Routes Claude Code subtasks to Haiku/Sonnet/Opus per task class, logs every routed task with real token and cost numbers, and A/B tests cheaper tiers before trusting the savings.

A Claude Code skill that auto-routes subtasks to the cheapest model that can handle them (Haiku for grunt work, Sonnet for scoped reasoning, Opus only for synthesis), then logs every routed task to a local NDJSON with real token + cost numbers. Includes an A/B test subcommand that runs the same task across multiple tiers and scores quality, so the routing decisions are verified against the user...
A Claude Code skill that auto-routes subtasks to the cheapest model that can handle them (Haiku for grunt work, Sonnet for scoped reasoning, Opus only for synthesis), then logs every routed task to a local NDJSON with real token + cost numbers. Includes an A/B test subcommand that runs the same task across multiple tiers and scores quality, so the routing decisions are verified against the user's real workload — not estimated.
Anthropic's own bug tracker (Issue #27665) reports 93.8% of Max-subscriber Claude Code tokens flow to Opus. Existing routers (claude-router, wshobson, VoltAgent) either pin models statically or route by vibes-based heuristics with no measurement. TokenWise fills the measurement gap.

|---|---|---|
| Mechanical | Haiku 4.5 | file reads, grep, format, rename, simple edits, doc lookups |
| Scoped reasoning | Sonnet 4.6 | single-file refactor, scoped research, test writing |
| Synthesis | Opus 4.7 | architecture decisions, multi-file refactor, security review |
Safety caps:
Zero telemetry. All logs in .tokenwise/log.ndjson local to the project. Task descriptions truncated to 80 chars and stripped of file contents before logging. No analytics endpoint exists in the source.
In any Claude Code session:
/plugin marketplace add CodeShuX/tokenwise
/plugin install tokenwise@tokenwise
Then run /tokenwise:install and follow the guided prompts.
model: param has known silent-fail bugs on some Claude Code builds — skill probes for this at install and refuses to configure if routing is brokennpx claudepluginhub sickn33/antigravity-awesome-skills --plugin antigravity-bundle-aas-mobile-app-builderRoutes Claude Code subtasks to the cheapest suitable model (Haiku/Sonnet/Opus) per task class, logs real token costs, and A/B tests tiers to validate savings.
Optimizes Claude Code costs: track tokens and USD with /cost, route models (Haiku/Sonnet/Opus), reduce via /compact/grep/sub-agents, maximize prompt caching.
Enforces concise responses and smart model routing to cut Claude Code costs 30-60% while preserving technical accuracy. Auto-activates on budget/cost mentions or via /cost-mode.
