94 / 100 · Low risk

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

By enowdev/enowxcli (GitHub) · coding · 67 stars · scanned at commit 38293fe

Security basics for a backend reachable from the internet: a checklist for every route, injection of every kind, SSRF with checks after DNS resolution, paths and uploads, secrets management, security headers with values, CORS and CSRF, rate limits and brute-force protection in a shared store, admin and debug endpoints, what never goes in a log, dependency scanning in CI. Read before shipping an endpoint that takes user input, files or URLs, or before a security pass.

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'backend-security' ] || [ -L ~/.agents/skills/'backend-security' ]; then echo 'A skill folder named backend-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 "$d" checkout --quiet '38293fe1b096e6bf3646c7344c38786ed688f464' -- 'crates/enowx-core/skills/backend-security' && mkdir -p ~/.agents/skills && cp -R "$d"/'crates/enowx-core/skills/backend-security' ~/.agents/skills/'backend-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/'backend-security' ~/.claude/skills/'backend-security' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
