At a glance
A skill your agent uses when reviewing image assets, markup, and CDN or build transforms related to Optimize SVG files.

What it does
SVG Optimization is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing image assets, markup, and CDN or build transforms related to Optimize SVG files. Check encoded size, rendered size, loading strategy, and above-the-fold impact together.
Its SKILL.md is about 390 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`).
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 Optimize SVG files
Example prompts
- “/svg-optimization”
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
SVG Optimization loads about 385 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 145 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 SVG files
SVGs exported from design tools contain unnecessary metadata, comments, and redundant code—optimization removes this bloat, often cutting file size in half.
Quick Reference
- SVGO can reduce SVG file size by 50-80%
- Removes editor metadata, comments, and redundant attributes
- Preserve viewBox and accessibility attributes
- Integrate into build process for automatic optimization
Check
Check if SVG files are optimized by removing unnecessary metadata and formatting.
Fix
Optimize SVG files using SVGO or similar tools to reduce file size.
Explain
Explain how SVG optimization can reduce file sizes by 50-80% without quality loss.
Code Review
Review image assets, markup, and delivery configuration related to Optimize SVG files. Flag exact files or components where format choice, sizing, or loading behavior violates the rule, and describe how to confirm the fix in DevTools.
