|  | #!/usr/bin/env bash | 
|  | # claude launcher — route to either Vertex or the dogfood gateway. | 
|  | # Usage: | 
|  | # ./claude <route> [shortcuts...] [extra claude args...] | 
|  | # | 
|  | # Routes: | 
|  | # vertex route via Google Vertex | 
|  | # dogfood route via dogfood AI gateway (default) | 
|  | # | 
|  | # Shortcuts (expand to claude flags; combine freely, any order): | 
|  | # -c \| continue \| --continue -> --continue | 
|  | # -r \| resume \| --resume -> --resume | 
|  | # -y \| yolo \| dangerous -> --dangerously-skip-permissions | 
|  | # | 
|  | # Anything else is passed straight through to claude. | 
|  | # | 
|  | # Examples: | 
|  | # ./claude dogfood -c -y # gateway, continue last, skip permissions | 
|  | # ./claude vertex resume # vertex, pick a session to resume | 
|  | # ./claude -c # default route (dogfood), continue | 
|  | set -euo pipefail |
