Does this skill replace unit testing?

No, it is part of a larger workflow. While sdd-review checks for specification fidelity, you should still use tools like run-tests to verify functional correctness.

Can I review specific tasks or only whole projects?

You can scope the review to a single task for surgical validation or an entire phase for a comprehensive compliance audit.

How does it categorize findings?

It assesses code into four categories: Exact Match, Minor Deviation (low impact), Major Deviation (significant functional difference), or Missing (feature not implemented).

What is the primary purpose of the sdd-review skill?

The sdd-review skill automates the comparison between your source code and its technical specifications to ensure that the implementation matches the plan exactly.

How long does a fidelity review take to run?

Because it performs a deep AI-powered analysis, a review can take up to 5 minutes to complete for a thorough assessment.

Security & Testing

Reviews implementation fidelity against specifications by comparing actual code to requirements and identifying deviations.

The sdd-review skill is a core component of the Spec-Driven Development (SDD) workflow, designed to ensure that code implementations perfectly align with their architectural requirements. By combining structural verification via Language Server Protocol (LSP) with AI-powered analysis through MCP, the skill identifies missing features, minor deviations, and major functional mismatches. It provides developers with detailed compliance reports for specific tasks or entire project phases, making it an essential tool for maintaining high code quality and consistency across complex development cycles.

Key Features

01Structural pre-checking using Language Server Protocol (LSP)
