## Tools (as reported by the server, not verified)

- `audit\_repo\_token\_waste`: Static-analyze a public GitHub repo \(owner/name\) or a set of source files for LLM token waste: uncached static prompts, frontier models on extraction tasks, hot loops, non-deterministic repeat calls. Returns findings with fixes and an estimated recoverable percentage.
- `optimize\_prompt\_payload`: Rewrite an OpenAI Chat/Responses or Anthropic Messages request body so its static prefix is provider-cacheable \(Anthropic cache\_control breakpoints, OpenAI prompt\_cache\_key\). Returns the optimized body, what changed, the token profile and the projected per-request saving. Never changes the tokens th
- `calculate\_model\_arbitrage`: Price a workload at list prices across models: cost per request and per month for the requested model, its cheaper sibling, and the effect of prompt caching. Pricing table version 2026-10-26.
- `provision\_workspace`: Create a TokenZero workspace and key with no form. Returns the key once, the base URLs that route through it \(OPENAI\_BASE\_URL / ANTHROPIC\_BASE\_URL\), the one-click dashboard link and the badge URL. Free up to the monthly free tier; nothing is billed.
- `workspace\_metrics`: Live value scorecard for a TokenZero workspace: hard savings and net ROI per window, the four engines' contribution, speed, parity, availability and privacy posture, per-model breakdown and one-click recommendations. Needs the workspace key \(tz\_live\_…\); pass demo: true for a labelled sample.
