Is this skill a blocking gate in my workflow?

No, it is advisory. It provides quality recommendations and findings, allowing the user to decide whether to address the identified issues or proceed.

What are the 3 Cs of specification validation?

The 3 Cs stand for Completeness (all content is present), Consistency (internal and cross-document alignment), and Correctness (accuracy and technical feasibility).

Can I use this to check my code against a PRD?

Yes, the Comparison Validation mode identifies requirements in your documentation and checks your implementation for coverage and deviations.

How does this skill handle vague language?

It scans for patterns like hedge words (should, might), vague quantifiers (fast, many), and passive voice to provide an ambiguity score and concrete recommendations.

Security & Testing

Validates software specifications, implementations, and architectural alignment using the 3 Cs framework to ensure project quality.

The Specification Validation skill serves as an advisory layer for development workflows, ensuring that project requirements (PRDs), system designs (SDDs), and implementation plans are complete, consistent, and correct. It acts as a pre-implementation gate and post-implementation auditor, identifying vague language patterns, detecting cross-document contradictions, and verifying that code matches original design intent. By using automated ambiguity scoring and traceability matrices, it helps developers catch errors early in the lifecycle and maintain high standards for both documentation and code.
