Ai Usage Inspector

---

Your coding agent spends tokens on every prompt. This records what each one actually cost — locally, in the project it happened in — and gives that project its own dashboard.

It tracks **Claude Code**, **OpenAI Codex**, **Cursor**, **OpenCode**, and the VS Code agents **Cline**, **Roo Code**, and **Kilo Code**, and normalizes them into one record shape so they sit side by side in the same table.

Two ways in, one way through: a live turn is captured the moment an agent stops, history already on disk is imported by sync, and both meet at the same ingest step.

Features

• Multi-agent, one table — seven agents side by side, with provider filters, badges, charts, and cost/token splits.
• Per-prompt detail — prompt and response text, input/output/cache/reasoning tokens, model, permission mode, context fill %, USD cost, duration, first-response latency, skills, and tool/subagent counts where the agent exposes them.
• Never blocks your agent — the hook spools the payload and exits; a detached worker does the parsing and writing.
• Yours, locally — records live in your project, tracking can be turned off per project, and
