What it does
Animated Content is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing slow page loads, heavy assets, or rendering delays related to Convert animated GIFs to video. Verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.
Its SKILL.md is about 410 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 Social media graphics and Web performance. 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
- Auditing slow page loads
- Rendering delays related to Convert animated GIFs to video
Example prompts
- “/animated-content”
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
Animated Content loads about 413 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 161 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.

Convert animated GIFs to video
Large animated GIFs can significantly increase page weight and consume excessive CPU/memory, leading to slower page loads and poor scrolling performance.
Quick Reference
- Use
<video>instead of large GIFs for animations - GIFs are significantly larger than MP4/WebM
- Videos allow for better control and performance
Check
Check for large animated GIFs that could be replaced with more efficient video formats like MP4 or WebM.
Fix
Convert animated GIFs to MP4 or WebM and use the <video> tag with autoplay, loop, muted, and playsinline attributes.
Explain
Explain why video formats are more efficient than GIFs for animated content and how they improve performance.
Code Review
Review the routes, assets, and loading behavior that affect Convert animated GIFs to video. Flag exact files, requests, or rendering steps that add unnecessary network, CPU, or layout cost, and describe the measurement method used to confirm the issue.
