When should I use The Copy Formula Picker?

The copy gets glanced at but not clicked, and nobody can say which beat is missing. That's the diagnostic trigger. Once installed, ask Claude for the outcome ("pick the right copy formula for the placement and write it") and the skill kicks in automatically.

How does The Copy Formula Picker work under the hood?

The Copy Formula Picker is part of the Performance Marketer pack in Sid Chaudhary's gtm-skills repo. When invoked, Claude reads the SKILL.md, pulls your shared product-context (ICP, brand voice, scoring model), and produces a structured output. No prompt engineering on your side.

Do I need Claude Code to run The Copy Formula Picker?

Claude Code is the fastest path since it auto-loads local skill folders. The same SKILL.md also runs in Claude Desktop and claude.ai Projects - upload the zip in Capabilities. See the install options below for both paths.

How is The Copy Formula Picker different from just prompting Claude?

A skill is a folder with a SKILL.md file plus reference material - real methodology, frameworks, and benchmarks Claude loads on demand. A prompt is text you paste every time. With The Copy Formula Picker installed, you ask for what you need in plain language and Claude runs the right process without you re-explaining it.

Q: Is The Copy Formula Picker really free?

Yes. The full gtm-skills repo is MIT licensed on GitHub. Clone it, fork it, modify it. Running the install command (npx skills add sidchaudhary/gtm-skills/skills/performance-marketer/the-copy-formula-picker) pulls it straight from GitHub into your project's .claude/skills/ folder. No signup, no build step, no gated tier.

Part of the Performance Marketer pack

This is one of 30 Performance Marketer skills. They chain - the order you run them in changes what you get, and running one in isolation usually means re-answering setup another skill already captured. Will AI replace performance marketers? walks the whole pack in the order the skills actually chain.

Questions about The Copy Formula Picker

Everything you need before installing, plus how the skill actually behaves once Claude picks it up.

Chooses the two best-fit formulas for a placement, writes both, and labels every structural beat inline so the formula is visible. Also diagnoses copy that reads fine and never converts. It's a Claude Agent Skill - a folder with a SKILL.md file and reference material - so Claude loads the methodology on demand when you ask for what you need in plain language, instead of you pasting a template.
