What it does
CSS Order is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing stylesheets, component styles, and responsive behavior related to Order CSS files correctly. Check the rendered layout across breakpoints and interaction states before proposing a fix.
Its SKILL.md is about 400 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`).
It sits in Frontend & Design, covering CSS and styling and Responsive design. It works with JavaScript. 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 stylesheets
- Component styles
- Responsive behavior related to Order CSS files correctly
Example prompts
- “/css-order”
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
CSS Order loads about 404 tokens when it runs, and up to ~5.2k if it reads all its reference files. Until then it costs about 53 tokens; SKILL.md has 157 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.

Order CSS files correctly
Incorrect CSS/JS order causes render-blocking delays and FOUC—users see unstyled content while waiting for styles to load.
Quick Reference
- Load all CSS files before JavaScript in the document head
- Use async/defer for non-critical JavaScript
- Inline critical CSS for faster first paint
- Prevents FOUC (Flash of Unstyled Content)
Check
Verify that all CSS files are loaded before JavaScript files in the document head to prevent render-blocking and ensure proper styling precedence.
Fix
Reorganize head section to load all CSS files before JavaScript files, except for asynchronous scripts that don't block rendering.
Explain
Explain why CSS should load before JavaScript to prevent FOUC (Flash of Unstyled Content) and ensure optimal rendering performance.
Code Review
Review stylesheets, component styles, and responsive states related to Order CSS files correctly. Flag exact selectors, declarations, or breakpoints that violate the rule in the rendered UI.
