What it does
Element Hiding is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing a website for layout and functionality issues caused by adblocker filter rules targeting common ad-related class names and IDs.
Its SKILL.md is about 600 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 Legal & Compliance. 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 a website for layout and functionality issues caused by adblocker filter rules targeting common ad-related class names and IDs
Example prompts
- “/element-hiding”
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
Element Hiding loads about 596 tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 40 tokens; SKILL.md has 259 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.

Adblock Element Hiding
If your cookie consent banner has class .cookie-banner or ID #consent-popup, adblockers may hide it — users never see the consent notice, which can cause GDPR compliance issues and broken UX for ~30-40% of desktop users.
Quick Reference
- Adblockers use EasyList filter rules to hide elements with class names, IDs, or patterns associated with ads
- Common blocked names:
.ad,.ads,.advertisement,.banner,#ad,#ads,#banner,.sponsor - Affected elements: legitimate banners, notification bars, promotional sections, and cookie consent notices
- Test your site with uBlock Origin enabled — check for missing content, broken layouts, or hidden consent banners
- Rename affected elements using semantic, content-specific class names to avoid false-positive blocking
Check
Review the HTML source for element IDs and class names that match common adblocker patterns: .ad, .ads, .advertisement, .banner, .sponsor, #ad, #banner, .cookie-notice, .consent. Test the page with uBlock Origin enabled in a browser to identify elements that are hidden.
Fix
Rename affected elements using specific, content-focused class names that do not match adblocker patterns. For cookie consent banners specifically, use class names like .privacy-controls or .cookie-preferences instead of .cookie-banner or .gdpr-notice.
Explain
Explain how adblocker filter lists work, which HTML class names and IDs are commonly blocked, and how to rename elements to avoid false-positive blocking while maintaining their function.
Code Review
Review server config, headers, forms, and integration points related to Adblock Element Hiding. Flag exact responses, cookies, or browser behaviors that violate the rule, and verify them against the effective production-like response.
