What problem does it solve? When a canonical file, path, ID, schema, or generator changes, stale references and untouched consumers often survive unnoticed, causing new sessions or automation to treat outdated files as current truth. This Skill systematically detects stale references, orphaned links, missing propagation, content drift, and outdated derivatives before merge or release. ## Core Features & Use Cases - Impact Mapping and Reference Scanning: Builds an impact map from changed canonical sources to direct and indirect consumers, then scans for stale paths, IDs, commands, and orphaned references across code, Markdown links, JSON paths, and workflow files. - Derivative and Propagation Verification: Checks that manifests, hashes, generated outputs, tests, and templates were regenerated or updated after canonical changes, and classifies untouched consumers as defects or justified. - Use Case: After renaming a Skill ID and updating the registry, run this audit to find every active document, test fixture, and template still referencing the old ID, while preserving intentional legacy aliases and historical records. ## Quick Start Audit the current diff for stale references and missing propagation of the renamed Skill ID across all active documents, registries, tests, and templates.
