My Cursor Custom Mode Setup: Building the Perfect AI Development Toolkit

Originally published on Towards AI.
Stop using generic AI chat. I’ve built a specialised toolkit in Cursor using GPT-5, Claude 4, and Gemini 2.5 to match the right model to the right job. Here’s the entire setup.
I got tired of the one-size-fits-all approach to AI in my IDE. Just having a single chat window feels like hiring a brilliant intern and asking them to be a senior architect, a QA lead, and a security expert all at once. It just doesn’t work. The real leverage comes from specialization.

The article discusses the author’s creation of a specialized AI development toolkit using various advanced models to improve coding efficiency and effectiveness in the IDE. It emphasizes the advantage of utilizing distinct AI assistants for specific tasks, rather than relying on a generic AI chat approach. The author elaborates on several modes within their AI toolkit, which focus on tasks such as architecture, debugging, optimization, testing, and more, highlighting how these modes can enhance a developer’s overall workflow and productivity. The author concludes by promising a follow-up post that will introduce additional AI assistants, emphasizing the growing importance of these tools in modern development environments.
