# Check TikTok Shop catalogue health

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

Shop catalogue diagnostics: rejects, coverage, the commerce leg of feed health.

**Intent.** Whether the shop catalogue serves what commerce campaigns assume.

## When to use

- TikTok Shop campaigns live.
- After feed pushes.

## When not to use

- No specific contraindication beyond the preconditions below.

## Sources

Required: TikTok Ads

## Preconditions

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

## Inputs

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

## Procedure

1. Run shop catalogue diagnostics. — tools: `tiktok_get_shop_catalog_diagnostics`
2. Rank fixes by affected sellers or GMV where readable.

## Decision rules

- **When** Rejects concentrate on one attribute → **conclude** One upstream fix: name the attribute and count.

## 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

- Shop and ads catalogues can diverge: name which one the diagnostic read.

## Output

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