Steps

Use the Read tool to read ~/.claude/router-stats.json
If the file doesn't exist, inform the user that no stats are available yet
Calculate percentages for route distribution
Display exception counts if present (router_meta queries are handled by Opus despite classification)
Format and display the statistics
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.

How to use it

Copy the folder

Take aiskillstore/router-stats from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
