tokencat 0.1.0

Local-first, read-only AI coding agent token and usage inspector.

TokenCat

TokenCat is a local-first, read-only CLI for understanding how AI coding agents are being used on your machine.

It scans local Codex and Gemini CLI logs, summarizes tokens, sessions, and models in one place, and can optionally estimate API-equivalent cost without touching your prompts, responses, auth credentials, or network endpoints.

Why TokenCat

• One dashboard for Codex, Gemini CLI, and Copilot CLI detection
• Read-only by design: no proxying, no request interception, no endpoint rewrites
• Local-first privacy defaults: no raw prompt/response output, no OAuth/session token access
• Useful in both human and script workflows: terminal dashboard by default, JSON when needed

Features

• Default 0-argument dashboard: tokencat
• Session-level and model-level usage views
• Daily usage breakdown with concrete model rows
• Local pricing catalog with optional refresh for cost estimation
• Stable anonymous session IDs by default
• Explicit diagnostics for unsupported or missing providers

Install

Python 3.11+ is required.

Install with pipx:

pipx install tokencat

Upgrade later with:

pipx upgrade tokencat

If you want to run from a local checkout instead:

pipx install .

For maintainers preparing a release from a local checkout:

make install-release
make release-check

Quick Start

Open the default dashboard:

tokencat

Inspect a longer time window:

tokencat --since 30d

Focus on one provider:

tokencat dashboard --provider codex

List recent sessions:

tokencat sessions --provider codex --limit 20

See model totals:

tokencat models --provider gemini

Check local provider detection:

tokencat doctor

Inspect pricing coverage:

tokencat pricing show

Refresh the local pricing cache:

tokencat pricing refresh

Commands

tokencat
tokencat dashboard --provider codex
tokencat summary --json
tokencat sessions --provider gemini --limit 20
tokencat models --since 30d
tokencat doctor
tokencat pricing show
tokencat pricing refresh

Common flags:

• --provider codex|gemini|copilot
• --since / --until with values like 7d, 24h, or ISO dates
• --json
• --no-price

Extra session flags:

• --limit
• --model
• --show-title
• --show-path

Supported Providers

Provider	Status	Notes
Codex	Supported	Reads ~/.codex/sessions/**/*.jsonl and ~/.codex/archived_sessions/*.jsonl, then falls back to ~/.codex/state_*.sqlite when needed.
Gemini CLI	Supported	Reads ~/.gemini/tmp/**/chats/session-*.json and non-sensitive settings metadata.
GitHub Copilot CLI	Detection only	Reports partial, unsupported, or not_found; does not treat editor plugin state as CLI usage telemetry.

Privacy

TokenCat is intentionally conservative.

• It only reads local files that already exist on your machine.
• It does not proxy traffic or intercept requests.
• It does not modify provider endpoints or sessions.
• It does not read OAuth credentials for reporting.
• It never outputs raw prompt or response bodies.
• It redacts sensitive local metadata by default.

By default, output does not include session titles, cwd paths, or raw session IDs. If you want more local detail in session listings:

tokencat sessions --show-title --show-path

Pricing

TokenCat can estimate API-equivalent cost for models with a known pricing entry.

• Pricing works offline by default using a bundled catalog.
• tokencat pricing refresh updates TokenCat's own local cache at ~/.tokencat/pricing/catalog.json.
• Unknown or old model names are shown as unknown instead of being guessed.
• Coverage is always shown so you can see how much usage was actually priceable.

Current pricing references:

• OpenAI API pricing
• OpenAI Codex pricing
• Gemini API pricing
• GitHub Copilot plans

JSON Output

All JSON commands keep a stable top-level shape:

• generated_at
• filters
• providers
• summary or items
• warnings

This makes TokenCat easy to use in scripts and local automation.

Scope and Limitations

• v0.1 is macOS-first.
• Linux path hooks are intentionally easy to extend, but Linux is not yet a polished support target.
• Windows is not yet supported.
• Copilot support is currently detection-only, not full usage accounting.
• Cost is an estimate, not your actual bill.
