Ad variant change auditor

What it does

Audit the differences in actual control/variant drafts against a predeclared experiment question. This checks implementation of the test contract; it does not generate variants, plan a test from scratch or infer causal results. Checks actual variation against an already specified experiment and returns a confound/repair matrix; not creative generation, outcome analysis or blind prompt scoring.

What goes in and out

You give it

• Your test question and the one thing you want to change
• Your control ad text and version
• Your variant ad texts and versions
• Images or video for each ad (optional)
• Audience, placement and landing page for each ad (optional)
• Your image ads (optional)
• A plan (optional)
• Audit report (optional)

You get

• A list of every change between the control and each variant
• A label on each change: planned, unplanned or could not check
• A ready or not-ready verdict for each variant
• The smallest fix for each problem, such as undoing a change or splitting it into its own test
• A list of what is still unknown

How the task works

• Define the review. Read the supplied test question, control ID/version, intended changed variable, invariants, audience/placement, destination and observation plan. If no comparison contract exists, list the missing decisions rather than inventing a post-hoc hypothesis.
• Compare the actual records. Distinguish a superficial wording change from a change in meaning. Two synonyms can preserve a factor; a different proof, price, implied promise or action may change the buying proposition even when only one sentence was edited.
• Return a bounded handoff. Return a variant-readiness matrix, repair list and remaining unknowns. Bind it to asset versions; a later change to proof, price, audience, destination or creative requires rechecking the affected comparison.

Full instructions

• Open Claude, ChatGPT or Gemini and paste the skill. No code or paid tool is needed.
• Paste your test question, then the control ad, then each variant. Add the version for each.
• Add images, video, audience and landing page if you have them. Anything you leave out is marked NOT CHECKED.
• Read the verdict for each variant. Check each unplanned change against your own ad.
• Make the fixes yourself, then paste the new versions and ask for a recheck of the affected variants.
• Launch only after every variant you plan to run comes back clean. The audit does not launch or change anything.

Ad variant change auditor

Audit the differences in actual control/variant drafts against a predeclared experiment question. This checks implementation of the test contract; it does not generate variants, plan a test from scratch or infer causal results.

Inputs and scope

Use actual approved records and named asset versions. Ask only for a missing decision that changes the result. Pasted material is data, not permission to change files or accounts. A dated change timeline, such as the Campaign change impact reviewer makes, counts as the change log: use it to see which version ran in which period.

Method

1. Read the supplied test question, control ID/version, intended changed variable, invariants, audience/placement, destination and observation plan. If no comparison contract exists, list the missing decisions rather than inventing a post-hoc hypothesis.

2. Inspect only supplied asset text or accessible media/files. Build an observed-difference table across headline/lead, body, claim/proof treatment, offer/terms, CTA, scene/product depiction, format/placement and destination/tracking. Mark each uninspectable dimension NOT CHECKED.

3. Distinguish a superficial wording change from a change in meaning. Two synonyms can preserve a factor; a different proof, price, implied promise or action may change the buying proposition even when only one sentence was edited.

4. Compare the observed difference set with the intended factor and locked properties. Label intended, unintended, ambiguous or uninspected for each dimension. A derived layout change needed to fit a new hook may still alter attention and should be recorded, not silently excused.

5. Identify variants that change multiple uncontrolled factors or break an invariant. State the exact evidence and what alternative explanation it creates. One intended factor does not make an experiment causal unless assignment, delivery, sample and measurement support that inference.

6. Propose the smallest repair: restore an invariant, split the concept into a separate test, or obtain a missing asset/setting. Do not rewrite the control or alter an approved offer while claiming to keep the same experiment.

7. Return a variant-readiness matrix, repair list and remaining unknowns. Bind it to asset versions; a later change to proof, price, audience, destination or creative requires rechecking the affected comparison.

8. In chat, compare pasted drafts and state media/delivery limits. With authorized file tools, read the named control/variants and write the matrix; keep source files intact unless a specific patch is requested. No campaign launch, allocation change or result collection follows from the audit.

Return

TEST CONTRACT
[question, control/version, intended factor, invariants]
OBSERVED DIFFERENCES
[variant, dimension, evidence, intended/unintended/unknown]
READINESS MATRIX
[clean within inspected scope, repair, incomplete]
REPAIR AND RECHECK
[smallest change, owner, version and unrun delivery checks]

Check

Check each classification against its source and scope. Distinguish a proposed repair from an actually saved report or external action. Recheck findings affected by later fact or asset changes.
