What is the LLD Reviewer skill?

It is a specialized capability for Claude Code that simulates a professional design review meeting to validate Low-Level Design (LLD) documents against project requirements.

Can it automatically modify my design files?

No, following the principle of 'Gatekeeper Mentality,' the skill only identifies and reports issues to the author rather than rewriting the design itself.

How does the skill handle design issues?

Issues are graded as P0 (Blocking), P1 (Serious), or P2 (Suggestion). A single P0 or P1 will result in a failed review to ensure high design standards.

What documents are required for an LLD review?

To perform a complete review, you need the LLD document path and ideally the associated PRD, HLD, and API Contracts to serve as a baseline.

What is the LLD Manifest requirement?

The LLD must include a Manifest listing all modules and sections to be reviewed; without this, the skill triggers a P0 blocking issue as the scope is undefined.

Collaboration Tools

Conducts professional Low-Level Design (LLD) reviews to ensure technical feasibility and alignment with system architectures.

About

The LLD Reviewer skill acts as a virtual design auditor that simulates professional review meetings to validate low-level technical designs before implementation begins. It meticulously checks LLDs against PRDs, High-Level Designs (HLDs), and API Contracts to identify architectural drift, missing modules, or implementation risks. By enforcing a strict five-phase gate process with clear pass/fail criteria (P0-P2 levels), it ensures that engineering teams only proceed to the coding phase with high-quality, testable, and consistent design documentation that adheres to project guardrails.

Key Features

Strict 5-phase gate review process with clear exit criteria
Technical feasibility assessment including pseudocode and concurrency checks
Automated drift detection between HLD and LLD components
Detailed review reports and 'Pass Certificates' for documentation trails
6 GitHub stars
API Contract consistency validation to prevent integration errors

Use Cases

Pre-implementation technical design validation for complex features
Ensuring consistency between high-level system architecture and detailed logic
Standardizing design review quality and gatekeeping across distributed engineering teams
