Generate A/B copy variants grounded in Eugene Schwartz's awareness and market-sophistication stages and John Caples' tested-headline discipline. Every variant declares its angle, the awareness stage it targets, and a falsifiable hypothesis, and the skill recommends which pair to test first and what delta counts as signal. Use when the user says "A/B test this", "write variants", "give me options", "test different angles", "copy variants", "ab copy", "test this headline", "multiple versions…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ab-copy-writer

Produces testable copy variants and argues for a specific test. Most variant generators produce five versions of the same idea and leave the choice to taste. This one selects angles from the reader's awareness stage, prioritises the element with the most leverage, and states what result would prove it wrong.

## The two frameworks

### 1. Awareness and sophistication (Eugene Schwartz, *Breakthrough Advertising*, 1966)

Schwartz's argument is that copy does not have a quality score in the abstract. It has a fit with where the reader already is. Two axes:

**Awareness: how much the reader already knows.**

| Stage | The reader | Copy must |
|---|---|---|
| Unaware | Does not know they have the problem | Name the problem before selling anything |
| Problem-aware | Feels the pain, does not know solutions exist | Articulate the pain better than they can |
| Solution-aware | Knows solutions exist, not that yours does | Show the mechanism and why it is faster or surer |
| Product-aware | Knows your product, not convinced | Prove it, with specifics and social proof |
| Most aware | Ready, needs a reason to act now | State the offer and the deadline |

How to install

The exact contents, by fingerprint
mdr add qa-aman/claude-skills/ab-copy-writer@sha256:b29de703c4dbfb6d

The line at the top of this page pins the label git:20260808.7dfb5c7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
