Port Check

Check if services are responding on given host:port pairs. Supports TCP and HTTP checks with configurable timeout. Use for service monitoring, health checks,...

This skill appears to do exactly what it says: run TCP and optional HTTP checks against host:port pairs using nc and curl. Before installing, review the provided script (already included) and confirm you are comfortable allowing network probes from the agent. Network scanning can be sensitive in corporate or external contexts—if you want to avoid accidental scanning, keep the skill user-invocable only (do not allow wide autonomous invocation) or run it in an environment with restricted network access.

Type: OpenClaw Skill Name: port-check Version: 1.0.0 The `scripts/port-check.sh` skill executes `nc` and `curl` with user-controlled `host`, `port`, and `timeout` values. While the skill's stated purpose is benign (network port checking), the direct use of powerful network utilities with unsanitized user input creates a risk of Server-Side Request Forgery (SSRF) if the agent has access to internal networks. There is no evidence of intentional malicious behavior like data exfiltration or persistence, but the lack of robust input validation for network targets makes it a high-risk capability.
