nodejs-keccak256

95 / 100 · Low risk

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

Prevent Ethereum hashing bugs in JavaScript and TypeScript. Node's sha3-256 is NIST SHA3, not Ethereum Keccak-256, and silently breaks selectors, signatures, storage slots, and address derivation.

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/'nodejs-keccak256' ] || [ -L ~/.agents/skills/'nodejs-keccak256' ]; then echo 'A skill folder named nodejs-keccak256 already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/tensology/decisionsai' "$d" && git -C "$d" checkout --quiet '2d78e202be99a190b87417938f804eded81687da' -- 'plugins/ecc/skills/nodejs-keccak256' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/ecc/skills/nodejs-keccak256' ~/.agents/skills/'nodejs-keccak256' && 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/'nodejs-keccak256' ~/.claude/skills/'nodejs-keccak256' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
