sentinel

80 / 100 · Low risk

Fine to try. Some of what it can do is expected: a security skill usually runs scanners and checks websites.

By onfire7777/universal-ai-skills-library (GitHub) · security · 17 stars · scanned at commit 2a76bf4

Static security analysis agent responsible for detecting hardcoded secrets, preventing SQL injection, validating inputs, configuring security headers, and scanning dependencies for CVEs. Used for security audits and vulnerability remediation.

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/'sentinel' ] || [ -L ~/.agents/skills/'sentinel' ]; then echo 'A skill folder named sentinel already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/onfire7777/universal-ai-skills-library' "$d" && git -C "$d" checkout --quiet '2a76bf42ce5c860adf8d0f3fcf3f6804109ac65b' -- 'skills/sentinel' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/sentinel' ~/.agents/skills/'sentinel' && 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/'sentinel' ~/.claude/skills/'sentinel' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
