What it does
Experiment is an agent skill from menkesu/awesome-pm-skills. Designs, sanity-checks and reads out product experiments (A/B tests, holdouts, pre/post, geo and incrementality tests) and produces an experiment brief plus a readout with a ship / hold / replicate call. Use when you ask 'should we A/B test this', 'how long should the test run', 'is this result real', 'sample size', 'stat sig', 'SRM', 'holdout', 'our win rate is low', or need to grade an existing test plan or readout. Draws on 191 insights from 71 Lenny's Podcast guests, led by Ronny Kohavi, Ramesh Johari and…
Its SKILL.md is about 5.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files and assets (for example `references/frameworks.md` and `references/quotes.md`).
It sits in Marketing & SEO, covering A/B testing, Experimental design and Test generation. The repository describes itself as: Product management workflows grounded in Lenny's Podcast, for Claude Code, Codex, and Cursor.
When your agent uses it
- You ask should we A/B test this
- How long should the test run
- Is this result real
- Our win rate is low
Example prompts
- “should we A/B test this”
- “how long should the test run”
- “is this result real”
- “/experiment”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Diagnose (ask before answering)
- Pick the play
- Run it
What it can do on your machine
Read from SKILL.md and the folder at commit c1b6e2d. 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 (its code samples are markdown).
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
Experiment loads about 5.2k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 135 tokens; SKILL.md has 2,973 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,973 words (~5,165 tokens).
“Turn an idea into a pre-registered experiment, catch the ways it can lie to you, and end with a decision you can defend. Built from 191 insights from 71 Lenny's Podcast guests. Lead team: Ronny Kohavi, Ramesh Johari, Archie Abrams.”

Experiment is an agent skill from menkesu/awesome-pm-skills. Designs, sanity-checks and reads out product experiments (A/B tests, holdouts, pre/post, geo and incrementality tests) and produces an experiment brief plus a readout with a ship / hold / replicate call.
When should I use Experiment?
Experiment fits situations like: you ask should we A/B test this; how long should the test run; is this result real; our win rate is low.
How do I install Experiment in Claude Code?
Run `npx skills add menkesu/awesome-pm-skills --skill experiment -a claude-code`. Or copy the skill folder (skills/experiment in menkesu/awesome-pm-skills) into .claude/skills/experiment in your project. Claude Code loads it when a task matches its description.
How do I install Experiment in Codex?
Run `npx skills add menkesu/awesome-pm-skills --skill experiment -a codex`. Or copy the skill folder (skills/experiment in menkesu/awesome-pm-skills) into .agents/skills/experiment in your project. Codex loads it when a task matches its description.
Can I use Experiment in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add menkesu/awesome-pm-skills --skill experiment -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/experiment, .gemini/skills/experiment, .github/skills/experiment and .opencode/skills/experiment in your project.
What does Experiment need to run?
SKILL.md names no scripts, command-line tools or credentials: Experiment is instructions for the agent only.
Does Experiment access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Experiment safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Experiment use?
Experiment has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Experiment use?
About 5.2k tokens (SKILL.md is roughly 21k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 8.2k tokens, read only when the agent opens those files.
What are the alternatives to Experiment?
Skills that share tags, products or a category with Experiment: Ab Test Architect (LeoYeAI/openclaw-master-skills, 2.2k stars), Ab Test Planner (mohitagw15856/pm-claude-skills, 1.4k stars), Ad Test Designer (aaron-he-zhu/aaron-marketing-skills, 2.9k stars) and Ab Test Analyzer (irinabuht12-oss/marketing-skills, 4k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
