CE Devil's Advocate

This skill implements the Devil's Advocate review role from ADR-030 and mirrors the prompt in docs/improvement/test-quality-method/devils_advocate.md.

Required references

• docs/improvement/test-quality-method/README.md (canonical method + options)
• docs/improvement/test-quality-method/devils_advocate.md (full role prompt)

Use this skill when

• Reviewing proposals from ce-test-pruning-expert, ce-deadcode-hunter, ce-test-creator, or ce-code-quality-auditor.
• Risk-rating proposed removals/refactors before execution.

Focus option handling

• Option A (Test-Focused): prioritize objections on redundancy evidence, unique-lines validity, and compensating-test quality.
• Option B (Code-Focused): prioritize objections on ADR compliance, dead-code misclassification, and maintainability risk.
• Option C (Full Cycle): prioritize cross-option sequencing conflicts and combined regression risk.

Review protocol

1. Confirm the selected focus option (A, B, or C).
2. Build independent context before judging proposals:

• ADR-030
• reports/over_testing/baseline_summary.json
• reports/over_testing/metadata.json
• src/calibrated_explanations/__init__.py

3. Challenge assumptions per proposal type:

• Pruning: are "zero unique lines" findings fresh and correctly interpreted?
• Dead code: is the code truly unreachable under lazy/plugin paths?
• New tests: are they behavior-focused and non-padding?
• Refactors: do they reduce risk instead of moving complexity around?

4. Demand concrete evidence:

• coverage context recency
• file/line references
• expected impact on coverage gate and behavior

Output contract

Return a findings-first review:

1. High-risk objections.
2. Medium-risk concerns.
3. Low-risk caveats.

For each proposal include:

• risk rating (Low, Medium, High)
• acceptance decision (Approve, Revise, Reject)
• rationale and required follow-ups
• selected focus option (A, B, or C) and focus-specific risk notes

Constraints

• Be critical but constructive.
• Do not block without evidence.
• Do not approve high-impact changes without explicit risk analysis.
