# Inventory TikTok audiences and usage

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

Custom and lookalike audiences mapped to usage, before consolidation or new builds.

**Intent.** The audience estate with sizes and the ad groups using each.

## When to use

- Quarterly hygiene.
- Before overlap analysis.

## 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. List audiences with types and sizes. — tools: `tiktok_get_audiences`
2. Read details for the ones in use and map ad groups. — tools: `tiktok_get_audience_details`, `tiktok_get_adgroups`

## Decision rules

- **When** Audiences built from stale sources still serve prospecting → **conclude** Date the source and flag the ad groups: stale seeds make stale lookalikes.

## 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

- Size estimates are bands: differences inside a band are not findings.

## Output

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