ab-hook-tester

Generates two genuinely distinct hook variants for the same reel so you can post-test which opening actually wins. Use when the user says "give me two hooks to test", "A/B this hook", "which opening should I use", "hook variants".

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by Ootto-AI on GitHub. Read the source before you install it.

Installation

Install the Ab Hook Tester AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/Ootto-AI/claude-content-skills/tree/main/skills/ab-hook-tester
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/Ootto-AI/claude-content-skills.git /tmp/claude-content-skills
mkdir -p .claude/skills
cp -r /tmp/claude-content-skills/skills/ab-hook-tester .claude/skills/ab-hook-tester

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Ab Hook Tester in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Ab Hook Tester on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Ab Hook Tester is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

A/B Hook Tester — two hooks, one variable, a real answer

Generates two genuinely distinct hook variants for the same reel so you can post-test which opening actually wins.

When to use

You have a reel and two instincts about how to open it.

What you'll need

The script or the idea, plus what you're optimising for (retention, saves, DMs).

Instructions

Give Claude the input and run this.


You are my hook tester. Reel: [paste script or idea]. I care most about: [retention/saves/DMs].

Give me TWO hooks that use DIFFERENT MECHANISMS — not one hook reworded:
- HOOK A: [mechanism, e.g. result-first] — the exact on-screen text + spoken line.
- HOOK B: [a different mechanism, e.g. objection-first] — same.

Then:
1. HYPOTHESIS: what I learn if A wins, and what I learn if B wins.
2. HOLD CONSTANT: everything that must stay identical (cover, length, caption, posting time).
3. READ: which metric decides it, and at what point (3s retention, not likes).
4. SAMPLE: roughly how many views before the result means anything.

If both hooks pull the same lever, say so and replace one.

Honesty: One variable. If the cover or caption changes too, it isn't a test — it's two different reels.

Next: reel-scripter → cover-thumbnail-brief

Frequently asked questions

What does the Ab Hook Tester AI skill do?

Why use Ab Hook Tester on TypingMind?

Because you install it once and use it with any model. Ab Hook Tester is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Ab Hook Tester in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Ootto-AI/claude-content-skills/tree/main/skills/ab-hook-tester. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Ab Hook Tester?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Ab Hook Tester?

As many as you like. As long as a model supports skills, you can use Ab Hook Tester with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Ab Hook Tester AI skill free?

Yes. It is published on GitHub by Ootto-AI under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
