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-triage 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Inbox Triage

Turn a full inbox into three stacks: handled, drafts-for-your-review, and flagged-for-a-decision. Don't send anything without explicit approval.

Before starting

  1. Read context/about-me.md — who is the user, who are their priority contacts
  2. Read context/voice.md — any draft reply must sound like them
  3. Read context/preferences.md — their rules on what to auto-reply vs. escalate
  4. Read memory.md if it exists — prior corrections to triage logic

What to produce

A markdown file saved to /output/inbox-triage-{YYYY-MM-DD-HHmm}.md with four sections:

  1. Archived / filed (no action needed) — count + one-line summary. The newsletters, receipts, notifications, FYI-cc'd threads. Just counts, not individual items.
  2. Drafted replies for your review — threads where a standard response is appropriate and you've drafted it. Each item: sender, subject, one-line context, draft reply.
  3. Flagged for your decision — threads that need the user's judgment before anyone replies. Each item: sender, subject, one-line context, the specific decision needed.
  4. Summary — total emails processed, how many in each bucket, any patterns worth noting.

Do not actually send, archive, or label anything unless the user has explicitly approved auto-actions in their preferences file.

Inputs

  • Gmail or equivalent connector (required)
  • The window to triage (default: since last triage run, or last 12 hours)
  • Priority contacts list from about-me.md or preferences.md

How it works

  1. Pull emails from the window (unread + recently-read)
  2. For each email, categorize:
    • Archive-worthy? Newsletters, receipts, automated notifications, CC threads where user isn't the primary recipient, confirmations that don't require action
    • Draftable? Clear request with an obvious standard answer — meeting confirmations, simple scheduling, "thanks" replies, known-answer FAQs
    • Needs decision? Everything else that isn't obvious
  3. For draftable items, write a reply in the user's voice. Under 80 words unless the situation needs more.
  4. For decision items, name the specific decision needed ("accept/decline," "yes/no/renegotiate," etc.)
  5. Save the triage file, tell the user what to look at first

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.
