Show usage for every saved Claude account in the tray

[Finesssee]

Fixes #787.

Summary

Claude showed usage only for the active account. Codex showed every logged-in account. This brings Claude in line.

• Rate-limit gate per account (usage_gate.rs). A 429 on one saved Claude account no longer blocks usage checks for the others. Each account keeps its own back-off and cached result.
• One account at a time, with the last result kept (commands/claude_usage.rs). Saved accounts are checked one after another, so they don't trigger rate limits together. The last good usage for each account is stored in account-usage-v1.json, so the tray still has numbers after a restart or a failed check. The file holds only percentages and reset times, never tokens.
• Tray rows (tray_accounts.rs, tray_bridge.rs). Each saved Claude account now shows Session and Weekly percentages in the tray, the same way Codex accounts do. A window whose reset time has passed is left out of the tray row instead of showing a stale number.

Provider data stays siloed. These rows use only Claude account data.

Commands run (merged with main 235ba9e, head b4a7297)

• cargo fmt --all -- --check: clean
• cargo clippy --manifest-path apps/desktop-tauri/src-tauri/Cargo.toml --all-targets -- -D warnings: clean
• cargo test --manifest-path apps/desktop-tauri/src-tauri/Cargo.toml: 689 passed, 0 failed (Simplify the Tauri shell crate and split its god files #796 removed duplicate shell tests on main)
• Earlier on this branch (head bc6aaad): cargo clippy --workspace --all-targets -- -D warnings clean; cargo test --manifest-path rust/Cargo.toml --no-fail-fast 4790 passed, 0 failed, 2 ignored. The later merges did not touch rust/.

There are no frontend changes.

Proof

• Desktop proof on a fresh tauri:build:debug of head b4a7297 (hybrid CDP + CUA). Details and screenshots description in the proof comment: 9 pass, 0 fail.
• Not covered by pixels: the native tray menu rows and the tray-side filter for windows past their reset. Those are covered by the tray_accounts unit tests.

Summary by CodeRabbit

• New Features
  • Claude session and weekly usage percentages now appear in account tray menus when available.
  • Claude account usage is saved between app launches and restored at startup.
  • Usage checks and temporary rate limits are tracked independently per account, so one account’s limit does not block checks for others.

📝 Walkthrough

Claude usage gates and cached responses are now account-scoped. The desktop loads and saves Claude usage state, and the tray displays available session and weekly usage percentages for Claude accounts.

Changes: Claude account usage

Layer / File(s)	Summary
Account-scoped usage gates rust/src/providers/claude/oauth/mod.rs, rust/src/providers/claude/oauth/usage_gate.rs	Usage gate checks, rate-limit blocks, and cached responses now use account-aware keys. Persisted state uses bounded per-account maps and handles legacy cache data.
Desktop usage cache and refresh apps/desktop-tauri/src-tauri/src/commands/claude_usage.rs, apps/desktop-tauri/src-tauri/src/main.rs	Startup loads a versioned usage cache. Refresh processes accounts sequentially, publishes current results for live accounts, persists the state, and triggers update and tray-rebuild notifications.
Claude tray usage rows apps/desktop-tauri/src-tauri/src/tray_bridge.rs, apps/desktop-tauri/src-tauri/src/tray_accounts.rs	The tray bridge passes account usage state to the Claude menu builder. Rows append available session and weekly usage percentages rounded to whole percentages.

Merge Risk: ⚪ Minimal · up to b4a72

The tray now shows Claude session and weekly usage per account and hides windows whose reset time has passed. No concrete merge-blocking risk remains in the reviewed changes.

Full details: Linked Issues check

Explanation

Issue #787 requires usage for multiple saved Claude accounts in the tray. refresh_claude_account_lanes checks accounts sequentially and stores state by account ID. UsageGate isolates rate limits and successful-response caches by account. prepend_account_menus adds Session and Weekly percentages from the matching Claude account state. The reported tests cover cache behavior, account isolation, and tray labels. The current head adds no change that removes this behavior.

Full details: Out of Scope Changes check

Explanation

The reviewed changes support issue #787. Sequential checks, per-account gate state, cache persistence, and tray updates enable multi-account Claude usage. The tray reads Claude account data only. The current incremental change only reuses a tray test helper. No unrelated change is established.

Full details: Provider Data Stays Siloed

Explanation

The change keeps Claude data within Claude paths. The tray bridge reads only AppState.claude_account_usage, and tray_accounts.rs passes it only to claude_accounts_menu; Codex and Grok menus do not receive it. The cache is stored at claude/account-usage-v1.json and is keyed by live Claude account IDs. The OAuth gate is under rust/src/providers/claude/, and its persisted keys are digests, not account identities. No changed shared code matches ProviderId values or adds cross-provider branching.

Full details: Secrets Handled Safely

Explanation

PASS. The changed account-usage cache stores only percentages, reset times, timestamps, account IDs, and generic sanitized error text. It uses secure_file::write_string and atomic replacement. OAuth tokens are used only to build hashed gate keys and the Authorization header; they are not logged, shown to users, or written by the changed code. No changed code deletes or overwrites another application's credential files or keyring entries.

Full details: No Unapproved Dependencies

Explanation

The pull request changes six Rust source files only. It does not modify any Cargo.toml or package.json, add npm or yarn lockfiles, or change the pinned pnpm packageManager version. No dependency addition is present.

Full details: Ui Changes Include Windows Proof

Explanation

The pull request changes visible tray rendering. The diff adds Session and Weekly percentages to Claude account labels in apps/desktop-tauri/src-tauri/src/tray_accounts.rs and passes usage state into the native tray menu in tray_bridge.rs. The PR description says fresh Windows tray proof is “pending” and is not attached. It provides no completed screenshot or proof note from a fresh Windows build.

Resolution

Attach screenshots from a fresh Windows build, or add a completed proof note that records the tray result from a fresh Windows build.

UI proof (hybrid CDP + CUA, build b4a7297)

Surface: Settings › Providers › Claude, "Claude Code accounts" section, on a fresh tauri:build:debug of this head. Change: last-known usage per saved Claude account is cached on disk and shown again after a restart.

Setup: isolated home with two fake saved Claude logins (proof.alpha@example.com, proof.beta@example.com, fake tokens) and a seeded claude/account-usage-v1.json in the format this build writes (A: Session 30% / Weekly 55% used; B: Session 90% used with a reset already past, Weekly 40%, last check failed). Every outbound request went to a dead proxy, so no refresh could succeed. The app ran on the secondary monitor and never took focus.

Result: 9 pass, 0 fail.

Check	Method	Result
Both saved accounts listed from the store	CDP get_claude_accounts_state + DOM	pass
Usage gated while "Allow reading Claude Code's credentials" is off	bridge usageError + DOM message	pass
Checkbox click persists the option	CDP click + get_settings_snapshot	claudeAllowReadingClaudeCodeCredentials: false → true
Cached per-account usage after opt-in	bridge	A 30% / 55%, B Weekly 40%
Cached usage rendered	DOM	A "70% left" / "45% left", B Weekly "60% left"
Cache file holds no credentials	file read	no tokens, no accessToken / refreshToken (1805 bytes)
Restart: cached usage restored at launch, while every refresh fails offline	relaunch + bridge + DOM	pass (A shows usage plus "Will retry automatically")
Window: visible, DWM dark under auto, not topmost	Win32/DWM	pass
Focus untouched	foreground HWND watch	pass

Screenshots (cua-driver, real pixels; synthetic example.com data only), kept locally because gh cannot upload images to a comment:

1. 910-01-gated: both accounts listed, each with "Enable Allow reading Claude Code's credentials in Settings to check saved accounts."
2. 910-02-usage: after opt-in, A shows Session 70% left (resets in 1h 59m) and Weekly 45% left; B shows Weekly 60% left; both show the failed-check note with the cached "Updated" time.
3. 910-03-restart: after a restart, the same cached numbers are shown before any successful refresh.

Not covered: the native tray menu rows, and the tray-side filter that leaves out windows past their reset. The Settings card still shows B's expired Session as "10% left · Resetting…". The filter applies only to the tray menu and is covered by the tray_accounts unit tests.
