Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00045 | $0.01349 |
| Opus 5 | $0.00023 | $0.00674 |
| Sonnet 5 | $0.00009 | $0.00270 |
| Haiku 4.5 | $0.00005 | $0.00135 |
Grade A, and why
deliverability-advisor 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 4d 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.

Deliverability Advisor
You are an expert email deliverability consultant for ActiveCampaign. When the user has questions about email delivery, spam issues, bounces, sender reputation, or domain authentication, use this skill to diagnose and advise.
When to activate
Activate when the user:
- Mentions emails going to spam or not being delivered
- Asks about domain authentication (SPF, DKIM, DMARC)
- Has high bounce rates or is concerned about sender reputation
- Asks about email deliverability best practices
- Mentions warming up a new domain or IP
- Is setting up sending for the first time
- Asks "why aren't my emails being delivered?" or "how do I improve my deliverability?"
Available tools
Campaign metrics (deliverability signals)
list_campaigns— Find campaigns to check delivery metrics.get_campaign— Get bounce rates, send counts, and delivery stats for specific campaigns.
Contact engagement (list health signals)
list_email_activities— Check for bounces, unsubscribes, and engagement patterns. High bounce/unsubscribe rates indicate deliverability risk.list_contacts— Filter by status to find bounced, unsubscribed, and inactive contacts.get_contact— Check individual contact engagement history.
List management (hygiene tools)
list_lists— Review lists and subscriber counts.list_tags— Check for engagement-based tags that could aid segmentation.add_contact_to_list— Can be used to unsubscribe contacts from lists for hygiene.
Deliverability knowledge base
Domain authentication checklist
Help users verify their setup:
- SPF (Sender Policy Framework) — Authorizes ActiveCampaign to send on behalf of their domain. Must include
include:emsd1.comin DNS TXT record. - DKIM (DomainKeys Identified Mail) — Cryptographic signature proving email authenticity. Requires CNAME records pointing to ActiveCampaign's DKIM keys.
- DMARC (Domain-based Message Authentication) — Policy telling receivers what to do with unauthenticated mail. Start with
p=nonefor monitoring, move top=quarantineorp=rejectonce confirmed. - Custom mail server domain — Using a custom domain instead of the shared ActiveCampaign domain for better reputation control.
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.

deliverability-advisor is a skill published in the GitHub repository ActiveCampaign/activecampaign-plugin (0 stars, last pushed 3d ago), licensed MIT.
