Replay Doctor

See what your AI agent actually spent. Replay reads the transcripts Claude Code and OpenAI Codex already keep on disk, reconstructs token usage and cache behavior, and names the turn a prompt cache broke and what it cost. It reproduces the provider's own cache reads before reporting anything, and prints NOT MEASURED where the evidence is absent instead of guessing. Built to measure GPT-6 Astra. Not measured yet. Single Go binary, zero third-party dependencies, no account.
