Data Quality Auditor
When to use
Use this skill for data quality auditor when you need to design or repair a meaningful software test. The expected result is a test plan or verified test change.
Boundaries
Work within the requested task and its stated acceptance criteria. Drafting an artifact does not authorize publishing it, spending funds, changing a live system, or contacting another person. Identify any such action separately before taking it.
Inputs
Inspect expected behavior, failure cases, fixtures, and test environment. Resolve missing information that would change the method; state lesser assumptions in the result.
Method
- Diagnose. Identify the runtime boundary, data shape, dependencies, deployment path, and the constraint that dominates the design.
- Decide. Choose cases that catch an actual regression, including an edge case.
- Produce. Build a test plan or verified test change from the inspected material; keep assumptions distinguishable from observed facts.
Decision rules
- Compare implementation choices on correctness, compatibility, performance, operability, and reversibility. Choose against the actual workload.
- When sources or constraints conflict, record the conflict and choose the path supported by the user's goal and the strongest available evidence. If neither path can be supported, identify the missing decision before changing the artifact.
Domain rules
- Check compatibility, performance, security, and operational cost for the chosen implementation.
- Include migration and rollback steps when contracts or persisted data change.
Verification
Run the relevant checks and report failures with reproduction steps. Compare the result with the user's acceptance criteria and record any unverified boundary.
Supply the artifact, migration notes when needed, measured or tested behavior, and a rollback condition for risky changes.
Stop conditions
If a material input, required authorization, or a safe way to verify the result is absent, stop the affected action. Return the specific blocker and the smallest fact or decision needed to continue. Do not report an unrun check as passed.
Output
Provide a test plan or verified test change. Include the decisive evidence and actual verification result. Name any artifact location and unresolved issue that affects its use.
