When should I use The Hook Lab?

Posts are getting scrolled past in the first line, and hooks are being written on gut feel. That's the diagnostic trigger. Once installed, ask Claude for the outcome ("rewrite post openings into four scored hook variants") and the skill kicks in automatically.

How does The Hook Lab work under the hood?

The Hook Lab is part of the Brand Designer 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 Hook Lab?

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 Hook Lab 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 Hook Lab installed, you ask for what you need in plain language and Claude runs the right process without you re-explaining it.

Q: Is The Hook Lab 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/brand-designer/the-hook-lab) pulls it straight from GitHub into your project's .claude/skills/ folder. No signup, no build step, no gated tier.

Part of the Brand Designer pack

This is one of 5 Brand Designer 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. 5 best Claude design skills for brand and content walks the whole pack in the order the skills actually chain.

Install

Two ways to run it.

Pick your Claude surface. Both paths take under a minute.

Prefer one command? npx skills add sidchaudhary/gtm-skills installs the whole set via the community skills CLI. If you'd rather not run a third-party CLI, use either path below to install the ZIP directly.

Questions about The Hook Lab

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

Four scored hook variants for any post draft, each using a distinct psychological framework. 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.
