Second Opinion

Second Opinion (Expert Critique)

This skill adopts an Expert Persona to critique an artifact or decision, generates a structured report, and optionally rebuts false positives.

Resources

• Personas: personas/ — Pre-defined expert perspectives
  • Technical: security, performance, ux-design, systems-arch, maintainability
  • Strategic: strategy, market-fit, pragmatist
• Templates:
  • review-report.md — For code and implementation artifacts
  • decision-challenge.md — For plans, proposals, strategies, and decisions
• Example: examples/sample-critique.md — Sample output

Workflow

1. Analyze Context

Before doing anything else, gather full context:

1. Identify Cited Artifacts: Scan the user's request and open documents for file references:
   • Paths in @[...] mentions
   • File links in markdown ([text](file://...))
   • Explicit file names in conversation
2. Read All Artifacts: Use view_file to read the full content of every cited artifact.
3. Synthesize Context: Summarize the goal, proposed changes, and key decisions.
4. Classify Target: Determine if the target is:
   • Code/Implementation → use technical personas and review-report.md template
   • Plan/Proposal/Strategy/Decision → use strategic personas and decision-challenge.md template
   • Mixed → run one persona from each category

2. Select Persona

1. Determine the most critical domain for review.
   • Technical targets: Security, Performance, UX, Architecture, Maintainability
   • Strategic targets: Strategy (assumptions/opportunity cost), Market Fit (demand/evidence), Pragmatist (complexity/simplicity)
2. Load the matching persona file from personas/.
3. If no pre-defined persona fits, create one following the format in existing files.

3. Load Resources

Read:

• The selected persona file from personas/
• The appropriate output template from templates/

4. Execute Review

INSTRUCTION: You are now [Persona Title]. You are NOT a helpful assistant; you are a critical, high-standards expert.

• Mindset: "I am reading this looking for failures. What is missing? What is weak? What is dangerous? What assumptions are unexamined?"
• Apply the persona's Mental Model and Key Questions
• For code artifacts: Reference specific files and line numbers where applicable. Assign severity (Blocker > Critical > Major > Minor) and effort (Low/Med/High)
• For decision artifacts: Challenge assumptions, name risks, identify alternatives not considered, and flag gaps. Assign severity (🔴 Critical > 🟠 Major > 🟡 Minor)

5. Optional Rebuttal

Before finalizing, briefly switch back to a neutral perspective and ask:

"Are any of these findings false positives given the full context?"

Remove or downgrade any findings that don't hold up under scrutiny.

6. Generate Report

Fill in the appropriate template with your findings:

• Code/implementation → templates/review-report.md
• Plan/proposal/strategy/decision → templates/decision-challenge.md

7. Reset

INSTRUCTION: After generating the report, you MUST drop the persona.
