# Multi-LLM Code Review Use this skill for a real review gate, not a popularity vote or a summary-only second opinion. Dispatch review requests through the current agent's local stdio gateway MCP surface, never a direct provider CLI, shadow connector, or remote gateway when the requested validation path is stdio. ## Completion contract A required reviewer is complete only when it inspected the target and returned an evidence-backed `APPROVED_UNCONDITIONALLY`. A qualified approval, a conditional result, missing evidence, a malformed response, a timeout, or a provider error is not approval. Do not set a review-round, turn, token, price, budget, or wallclock cap. Do not use `route_request`, `select:"cheapest"`, `maxCostUsd`, `maxOutputTokens`, `maxTurns`, `maxPrice`, or a provider print deadline to reduce an exhaustive review. Continue evidence-based repair and re-review until every required healthy reviewer returns `APPROVED_UNCONDITIONALLY`, the user explicitly cancels, or it returns `BLOCKED_EXTERNAL` with a concrete external error. A blocked reviewer never becomes an implied approval. ## Discover the actual roster The gateway has seven canonical CLI provider types: Claude, Codex, Gemini (Antigravity), Grok, Mistral Vibe, Devin, and Cursor Agent. Start a full CLI review with all seven in its intended roster. Before dispatching, inspect what this gateway can actually run: ```text cli_versions() list_models() provider_tool_capabilities({cli:"claude"}) provider_tool_capab...
