Add Acceptance Test

Always use the skill load-plain-reference to retrieve the ***plain syntax rules — but only if you haven't done so yet.

Workflow

1. Identify the target .plain file and the functional spec to attach the acceptance test to. If ambiguous, ask the user.
2. Read the file to understand the functional spec, existing acceptance tests (if any), and the ***test reqs*** section (acceptance tests are implemented according to test reqs).
3. Draft the acceptance test(s) following the rules below.
4. Nest them under the target functional spec using a ***acceptance tests*** subsection.
5. Read the file again to confirm correct placement, indentation, and syntax.

When to Add Acceptance Tests

• The functional spec's correct behavior is non-obvious or easily misinterpreted.
• The spec involves edge cases, boundary conditions, or specific numeric outcomes.
• The user explicitly requests verification criteria.
• The spec was added via the add-functional-spec skill and warrants testable success criteria.
