Agent Integration

This CLI is designed for agent use. Key patterns:

1. Always use --json for programmatic access
2. Check exit codes - 0 for success, 1 for error
3. Use saved wallets - Configure once with onchain setup, reference by name
4. Rate limiting - APIs have rate limits, add delays between rapid calls

Example Agent Usage

# Get portfolio value
VALUE=$(onchain --json portfolio main | jq -r '.totalValueUsd')

# Get price with change
onchain --json price btc | jq '{price: .priceUsd, change24h: .priceChange24h}'

# Check if market is bullish
CHANGE=$(onchain --json markets | jq '.marketCapChange24h')

这个Skill功能非常丰富，涵盖了从代码生成到Bug诊断、测试、文档等编程全流程，文档详细（FAQ有672行），安全性检查也很全面。但正因如此，核心说明文件很大很复杂，新手容易迷路；而且很多高级功能需要额外配置才能用，不是装上就能上手。建议有一定基础的用户使用，或者愿意花时间仔细阅读文档再上手。
