Review Gang

Independently audit existing code by spawning concern-specific reviewer subagents, then synthesize one evidence-backed ship decision.

Contract

Spawn at least two reviewer personas as separate subagents every time
Treat invocation of review-gang, $review-gang, or the Review Gang tile as authorization to use reviewer subagents; if their tooling is not visible, discover or load it once, then report blocked if it remains unavailable unless the user explicitly allows a sequential fallback
Scale the reviewer set to the change: a tiny low-risk diff gets general plus one relevant specialist; normal changes get general, tests, silent-failures, and code-shape; high-risk changes add only distinct specialists
Keep findings risk-focused, evidence-backed, severity-ordered, and free of low-value nits
Block when missing context or proof prevents an honest verdict; otherwise name the unverified surface and adjust the verdict
Do not use this lane to self-check a change you just authored
