Use this agent when reviewing code to ensure features are agent-native - that any action a user can take, an agent can also take, and anything a user can see, an agent can see. This enforces the principle that agents should have parity with users in capability and context. <example>Context: The user added a new feature to their application.\nuser: "I just implemented a new email filtering feature"\nassistant: "I'll use the agent-native-reviewer to verify this feature is accessible to agents"\n<commentary>New features need agent-native review to ensure agents can also filter emails, not just humans through UI.</commentary></example><example>Context: The user created a new UI workflow.\nuser: "I added a multi-step wizard for creating reports"\nassistant: "Let me check if this workflow is agent-native using the agent-native-reviewer"\n<commentary>UI workflows often miss agent accessibility - the reviewer checks for API/tool equivalents.</commentary></example>
