# Check the Meta catalogue behind dynamic ads

> Tier: recipe. Operating recipe: real tool sequence, core rules, known traps.

Catalogue products read for availability, price sanity and coverage, before dynamic performance is judged.

**Intent.** Whether the catalogue serves what the ads assume.

## When to use

- Weekly on catalogue-driven accounts.
- After feed pushes.

## When not to use

- No specific contraindication beyond the preconditions below.

## Sources

Required: Meta Ads

## Preconditions

- The account is ticked in the dashboard, confirmed via list_accounts.

## Inputs

- `window`: Analysis window. Default: last 30 days.

## Procedure

1. Pull catalogue products with statuses. — tools: `meta_get_catalog_products`
2. Cross top sellers against what actually serves. — tools: `meta_join_product_insights`

## Decision rules

- **When** Top sellers are missing or rejected in the catalogue → **conclude** Feed fix outranks any campaign change: route to shopping-feed-health.

## Evidence requirements

- Every figure carries its account, metric and window.
- Anything below a readable sample size is reported as unjudged, not as zero.

## Human approval boundary

- The readout changes nothing. Any change it motivates goes through Safe Writes: preview, human confirmation, then apply.

## Failure modes

- Catalogue counts differ from feed counts during processing windows: date the read.

## Output

- **Readout**: The figures, with windows and accounts named.
- **Flags**: What deserves a deeper skill or a human decision.
