Second Opinion

Spawns an isolated critic subagent to find problems with the current plan or proposal. The critic reads the codebase to verify the plan's claims — it doesn't just reason about them abstractly. After the critique, the main agent must make hard calls and show concrete changes, not hand-wave.

Workflow

Activation rules

Use this skill when:

• The plan has non-trivial risk (data loss, outages, security, correctness regressions).
• The work spans multiple files/components or changes behavior contracts.
• The user explicitly asks for a second opinion or pressure test.
