Sequential Thinking

This gives Claude a structured way to think through complex problems step by step, with the ability to revise earlier conclusions or branch into alternative approaches. You'd reach for it when the problem requires multiple interconnected reasoning steps or when you're not sure of the full scope upfront. It's basically a formalized thinking protocol with parameters for thought sequence, revision tracking, and branch exploration. The dynamic scope adjustment is nice since you can start with a rough estimate and refine as understanding evolves. If you're already breaking down a problem naturally, this codifies that process. If you're not, it might feel like overhead for straightforward tasks.
