New Plugin - Claude Code Usage

narlei

Hi Ulanzi team,
I built a small open-source plugin for Ulanzi Studio called "Claude Code Usage"
and would love your help getting it published in the marketplace.

What it does

Claude Code (Anthropic's coding agent) has a subscription with two usage limits:
a 5-hour rolling window and a weekly limit. The plugin shows both directly on
your Ulanzi Deck buttons — color-coded (green → yellow → orange → red) with a
"Reset in Xh" countdown — so you always know where you stand without having to
open the app.

How it works

- Two actions: "5-hour Limit" and "Weekly Limit".
- The plugin reads the user's existing Claude Code CLI OAuth token from the
  macOS Keychain (service: "Claude Code-credentials"). No API key required and
  no credentials are stored or transmitted by the plugin itself.
- It makes a minimal API call (1 token of Haiku, ~0.01% of weekly usage per
  day) every 5 minutes per button to read the standard
  "anthropic-ratelimit-unified-*" response headers.
- When the OAuth token expires, the plugin transparently delegates the refresh
  to the official `claude` CLI (no custom auth flow).
- Click the button to force an immediate refresh.

Requirements

- macOS only (the plugin reads from the macOS Keychain).
- Claude Code CLI installed (`brew install claude-code`) and signed in
  (`claude auth login`).
- Ulanzi Studio 3.0.11+.

Would you be able to review the submission and let me know if anything needs
to change before it can be published? Happy to make any adjustments you suggest.
Thanks a lot,
