Onchain CLI

**Judgment:** Onchain CLI is a strong, purpose-built skill for crypto data, CEX accounts, onchain analysis, and prediction markets, with excellent agent integration via consistent JSON output and clear command semantics. **Key strengths:** - Rich functionality spanning spot prices, gas, wallets, portfolios, CEX history, transactions, and Polymarket. - Designed for automated use: `--json`, documented exit codes, and example jq pipelines. - Good UX for setup (`onchain setup`, `onchain test`) and flexible configuration (saved wallets, Polymarket tag filters). **Risks / limitations:** - Heavily dependent on third-party APIs (DeBank, Helius, Etherscan/Solscan, CEX APIs, CoinGecko), so failures, rate limits, or misconfiguration can degrade reliability. - Handles sensitive financial and account data; agents must avoid leaking API keys or raw private portfolio details to unintended recipients. - Only partial functionality works without configuration (primarily price/markets via CoinGecko), which may surprise users if not explained. **Recommended scenarios:** - Any user query about crypto prices, wallet balances, DeFi portfolio value, CEX holdings/history, gas prices, or transaction details on supported chains. - Questions about Polymarket markets, trends, and sentiment where structured prediction data is needed. - Agent workflows that need standardized JSON crypto data rather than ad-hoc explorer scraping or direct API integration.
