Amanda Caswell Builds 1 Routing AI to Manage 5 Specialist ChatGPT Agents

Caswell says a single routing agent became the most useful tool in her workflow by deciding which specialist GPT should handle each new task.
Five specialist agents — research, brainstorming, fact-checking, editing and review — had made her ChatGPT setup productive but cluttered, forcing an extra decision at the start of every project.
Her routing GPT evaluates each request against 5 questions: the goal, best specialist, whether multiple agents are needed, their order and what information is missing.
The setup starts with identifying 3 to 5 repeat tasks, building one custom GPT for each, then adding a router that can also absorb new specialists such as SEO, coding or image-generation assistants.
Caswell says the approach mirrors multi-agent AI systems like Sakana while keeping everything on one platform, aiming to make workflows smarter without adding complexity.
