🐮 Mooter — Cost Cockpit for Claude Code

See what your Claude Code routing actually saves you. Mooter routes each prompt to the cheapest capable model — local Ollama for trivial work, Haiku / Sonnet / Opus only when needed. This extension is the read-only cockpit for that engine: live savings, the tier mix, and every decision with its why.

Features


💸 Saved vs all-Opus	Real $ counterfactual computed from your own routing decisions — labelled token-estimated/advisory, never inflated.
📊 Tier mix	How much went local (T0 · free) vs Haiku / Sonnet / Opus, at a glance.
🧾 Decisions feed	Every prompt's tier, model, confidence and escalation rule — expand any row for detail.
🐄 Herd	Live agent run, swimlanes, and a tokens × LLM × agent matrix when you spawn work.
🩺 Doctor	Engine, tracker and pipeline health, with one-click fixes.
✱ Pairing	Detects the official Claude Code extension and shows the pairing in the header.

Requirements

The mooter engine — install once with npx @mooter/cli (see mooter.ai).
The official Claude Code extension (recommended — enables one-click sessions and pairing).
Optional: Ollama for the free local (T0) tier.

Until the engine is installed, the cockpit shows a short setup wizard instead of data.

How it works

Mooter is a hook, not a proxy — it never intercepts your API traffic and never touches your code. The engine writes local routing telemetry under ~/.claude/tools/router; this extension only reads that telemetry and talks to the engine's local savings tracker on 127.0.0.1. Nothing is sent anywhere by the extension.

Privacy

Read-only and fully local. No accounts, no network calls from the extension beyond localhost, no analytics. Works in Restricted Mode; needs a local filesystem (so not in virtual/web workspaces).

Settings

mooter.trackerPort — port of the local savings tracker (default 7821).
mooter.statusBar.enabled — show the 🐮 status-bar item (default true).

Cross-platform

macOS, Windows and Linux. With Remote/WSL/Codespaces the extension runs where your router lives (extensionKind: workspace).
