Adds TokenWise under `### Development & Code Tools` — a Claude Code skill that auto-routes subtasks across Haiku, Sonnet, and Opus based on task class, logs every routed task with real $ numbers, and A/B tests cheaper tiers before trusting them.
Added alphabetically between `test-driven-development` and `using-git-worktrees`.
``` TokenWise Session Report — 47 tasks · 2h 14m
Haiku 32 tasks → $1.62 Sonnet 12 tasks → $2.06 Opus 3 tasks → $1.43
Total: $5.11 Baseline: $24.93 (all-Opus) Saved: $19.82 (79.5%) ```
Fits naturally alongside other Claude-Code-focused dev tools (lean-ctx, great_cto, etc.). The only entry that routes + measures + proves savings in one skill.
``` /plugin marketplace add CodeShuX/tokenwise /plugin install tokenwise@tokenwise ```
Then `/tokenwise:install` (with `--dry-run` available) walks the user through routing setup with diff preview and automatic backups.
