Getting it into your agent

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 | $0.00087 | $0.00789 |
| Opus 5.5 | $0.00035 | $0.00316 |
| Sonnet 5.5 | $0.00017 | $0.00158 |
| Haiku 4.5 | $0.00009 | $0.00079 |
Grade A, and why
email-sequence scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Email Sequence
Design email drip sequences and automation flows for "$ARGUMENTS". Plan trigger-based campaigns that nurture leads through the funnel.
Arguments. $ARGUMENTS may contain the project name and optional flags. Take the first token as <project> and treat --skip-checks as a flag; never include flags in file paths. All paths below use <project>. If --skip-checks is present, skip the prerequisite check and, before writing any artifact, append one line to .metapowers/marketing/<project>/skip-log.md: - <ISO timestamp> — <skill name> skipped prerequisite check for <artifact file> — reason: <reason or "none given">.
Prerequisites
Read .metapowers/marketing/<project>/00-strategy.md. If this file does not exist, tell the user:
Phase 0 (Strategy) has not been completed for "". Run
/marketing:customer-research <project>first, or use--skip-checksto bypass.
Process
-
Read context:
- Read
.metapowers/marketing/<project>/00-strategy.mdfor audience and messaging - Read
.metapowers/marketing/<project>/02-act.mdif it exists (for lead magnet and copy context) - Read
${CLAUDE_PLUGIN_ROOT}/shared/campaign-plan-template.mdfor structure
- Read
-
Define sequence type:
- Welcome/onboarding sequence
- Lead nurture sequence (post lead-magnet)
- Trial-to-paid conversion sequence
- Win-back for churned or lapsed customers — hand off to
/marketing:churn-prevention; this skill covers the other sequence types. - Post-purchase/retention sequence
- Which type(s) are most needed for ""?
-
Design the sequence:
- Number of emails and timing (days between)
- For each email: subject line, preview text, goal, key message, CTA
- Trigger and entry conditions
- Exit conditions (converted, unsubscribed, engaged)
- Branch logic (if applicable): what happens based on engagement?
-
Write email copy:
- Draft subject line variants for each email (2-3 per email)
- Write full email body copy for each email
- Apply messaging framework from strategy
- Include personalization variables
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.

email-sequence is a skill published in the GitHub repository bromso/metapowers (2 stars, last pushed 3d ago), licensed MIT. It adds 87 tokens to every session and 789 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-21.
