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

Frontend security: safe rendering and XSS, sanitising user HTML and markdown, a Content Security Policy, where tokens live, CSRF with cookies, public environment variables, third-party scripts, redirects, postMessage, iframes and clickjacking, and dependency hygiene. Read before rendering user content, handling auth on the client, or adding a script.

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/'frontend-security' ] || [ -L ~/.agents/skills/'frontend-security' ]; then echo 'A skill folder named frontend-security already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/enowdev/enowxcli' "$d" && git -C "$d" checkout --quiet '38293fe1b096e6bf3646c7344c38786ed688f464' -- 'crates/enowx-core/skills/frontend-security' && mkdir -p ~/.agents/skills && cp -R "$d"/'crates/enowx-core/skills/frontend-security' ~/.agents/skills/'frontend-security' && 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/'frontend-security' ~/.claude/skills/'frontend-security' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
