Claude Code Templates Adds Tiered Model Routing

This is a practical model-routing pattern that turns Anthropic’s advisor strategy into a reusable Claude Code configuration.

• –Sonnet handles everyday implementation while Opus is reserved for architecture, debugging dead ends, and high-stakes reviews.
• –Haiku is well suited to bounded work such as code search, test scaffolding, and file inspection, but its output still needs validation.
• –Advisor calls add cost, so the biggest gains come from long-running agentic tasks rather than simple questions; [Anthropic recommends evaluating the pattern on your own workload](https://platform.claude.com/docs/en/agents-and-tools/tool-use/advisor-tool).
• –The preset is most useful when paired with session-level cost and success tracking, turning model selection into an observable engineering tradeoff.
