# Diagnose a Pinterest spend drop fast

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

The Pinterest spend-drop sequence: entities and budgets first, delivery metrics for confirmation.

**Intent.** Why Pinterest spend fell: statuses, budgets, or delivery.

## When to use

- Pinterest spend fell hard against its norm.

## When not to use

- No specific contraindication beyond the preconditions below.

## Sources

Required: Pinterest Ads

## Preconditions

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

## Inputs

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

## Procedure

1. Confirm the drop. — tools: `pinterest_run_report`
2. Check entity statuses including archived. — tools: `pinterest_get_account_entities`
3. Read delivery metrics for the affected scope. — tools: `pinterest_get_delivery_metrics`

## Decision rules

- **When** Entities were archived or paused near the date → **conclude** Human or rule cause: attribute and date; Pinterest keeps no exposed change log, so the entity state is the evidence.

## 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

- No change log exists here: absence of evidence for edits is weaker than on Google, say so in the conclusion.

## Output

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