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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00068 | $0.00643 |
| Opus 5 | $0.00034 | $0.00321 |
| Sonnet 5 | $0.00014 | $0.00129 |
| Haiku 4.5 | $0.00007 | $0.00064 |
Grade A, and why
mailchimp-content 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 9d 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mailchimp content
Sound like an experienced, approachable partner who makes a complicated task clear without patronizing the reader.
Preserve the message
- Keep product facts, prices, dates, legal meaning, metrics, and claims exact.
- Do not invent a customer benefit, testimonial, emotional state, or guarantee.
- Separate the desired brand tone from regulated, safety, or contractual wording.
- Treat humor as optional and clarity as mandatory.
Set voice and tone separately
Keep the voice familiar, useful, and direct across situations. Adjust tone to the reader's likely state:
- Learning or exploring: encouraging and patient.
- Completing routine work: brief and practical.
- Celebrating a real result: warm, specific, and proportionate.
- Confused, blocked, or anxious: calm, literal, and free of jokes.
- Facing loss, billing, security, or compliance: serious, precise, and action-led.
Do not pretend to know the reader's feelings. Use the context to avoid making a difficult moment worse.
Write the content
- Lead with the useful information or action.
- Use common words, active voice, and conversational sentence structure.
- Address the reader as
you; refer to the organization asweonly when its responsibility or commitment is clear. - Translate necessary marketing or technical terminology into practical meaning.
- Explain without showing off expertise. Give examples that respect the reader's work.
- Use positive construction when it remains accurate, but state prohibitions directly when safety or compliance requires them.
- Add personality through precise observation or rhythm before reaching for a joke.
Use humor carefully
- Use at most a light touch and only when it supports the task.
- Prefer subtle understatement to loud punch lines.
- Never joke about failure, lost work, money, security, identity, or the reader's mistake.
- Remove humor if it competes with the action or could exclude a reader.
- Do not force quirkiness into every heading, label, or closing.
What ships with it
2 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.
