+## Proxy Configuration
+
+If you need a proxy to access Google services (e.g., in China), set `HTTP_PROXY` and `HTTPS_PROXY` environment variables before running:
+
+```bash
+# Example with local proxy
+HTTP_PROXY=http://127.0.0.1:7890 HTTPS_PROXY=http://127.0.0.1:7890 npx -y bun ${SKILL_DIR}/scripts/main.ts "Hello"

+HTTP_PROXY=http://127.0.0.1:7890 HTTPS_PROXY=http://127.0.0.1:7890 npx -y bun ${SKILL_DIR}/scripts/main.ts --login
+```
+
+**Note**: Environment variables must be set inline with the command. Shell profile settings (e.g., `.bashrc`) may not be inherited by subprocesses.
