# MK-400 | Add-Friend Flow Friction Check

For ordinary chat, upload `packs/mk-400.md`, which includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Friction in claiming benefits and taking the next step**

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: Actual joining/redemption steps, links or screens, each step’s tested state/errors, next destination, incentive conditions and available funnel data

## Method steps

1. Check whether joining offers immediate access to the incentive with little friction; avoid unnecessary steps that cause abandonment
2. Check whether the incentive relates to the user's current context / pain point and whether the next step is clear after joining
3. Do not treat low CPF as proof of a successful flow; also examine post-join interactions, first purchases, and repeat purchases

## Calculation and interpretation

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

## Required output fields

| 7 | Limitations | Original evidence, intermediate method results, or an explicit unknown; do not fabricate |

## Verification cases

**MK-400-A1 | Drop-off report exists, redemption steps unavailable**

Expected: List step/screen checks without claiming a broken button
