Mkt Ab Testing

What it does

When your agent uses it

• The user needs to test marketing variations
• Improve conversion rates through experimentation
• Decide between two campaign approaches — even if they say which version performs better
• Test this landing page

Example prompts

• “which version performs better”
• “test this landing page”
• “A/B test our email subject line”
• “/mkt-ab-testing”

Requirements

• Python 3

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Hypothesis: "Changing [variable] from [A] to [B] will increase [metric] by [X%] because [reasoning]"
2. 2Primary metric: ONE metric that determines winner (conversion rate, revenue per visitor, signup rate)
3. 3Guardrail metrics: Metrics that must NOT degrade (bounce rate, page load time, revenue per user)
4. 4Traffic split: 50/50 between control and variant (standard)
5. 5Sample size: Calculate before starting (see stat-ab-testing for formula)
6. 6Duration: Minimum 1-2 full business weeks (capture day-of-week effects)

What it can do on your machine

Read from SKILL.md and the folder at commit 4e7f4f8. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 1 file in scripts/ (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • python

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mkt Ab Testing loads about 1.2k tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 115 tokens; SKILL.md has 419 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~115

When it runs · the whole SKILL.md, loaded when a task matches

~1.2k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~4.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description

Design and execute marketing A/B tests for landing pages, email campaigns, ad creatives, and pricing with proper test design and result analysis. Use this skill when the user needs to test marketing variations, improve conversion rates through experimentation, or decide between two campaign approaches — even if they say 'which version performs better', 'test this landing page', 'A/B test our email subject line', or 'should we change our CTA'.

IRON LAW: One Variable at a Time

If you change the headline AND the image AND the CTA simultaneously,
you cannot know which change caused the result. Test ONE variable per
experiment. If you need to test multiple changes, use sequential tests
or multivariate testing (MVT) with sufficient traffic.

# A/B Test Plan: {Test Name}

## Hypothesis
Changing {variable} from {A} to {B} will increase {metric} by {X%} because {reasoning}.

## Design
- Primary metric: {metric}
- Guardrail: {metric(s)}
- Split: 50/50
- Sample size: {N per variant}
- Duration: {days/weeks}

## Results
| Metric | Control | Variant | Diff | CI (95%) | Significant? |
|--------|---------|---------|------|----------|-------------|
| {primary} | {value} | {value} | {±%} | [{lower}, {upper}] | Y/N |

## Decision
{Ship / Don't ship / Extend} — {rationale}
