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 | $0.00046 | $0.00460 |
| Opus 5.5 | $0.00018 | $0.00184 |
| Sonnet 5.5 | $0.00009 | $0.00092 |
| Haiku 4.5 | $0.00005 | $0.00046 |
Grade A, and why
hubspot-follow-email 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 25d 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
HubSpot follow / marketing email (DRAFT)
When to use
- Event invite or reminder in HubSpot Marketing Email
- Post-event follow-up to registrants / no-shows / attendees
- Nurture that references a real system or artifact (not vague AI hype)
Non-negotiables
- One primary CTA. Secondary link optional, not three competing buttons.
- Personalization tokens must exist in the HubSpot list/properties — do not invent tokens.
- No fabricated metrics, customer logos, or case studies.
- Draft in markdown first; paste into HubSpot only after human edit.
- Prefer creating a HubSpot draft (not send) unless explicitly asked to schedule/send.
Inputs
| Input | Required |
|---|---|
| Goal (invite / reminder / post-event / nurture) | yes |
| Audience list or segment definition | yes |
| Offer / CTA URL | yes |
| Brand voice / prior email to match | no |
| Proof points (only if verified) | no |
Flow
- Classify the email: invite | reminder | day-of | post-attend | post-no-show | nurture.
- Pick template from
templates/matching the class. - Fill placeholders; strip unused optional blocks.
- Lint against
references/anti-slop.md. - Deliver as HubSpot draft (or markdown in Drive) — do not send unasked.
- QA: subject ≤50 chars preferred; preview text set; mobile-safe short paragraphs; unsubscribe footer present.
Output
- Subject + preview text
- Body (markdown)
- Suggested HubSpot properties / personalization tokens used
- Send-time suggestion (timezone aware) — suggestion only

What ships with it
6 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.
