Regression Test Selection

When to Use

• Use this skill when you need to select the smallest sufficient subset of existing tests that covers change risk and explain tradeoffs.
• Use it to review an existing plan, result, or evidence set and produce actionable improvements.
• Use it when context is incomplete but a bounded first pass is still valuable.

Output Format Options

• Default to Markdown for review, execution, and incremental refinement.
• When the user requests tables, CSV, JSON, or ticket fields, preserve risk, evidence, priority, and boundary information.
• For machine-consumed output, confirm the schema, enums, and required fields first.
