## What happened

The Agents bar widget (`omarchy.agents`) misreports Claude's auth status when Claude Code is authenticated through Google Vertex AI (`ANTHROPIC_VERTEX_PROJECT_ID` set) instead of the standard `claude login` OAuth flow. The panel's hero card shows "Waiting for auth" with the help text "Run `claude auth login` to restore authoritative usage," even though Claude Code is actively running and working normally.

Separately, the widget also has no collector for the Gemini CLI at all, so Gemini never appears in the panel/switcher even when it's installed, authenticated, and in active use alongside Claude and Codex.

## Root cause (traced in source)

`/usr/share/omarchy/bin/omarchy-agent-usage-claude`'s `oauth_login()` only ever reads an access token from `~/.claude/.credentials.json` (`claudeAiOauth.accessToken`). When Claude Code is authenticated via Vertex (or presumably Bedrock), that file is never created — there's no OAuth login step — so `access_token` is always `""`, `collect_limits()` takes the early-return branch, and the record is written with `"usageStatusText": "Waiting for auth"` regardless of whether Claude Code is actually working.

The **local stats** (today's tokens, model breakdown, weekly chart) are unaffected because those come from scanning `~/.claude/projects/*.jsonl` transcripts directly (`hasLocalStats: true`), independent of the auth method. So the panel ends up in a confusing half-working state: usage numbers accrue correctly, but the hero card permanently shows an auth warning with an incorrect remedy ("run `claude auth login`" does nothing useful — there's no OAuth session to restore).

Separately, `/usr/share/omarchy/shell/plugins/agents/manifest.json` and `bin/` only define collectors for `claude`, `codex`, and `fireworks` — there is no `omarchy-agent-usage-gemini`. This appears to be a missing feature rather than a bug, but is filed alongside since it compounds the confusion (a user with two working CLIs, Claude and Gemini, only ever sees one in the widget, and the one they do see shows a false auth error).

## Expected behavior

- When `~/.claude/.credentials.json` is absent but Claude Code has recent local transcript activity (`hasLocalStats` / `totalPrompts > 0`) and/or `ANTHROPIC_VERTEX_PROJECT_ID` / `CLAUDE_CODE_USE_VERTEX` / `CLAUDE_CODE_USE_BEDROCK` env vars are set, the widget should not claim the user needs to run `claude auth login`. At minimum it should distinguish "OAuth session not applicable (non-OAuth auth backend, limits unavailable)" from "OAuth session lapsed, please re-auth."
- Gemini CLI usage should be collectible the same way `claude`/`codex` are, following the record contract described in the plugin's README (a `bin/omarchy-agent-usage-gemini` collector).

## Steps to reproduce

1. Authenticate Claude Code via Google Vertex AI (`ANTHROPIC_VERTEX_PROJECT_ID` set, no `claude login` OAuth session, so `~/.claude/.credentials.json` does not exist).
2. Use Claude Code normally — transcripts accrue under `~/.claude/projects`.
3. Open the Agents bar panel.
4. Observe: hero card shows "Waiting for auth" / "Run `claude auth login` to restore authoritative usage" even while Claude Code is being used in the same moment, and token counts are visibly incrementing.
5. Separately: have the Gemini CLI installed and authenticated/in use — it never appears as a subscription tab/switch entry in the panel, because no collector exists for it.

## System details

- Omarchy version: 4.0.0-1
- Kernel: Linux 7.1.8-arch1-3
- Hardware: HP OMEN Transcend Gaming Laptop 14-fb0xxx
- GPU: Intel Arc Graphics (Meteor Lake-P) + NVIDIA GeForce RTX 4070 Max-Q
- `omarchy debug` command not present in this version (`omarchy commands --all` has no `debug` entry), so no diagnostic log/URL is attached.
