Inbox Review

Systematic morning inbox review with email-specific intelligence.

Multi-Account Handling

Always iterate ALL configured accounts, not just the default:

# List accounts first
messages(action="list_accounts")

# Then search each account
messages(action="search", query="UNSEEN", account="[email protected]")
messages(action="search", query="UNSEEN", account="[email protected]")

Never assume a single account. Users with EMAIL_CREDENTIALS containing multiple accounts expect all to be checked.

IMAP Search Syntax

Use proper IMAP search criteria -- these are NOT free-text queries:

Intent	Correct syntax	Wrong (will fail or return wrong results)
Unread emails	UNSEEN	unread, is:unread
Since a date	SINCE 2026-03-20	after:2026-03-20, date>2026-03-20
From a sender	FROM [email protected]	from:sender, [email protected]
Flagged/starred	FLAGGED	starred, is:starred
With subject	SUBJECT "meeting notes"	subject:meeting
Combine criteria	UNSEEN SINCE 2026-03-20	UNSEEN AND SINCE 2026-03-20 (no AND keyword)
Unread + from	UNSEEN FROM [email protected]	UNSEEN AND FROM [email protected]

IMAP criteria are space-separated (implicit AND). There is no explicit AND/OR keyword in basic IMAP search.

Thread Grouping

Group messages by conversation, not individual emails:

1. Fetch unread messages
2. Group by Subject line (strip Re:, Fwd: prefixes, normalize whitespace)
3. Within each thread, sort by date ascending
4. Display thread with message count: "Meeting Q2 Planning (4 messages, latest from Alice 2h ago)"

This prevents showing 10 individual replies to the same thread as 10 separate items.

Priority Classification

Classify based on recipient role and sender signals:

Signal	Priority	Reasoning
You are in To: field	Action Required	Direct request to you
You are in CC: field	FYI	Informational, no action expected
Mailing list headers present	Low	Bulk/automated
Reply-To differs from From	Low	Likely automated/newsletter
Known sender + To: you directly	High	Personal direct message
noreply@, notifications@	Low	System notification

Output Format

Present results grouped by priority, not by account:

## Action Required (3)
- [work] "Q2 Budget Approval" from CFO (2h ago) -- needs your sign-off
- [work] "Code Review: PR #142" from Alice (5h ago) -- review requested
- [personal] "Lease Renewal" from landlord (1d ago) -- response needed

## FYI (5)
- [work] "Sprint Retro Notes" from PM (3h ago) -- CC'd, meeting summary
...

## Low Priority (12)
- [work] 8 newsletter/notification emails
- [personal] 4 promotional emails

For Action Required items, suggest one-line draft replies the user can approve or edit.

When to Use

• Start of day inbox review
• Catching up after time away from email
