Score how varied your ad portfolio actually is — from a public ad library, without account access.

Thirty ads can average well and still be fragile, because all thirty use the same hook, the same visual treatment and the same angle. The first time that combination stops working — saturation, an algorithm change, ordinary fatigue — every asset fails at once.

Performance tells you how the portfolio is doing now. This tells you how much it can absorb before it stops.

Run it

1. Put SKILL.md in your AI tool's instructions field — Claude Project, Custom GPT, Gemini Gem, or an API system prompt.
2. Put anything in reference/ into its knowledge base or file uploads.
3. Give it a brand's ad library — tagged, or read from a public library.

What it takes

In	A brand's ad library — tagged, or read from a public library
Out	A score per dimension, a composite, and the specific gaps to fill

Missing a required input, it asks instead of guessing.

How it works

1. Starts with a 90-second look at the library as a grid, written down before any arithmetic — it's the sanity check on the numbers
2. Scores eight dimensions for both variety and evenness, so ten formats with nine of them the same concept doesn't score as diverse
3. Flags any single dimension below threshold, which is usually where the actionable gap is
4. Checks whether your diverse creative actually carries any budget, or just exists

Notes

It runs on anyone. No account access, no permission, no data sharing — a public ad library is enough. Across 40 brands in 7 verticals, 33 of 34 scored came back Concentrated or Critical. Not one came back diverse.
