Caveats

Published by the company that sells the agent. Treat numbers as marketing until confirmed elsewhere.

Anthropic makes Claude Code, so this is a vendor story about its own team.
Time saved is self-reported by the marketer. Ad performance results are not given.

What the agent does

Two workflows:

Ad copy. The agent reads a CSV of current ads and results, finds weak ads, and writes new headlines and descriptions within Google Ads character limits. It exports an upload-ready CSV.
Ad creative. A Figma plugin finds ad frames and swaps in new headlines and descriptions, making many variations in one click.

Why it matters

The builder was a marketer, not an engineer. Before, each variation meant copying frames and pasting text by hand. The agent removed the copy-paste work.

What to copy

Look for jobs where you copy and paste between two tools. Agents remove that well.
Put hard limits (character counts, brand words) in the prompt and check them in code.
Keep a human picking the final ads.

Starter prompt

Written by us.

Here is a CSV of our current ads with impressions, CTR, and conversions:
{csv}

1. List the 5 weakest ads and say why in one line each.
2. For each, write 3 new headlines (max 30 characters) and 2 descriptions
   (max 90 characters). Count characters and show the count.
3. Never use these words: {banned_words}.
4. Output a CSV with columns: ad_id, headline_1..3, description_1..2.
