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 gtmagents on GitHub. Read the source before you install it.

Installation

Install the Ab Testing 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/gtmagents/gtm-agents/tree/main/plugins/email-marketing/skills/ab-testing
Enable the skill in any chat where you want it available.

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/gtmagents/gtm-agents.git /tmp/gtm-agents
mkdir -p .claude/skills
cp -r /tmp/gtm-agents/plugins/email-marketing/skills/ab-testing .claude/skills/ab-testing

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

Use it in TypingMind

Enable Ab Testing 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 Testing 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 Testing 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.

Experimentation & A/B Testing Skill

When to Use

Validating new subject lines or creative.
Testing segmentation hypotheses (persona vs behavior).
Optimizing cadence, timing, or automation triggers.

Framework

Hypothesis – define expected uplift + rationale.
Metric Selection – primary (open/click/conv) + guardrails (unsubs, spam).
Sample Sizing – ensure stat significance (min 500 recipients per variant or use power calculator).
Execution – randomize, keep variants isolated, limit simultaneous tests.
Analysis – use z-test or Bayesian uplift; document learnings.

Templates

Experiment brief (hypothesis, segments, KPI, risk guardrails).
Variant table (control vs test inputs, creative asset links, owner).
Calculator sheet for minimum detectable effect + sample size.
Post-test debrief doc capturing learnings + rollout plan.

Experiment Ideas

Subject line vs preview text combos.
CTA placement (hero vs footer).
Personalization depth (basic vs dynamic modules).
Wait times between touches.

Tips

Run no more than two tests per journey simultaneously.
Recycle learnings into playbooks + automation templates.
Segment results by persona to catch hidden signals.

Frequently asked questions

What does the Ab Testing AI skill do?

Use when designing experiments for subject lines, offers, cadences, or journeys.

Why use Ab Testing on TypingMind?

Because you install it once and use it with any model. Ab Testing 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 Testing in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/gtmagents/gtm-agents/tree/main/plugins/email-marketing/skills/ab-testing. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Ab Testing?

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 Testing?

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

Is the Ab Testing AI skill free?

Yes. It is published on GitHub by gtmagents under the Apache-2.0 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.
