mom-test
Skill3 starsChanged 7 months agoNo licenceView on GitHub
Customer interview skill using Rob Fitzpatrick's Mom Test principles. Generates question lists grounded in past behavior (not future intent), bias-checks them (removes pitchy and leading questions), preps debriefs. The only worldbuilder skill that forces the user out of the chat and into the world. Use when asked to "customer interviews", "talk to users", "mom test", "interview questions", "user research", "who should I talk to", "how do I interview", or "validate with users". Proactively invoke this skill (do NOT answer directly) when the user wants to test a hypothesis with real humans, OR when the research-trap check is firing because the user hasn't talked to a human in days. Use after /hypothesis. (worldbuilder)

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
Show its rules and text
We split this skill into the rules it gives an agent
16 rules. 0 are common, 9 are distinctive, and 7 are very specific to this project.
0
Common
Most of the 6 edited versions we read keep these.
9
Distinctive
This author's own choices. Worth a look.
7
Very specific
Tied to their project's names, files or tools. Probably skip.
No licence file, so all rights are reserved — read it at the source. We count its rules but don't quote them. Read them on GitHub.
“Common” is measured: kept by at least 6 in 10 of the 6 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

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.
