What it does
Alt Text is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing image assets, markup, and CDN or build transforms related to Provide meaningful alt text for images. Check encoded size, rendered size, loading strategy, and above-the-fold impact together.
Its SKILL.md is about 780 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 Accessibility. 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 Provide meaningful alt text for images
Example prompts
- “/alt-text”
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
Alt Text loads about 775 tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 391 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.

Provide meaningful alt text for images
Approximately 2.2 billion people worldwide have vision impairment. Screen readers read the alt attribute aloud—without meaningful alt text, users who are blind receive no information about image content. Missing alt text also fails WCAG 2.1 Success Criterion 1.1.1, which is a Level A (minimum) requirement. Search engines also rely on alt text to index image content.
Quick Reference
- Every
<img>must have analtattribute—omitting it entirely violates WCAG 2.1 SC 1.1.1 - Decorative images use
alt=""so screen readers ignore them - Alt text should describe the image's purpose, not just its appearance
- Linked images: alt describes the link destination, not the visual
Check
Scan all <img> elements in the codebase. Verify: 1) Every <img> has an alt attribute (missing alt is an error). 2) Decorative images use alt="". 3) Informative images have descriptive text that conveys the image's meaning—not just its file name. 4) Images that are links describe the destination. 5) Images of text reproduce the text in alt. Flag any <img> without alt, with alt matching the filename (e.g., alt="photo1.jpg"), or with generic values like alt="image" or alt="photo".
Fix
For each image missing or with poor alt text: 1) Informative images—describe what the image conveys, not just what it shows (e.g., alt="Bar chart showing 40% increase in sales Q3 2024" not alt="chart"). 2) Decorative images—add alt="" so screen readers skip them. 3) Linked images—describe the link destination (e.g., alt="Visit our Twitter profile"). 4) Images of text—copy the text verbatim into alt. 5) Complex images (charts, infographics)—provide a short alt plus a longer description via aria-describedby or a visible caption.

Explain
Explain WCAG 2.1 Success Criterion 1.1.1 Non-text Content: every image must have a text alternative. Screen readers announce the alt attribute aloud—without it, users who are blind or have low vision cannot understand the page. Bad alt text (like alt="image") is no better than no alt text. Decorative images must use alt="" explicitly so screen readers skip them entirely—omitting alt causes some screen readers to announce the filename.
Code Review
Review image assets, markup, and delivery configuration related to Provide meaningful alt text for images. Flag exact files or components where format choice, sizing, or loading behavior violates the rule, and describe how to confirm the fix in DevTools.
