name	design-test-case
description	Design one `verification-check-format-v0.1` full-mode test case from a requirement, bug report, or desired behavior description.

Design Test Case

Use this skill when the user gives a requirement, bug report, task brief, or desired behavior and needs one test case, but has not already provided one selected full-mode verification check.

Read ../write-verification-check/SKILL.md. Read framework_checkout_root/src/references/test-case-implementation-order.md.

Selection

Design exactly one materially distinct target behavior case. For bugs, select the corrected target behavior; use the broken behavior only as evidence of the violated obligation. For new behavior, select the stable desired behavior and apply framework_checkout_root/src/references/test-case-implementation-order.md when several valid cases are implied. If several independent obligations are implied and the target case is not selected, ask which one to design.

Delegation

Before mapping Feature, resolve the verified object from explicit user input, an existing artifact Feature, a named endpoint, API surface, component, operation, or explicitly planned target surface. If no verified object can be resolved, ask for the target surface instead of inventing a component-like SUT. For new behavior, prefer the stable existing boundary or explicitly planned boundary over an inferred internal component. Map the selected obligation to Feature, Rule, optional named Example, Given, When, and Then. Then render through ../write-verification-check/SKILL.md. Do not add sibling rules or examples unless the user explicitly asks for more than one case.

Scope Boundary

This skill is design-only. Do not create, modify, plan, or announce test code or production code. After returning or writing the verification case stop.

Output

When invoked by another skill as an internal step, return the rendered case to that caller and do not write files. If the resolved output path is 030-test-cases-new.*, update that cases artifact instead of returning the case inline. In an existing cases artifact, add only the new case under the added-cases section. If that section already contains a source block for the same Feature, insert only the new Rule into that block. Otherwise add one source block in the artifact's existing container format. Preserve all other sections and cases. If the resolved output path is not a cases artifact, write only the case text to that file. If no output path is resolved, return only one full-mode verification-check-format-v0.1 case, or the missing selection issue.
