## The prompt

```text
Validate my [feed name] feed and list every required field that is missing, or mapped with no source value. Then look at the current field mapping and the WooCommerce product fields I can map from, and suggest a source for each problem field, for example GTIN from a custom field or brand as a fixed value. Show me the proposed mapping as a table and wait for my OK. After I approve, save the mapping and keep all my existing mappings. Then validate again and regenerate the feed.
```

## What happens when you paste it

You: Validate my [feed name] feed and list every required field that is missing, or mapped with no source value…

Assistant: Feed "Google Shopping US" is missing 2 required fields: Brand (g:brand) and GTIN (g:gtin). Condition (g:condition) is mapped but has no source value. Calling: `adtribes/get-feed-validation`, `adtribes/get-feed`, `adtribes/list-feed-attributes`, `adtribes/set-field-mapping`, `adtribes/regenerate-feed`.

Assistant: This will make changes in WooCommerce. Do you want me to go ahead?

Assistant: Mapped g:brand to the fixed value "Acme Outdoor", g:gtin to your _gtin custom field and g:condition to "new". Validation now shows 0 errors. Regeneration is scheduled.

## Abilities this recipe calls

- **Validate feed** (`adtribes/get-feed-validation`, read only, from AdTribes): Checks a feed against its channel and lists missing required fields and other issues.
- **Get feed settings** (`adtribes/get-feed`, read only, from AdTribes): Shows the full setup of one feed: mappings, filters, rules and tracking settings.
- **List mappable product fields** (`adtribes/list-feed-attributes`, read only, from AdTribes): Lists the WooCommerce product fields you can map into a feed.
- **Set feed field mapping** (`adtribes/set-field-mapping`, asks first, from AdTribes): Sets which product field fills each channel field in a feed.
- **Regenerate feed** (`adtribes/regenerate-feed`, asks first, from AdTribes): Rebuilds a feed file now, in the background by default.

## Variations

Add one of these to the end of the prompt. Swap anything in [brackets] for your own details.

- Do this for every feed that fails validation, one feed at a time.
- Fix the mapping only, and do not regenerate the feed yet.
