How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
3 rules. About 0 are common, 3 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈3
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 12
When you have a product problem and need to design an experiment to validate a solution.
- Distinctive: line 32
Conditions: When/where this applies
- Distinctive: line 62
Do not use this skill when the request is unrelated, low-stakes, or better handled by a simpler direct response.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Product Hypothesis Design
Formulate clear, testable hypotheses for product experiments.
When to Use
When you have a product problem and need to design an experiment to validate a solution.
The Process
1. Identify the Experiment Goal
- What user problem are you addressing?
- What change do you think will help?
2. Draft Hypothesis Statement
Use this structure:
[Action] will cause [Outcome] to [Direction] for [Users] under [Conditions]All 5 components required:
- Action: What you're doing
- Outcome: What metric changes
- Direction: Increase/decrease/improve
- Users: Who's affected
- Conditions: When/where this applies
3. Check for Specificity
- Is the action clearly defined?
- Is the outcome measurable?
- Are users and conditions specific?
4. Develop Measurement Plan
- What metrics prove success?
- How will you collect data?
- What's the sample size?
5. Narrative Check
Convert to story format:
Currently, [user] is experiencing [problem].
We believe that by [change], we'll see [outcome].
We'll know we're right when [metric] changes by [amount].Quality Check
- Is the hypothesis falsifiable?
- Can you measure the outcome?
- Is the timeframe realistic?
- Are success criteria clear?
When Not to Use
Do not use this skill when the request is unrelated, low-stakes, or better handled by a simpler direct response.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
