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-summary 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 10d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use get_emails_with_preview to fetch recent emails with body previews in one pass. Default to limit: 50. Each email in the response now includes priority (1–5) and category fields — use these directly rather than re-classifying manually.

Pre-Summary: Check Reminders

Before presenting the digest, call list_reminders. If any reminders are overdue or due today, surface them first:

⏰ **Follow-up reminders due**
- UID 123 (INBOX) — [note] · overdue
- UID 88 (INBOX) — [note] · due today

Skip this block if list_reminders returns no active reminders.

Categories

Map the category field from the tool response to digest sections:

Tool category Digest section
ActionRequired 🔴 Action Required
Finance 💰 Finance & Billing
Travel or Calendar 📅 Events & Calendar
Newsletter, Social, Updates 📦 Updates & FYI

Use the priority field to sort within sections — highest priority first. Emails with priority ≥ 4 always appear in Action Required regardless of category.

If your local rules (from list_rules) add overrides, apply them: a rule with action_type: "priority" bumps the score; action_type: "category" overrides the section; action_type: "flag" adds a tag next to the sender name.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
