At a glance

A skill your agent uses when reviewing sticky navigation, consent banners, chat widgets, skip links, or any fixed-position UI.

  • Reviewing sticky navigation
  • SKILL.md covers Quick Reference, Check, Fix and Explain, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Consent banners

What it does

Focus Not Obscured is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing sticky navigation, consent banners, chat widgets, skip links, or any fixed-position UI. Validate the actual tab order and viewport behavior at realistic zoom levels.

Its SKILL.md is about 490 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. 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 sticky navigation
  • Consent banners
  • Any fixed-position UI

Example prompts

  • “/focus-not-obscured”

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

Focus Not Obscured loads about 490 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 211 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~490
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

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.

Keep focused elements unobscured

A visible focus ring is not enough if the focused element sits behind a sticky header or footer. Keyboard users need to see the actual focused control and the focus indicator at the same time in order to continue the task.

Quick Reference

  • Sticky UI must not cover the focused control while keyboard users tab through the page
  • Use scroll-padding or equivalent spacing when fixed headers or footers are present
  • Test with cookie banners, chat widgets, and consent bars open
  • Re-test at zoomed and mobile layouts where overlap problems usually appear

Check

Audit keyboard focus with all sticky UI active. Check headers, footers, cookie banners, promo bars, and chat launchers for cases where the focused element scrolls underneath them.

Fix

Add layout spacing such as scroll-padding, reduce overlay height, or change focus/scroll behavior so the focused element remains visible when tabbing.

Explain

Explain WCAG Focus Not Obscured, why fixed-position UI commonly breaks it, and how scroll-padding and overlay layout choices prevent the issue.

Code Review

Review sticky layout, focus styles, overlays, and keyboard navigation related to Keep focused elements unobscured. Flag exact selectors, breakpoints, or UI states where focused controls can be covered.
