Flexible Model Routing — Seamlessly toggle between flagship reasoning models, fast frontier tiers, or custom API endpoints depending on task complexity.

Tips & Best Practices

•
Project Rules (.cursorrules) — Create a .cursorrules file to prime the editor with framework conventions, preferred libraries, and code styling rules.
•
Precision Context Symbols — Use @Files, @Folders, @Docs, and @Web to feed targeted documentation and live references into your queries.
