CLAUDE.md

TokenTracker CLAUDE.md is an instructions file for Claude Code from xiufengsun/TokenTracker. It costs 5,321 tokens per session, scanned A, original, MIT.

A project instruction file for Token Tracker, a local application that records AI token use through a command-line tool, web dashboard, and desktop apps.

In plain words
What is it for?
Use it when working on the tracker’s command-line interface, dashboard, local server, macOS app, Windows app, packaging, or deployment.
Why use it?
It explains the repository layout, build commands, and conventions so coding agents know where changes belong across its Node.js, React, macOS, and Windows parts.

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is xiufengsun/TokenTracker's own configuration. It tells Claude Code how to work on TokenTracker itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything TokenTracker configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

TokenTracker CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project shape

Token Tracker is a local-first AI token usage tracker.

  • CLI (src/, CommonJS, Node ≥20) — entry bin/tracker.js → src/cli.js. serve runs a local HTTP server on :7680, sync parses logs into ~/.tokentracker/queue.jsonl.
  • Dashboard (dashboard/, React 18 + Vite 7 + TS strict + Tailwind) — built to dashboard/dist/, served by the CLI locally and by Vercel at www.tokentracker.cc.
  • macOS app (TokenTrackerBar/, Swift 5.9, XcodeGen) — menu bar + WidgetKit. EmbeddedServer/ bundles the CLI runtime + built dashboard so the .app is self-contained.
  • Windows app (TokenTrackerWin/, .NET 8 WinForms + WPF + WebView2) — system-tray counterpart of the macOS app. Launches the bundled CLI serve on a dynamic loopback port (avoids the DoSvc-held :7680), hosts the dashboard in WebView2, registers the tokentracker:// deep-link for OAuth. Built EmbeddedServer/ (Node + CLI + dashboard) is bundled by scripts/bundle-node.ps1 so the .exe is self-contained. Dashboard adaptations are gated behind isNativeWindowsApp() (dashboard/src/lib/native-bridge.js) so macOS/web paths are untouched.

Data flow: AI CLI runs → hook fires → rollout.js parses → queue.jsonl → local API → dashboard.

For the canonical list of supported providers, grep parse*Incremental in src/lib/rollout.js — the source of truth, not this file.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
