What it does
Font Loading is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing slow page loads, heavy assets, or rendering delays related to Optimize web font loading. Verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.
Its SKILL.md is about 400 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 Typography 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 Optimize web font loading
Example prompts
- “/font-loading”
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
Font Loading loads about 400 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 150 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.

Optimize web font loading
Slow font loading can cause 'Flash of Invisible Text' (FOIT) or significant layout shifts, negatively impacting both user experience and Core Web Vitals.
Quick Reference
- Use
font-display: swapto prevent invisible text during load - Preload critical fonts to discover them earlier
- Use modern formats like WOFF2 for better compression
Check
Check font loading strategies and verify that font-display is used and critical fonts are preloaded.
Fix
Add font-display: swap to @font-face declarations and use <link rel='preload'> for the most important fonts.
Explain
Explain how font loading affects perceived performance and layout stability.
Code Review
Review the routes, assets, and loading behavior that affect Optimize web font loading. 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.
