# Inventory the Meta creative library in use

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

The creative and asset inventory behind active ads: formats, first-seen dates, where each asset serves.

**Intent.** What creative actually runs: formats, ages, reuse across campaigns.

## When to use

- Before a production sprint.
- Auditing creative diversity on an account.

## 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 creatives and their assets for active ads. — tools: `meta_get_creatives`, `meta_get_creative_assets`
2. Group by format and age; map reuse across campaigns.

## Decision rules

- **When** Most spend runs on assets older than the account's refresh cycle → **conclude** The pipeline, not the media buying, is the constraint: quantify spend on stale assets.

## 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

- Post IDs reused across ads make naive counts overstate variety.

## Output

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