Spec Gap Analysis
Automates the comparison of specification documents against source code to identify unimplemented features and implementation drift.
Spec Gap Analysis is a specialized Claude Code skill designed to bridge the divide between architectural planning and actual implementation. By automatically locating specification files, ADRs, and blueprints, it extracts functional claims and cross-references them with the codebase using advanced search patterns. The skill provides a comprehensive report and a drift score (0-100), highlighting 'ghost features' that were planned but never built, and 'invisible features' that exist in code but lack documentation. This tool is essential for maintaining high-quality documentation, ensuring project requirements are fully met, and conducting rigorous architectural audits.
