What does gmgn-portfolio do?
gmgn-portfolio is a skill that analyzes crypto wallets through the gmgn-cli tool on Solana, BSC, Base, Ethereum and several other chains. It first runs gmgn-cli config --check and, if no key is set, asks you for a GMGN API key. Subcommands return a wallet's holdings with profit and loss, transaction activity, 7 or 30 day stats such as win rate, batch profit for up to 100 wallets, a single token balance, and the tokens a developer wallet has created with their peak market cap. Claude turns the raw JSON into tables and summaries, following field notes that explain each number and how to back off from rate limits.

- You want to judge a wallet before copy-trading it
