Adds side-by-side diff preview when Claude proposes file edits (Edit, Write, MultiEdit). Uses Claude Code PreToolUse/PostToolUse hooks to intercept changes and display a diff tab in Vim before accepting. New commands: - :Claude preview install — register hooks in .claude/settings.local.json - :Claude preview uninstall — remove hooks - :Claude preview close — manually close diff tab - :Claude preview status — show status and dependency checks New files: - autoload/claude_code/diff.vim — diff display, polling, hook management - bin/vim-preview-diff.sh — PreToolUse hook script - bin/vim-close-diff.sh — PostToolUse hook script - bin/apply-proposed.py — compute proposed file content Requires python3 and jq. Supports both file-based polling (universal) and vim --servername (instant, when +clientserver available). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…ect keybindings - Fix s:bin_dir() using <sfile> inside function (returns call stack, not file path) - Strip trailing slash from $TMPDIR on macOS to avoid double-slash paths - Skip stale trigger files when temp files no longer exist - Add ga/gr keybindings in diff buffer to accept/reject changes Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add documentation for the new diff preview commands, requirements, configuration, and plugin structure changes introduced in ba1ecc9. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

This PR introduces the Visual Diff Preview feature to safely review Claude Code file modifications in a native Vim side-by-side buffer. It resolves #18.
Credits & Implementation
This is a collaborative effort:
.claude/settings.local.jsoninjection strategy to hijack thePreToolUsehooks, authored the deep Vimscript window management logic (autoload/claude_code/diff.vim), the sub-command dispatcher routing (plugin/claude_code.vim), and the IPC fallback mechanisms.jqdependencies into standard-library Python scripts, modified.replace()to handleMultiEditcode blocks safely, and sandboxed the IPC temp files securely inside the repo's.claude/tmp/directory to prevent/tmpmulti-user concurrency race conditions.By merging this, we solve the 'blind-trust' edit problem while keeping the plugin lightweight and secure!
