Browser-local tool
Turn a tool claim into a testable plan.
Declare the question, environment, expected behavior, negative case, command, evidence, and limits before the run. The builder generates a portable JSON plan in your browser.
No account, analytics, server request, or browser storage. Your entries stay in this page unless you copy or download the generated file.
JSON Schema / v0.1What this tool does not do
It plans the run. It does not prove the result.
A complete form can still describe a weak test. Review the fixture, run both cases, keep the raw output, disclose conflicts, and reduce the conclusion when the environment or evidence is incomplete.
