Token cost

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.

Security

Grade A, and why

email-retention-sequences 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 11d 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.

email-retention-sequences

Purpose

Generate a retention email sequence (5-7 emails) for existing customers that reduces churn and increases lifetime value. Unlike upsell sequences, retention emails are NOT about selling the next thing — they're about making the current purchase successful. The sequence reinforces the buying decision, delivers usage value, builds relationship, surfaces wins, and prevents cancellation before it starts. RMBC principles apply differently here: Research drives personalization, Mechanism explains how to get results, Brief structures the nurture arc, Copy executes with warmth over urgency.

Inputs

Input Required Description
product_name Yes The product the customer owns — name and core promise
target_audience Yes Who the customer is — demographics, goals, experience level
key_benefits Yes Top 3-5 benefits the product delivers when used correctly
subscription_model Yes One of: one-time (prevent refunds, encourage repeat purchase) or subscription (prevent cancellation)
sequence_length No Number of emails: 5, 6, or 7 (default: 7)
churn_triggers No Known reasons customers leave — objections, confusion points, competitor pull
send_timing No Days between emails (default: Day 1, 3, 7, 14, 21, 30, 45)

Execution Protocol

Step 1 — Load Framework Context

Read rmbc-context/SKILL.md to load RMBC framework definitions. Retention sequences invert the typical RMBC sales arc — instead of moving toward a purchase, they reinforce an existing one. Mechanism explains HOW to get results, not WHY to buy.

Step 2 — Map the Retention Arc

Email Role Emotional Need Focus
1 — Welcome/Onboard Set expectations, quick win Excited but unsure Show them step 1 — reduce overwhelm
2 — Quick Win Deliver the fastest visible result Needs early proof it works One specific action → one specific result
3 — Deeper Value Teach an advanced use case or hidden feature Curious, engaged Mechanism: HOW the product works behind the scenes
4 — Social Proof Show other customers' wins Needs validation Stories of people like them succeeding
5 — Objection Preempt Address the #1 reason people quit Doubt creeping in Name the objection, resolve it directly
6 — Milestone Check Celebrate progress, survey for feedback Wants acknowledgment "You've been with us X days — here's what you've achieved"
7 — Renewal/Advocacy Reinforce commitment, invite community or referral Loyal, ready to advocate Subscription: renewal framing. One-time: referral or repeat
