What problem does it solve?

This Skill helps engineers apply a logical bug fix or change from one branch or project to another when direct cherry-pick or copy would fail due to structural, framework, or dependency differences. It focuses on extracting the fix intent and re-implementing that intent in the target codebase rather than copying code verbatim, reducing conflicts and incorrect adaptations.

Core Features & Use Cases

• Intent Extraction: Analyze commit diffs or conversation context to summarize the root cause, scope, and core behavioral change introduced by the fix.
• Mapping & Discovery: Search and locate corresponding files and modules in the target branch, highlighting missing or incompatible dependencies.
• Decision & Re-implementation: Decide between direct file copy for safe new files and guided re-implementation using the target branch's patterns, producing minimal, style-consistent changes.
• Reporting & Safety: Generate a migration report with file mappings, applied changes, and items requiring user confirmation before any modifications.
• Use Case: When a bugfix from a monorepo must be applied to a smaller repo with different utilities and imports, use this Skill to translate intent and produce a patch adapted to the target project's conventions.

Quick Start

Provide the commit or description of the fix, ask the Skill to analyze intent, locate corresponding files in the current branch, and generate a migration report with recommended changes for confirmation.
