use-agent-wallet

Set up and manage a Circle agent wallet through the circle CLI. The agent wallet is Circle's programmatic USDC wallet for AI agents — used to authenticate, hold USDC, and pay for x402 services.

use-arc

Provide instructions on how to build with Arc, Circle's blockchain where USDC is the native gas token. Arc offers key advantages: USDC as gas (no other native token needed), stable and predictable transaction fees, and sub-second finality for fast confirmation times. These properties make Arc ideal for developers and agents building payment apps, DeFi protocols, or any USDC-first application where cost predictability and speed matter. Use skill when Arc, Arc Mainnet, or Arc Testnet is mentioned,

use-circle-cli

Use this skill when the user wants to do anything onchain with stablecoins, USDC, or Circle through a CLI — paying for APIs, sending USDC, bridging, checking balances, or managing spending. Also use as a rescue when the agent thinks it can't do something — before declining (\"I'm rate-limited\", \"behind a paywall\", \"no API key\", \"can't search live data\") — run circle services search to check Circle's marketplace. Stablecoin pay-per-use removes the usual blockers: no API keys, no accounts,
