Claude Code + Neovim Integration - Product Requirements Document

1. Executive Summary

Problem Statement

Claude Code operates independently of text editors, making file changes that users need to manually track and review. When using Neovim as the primary editor, developers miss real-time visibility of Claude Code's modifications, leading to workflow friction and potential confusion about what changes are being made.

Solution

A bidirectional integration system that bridges Claude Code and Neovim, providing real-time file change synchronization, diff previews, and interactive change acceptance/rejection capabilities.

2. Goals & Objectives

Primary Goals

  • Real-time Sync: Instantly reflect Claude Code's file modifications in Neovim
  • Change Visibility: Show pending changes before they're written to disk
  • User Control: Allow accepting/rejecting changes from within Neovim
  • Workflow Integration: Seamless integration without disrupting existing workflows

Success Metrics

  • < 100ms latency between Claude Code action and Neovim notification
  • Zero data loss during synchronization
  • Support for multiple simultaneous file changes
  • Works with existing Neovim configurations without conflicts

3. User Stories

As a Developer

  1. I want to see Claude Code's proposed changes in my Neovim buffer so that I can review them before they're applied
  2. I want to accept or reject changes individually so that I maintain control over my codebase
  3. I want to see a diff view of changes so that I understand what's being modified
  4. I want to have syntax highlighting preserved so that changes are easy to read
  5. I want to continue using Neovim normally so that my workflow isn't disrupted

As a Power User

  1. I want to configure which files are auto-reloaded so that I can customize the behavior
  2. I want to see change history so that I can track what Claude Code has done
  3. I want to trigger Claude Code actions from Neovim so that I never leave my editor

4. Functional Requirements

Core Features

4.1 File Change Detection

  • Monitor file system for changes made by Claude Code
  • Detect create, update, delete operations
  • Track changes at line-level granularity
  • Support for multiple file types and encodings

4.2 Neovim Integration

  • Native Neovim plugin (Lua-based)
  • Automatic buffer refresh on external changes
  • Preserve cursor position and view
  • Maintain undo history where possible

4.3 Change Preview System

  • Floating window for diff preview
  • Side-by-side comparison view option
  • Inline change indicators
  • Syntax highlighting in diffs

4.4 Interactive Controls

  • Keybindings for accept/reject changes
  • Partial acceptance (line-by-line or hunk-by-hunk)
  • Bulk operations for multiple files
  • Undo/redo support for accepted changes

4.5 Notification System

  • Visual indicators for pending changes
  • Status line integration
  • Notification popups for new changes
  • Sound/system notifications (optional)

Advanced Features

4.6 Claude Code Integration

  • Intercept Claude Code's file operations
  • Preview mode before writing to disk
  • Command palette for Claude Code actions
  • Context sharing (current file, selection)

4.7 Diff Management

  • Persistent diff history
  • Diff queue for multiple pending changes
  • Three-way merge for conflicts
  • Git integration for version control awareness

5. Non-Functional Requirements

Performance

  • Latency: < 100ms for change detection
  • Memory: < 50MB additional memory usage
  • CPU: < 5% CPU usage during monitoring
  • Scalability: Handle 100+ file changes per minute

Reliability

  • Availability: 99.9% uptime during development sessions
  • Recovery: Automatic reconnection after disconnection
  • Data Integrity: No file corruption or data loss
  • Fault Tolerance: Graceful degradation on errors

Usability

  • Installation: Single command installation
  • Configuration: Sensible defaults, optional customization
  • Documentation: Comprehensive help within Neovim
  • Learning Curve: < 5 minutes to start using

Compatibility

  • Neovim Versions: 0.8.0+
  • Operating Systems: Linux, macOS, Windows (WSL)
  • Claude Code Versions: Latest stable release
  • File Systems: Local and network filesystems

6. Technical Constraints

Dependencies

  • Neovim 0.8+ (for Lua 5.1+ support)
  • File system watching capability (inotify/fsevents/etc.)
  • IPC mechanism (Unix sockets/named pipes)
  • Optional: tmux for session management

Limitations

  • Binary file changes not previewed (notification only)
  • Large file changes (>10MB) may have delayed preview
  • Some Neovim plugins may conflict with auto-reload

7. User Interface
