golang-refactoring

Golang refactoring — the safe, at-scale process for restructuring existing Go code: a coverage-adaptive safety net, tool-driven behavior-preserving transforms (gopls Rename/Inline/Extract, gofmt -r, eg, gopatch, go/analysis fixers), the Fowler catalog mapped to Go, breaking import cycles, moving types across packages, and a human-in-the-loop workflow of small stacked PRs on a refactoring branch. Apply when code is hard to maintain, a function/type has grown too large, a code smell needs fixing, adding a feature is blocked by the current structure, or the user asks to clean up, refactor, or improve Go code — also for renaming at scale, extracting functions/interfaces, moving code between packages, splitting packages, or planning a multi-step refactor.
