Why is Claude Sonnet considered the best default model?

Sonnet offers an ideal balance of nuanced reasoning and speed, making it suitable for most feature implementations, debugging, and code reviews.

Is Claude Opus required for standard refactoring?

Usually, no. Opus is reserved for deep architectural design, complex system-wide implications, and tasks where absolute correctness is critical and highly complex.

How does the decision algorithm work?

It first checks for Opus indicators (architecture/design), then Haiku indicators (simple lookups/scans), and defaults to Sonnet for everything else.

When should I use Claude Haiku for coding tasks?

Use Haiku for simple lookups, file listing, pattern matching, and basic syntax validation where speed and low cost are the primary goals.

生産性とワークフロー

Optimizes task efficiency by selecting the most appropriate Claude model based on complexity, cost, and speed requirements.

The Model Selection skill provides a robust framework for determining whether to use Claude Haiku, Sonnet, or Opus for any given development task. By analyzing specific prompt indicators—such as 'architect' for high-level design or 'find' for simple searches—this skill ensures that resources are used efficiently. It helps developers manage subagent routing, reduce API costs for simple lookups, and ensure that high-reasoning capabilities are applied only when necessary for complex architectural decisions or novel algorithm development.
