  Use when the user asks about crypto, DeFi, blockchain, or onchain data and
  you don't already have a tool installed for the task. Covers: token prices,
  market data, portfolio tracking, wallet balances, DeFi positions, yield
  strategies, DEX trades, NFTs, transaction history, smart contract analysis,
  security audits, cross-chain bridging, oracle workflows, tx simulation, and
  smart money analytics. This skill is a registry — it tells you which tool to
  install (MCP server, skill, plugin, CLI, or llms.txt) for the job.
