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 5.1 | $0.00025 | $0.00987 |
| Opus 5 | $0.00013 | $0.00494 |
| Sonnet 5 | $0.00005 | $0.00197 |
| Haiku 4.5 | $0.00003 | $0.00099 |
Grade A, and why
mailchimp 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 6d 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.

Creating Campaigns
Use mailchimp-create-campaign with:
type—regular,plaintext,absplit, orrssrecipients—{ "list_id": "..." }(required audience)settings—subject_line,from_name,reply_to,title
{
"type": "regular",
"recipients": { "list_id": "abc123" },
"settings": {
"subject_line": "Weekly Newsletter",
"from_name": "Acme Team",
"reply_to": "[email protected]"
}
}
Sending Campaigns
Use mailchimp-send-campaign with campaign_id. Ensure campaign has content and recipients before sending.
Pre-send checklist:
- Campaign has content (template or HTML)
- Recipients/audience set
- Subject line and from address configured
- Test email sent
Campaign Stats
Use mailchimp-get-campaign to retrieve delivery stats: emails_sent, opens, clicks, bounces, unsubscribes.
Audiences (Lists)
Adding Members
Use mailchimp-add-member with:
list_id(required) — the audience IDemail_address(required) — subscriber emailstatus—subscribed,unsubscribed,cleaned,pendingmerge_fields—{ "FNAME": "Alice", "LNAME": "Smith" }
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.

mailchimp is a skill published in the GitHub repository tallclub/matimo (11 stars, last pushed 3d ago), licensed MIT. It adds 25 tokens to every session and 987 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
