What this skill does
Router Stats Display usage statistics and estimated cost savings from Claude Router. Instructions Read the stats file at ~/.claude/router-stats.json and present the data in a clear, formatted way. Data Format The stats file contains (v1.2 schema): Output Format Present the stats like this: Steps 1. Use the Read tool to read ~/.claude/router-stats.json 2. If the file doesn't exist, inform the user that no stats are available yet 3. Calculate percentages for route distribution 4. Display exception counts if present (routermeta queries are handled by Opus despite classification) 5. Format and display the statistics 6. Include the savings comparison explanation Notes Savings are calculated assuming Opus would have been used for all queries Cost estimates use: Haiku 4.5 $1/$5, Sonnet 4.5 $3/$15, Opus 4.5 $5/$25 per 1M tokens Average query estimated at 1K input + 2K output tokens Exceptions: Queries about the router itself are classified but handled by Opus (per CLAUDE.md rules). This is intentional - users discussing the router get the most capable model while still seeing what the classifier decided.
