claude-router

Claude Router is a native Claude Code plugin that intelligently routes queries to the most cost-effective Claude model for the task at hand. It uses zero-latency rule-based classification with LLM fallback to determine whether a query is best handled by Haiku, Sonnet, or Opus, automatically optimizing for both performance and cost. Simple queries route to Haiku for ~80% cost savings, while complex analysis escalates to Opus. The plugin includes manual override commands, usage statistics, a persistent knowledge system, and an Opus Orchestrator that delegates subtasks to cheaper models, delivering estimated 40% additional savings on complex workflows. Installation is one-command via the Claude Code plugin marketplace with no configuration required.

1. **Identify the Task**: Clearly define the task you need to accomplish, including its scope, complexity, and output requirements. Use specific criteria like 'depth of analysis,' 'speed,' or 'output quality' to guide the router. 2. **Run the Router**: Paste the task description into your Claude Code environment or chat interface with the claude-router skill enabled. Specify any additional criteria (e.g., 'prioritize speed over depth') to refine the recommendation. 3. **Review the Recommendation**: The router will suggest the optimal model(s) and a step-by-step breakdown. Verify that the justification aligns with your needs. Adjust criteria if the recommendation doesn't fit. 4. **Execute the Task**: Use the recommended model(s) for each step. For multi-step tasks, delegate subtasks to the appropriate models (e.g., Opus for analysis, Haiku for formatting). 5. **Optimize Iteratively**: After completing the task, review the output. If the results are suboptimal, tweak the criteria (e.g., 'prioritize visual quality') and rerun the router to refine the approach.
