Codex Rate Limit → IFTTT Notify

Fire a mobile push "codex rate limit detected" the moment an OpenAI Codex CLI run hits a rate/usage limit. This matters because the codex skills deliberately silently fall back to Opus and never surface the limit in the terminal — so a phone push is the only way the user learns Codex is throttled.

How it's wired (usually automatic)

All rate-limit state, notification, and dedupe live in one script: $HOME/.claude/scripts/codex-rate-limit.js.

The companion codex skills (/codex-review, /codex-2nd) already run codex-rate-limit.js check-output after each Codex run. When it detects a limit it marks a lockout and fires the push — so for those skills the notification happens on its own. You do not need this skill for them.

When to invoke manually

Some Codex paths bypass codex-rate-limit.js entirely: /codex-imagegen, /codex:codex-rescue, and any ad-hoc codex exec you run directly. If Codex output on one of those paths shows a rate/usage limit, funnel it into the same script so both the push and the shared lockout happen:

node "$HOME/.claude/scripts/codex-rate-limit.js" mark

mark records a 60-minute lockout (so the companion skills also back off) and fires the deduped push. Prefer mark over a bare notification — a real limit should set the lockout.

Recognize a limit from these cues in Codex stdout/stderr:

• you've hit your limit
• rate limit / too many requests / 429
• usage limit / quota exceeded
• a reset time like resets 5pm

The script's automatic detection (check-output/check-stderr) matches the phrase patterns above but not a bare 429 or loose reset phrasings like resets in 40 min — so those can slip past even the companion skills, which is another reason to funnel a limit you spot into mark yourself.

Notify without a lockout / test the push

To fire the push without touching the lockout (e.g. a quick end-to-end test of the IFTTT wiring):

node "$HOME/.claude/scripts/codex-rate-limit.js" notify "test from codex-ratelimit-notify"

Check that the push arrives on the phone. Nothing else changes — Codex stays available. If the key isn't configured, it prints IFTTT_WEBHOOK_KEY not set — nothing sent. instead.

Mechanism

• Channel: IFTTT Webhooks event Claude Code (the same applet used by

  hooks/notify-ifttt.sh), key read from the IFTTT_WEBHOOK_KEY env var. If the key is unset on this machine, the notification is skipped silently.

• Payload: value1 = codex rate limit detected, value2 = reset detail (or, for the

  notify subcommand, the message you pass), value3 = current working directory.

• Dedupe: fires at most once per lockout window — a second codex skill hitting the same

  wall won't buzz the phone again until the lockout expires.

• Best-effort: a failed webhook never breaks rate-limit tracking.
