Evaluator guide

Sign in at command-inbox.sayantanbal.in with any Google account once OAuth is published to Production. If the app is still in Testing mode, request access via Judge access.
Use a desktop browser first (Chrome or Edge). Mobile works — open the menu (☰) for Sent, Snoozed, and Archive.
Fast path: on the first onboarding screen (“When do you work?”), click Skip to inbox to use default 9–5 weekdays and jump straight to triage.
Prefer a fully indexed inbox for semantic search (/) — fresh accounts still get the last 50 threads classified immediately.

Architecture (Corsair spine)

Gmail push → Pub/Sub → /api/webhooks → Corsair processWebhook → AI lanes + Pusher
Calendar push → /api/webhooks/calendar with channel-token verification
Reads/writes → tenant.gmail.api.* / tenant.googlecalendar.api.* (Corsair-issued tokens)
google-proxy — watches, attachments, attendee freeBusy where the SDK has no surface (still Corsair tokens, not raw OAuth in app code)
Agent — MCP list_operations / get_schema for discovery; typed tools with approval for sends and invites (run_script intentionally disabled)
Cursor — same tools via bun mcp-server.ts in the repo root

Open Inbox → note Reply / Schedule / FYI lane tabs.
Press j / k to move between threads.
Press e to archive — watch the undo toast (5 seconds).
Press / for semantic search over indexed mail (not entire mailbox history until background index completes).

This is the headline feature:

Switch to the Schedule lane (or pick a scheduling thread).
Press M — inline availability appears beside the thread.
Pick a slot (busy attendee slots are grayed when Calendar free/busy is available).
Review the confirmation draft in the composer → send.
Optional: open Calendar tab (~3s) to see the new Meet event.

Press ⌘K (or tap the floating command button on mobile).
Type sent, snooze, or a sender name to jump.
Open a shareable URL: /inbox?thread=THREAD_ID&lane=schedule — the thread opens directly.

Open the Agent tab (mobile) or right panel (desktop).
Try: "Send a calendar invite to friend@corsair.dev at 9 AM next Thursday and email them to confirm." (import demo contacts in onboarding if needed)
Approve send_email and create_calendar_invite when prompted — nothing sends without your click.

Signal	Where
Corsair SDK reads/writes Gmail + Calendar	Archive, send, `M` flow, agent tools
Typed MCP tools + approval gates	Agent chat — no silent sends
AI triage quality	Lane tabs after connect (banner if AI keys missing)
Keyboard density	`j/k/e/r/m/s`, G-chords, `⌘K` palette
Production polish	Undo, realtime lane updates, mobile drawer

Screenshots and hero GIF paths (drop files before final submission):

See public/demo/README.md in the repo for the recording checklist.

Issue	Fix
"Access blocked" on Google sign-in	OAuth not published, or email not in test users
Empty semantic search	Wait for indexing banner to clear, or use advanced search (`Mod+Shift+F`)
Dumb lanes / orange banner	Add OpenAI or Gemini key in Settings → AI
Agent won't send	Approve the tool card; check AI keys in Settings
Agent rate limited	Wait a minute — don't spam agent chat (in-memory limiter on serverless)
Calendar webhooks 503	Team must set HTTPS `APP_URL` and renew watches
