Claude Code no longer hot-reloads the env configuration in settings.json after switching providers

Quick fix

Restart Claude Code after switching so it reads settings.json again; clash-for-ai can avoid this limitation.

Symptom

Section titled “Symptom”
Error output
现在切换后，`settings.json` 文件确实已更新，但 Claude Code 的 `/status` 仍显示旧的 URL，必须重启才能生效。
English translation

After switching, the settings.json file has indeed been updated, but Claude Code’s /status still shows the old URL. A restart is required for it to take effect.

Cause

Section titled “Cause”

The original issue comments state that Claude Code does not hot-reload settings.json: it reads this configuration only once at startup. Therefore, although cc-switch has updated the file, Claude Code in the current terminal window still shows the old ANTHROPIC_BASE_URL.

Fix

Section titled “Fix”

  1. After switching providers, restart Claude Code, then use /status to confirm whether the new ANTHROPIC_BASE_URL has taken effect.

  2. To avoid this limitation, the original issue comments recommend clash-for-ai; the reporter replied that this solution met their needs.
