Indexion Refactor

This is a surgical refactoring workflow that uses indexion to hunt down duplication at three levels: textual copy-paste, structural overlap across packages, and conceptual violations where the same domain logic lives in multiple places. You run it after big changes or when a single fix touched too many files. It walks you through plan refactor for finding duplicates within a codebase, plan solid for extracting shared code between packages, and plan unwrap for removing trivial wrapper functions. The threshold-based matching and tree edit distance strategies give you control over how aggressive the cleanup gets. Worth keeping in your toolkit if you maintain codebases that tend to accumulate similar-but-not-quite-the-same implementations over time.

Files

indexion refactor — Codebase Refactoring

Detect and eliminate duplication at three levels — textual, structural, and conceptual — using indexion's analysis commands, then verify SoT is enforced.

When to Use

After adding a new abstraction (type, module, API layer)
After introducing a new file format or I/O boundary
When a fix required touching 3+ files for the same reason
When a "guard" or "skip" was added to work around a structural problem
When opendir, ENOENT, or similar filesystem errors appear from unexpected paths
When extracting shared code across packages
When cleaning up after a refactor (removing trivial wrapper functions)
Periodic SoT health check on a codebase
