+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Repository Overview
+
+This is a personal dotfiles repository containing configuration files for a macOS development environment. The setup includes:
+
+- **Neovim** - Custom configuration with lua-based architecture and lazy.nvim plugin management
+- **Zsh** with oh-my-zsh and antigen - Shell configuration with vi-mode and extensive development tooling
+- **Tmux** - Terminal multiplexer with custom key bindings and theming
+- **WezTerm** - GPU-accelerated terminal emulator with Tokyo Night theme
+- **Starship** - Cross-shell prompt with vim mode indicators and development context
+- **Git** - Comprehensive configuration with SSH signing via 1Password and custom aliases
+
+## Common Commands and Workflows
+
+### Environment Setup
+```bash
+# Install all dependencies and link dotfiles
+./setup.sh recover
+
+# Install packages via Homebrew
+brew bundle install
+
+# Update Neovim plugins
+nvim +Lazy update
+
+# Reload zsh configuration
+source ~/.zshrc
+
+# Update shell plugins
+antigen reset && antigen apply
+```
+
+### Development Workflows
+```bash
+# Interactive tmux session management
+m                                    # Launch tmux session picker with fzf
+
+# Git operations with custom functions
+git_clean main                       # Clean merged branches based on main
+git_config_work "name" "email"       # Configure git for work environment
+git_config_play "email"              # Configure git for personal projects
+replace_remote work                  # Switch git remote to work configuration
+
+# Kubernetes utilities
+klogs <keyword>                      # Get logs from most recent pod matching keyword
+bitnami_seal <namespace> <file>      # Seal secrets with kubeseal
+
+# Remote development sync
+rsync_work [server_number] [back]    # Sync local work to remote development servers
+```
+
+### Key Aliases
+```bash
+# Terminal and file management
+ls -> lsd                           # Modern ls replacement
+vi -> nvim                          # Neovim as default editor
+pn -> pnpm                          # Package manager preference
+
+# Git shortcuts (from git config)
+git st -> git status
+git co -> git checkout
+git cb -> git checkout -b
+git cm -> git commit -s -m
+git ca -> git commit --amend -s --no-edit
+
+# Kubernetes shortcuts
+kctx -> kubectx                     # Context switching
+kns -> kubens                       # Namespace switching
+kget -> kubectl get
+kdesc -> kubectl describe
+```
+
+## Configuration Architecture
+
+### Shell Environment (.zshrc)
+- **Package Management**: Antigen for zsh plugin management with oh-my-zsh base
+- **Vi-mode**: Enabled with custom key bindings and starship prompt indicators
+- **Development Paths**: Configured for Go, Rust, Node.js, Python, and Kubernetes tooling
+- **Custom Functions**: Includes utilities for git operations, Kubernetes management, and remote syncing
+
+### Neovim Configuration (nvim/)
+- **Plugin Manager**: lazy.nvim with performance optimizations and lazy loading
+- **Architecture**: Modular lua-based configuration with core/ and plugins/ directories
+- **Language Support**: Go, Python, Rust, and general development plugins
+- **Theme**: Tokyo Night colorscheme with custom UI configuration
+
+### Terminal Setup
+- **WezTerm**: Primary terminal with vim-like keybindings and Tokyo Night theme
+- **Tmux**: Available with custom prefix (C-a) and vim-like navigation
+- **Font**: JetBrains Mono Nerd Font with Maple Mono CN fallback
+
+### Multi-Environment Git Support
+The configuration supports multiple git identities through functions:
+- `git_config_work()` - Configure work environment with work signing key
+- `git_config_play()` - Configure personal environment with personal signing key
+- `replace_remote()` - Switch between ops/work/play git remote configurations
+- SSH signing integration with 1Password for secure commit signing
+
+### Kubernetes Development
+- Extensive kubectl aliases and custom functions for container-first development
+- Context switching with kubectx/kubens
+- Log monitoring with `klogs()` function
+- Secret sealing with `bitnami_seal()` for GitOps workflows
+
+## Performance Optimizations
+
+### Neovim
+- Disabled unnecessary built-in plugins (gzip, netrw, etc.)
+- Lazy loading for non-essential plugins
+- Treesitter for syntax highlighting and navigation
+
+### Shell
+- Antigen for efficient plugin management
+- Starship for fast prompt rendering
+- FZF integration for fuzzy finding
+- Direnv for directory-based environment management
+
+### Terminal
+- WezTerm with GPU acceleration
+- Tmux with optimized key bindings
+- Custom aliases for common operations
+
+## Development Tools Integration
+
+### 1Password Integration
+- SSH agent configured for commit signing
+- Git signing key management through 1Password SSH agent
+
+### Package Managers
+- Homebrew for macOS packages and applications
+- pnpm preferred over npm for Node.js projects
+- Rust via rustup with clippy component
+
+### Language Tooling
+- Go development with proper GOPATH configuration
+- Python with pip3 and virtual environment support
+- Rust with cargo and rustup integration
+- Node.js with pnpm and proper PATH configuration
