When to use it

Use it when

  • CPA jumped beyond noise on meaningful spend.

Do not use it when

  • No specific contraindication beyond the preconditions below.

What it needs first

Required

Preconditions

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

Inputs

window
Analysis window.Default: last 30 days.

Procedure

In order. Every tool named is one the gateway ships, and links to its reference.

  1. Split spend vs conversions.

  2. Check event volumes on the pixels.

  3. Run fatigue diagnostics on the spending creative.

Decision rules

The observable condition, what it lets you conclude, and what takes the conclusion back.

  • When

    The platform's fatigue tool flags the top spenders

    Conclude

    Creative cause with the platform's own evidence: refresh list, ranked by spend.

Evidence every conclusion must carry

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

Where the agent stops

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

How it goes wrong quietly

The cases where the analysis is wrong and still looks right. Read them before trusting a number.

  • TikTok auction seasonality is sharp around cultural moments: a spike can be the calendar, check the market before the account.
