Summary

  • Opt-in monocode.alwaysShowUsage pins Claude Code, Codex, Cursor, and Grok usage chips so switching to a provider MonoCode cannot read does not empty the footer. Default is off; with it off the bar still follows the active session.
  • Cursor usage is read from the signed-in Cursor.app session (usage-summary) using Auto/API percents, not used/limit cents. Grok usage is read from the Grok CLI session (billing?format=credits). Tokens never leave the host process.
  • OpenCode is left off the roster: Go’s usage endpoint 403s without a Go subscription, and Zen has no public quota API. Those sessions keep the existing session label.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 6ba2b

GitLab work-item content can influence agent instructions without an isolation boundary, which may lead to unintended actions from untrusted issue text. This should be resolved or explicitly accepted before merge.

@hardbeat920 I don't have OpenCode Go at the moment, and I already spent too much with AI this month. So, if you have it and can help finishing that up is good, otherwise we can do it later.

Return None when SQLite blob bytes are not ASCII UTF-16LE so even-length
UTF-8 JWTs fall through to the UTF-8 path instead of mojibake. Share the
duplicated invoke status handling across Claude, Cursor, and Grok fetchers.

Looks great overall. One concern: UsageFooter is unmounted when opening Settings, Search, Inbox, or Notes, so closing those views resets its cache and immediately polls the providers again.

Multiple windows also create separate pollers, while the Codex probe uses a shared child ID.
Could we move the polling/cache to an app-wide service so requests are deduplicated across remounts and windows?

Replace the even-length check and UTF-16 chunking with is_multiple_of
and as_chunks, and push a char when padding JWT payloads.

Move cache and polling into a module store so opening Settings, Search,
Inbox, or Notes no longer drops snapshots or immediately re-fetches.
Share the cache through localStorage so extra windows skip duplicate
Codex probes while another fetch is in flight.

75-82: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Consider asserting the persisted cache in this test.

The second round passes because the module-level snapshot is never cleared between stop() and the re-subscribe. resetRateLimitsStoreForTests is not called in between. The test therefore proves that the in-memory snapshot survives an unsubscribe. It does not exercise writeCache or readCache, so it would still pass if the localStorage write were broken.

Add an assertion on RATE_LIMITS_CACHE_KEY after the first round, or reset the store between rounds so hydration supplies the value.

190-199: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Stop polling when no listeners remain. UsageFooter unmounts for search, inbox, notes, and settings, but its cleanup only removes the listener. The retained wanted roster can therefore trigger visible provider fetchers every 15 minutes with no consumer. Keep the snapshot and cache; the next subscription restarts the poll and preserves the remount cache behavior.

Clicking refresh while a background fetch is running now waits for that
fetch and then refetches, instead of returning the stale poll.
