Do I need external tools to use this skill?

Yes, this skill requires the 'openspec' CLI to be installed and available in your environment to fetch change artifacts and metadata.

How does it identify incomplete tasks?

It parses your tasks.md file for markdown checkboxes and flags any unchecked items as CRITICAL issues that should be addressed before the change is archived.

What is OpenSpec Verify Change?

It is a specialized Claude Code skill that compares your current code implementation against defined specifications, tasks, and design documents to ensure everything is built as intended.

Can I use this for any project?

This skill is specifically optimized for projects utilizing the OpenSpec workflow for managing software changes and requirement artifacts.

What does 'Coherence' mean in the verification report?

Coherence checks if the implementation follows the architectural decisions documented in your design files and maintains consistency with existing project patterns.

Security & Testing

Validates that code implementations align perfectly with specification, task, and design artifacts before final archiving.

This skill automates the verification process for spec-driven development by comparing code changes against OpenSpec artifacts. It evaluates work across three dimensions—completeness, correctness, and coherence—identifying missing requirements, divergent design patterns, and incomplete tasks. By providing a structured report with prioritized issues ranging from critical blockers to minor suggestions, it ensures high-quality deployments and maintains a clean audit trail between initial requirements and the final implementation.
