Read remaining Claude Code and Codex subscription quota without spending it. Use when the user asks or after a vendor rejects work for quota; a caller such as rotate-agent may also arm a scheduled read on purpose. Never poll on your own; after a `wait` verdict, pass the reset wait to `sno heartbeat` and re-read once when it ends.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# subscription-quota-check ## The one rule **Read it on demand: when the human asks, or when something was actually blocked.** This skill is not a monitor and never schedules a read of its own, apart from the single re-confirmation read after a `wait` verdict (see "When it says wait"). The Claude usage endpoint is itself rate limited, so a probe on a timer eventually earns a 429 and starts serving cached numbers — a checker that reports confidently while reading nothing. A caller such as rotate-agent may arm a scheduled read deliberately; that is the caller's decision, and the rate-limit risk is then the caller's to manage. Outside such an armed schedule, every run must trace to one of the two moments above. The anti-pattern it replaces has a name: **finding out you are out of quota by making a real call and reading the error.** That spends quota to learn you have none, and the error does not say when it comes back. This reads the same state for free and tells you the reset time. ## Running it Use the command installed by `sno setup`, with the installed `sno heartbeat` command for the wait branch. If a command names a missing prerequisite, install that …

How to install
mdr add sno-ai/sno-station-skills/subscription-quota-check@sha256:d898e2ed39aefcd8The line at the top of this page pins the label git:20261007.9784a78, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
