robinebers/openusage is a native macOS menu-bar application that tracks usage of AI coding subscriptions, including limits, credits, and spending. Developers use it to monitor plans from services such as Claude, Codex, Cursor, and Copilot, while the catalogue entries support related workflows.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00054 | $0.00464 |
| Opus 5 | $0.00027 | $0.00232 |
| Sonnet 5 | $0.00011 | $0.00093 |
| Haiku 4.5 | $0.00005 | $0.00046 |
Grade A, and why
build-and-run-macos-app 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 10d 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
Build And Run macOS App
Create or update the project-local macOS build_and_run.sh script, then use
that script as the default build/run entrypoint.
Arguments
scheme: Xcode scheme name (optional)workspace: path to.xcworkspace(optional)project: path to.xcodeproj(optional)product: SwiftPM executable product name (optional)mode:run,debug,logs,telemetry, orverify(optional, default:run)app_name: process/app name to stop before relaunching (optional)
Workflow
- Detect whether the repo uses an Xcode workspace, Xcode project, or SwiftPM package.
- If the workspace is not inside git yet, run
git initat the project root so git-backed editor features unlock. - Create or update
script/build_and_run.shso it always stops the current app, builds the macOS target, and launches the fresh result. - For SwiftPM, keep raw executable launch only for true CLI tools; for AppKit/SwiftUI GUI apps, create a project-local
.appbundle and launch it with/usr/bin/open -n. - Support optional script flags for
--debug,--logs,--telemetry, and--verify. - Follow the canonical bootstrap contract in
../build-run-debug/references/build-script.mdfor the exact script shape. - Run the script in the requested mode and summarize any build, script, or launch failure.
Guardrails
- Do not initialize a nested git repo inside an existing parent checkout.
- Keep the no-flag script path simple: kill, build, run.
- Use
--debug,--logs,--telemetry, or--verifyonly when the user asks for those modes.
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.

build-and-run-macos-app is a skill published in the GitHub repository robinebers/openusage (4,079 stars, last pushed 3d ago), licensed MIT. It adds 54 tokens to every session and 464 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
