For a Clash node, look at the egress before the score
Use EgressScope to see a Clash node's public egress and quality score. It does not read your local config, and it does not replace the client's own connectivity probe.

Two ways to check
When the browser is using that node, open the home page for the domestic / overseas egress and the quality score.
If you already know the node's public IP, pass it to the health-check API. Scripts should read score and choose their own threshold.
Don't mix these up
A client health check mostly says whether the node connects. Low latency is not a high quality score, and a reachable URL does not mean split rules are doing what you think.
This site does not log in to Clash and does not read the config file.
