Q: Does Ad Copy Writer work with Claude Code?

We tested it with Claude Code 2.x (agent harness) on Jul 17, 2026. Verdict: Tested · Works. Ran it for a project-management tool: it enforced Google's RSA spec, emitting 15 headlines all inside the 30-char cap and 4 descriptions under 90, where an unaided pass gave 3 headlines with 2 over the limit. Prompt-only, but the per-platform character rules and three-angle structure are a real, repeatable lift over freehand copy.
