Aren't you tired of repeating that prompt over and over? Become the Master Chef on your dev team with goose recipes:
🍳 Pick and pair the right LLM per task
🌶️ Sprinkle in retry logic
🥣 Fold in template control flow
👨🏻🍳 Whip up parallel subrecipes

Why babysit every prompt when Goose can handle the queue?
Skip the messy one shot prompts. Queue digestible steps and let Goose run them in order. You can even reorder the prompts mid flow!
That means clearer results for Goose and more time for you to grab a coffee ☕️
The future of developer workflows is conversational!
Use the @Vercel MCP with goose to track projects, deployments, and team status!
