When your agent uses it

- Component styles
- Responsive behavior related to Avoid embedded and inline CSS
Example prompts
- “/embedded-or-inline-css”
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
Embedded Or Inline CSS loads about 435 tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 58 tokens; SKILL.md has 169 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.

Avoid embedded and inline CSS
Inline CSS cannot be cached separately, increases HTML payload, breaks separation of concerns, and is harder to maintain in large codebases.
Quick Reference
- Move inline styles to external CSS files or CSS-in-JS
- Exception: critical CSS should be inlined for performance
- Exception: dynamic values (CSS custom properties) can be inline
- Inline CSS breaks caching and increases HTML size
Check
Verify that inline CSS and embedded styles are avoided except for valid use cases like critical CSS, dynamic styles, or performance optimization.
Fix
Move inline and embedded CSS to external stylesheets, keeping only critical above-the-fold CSS inline for performance optimization.
Explain
Explain why external CSS is preferred for maintainability, caching, and separation of concerns, with exceptions for critical CSS and dynamic styles.
Code Review
Review stylesheets, component styles, and responsive states related to Avoid embedded and inline CSS. Flag exact selectors, declarations, or breakpoints that violate the rule in the rendered UI.
