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

Hardens npm, pnpm, and Yarn v2+ projects against supply chain attacks. Audits package manager configuration, version pinning, and lockfile hygiene to protect the npm supply chain. Trigger with /supplychain:npm-harden or /supplychain:npm-harden <path>.

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/'npm-harden' ] || [ -L ~/.agents/skills/'npm-harden' ]; then echo 'A skill folder named npm-harden already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/eyesecurity/skills' "$d" && git -C "$d" checkout --quiet 'f5790eb83ab8f632ad86f456a485e0b2029a7a5d' -- 'plugins/supplychain/skills/npm-harden' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/supplychain/skills/npm-harden' ~/.agents/skills/'npm-harden' && 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/'npm-harden' ~/.claude/skills/'npm-harden' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
