional web presence requires dozens of image variants: 16x16 and 32x32 favicons, 180x180 Apple touch icons, 192x192 and 512x512 PWA icons in both regular and maskable formats, 1200x630 Open Graph images, 1200x600 Twitter cards, and platform-specific splash screens. Generating these manually is tedious and error-prone; forgetting a single variant means broken previews on a specific platform. This skill automates the entire pipeline.

Beyond icon generation, the skill produces the associated configuration: HTML <link> and <meta> tags for the document head, manifest.json for PWA support, and platform-specific meta tags for Twitter Cards, Facebook Open Graph, and LinkedIn. The output is copy-paste ready—a complete set of assets with the HTML to reference them.

Use When

  • Setting up favicon and icon assets for a new web project
  • Generating Open Graph images for social media sharing
  • Configuring PWA manifest with proper icon sizes
  • Creating social media meta tags (Twitter Cards, OG tags)
  • Rebuilding assets after a brand update or redesign
  • The user asks for "favicon", "OG image", "PWA icons", or "social meta tags"

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
