Each tool targets a distinct stage of the design pipeline: requirement analysis, token extraction, design generation, and visual audit. Input types and outputs are clearly differentiated, leaving no ambiguity about which tool to use.

All four tools follow a consistent snake_case verb_noun pattern: analyze_requirement, extract_tokens, generate_design, audit_visual. The naming is predictable and uniform throughout.

Four tools map cleanly onto a coherent design workflow. The count sits well within the 3-15 sweet spot, and each tool has a clear, non-redundant role.

The surface covers the full end-to-end workflow: parse requirements, extract tokens, generate a design, and audit the visual result. A minor gap exists in that there is no explicit tool to refine or fix the design based on audit findings, though an agent could work around this by re-invoking generate_design.
