At a glance
A skill your agent uses when reviewing image assets, markup, and CDN or build transforms related to Use image sprites where appropriate.
- Reviewing image assets
- SKILL.md covers Quick Reference, Check, Fix and Explain, plus 1 more section

What it does
Sprite Generation is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing image assets, markup, and CDN or build transforms related to Use image sprites where appropriate. Check encoded size, rendered size, loading strategy, and above-the-fold impact together.
Its SKILL.md is about 410 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).
The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.
When your agent uses it
- Reviewing image assets
- Build transforms related to Use image sprites where appropriate
Example prompts
- “/sprite-generation”
What it can do on your machine
Read from SKILL.md and the folder at commit e8d14d0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
frontendchecklist.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Sprite Generation loads about 411 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 167 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Use image sprites where appropriate
Each image is an HTTP request—combining many small images into one sprite reduces requests, though modern HTTP/2 and SVG icons have reduced this need.
Quick Reference
- Sprites combine multiple images into one to reduce HTTP requests
- Modern alternative: SVG icon systems (more flexible)
- HTTP/2 makes sprites less critical but still useful for small icons
- Consider inline SVG or icon fonts for most icon use cases
Check
Check if small images and icons are combined into sprites to reduce HTTP requests.
Fix
Create CSS sprites for icons and small images, or migrate to SVG icons.
Explain
Explain how sprites reduce HTTP requests but consider modern alternatives like SVG icons.
Code Review
Review image assets, markup, and delivery configuration related to Use image sprites where appropriate. Flag exact files or components where format choice, sizing, or loading behavior violates the rule, and describe how to confirm the fix in DevTools.
