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

email-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 8d 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.

Email triage classification skill.

When to activate

Use this skill when processing a new email that needs to be classified for priority and action required.

Categories

Category Action Slack alert
URGENT Needs immediate attention Individual, immediate
REPLY_NEEDED Requires a response Individual
FYI Informational, no action Batch digest (3+)
NEWSLETTER Subscription content Batch digest (3+)
NOTIFICATION Automated system notice Batch digest (3+)
SPAM Unwanted, unsolicited Never

Methodology

1. Read the email

Read the full message with read_email. Note:

  • Subject line
  • Sender (From header)
  • Recipients (To/Cc -- are you the sole recipient or on a list?)
  • Date
  • Body content (first 500 chars are most informative)
  • Thread indicators (Re:, In-Reply-To header)

2. Check sender profile

Recall the sender from semantic memory:

recall("<sender email> sender_profile")

If a profile exists, use it to inform classification:

  • Known high-priority senders shift toward URGENT/REPLY_NEEDED
  • Known newsletter senders shortcut to NEWSLETTER
  • Known notification senders shortcut to NOTIFICATION

If no profile exists, create one after classification:

remember("<name>, <email>, first seen <date>, context: <topic>",
         category="sender_profile")

3. Content analysis

Scan the email body for signal indicators:

URGENT signals:

  • Words: urgent, asap, immediately, critical, emergency, deadline, time-sensitive, action required, escalation
  • Patterns: short deadline mentions ("by end of day", "within 1 hour")
  • Direct address to you with a demand
  • High-priority headers (X-Priority: 1)

REPLY_NEEDED signals:

  • Direct questions (sentences ending with ?)
  • Requests: "can you", "could you", "please", "would you mind"
  • Meeting invitations or scheduling requests
  • Approval requests
  • You are the sole recipient (To, not Cc)

FYI signals:

  • Informational tone, no questions or requests
  • You are on Cc, not To
  • Status updates, announcements
  • Shared documents or links for reference

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.
