What problem does it solve? Designing or reviewing a network topology without a structured process leads to missed requirements, weak segmentation, and risky cutovers. This Skill provides a disciplined, read-only workflow for statically reviewing proposed network designs and producing implementable architecture plans with validation gates and rollback points. ## Core Features & Use Cases - Static Design Review: Inspects supplied topologies, routing designs, and segmentation plans without connecting to devices or running live diagnostics. - Structured Architecture Output: Produces a consistent deliverable covering topology rationale, addressing and segmentation tables, routing and connectivity, management plane, phased implementation, and risk registers. - Optional Focused Skill Handoffs: References companion skills for config validation, BGP diagnostics, interface health, IOS patterns, and SSH automation, with fallback guidance when they are unavailable. - Use Case: A team planning a campus network refresh submits their requirements and existing constraints; the Skill identifies missing inputs (site count, uptime target, compliance scope), recommends a routed topology with explicit segmentation zones, and delivers a phased migration plan with rollback points. ## Quick Start Ask the assistant to review your proposed network topology and segmentation plan and produce a phased architecture design with risks and required follow-up evidence.
