What problem does it solve? After a GSD update wipes and reinstalls workflow, command, and agent files, any local customizations you made are lost. This Skill restores those modifications by merging your backed-up copies into the newly installed versions. ## Core Features & Use Cases - Patch Detection: Locates the gsd-local-patches backup directory across multiple runtime config locations (opencode, gemini, claude) and reads backup-meta.json. - Intelligent Merge: Compares each backed-up file against the newly installed version, applies your additions, skips changes already incorporated upstream, and flags conflicts for manual resolution. - Status Reporting & Cleanup: Produces a per-file report (Merged, Skipped, Conflict) and optionally removes the patch backup directory. - Use Case: You customized a GSD agent prompt, then ran a GSD update that overwrote it. Run this Skill to merge your custom prompt sections back into the new upstream version without losing upstream improvements. ## Quick Start Reapply my saved local patches from the last GSD update and show me which files were merged or had conflicts.
