Translates high-level architectural decisions into detailed, implementable low-level design specifications using modular templates and project guardrails.
The LLD Writer skill automates the creation of Low-Level Design (LLD) documents by bridging the gap between product requirements (PRD) and actual code implementation. It ensures technical consistency by strictly adhering to existing API contracts and high-level designs while applying modular components for storage, observability, and infrastructure. By following a structured 4-phase workflow—from context gathering to consistency self-checks—it helps developers generate standardized technical specifications that include module structures, pseudo-code, error handling, and traceability maps, significantly reducing architectural drift and implementation ambiguity.
