Documentation duplication occurs when bash commands, step-by-step procedures, and skill paths are repeated across agent definitions, lessons learned, and process documents. This Skill detects such duplication by scanning these sources and identifies exact bash commands, procedures, and hardcoded skill paths that should exist only within the Skill itself, with other documents referencing it instead.

Yes. This Skill acts as a blocking enforcement mechanism during workflow completion (such as Phase 5 finalization), preventing advancement if duplication violations are found. It promotes referencing Skills as the only source of automation, ensuring all other documentation points to the executable truth rather than repeating procedures.

Run this Skill after creating new skills, before Phase 5 finalization, when updating agent definitions or lessons learned, and during monthly audits. It scans for exact bash commands, step-by-step procedures, hardcoded skill paths, and procedural references that duplicate skills across your documentation ecosystem.

The Skill reports violations and blocks workflow completion, preventing downstream processes from proceeding. This enforcement ensures you resolve conflicts and consolidate procedures into the Skill definition before continuing, eliminating agent confusion caused by conflicting information.

Automated scanning detects exact bash commands, procedures, and skill path duplications systematically across multiple document sources—agent definitions, lessons learned, and process docs—faster and more consistently than manual review, with blocking enforcement that prevents violations from reaching production workflows.

This Skill uses standard bash utilities—grep, find, sed, and ls—to scan and identify duplication patterns. These are standard shell tools present on most systems, requiring no additional installations or specialized platforms beyond a bash environment.
