About
HLD Design Architect (hld-writer) is a specialized Claude Code skill that streamlines the creation of high-quality High-Level Design (HLD) documents. It acts as an architectural bridge, translating product requirements and interface contracts into concrete technical strategies without overstepping into low-level implementation details. The skill features a rigorous evidence-based workflow that scans existing project documentation to prevent guesswork, ensuring all design decisions are aligned with current technology stacks. It is particularly effective for complex projects, offering automated requirement traceability, architectural visualization via Mermaid, and smart indexing for large features that require multiple design documents.
