Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

inbox-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Inbox Review

Systematic morning inbox review with email-specific intelligence.

Multi-Account Handling

Always iterate ALL configured accounts, not just the default:

# List folders for all accounts first
folders(action="list")

# 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
