Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Audit static HTML files for on-page SEO, content quality, easy-win performance signals, and crawlability. This skill should be used when the user asks to review, audit, or check the SEO of one or more static HTML files — e.g., "review the HTML for SEO issues", "audit this landing page", "check SEO on these pages before I publish". Static HTML only — does not cover Jekyll/Hugo/Astro/Next.js source, off-page factors, or live-rendered Core Web Vitals.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'html-seo-review' ] || [ -L ~/.agents/skills/'html-seo-review' ]; then echo 'A skill folder named html-seo-review already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/NickCrew/Claude-Cortex' "$d" && git -C "$d" checkout --quiet 'bb47af79ad3befe01ae01940fcf5f16e30a1b6df' -- 'skills/html-seo-review' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/html-seo-review' ~/.agents/skills/'html-seo-review' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'html-seo-review' ~/.claude/skills/'html-seo-review' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
