Sequential Thinking

secondsky/claude-skills

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.

  • Problem requires multiple interconnected reasoning steps
  • Initial scope or approach is uncertain
  • Need to filter through complexity to find core issues
  • May need to backtrack or revise earlier conclusions
  • Want to explore alternative solution paths

Don't use for: Simple queries, direct facts, or single-step tasks.
