claude.sh

A developer published a Bash launcher script, claude.sh, that routes Anthropic's Claude Code CLI between Google Vertex AI and an internal "dogfood" AI gateway. The script selects a route via the first argument, expands shorthand flags such as -c, -r, and -y into their full Claude Code equivalents, and passes any remaining arguments through to the CLI. It sets the appropriate environment variables for each backend, unsetting Vertex-specific settings when using the gateway, and defaults to the dogfood route.
