AIRichardFormsAIJasonAI Code Review
A test file contains two different investments: what you learned
should be tested, and the mechanics you wrote to reach it.
When the mechanics break, teams often lose patience with both.
/carbon-tests gives CARBON a durable local library of
test intent. You can define a case in natural language, manage it
visually, import existing assets, and retain its setup, expectations,
evidence requirements, and execution history.
Preserve what the old test
knew
Imagine a Selenium case that verifies a discount cannot exceed the
order total. Its selector is outdated, but the business rule is still
valuable.
An import should retain the source and the assertion, identify what
needs clarification, and adapt the execution path where appropriate. It
should not turn a precise price rule into “checkout looks okay.” Exact
values, permissions, and wire contracts remain exact when they
matter.
CARBON's import-and-bake workflow executes converted cases through an
available safe adapter and classifies non-passes. A bad test definition,
broken environment, and product defect need different responses.
Repairing a converted definition does not authorize a product
change.
Make the library usable
/carbon-tests import the local checkout test export; preserve its assertions and show the readiness gaps before execution
The protected local UI supports creating, editing, duplicating,
activating, archiving, restoring, and exporting cases. New definitions
are drafts unless activation is requested. Active intent tests can
participate in subsequent CARBON plans.
This is not a promise that natural language removes ambiguity. It
gives ambiguity a place to be resolved while preserving the testing
knowledge you already paid to acquire.

coding agent such as Claude, Codex, or Cursor.
