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

run-email-campaign 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.

What it actually says

Run an email campaign

A campaign sends real email to many people and cannot be recalled. Treat every step as requiring confirmation.

1. Check capacity first

Call get_warmup_status. Sending above warm-up capacity on a young domain is the fastest route to throttling or a blocklist. If the audience exceeds the remaining daily capacity, say so and offer to split the send across days.

Call get_deliverability_score too — sending a large campaign from an account already scoring poorly compounds the damage.

2. Build it

  • list_templates / render_template to reuse existing design, or supply inline html.
  • create_campaign creates a draft. It never sends.
  • Confirm the audience with get_campaign and report the recipient count back to the user in plain numbers before going further.

3. Send

  • send_campaign sends immediately.
  • send_campaign with scheduled_at schedules it.

Get explicit confirmation of the recipient count and the subject line first.

4. Report

After sending, get_analytics with the campaign id. Useful reference points: open 20–25%, click 2–5%, bounce under 2%, complaints under 0.1%. Flag anything outside those ranges rather than reporting the number without context.

Testing

Suggest an A/B test on the subject line when the audience is large enough — see the ab-test-campaign skill. Below roughly 1,000 recipients per variant a test will not produce a trustworthy winner; say so instead of running one.

Changes

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.
