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

By BankrBot/skills (GitHub) · coding · 1,213 stars · scanned at commit b440a49

Build onchain applications with React components and TypeScript utilities from Coinbase's OnchainKit. Use when users want to create crypto wallets, swap tokens, mint NFTs, build payments, display blockchain identities, or develop any onchain app functionality. Supports wallet connection, transaction building, token operations, identity management, and complete onchain app development workflows.

Works with any agent that supports SKILL.md skills.

Install

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

if [ -e ~/.agents/skills/'onchainkit' ] || [ -L ~/.agents/skills/'onchainkit' ]; then echo 'A skill folder named onchainkit already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/BankrBot/skills' "$d" && git -C "$d" checkout --quiet 'b440a49efee0c0b4cab6f6967232657a69810858' -- 'onchainkit' && mkdir -p ~/.agents/skills && cp -R "$d"/'onchainkit' ~/.agents/skills/'onchainkit' && 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/'onchainkit' ~/.claude/skills/'onchainkit' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
