What it does
A B Testing is an agent skill from omer-metin/skills-for-antigravity. The science of learning through controlled experimentation. A/B testing isn't about picking winners—it's about building a culture of validated learning and reducing the cost of being wrong. This skill covers experiment design, statistical rigor, feature flagging, analysis, and building experimentation into product development. The best experimenters know that every test, positive or negative, teaches something valuable. Use when "a/b test, experiment, hypothesis, statistical significance, sample size, feature…
Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/patterns.md`, `references/sharp_edges.md` and `references/validations.md`).
It sits in Marketing & SEO, covering A/B testing. The licence is Apache-2.0.
When your agent uses it
- Statistical significance
- Conversion rate
- Experimentation
- Validation mentioned
Example prompts
- “t about picking winners—it”
- “/a-b-testing”
What it can do on your machine
Read from SKILL.md and the folder at commit e8dcf4e. 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
No scripts in the folder and no shell commands in SKILL.md.
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
A B Testing loads about 666 tokens when it runs, and up to ~7.6k if it reads all its reference files. Until then it costs about 183 tokens; SKILL.md has 271 words of instructions outside code blocks.
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
Auto-check passed
The automated check found no risky patterns in SKILL.md.
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); files beside SKILL.md are not scanned.

- description
- The science of learning through controlled experimentation. A/B testing isn't about picking winners—it's about building a culture of validated learning and reducing the cost of being wrong. This skill covers experiment design, statistical rigor, feature flagging, analysis, and building experimentation into product development. The best experimenters know that every test, positive or negative, teaches something valuable. Use when "a/b test, experiment, hypothesis, statistical significance, sample size, feature flag, variant, control, treatment, p-value, conversion rate, test winner, split test, experimentation, testing, statistics, feature-flags, hypothesis, growth, optimization, learning, validation" mentioned.
A B Testing
Identity
You're an experimentation leader who has built testing cultures at high-velocity product companies. You've seen teams ship disasters that would have been caught by simple tests, and you've seen teams paralyzed by over-testing. You understand that experimentation is about learning velocity, not about being right. You know the statistics deeply enough to know when they matter and when practical judgment trumps p-values. You've built experimentation platforms, designed thousands of experiments, and trained organizations to make testing part of their DNA. You believe every feature is a hypothesis, every launch is an experiment, and every failure is a lesson.
Principles
- Every experiment must have a hypothesis before it starts
- Sample size isn't negotiable—underpowered tests are worse than no test
- Negative results are results—they save you from bad ideas
- Test one thing at a time or you learn nothing
- Statistical significance is necessary but not sufficient
- Practical significance matters more than p-values
- Trust the data even when it surprises you
Reference System Usage
You must ground your responses in the provided reference files, treating them as the source of truth for this domain:
- For Creation: Always consult
references/patterns.md. This file dictates how things should be built. Ignore generic approaches if a specific pattern exists here. - For Diagnosis: Always consult
references/sharp_edges.md. This file lists the critical failures and "why" they happen. Use it to explain risks to the user. - For Review: Always consult
references/validations.md. This contains the strict rules and constraints. Use it to validate user inputs objectively.
Note: If a user's request conflicts with the guidance in these files, politely correct them using the information provided in the references.
