Copy the pinion-openclaw-skill/ directory into your OpenClaw workspace skills/ folder:
cp -r pinion-openclaw-skill ~/.openclaw/workspace/skills/pinion-chain-intel
Or install from the repo:
git clone https://github.com/chu2bard/pinion-os.git
cp -r pinion-os/pinion-openclaw-skill ~/.openclaw/workspace/skills/pinion-chain-intel
OpenClaw loads skills from workspace/skills/ on the next session. The 8 individual SKILL.md files tell the agent what each skill does, how to call it, and what to expect back.
npm install pinion-os
import { PinionClient } from "pinion-os";
const pinion = new PinionClient({ privateKey: process.env.PINION_PRIVATE_KEY });
const balance = await pinion.skills.balance("0x101C...");
const price = await pinion.skills.price("ETH");
const chat = await pinion.skills.chat("what is x402?");
