Skill: Agent wallet readiness check

Bundled execution of the Agent wallet readiness check workflow - One call answers 'can this wallet pay right now?' - USDC balances on Base AND Solana, live Base gas, and a ready-to-share Coinbase Onramp funding link if it's running dry. One x402 payment runs 3 underlying tools (wallet-balances, gas-snapshot, onramp-link); partial-success per step.

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

const client = new x402Client();
