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 | $0.00104 | $0.02653 |
| Opus 5 | $0.00052 | $0.01326 |
| Sonnet 5 | $0.00021 | $0.00531 |
| Haiku 4.5 | $0.00010 | $0.00265 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 269 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mailchimp Skill
Manage Mailchimp email campaigns, audiences, templates, and reports via the Mailchimp Marketing API v3.
Authentication
Set MAILCHIMP_API_KEY in your environment or .env file. The API key format is {key}-{dc} where dc is the datacenter (e.g., us7). The scripts auto-extract the datacenter to build the correct base URL.
export MAILCHIMP_API_KEY="your-api-key-us7"
Important: Template Types & Content Population
Mailchimp has two editor types with very different API support:
| Feature | Classic/Legacy (content_type: "template") |
New Editor (content_type: "multichannel") |
|---|---|---|
| Editable regions | mc:edit="section_name" attributes |
data-block-id attributes |
| API content population | Full support via template.sections |
NOT supported |
| Template creation via API | POST /templates |
Not available |
| Default content discovery | GET /templates/{id}/default-content |
Returns empty |
For programmatic content control, always use classic/legacy templates with mc:edit regions. The Mailchimp API v3 has no endpoints for editing multichannel (new editor) content blocks.
How Template Sections Work
-
Build an HTML email template with
mc:editattributes on editable elements:<td mc:edit="header_title"><h1>Default Title</h1></td> <td mc:edit="hero_image"><img src="placeholder.jpg"/></td> <td mc:edit="body_text"><p>Default body content</p></td> -
Upload the template via
POST /templates(creates a classic template) -
Discover available sections:
python scripts/templates.py content --template-id 12345 # Returns { "sections": { "header_title": "...", "hero_image": "...", ... } } -
Create a campaign and populate all sections in one call:
python scripts/campaign_content.py set --campaign-id abc123 \ --template-id 12345 --sections '{"header_title": "<h1>April News</h1>", "hero_image": "<img src=\"https://example.com/photo.jpg\"/>"}'
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 Buzzmatic/awesome-agent-skills (1 stars, last pushed 2mo ago), licensed MIT. It adds 104 tokens to every session and 2,653 once invoked, about $0.0005 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 2026-08-31.
