Second Opinion from Claude
Get a second perspective from Claude on your current work. This is useful for plans, implementation choices, bug diagnosis, code review, and final sanity checks.
Quick Usage
skills/second-opinion/codex-opinion "What issues might exist in this approach?"
git diff --staged | skills/second-opinion/codex-opinion "Review these changes for bugs or risks"
cat src/main.ts | skills/second-opinion/codex-opinion "What could be improved here?"
The wrapper script automatically:
- Runs Claude from the current working directory
- Allows read-oriented tools so Claude can inspect the codebase
- Passes along optional stdin context
- Points Claude at Codex history in
~/.codex/history.jsonl
When To Use
Use this skill when you want an external check on:
- Architecture or planning decisions
- Mid-implementation tradeoffs
- Bug diagnosis and failure modes
- Code review for correctness, maintainability, or edge cases
- Final review before handing results back to the user
Prompting Guidance
Provide:
- A short summary of the current situation
- The exact question you want Claude to answer
- Relevant code, logs, or diffs via stdin when helpful
- Constraints and what has already been considered
Prefer prompts that invite criticism rather than agreement. Examples:
What would you challenge in this approach?
Review this diff for bugs, regressions, and missing tests
What edge cases am I likely missing?
What would a skeptical senior engineer flag here?
Interpreting Results
Treat Claude's response as an independent perspective. Compare it with your own analysis, investigate disagreements, and synthesize the useful parts into the final answer for the user.
