Cc Split Diff View — Development skill for Claude Code

Split diff view for Claude Code

A [Claude Code mod](https://code.claude.com/docs/en/plugins/mods/overview) that draws the diff of every `Edit` and `Write` in **two side-by-side columns** instead of one stacked `-`/`+` list:

• removed lines on the left, added lines on the right
• each side keeps its real line numbers
• a changed line sits next to the line that replaced it
• long runs between hunks collapse to ⋯ N unchanged lines
• colors are Claude Code's own diff colors (diffRemoved / diffAdded theme keys), so they follow your /theme
• syntax highlighting comes from Claude Code's own highlighter (the Code element, the one the built-in /diff pane uses), with the language taken from the file's extension

Errors, edits held for review, brand-new files and anything without a diff keep Claude Code's normal drawing.

Requirements

• Claude Code v2.1.287 or later (the version that introduced mods; they are on by default). Check with claude --version.
• Mods must be allowed to load: not started with --safe-mode or --bare, and not blocked by your organization's managed settings.

Install

From a terminal:

claude plugin marketplace add neteye-platform/cc-split-diff-view
claude plugin install cc-split-diff-view@neteye-platform

Or from inside a Claude Code session:

/plugin marketplace add neteye-platform/cc-split-diff-view
/plugin install cc-split-diff-view@neteye-platform

No download or build step is needed: Claude Code fetches the repository and loads the TypeScript directly. Start a new session (or run `/reload-plugins`), then ask Claude to edit a file.

To check it loaded, run `/plugin` and look for `cc-split-diff-view` under **Installed**.

Update

Claude Code caches an installed plugin by version, so updates arrive when the `version` in `.claude-plugin/plugin.json` is bumped:

claude plugin marketplace update neteye-platform

Uninstall

claude plugin uninstall cc-split-
