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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.13451 | $0.13451 |
| Opus 5.5 | $0.05380 | $0.05380 |
| Sonnet 5.5 | $0.02690 | $0.02690 |
| Haiku 4.5 | $0.01345 | $0.01345 |
Grade C, and why
TokenEater AGENTS.md scanned grade C with 1 finding 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 13d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

The opening of the file, as written. The whole thing — 305 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
TokenEater is a native macOS menu bar app, plus WidgetKit widgets and a floating overlay, that tracks Claude and OpenAI Codex usage limits in real time, as two equal providers. This file is the guide for contributors and AI coding agents: how the repo is laid out, how data flows, the rules that are easy to break, and the commands that build, test, and ship it.
It complements the other docs and deliberately does not duplicate them:
README.md- what the app does (full feature list), the security and privacy model, the Claude API calls and optional Codex usage call.CONTRIBUTING.md- contribution workflow, commit conventions, how to get help, the external-contributor signing caveat.SETUP.md- building from source as an end user.docs/TROUBLESHOOTING.md- common fixes and the canonical clean-reset script.docs/design/MASTER.mdanddocs/design/COLORING.md- the window design system and the Smart Color risk model.
Current version: 6.1.0 (MARKETING_VERSION in project.yml).
Language
- Everything on GitHub (issues, PRs, commits, branches) is in English.
- Conventional Commits are preferred (
feat:,fix:,chore:,docs:), since they make changelog generation easier. Don't stress about it; a wrong prefix can be fixed on merge.
Repo layout and targets
project.yml is the single source of truth for the project. The .xcodeproj is generated by XcodeGen and is gitignored. Never edit the .xcodeproj directly: those edits are lost on the next generate. To change targets, build settings, schemes, entitlements wiring, the installer prebuild step, or the version, edit project.yml then run xcodegen generate.
A stale
ClaudeUsageWidget.xcodeprojmay exist locally from before the rename. It is also generated and gitignored. Ignore it.
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.
