falsifiable-testing
Skill9 starsChanged 4 months agoLicence not identifiedView on GitHub
Write tests that can actually fail, and prove it — see the test red before you trust it green, break the code deliberately as a negative control, and strengthen the oracle from "it ran" to "it is right". Use whenever tests are being written, reviewed, fixed, or relied on: "add tests for this", "write unit tests", "the tests pass", "improve coverage", "this test is flaky", "why didn't the tests catch this", "mock this out", "update the snapshot", or a PR whose diff adds test files. Also trigger when a bug reached production through a tested code path, when a test suite is being used as evidence that a change is safe, or when coverage numbers are cited as quality. Covers oracle strength, negative controls, mock discipline, flake diagnosis, and the tests-that-cannot-fail taxonomy. It does not pick frameworks and does not chase coverage percentages.

The file
We split this skill into the rules it gives an agent
12 rules. About 0 are common, 12 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈12
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
The licence could not be identified — read it at the source. We count its rules but don't quote them. Read them on GitHub.
≈ “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.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
Reviews can't be read right now.
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.
