second-opinion
Most recent maintenance signal among this shortlist.
| Signal | second-opinion Cross-check the agent's own answer with independent reviewers before bringing it to the user. Use when the user says 'second opinion', 'sanity check', 'cross-check', 'am I missing something', 'stress-test', 'devil's advocate', 'run a full review', 'this is important', 'high-stakes', 'help me choose between', 'critique this', or similar. Three review styles: Devil's Advocate (single critique), Boardroom Debate (parallel multi-reviewer validation), Round-Table (multi-round brainstorm for choosing between paths). Not for factual lookups — use WebSearch for those. | Implement Implement work from an approved spec or ticket set, run focused and full tests, invoke code review, and commit the result to the current branch. | Code Review Review a branch or diff against repository standards and the originating spec in two independent analysis passes. |
