description	Codex-native validation workflow for technology choices and architectural approaches. Use when the user wants evidence-based comparison, external validation, tradeoff analysis, or risk assessment before committing to a path.

Due Diligence

This skill is the Codex-native replacement for the Claude due-diligence workflow.

Use This Skill When

• the user wants to compare approaches or technologies
• the user wants architectural validation
• the user wants external evidence before committing
• the user wants risks, tradeoffs, and compatibility assessed

Do Not Use This Skill When

• the decision is already made and implementation should begin
• the task is purely internal codebase research with no external validation
• the question is trivial and does not justify research

Objective

Combine codebase context with external research to recommend a path grounded in evidence.

Workflow

1. Analyze current repo constraints and existing patterns.
2. Identify the decision candidates and evaluation criteria.
3. Research external evidence:
   • primary docs
   • benchmarks
   • production case studies
   • known pitfalls
4. Compare options explicitly.
5. Recommend a path and explain why.

Evaluation Dimensions

• performance
• scalability
• compatibility with the current codebase
• migration complexity
• maintainability
• operational risk

Output Structure

• codebase context
• external findings
• option comparison
• recommendation
• caveats
• fallback option

Notes

• Prefer recent, primary, and directly relevant sources.
• When browsing is required, cite sources clearly.
• Be explicit when evidence is mixed or incomplete.
