What it does
Video Captions is an agent skill from thedaviddias/Front-End-Checklist. Use when applies to all <video elements and third-party video embeds (YouTube, Vimeo) where the page owner controls the content. Prerecorded videos require .vtt caption files via <track. For videos embedded via <iframe, check that the video platform captions are enabled. Audio-only content requires transcripts instead (SC 1.2.1). Video-only content (no audio) requires a text alternative or audio description instead (SC 1.2.3).
Its SKILL.md is about 1k 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 Media & Creative, covering Transcription. It works with YouTube. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.

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
Video Captions loads about 1k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 470 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 captions for video content
Approximately 15% of adults have some degree of hearing loss. Captions are essential for deaf and hard-of-hearing users who cannot access audio content. They also benefit users in sound-sensitive environments (libraries, open offices), users watching without headphones in public, non-native speakers, and users with auditory processing disorders. WCAG SC 1.2.2 is a Level AA requirement — its absence is a legal compliance failure under the ADA, EN 301 549, and similar regulations worldwide.
Quick Reference
- Prerecorded video with audio: synchronized captions required — WCAG 2.1 SC 1.2.2 (Level AA)
- Live video with audio: real-time captions required — WCAG 2.1 SC 1.2.4 (Level AA)
- Use
<track kind='captions'>with a.vtt(WebVTT) file for HTML5<video>elements - Captions must include all spoken dialogue, speaker identification, and relevant non-speech audio (music, sound effects)
- Subtitles and captions are different: captions include non-speech audio; subtitles translate dialogue only
Check
Find all <video> elements and video embeds (<iframe> from YouTube, Vimeo, etc.). For each <video> with audio: check for a <track> child element with kind='captions' and a valid src pointing to a .vtt file. Verify the default attribute is present on at least one track so captions are on by default (or document the UX reason they are off by default). For YouTube/Vimeo embeds: check that the platform's caption toggle is accessible. Also check that the .vtt file exists and is valid (not empty, not just music notes).
Fix
For <video> elements without captions: (1) Create a WebVTT (.vtt) file containing synchronized caption text — include all spoken words, speaker IDs for multi-speaker content, and descriptions of relevant sounds (e.g., '[applause]', '[upbeat music]'). (2) Add <track kind='captions' srclang='en' label='English' src='captions-en.vtt' default> inside the <video> element. (3) For auto-generated captions (YouTube, AI tools): review and correct errors — auto-captions average 80% accuracy and often fail on proper nouns, technical terms, and accented speech. (4) For live streams: implement real-time captioning via a third-party captioning service or CART (Communication Access Realtime Translation).

Explain
WCAG 2.1 SC 1.2.2 (Captions — Prerecorded, Level AA) requires synchronized text alternatives for all audio in prerecorded video content. Captions differ from subtitles: captions are intended for deaf/hard-of-hearing viewers and must include non-speech information (sound effects, music), while subtitles translate dialogue for viewers who can hear but do not understand the language. The HTML <track> element with kind='captions' delivers WebVTT files that browsers render as synchronized on-screen text. The kind='subtitles' value is for translation only and does not satisfy SC 1.2.2 because browsers may omit non-speech annotations.
Code Review
Review the rendered markup and interactive states that affect Provide captions for video content. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
