About This Skill
What it does
This skill enables AI agents to generate and display visual side-by-side comparisons of code changes. It allows agents to highlight specific modifications, additions, and deletions directly within the chat interface rather than just outputting raw text diffs.
When to use it
- Reviewing complex refactoring tasks where context is vital for understanding logic shifts.
- Validating AI-generated patches against existing production codebases to catch unintended side effects.
- Explaining technical changes to non-technical stakeholders who need a clear visual representation of updates.
- Iterating on code snippets during collaborative debugging sessions to quickly spot syntax errors or logic flaws.
Key capabilities
- Renders formatted diff blocks with clear visual indicators for added and removed lines.
- Provides an intuitive, inline view of file changes without requiring external tools.
- Supports detailed context display around modified code sections.
Example prompts
- "Show me a side-by-side diff of the updated authentication module compared to the original version."
- "Generate a visual comparison of my new feature implementation against the legacy code structure."
- "Display the changes made in this file as a formatted diff so I can review the specific line modifications."
Tips & gotchas
Ensure your source code is properly formatted before requesting a diff to avoid rendering artifacts. For large files, consider asking the agent to focus on specific functions or sections to keep the preview readable and relevant.
