# MK-029 | Identifying role-marker products

For a regular chat, upload `packs/mk-029.md`. It includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Products that may provide identity clues and their limitations**

Hypotheses are useful but do not establish demographics or market share; do not fabricate interview content or customer experiences

## Required inputs

Provide: Product facts, existing customer data, surveys, or customer-service records

## Method

1. Look for role-marker products from three angles: functional markers, consumption markers, and contextual markers
2. Functional markers provide role clues, while gifts, proxy purchases, and use by someone else still need checking. Consumption markers use continued usage frequency to observe habits; contextual markers provide clues about a particular life situation
3. A role-marker product need not be a bestseller; the point is whether its purchase helps the brand determine more confidently "who this person is"

## Calculations and interpretation

Treat customer roles and motivations as hypotheses initially; do not establish someone's actual identity from a single purchase behavior

## Required output fields

| Order | Field | How to complete |
|---:|---|---|
| 1 | Hypothesized group | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 2 | Buying/using role | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 3 | Trigger situation | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 4 | Tasks and concerns | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 5 | Supporting clues | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 6 | Counterexamples | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 7 | Items to validate | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |
| 8 | Suitable message | Use source evidence, an intermediate method result, or an explicit unknown; do not invent information |

## Verification cases

**MK-029-C05 | An order contains maternity and baby products**

Expected: Do not immediately identify the buyer as a mother; separate the buying and using roles

**MK-029-C06 | Different clues support two situations**

Expected: Keep both candidates and request the data that would distinguish them
