# MK-253｜Product Description Completeness Check

For a regular chat, upload `packs/mk-253.md`; it includes the shared rules, this method, and required references

## Purpose

This Skill delivers: **Missing information about features, uses, and limitations**

When IDs cannot be matched one-to-one, leave them unmatched rather than guess; do not invent a match rate without complete event samples

## Required Inputs

Catalog platform, original description by SKU or variant, product pages and authoritative function, use, and limitation data, plus relevant current field specifications

## Method Steps

1. Match each SKU or variant to the actual product and retain the original description and source
2. Check function, use context, and applicable limitations separately, marking covered, missing, incorrect, or unknown information; retain limitations even when they weaken promotional appeal
3. Deliver a usable revised description from verified facts, retaining conditions and variant differences without adding unsupported effects, promotions, or uses
4. Map original values, gaps, revised wording, and sources, then check current platform requirements without imposing an invented fixed length or ranking template

## Calculation and Interpretation

Use product data for specifications and prices; verify catalog fields and disapproval rules during production

## Required Output Fields

| Order | Field | How to complete |
|---:|---|---|
| 1 | SKU or variant and product source | Use the supplied source, calculation, or explicit unknown |
| 2 | Original description | Use the supplied source, calculation, or explicit unknown |
| 3 | Function, use, and limitation checks | Use the supplied source, calculation, or explicit unknown |
| 4 | Gaps or errors | Use the supplied source, calculation, or explicit unknown |
| 5 | Proposed description | Use the supplied source, calculation, or explicit unknown |
| 6 | Evidence and specification checks | Use the supplied source, calculation, or explicit unknown |
| 7 | Unconfirmed facts | Use the supplied source, calculation, or explicit unknown |

## Verification Cases

**MK-253-A1 | Official data limits the product to indoor use but the description omits this condition**

Expected: Add the indoor-use limitation while retaining actual functions; do not claim all-weather outdoor suitability
