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

build-email-automation 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 11d 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

Build an email automation

1. Check what already exists

list_automations first. Two automations on the same trigger will both fire, and the contact receives duplicate mail — a failure users usually discover from a complaint rather than from the dashboard.

2. Design before building

Choose a trigger: contact_created, tag_added, campaign_opened, link_clicked, or date_based. Then lay out the steps with explicit delays and explain each choice to the user.

Practical guidance worth stating:

  • First email within an hour of the trigger; the rest spaced 2–4 days.
  • Keep a welcome series to 3–5 emails. Longer sequences bleed unsubscribes.
  • Include an exit condition (a tag applied on conversion) so a converted contact stops receiving the sequence.

3. Build it inactive

create_automation with active: false. Show the result via get_automation and let the user read the steps back before anything can fire.

Only call toggle_automation with active: true after explicit confirmation. Activating starts enrolling live contacts immediately.

Templates

list_templates and create_template — use {{variable}} placeholders and preview substitution with render_template before wiring a template into a step. An automation that ships Hi {{first_name}} to contacts with no first name is a visible, embarrassing failure.

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.
