Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

RPC Health Check Skill

블록체인 RPC 노드 상태 점검 skill.

Safety: READ-ONLY

read-only JSON-RPC 메서드만 사용. 허용: eth_* 조회, net_*, web3_*. 금지: eth_sendTransaction, eth_sendRawTransaction 등 쓰기 메서드.

Arguments

$ARGUMENTS = 체인명 또는 RPC endpoint URL. URL이면 직접 사용, 체인명이면 endpoint 확인 요청.

Workflow

모든 호출: curl -s -X POST -H "Content-Type: application/json" -d ''

| 단계 | method | 확인 사항 | |------|--------|-----------| | 연결 | eth_chainId | 응답 없으면 DOWN, chainId로 네트워크 확인 | | 동기화 | eth_syncing | false=완료, {currentBlock,highestBlock}=진행중(진행률 계산) | | 블록 높이 | eth_blockNumber | hex→10진수 변환, 공개 레퍼런스와 비교 | | 피어 | net_peerCount | 0=네트워크 격리(심각), 소수=Warning | | 추가 | eth_getBlockByNumber ["latest",false], eth_gasPrice | 최신 블록 timestamp 뒤처짐 확인 |

Health Status 판정

| 상태 | 조건 | |------|------| | HEALTHY | syncing=false, 블록 차이0 | | WARNING | 블록 차이 5-50 또는 peers50, syncing=true, peers=0 | | DOWN | 연결 실패, timeout, 에러 응답 |

Multi-endpoint 비교시 테이블(Endpoint/ChainID/BlockHeight/Sync/Peers/Status)로 출력.

Troubleshooting

  • 응답 없음: TCP 접속 테스트, RPC 포트(8545/8547) 확인, 방화벽/SG
  • 동기화 멈춤: 피어 수 → 0이면 부트노드/네트워크, 디스크 공간, 블록 timestamp
  • 블록 높이 차이: syncing 여부, 하드웨어 IOPS/CPU, 체인별 동기화 시간

Output

hex→10진수 변환. 레퍼런스 비교. HEALTHY/WARNING/CRITICAL/DOWN 명시. 에러 굵게.
