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 | $0.00410 | $0.00410 |
| Opus 5.5 | $0.00164 | $0.00164 |
| Sonnet 5.5 | $0.00082 | $0.00082 |
| Haiku 4.5 | $0.00041 | $0.00041 |
Grade A, and why
codex-status-menubar AGENTS.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 2mo 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.
What it actually says
Codex Status Menubar Agent Guide
Project Overview
Codex Status Menubar is a small native macOS Swift/AppKit utility that monitors local Codex Desktop session state and renders a read-only status view in the menu bar.
Repository Layout
CodexStatusApp.swiftcontains the full app, collector, detector, menu UI, CLI mode, desktop widget, and Pet-style stop bubble.run.shcompiles and runs the binary for development.install-desktop-launcher.shbuilds a minimal.appbundle and copies it to the Desktop.fixtures/contains sanitized Codex-home fixtures for CLI verification.scripts/verify.shcompiles the app and checks fixture statuses.launcher/Codex Status.app/Contents/Info.plistis the app bundle template.
Development Rules
- Keep the app external and read-only.
- Do not modify
Codex.app, Pet files, bundled Codex files, or real Codex state. - Treat Codex JSONL schemas as unstable.
- Ignore malformed JSONL lines.
- Keep fixture data synthetic and sanitized.
- Do not commit
.swift-module-cache/, generated binaries, generated app executables, or local reports. - Keep
CodexStatusApp.swiftsingle-file unless there is a clear reason to split it.
Verification
Run before publishing or opening a pull request:
./scripts/verify.sh
For local diagnostics:
./run.sh --once --debug
CODEX_HOME=fixtures/thinking ./run.sh --once --debug
Release Expectations
./scripts/verify.shpasses on macOS.plutil -lint "launcher/Codex Status.app/Contents/Info.plist"passes.git status --shortis clean.- Generated files are ignored.
- No real Codex logs, prompts, responses, credentials, or local private paths are committed.
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.
