# MK-399 | Add-Friend Incentive Design

For ordinary chat, upload `packs/mk-399.md`, which includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Immediate, relevant, low-friction reasons to connect**

Do not send messages or create automation without approval; if a tool cannot show recipient eligibility, do not assume everyone can be messaged

## Required inputs

Provide: friend or subscriber status, permissions, product content, campaigns, and channel reports

## Method steps

1. The incentive to add the account should answer “What do I get immediately by joining now?” rather than merely saying welcome / latest updates
2. Three conditions: immediate benefit, high relevance, and a low action threshold
3. Incentives can be monetary, content-based, or service-based, and need not be coupons; they must connect to the next step in the purchase path

## Calculation and interpretation

Verify contact consent, unsubscribes, and message specifications; friend counts and open rates are not sales

## Required output fields

| Order | Field | How to fill it in |

| 2 | Audience | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 3 | Plan / task | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 4 | Evidence and assumptions | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 5 | Prerequisites | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 6 | Resources | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 7 | Deliverables and acceptance | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |
| 8 | Unresolved items | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |

## Verification cases

**MK-399-A1 | Joining incentive exists but no next step**

Expected: Identify purpose/flow gap rather than enlarge the gift
