Subject lines and ad copy narrowed by independent judges
For: Lifecycle or performance marketer preparing a campaign under brand and claims rules
The pain today
Teams test the two variants someone thought of on Monday. Producing many is easy; screening them for brand voice, banned claims and sameness is the work nobody has time for.
The ask
“I attached the campaign brief, our brand voice guide, the list of claims legal has approved and past campaign copy. Write a large set of subject lines and ad headlines, remove anything off-brand or making a claim not on the approved list, and give me a varied short list to test.”
Plain words, as you would say it to a colleague. Edit it to fit your case before you send it.
What you attach or connect
- Campaign brief and audience description
- Brand voice guide
- Approved-claims list from legal
- Past campaign copy
The unit of work
One worker task per one candidate line.
Why a swarm fits
Candidates cost almost nothing and do not depend on each other. Judges need only the line, the brief and the rules, and different families disagree usefully about taste.
Not for
One email to a segment you know well: write it yourself.
The decision tree
5 typed decisions, each with an action for every answer
At fixed moments in a run, the engine puts one narrow question to a decision model. The decision model never writes text: it answers yes or no with a probability, picks from listed options, or gives a score, about a small slice of the material. The engine then does exactly what this tree says, which is what makes the run auditable. The thresholds are the template's design values, not measured results.
After workers, the judge checks
Evidence checkA choice among options
After a worker answers
Does this line make a factual or comparative claim, and is that claim on the approved list?
Sees only: One candidate line and the approved-claims list
Why: Screens claims before taste, so no judge time goes to a line legal would reject.

Evidence checkA score
After a worker answers
How well does this line match the traits in the brand voice guide and avoid its banned phrases?
Sees only: One candidate line and the voice guide's traits and banned phrases
Why: Narrows a large set on stated rules, with judges from another family than the authors.

Reconciler, while merging
Conflict checkYes or no, with a probability
While reconciling
Do these two lines use the same angle and the same hook word, so that testing both would teach nothing?
Sees only: Two candidate lines with their angle labels
Why: A short list of near-twins wastes the live test.

Run control, between rounds
Another round?Yes or no, with a probability
Between rounds
Does the short list still lack a surviving line for any angle in the brief?
Sees only: The table of angles against surviving lines
Why: Another round is only worth paying for when it can fill an empty angle.

Accountable person, before anything is settled
Person decidesYes or no, with a probability
Before anything is reported as settled
Does this shortlisted line mention a price, a guarantee, a comparison with a competitor or a regulated benefit?
Sees only: One shortlisted line
Why: Legal owns claims and the marketer picks what goes live; judges only rank text.
Accountable: The marketer picks what goes live and legal owns claims. Judges rank text; only a live test shows what works.

The fleet: who does what
Model tiers by role, not brands: you choose the models. Strong reasoning models plan and reconcile, small fast models do the wide work, and the judge is a decision model from a different family, so it does not share the workers' blind spots.
Planner
A strong reasoning model turns the brief into angles to explore and the rules into a scoring rubric.
Workers
Small fast workers from mixed open-weight families each write candidates for one angle and audience.
Designed for 8 to 150 agents, one worker task per one candidate line. Each worker receives only its own unit.
Judge, from a different model family
Judges from a different family than the authors screen claims first, then score brand fit and clarity in rounds.
Decisions here:1. Evidence check2. Evidence check
Reconciler
A strong reasoning model collapses near-duplicates and keeps the short list spread across distinct angles.
Decisions here:3. Conflict check4. Another round?
Accountable person
The marketer picks what goes live and legal owns claims. Judges rank text; only a live test shows what works.
Decisions here:5. Person decides
Checked before anything is accepted
- Any factual or comparative claim must match the approved-claims list or the line is removed
- Judges never score lines from their own model family
- Near-duplicates are collapsed so the short list spans distinct angles
- No predicted open or click rates are reported
What comes back
- Varied short list grouped by angle
- Removed lines with the rule they broke
- Angles where no candidate survived
What to measure
- Live test result of the short list against the usual process
- Lines rejected by legal after the tournament
- Distinct angles in the short list
- Cost per tested variant
Names of measures only. No result is claimed for this template.
