+# 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 development environment setup repository containing:
+- Shell scripts for automated installation of development tools
+- Dotfiles for bash, vim, tmux, git, psql, and pspg
+- The main `setup_env.sh` script deploys dotfiles as symlinks and installs base packages
+
+## Key Commands
+
+### Environment Setup
+```bash
+# Initial setup - installs packages, plugin managers, and creates symlinks
+./setup_env.sh
+
+# Individual tool installations
+./install_postgres.sh      # PostgreSQL from official repository
+./install_python3.sh       # Latest Python 3 from deadsnakes PPA
+./install_java_dev.sh      # SDKMAN for Java development
+./install_neovim.sh        # Latest Neovim release
+./install_visidata.sh      # VisiData for terminal data exploration
+```
+
+### Git Operations
+```bash
+# Automated commit and push (defined in .bashrc)
+vc                         # git add . && commit with timestamp && push
+
+# Custom git aliases (defined in .gitconfig)
+git pushall                # Push to all remotes
+```
+
+## Architecture
+
+### Dotfile Management System
+The repository uses **symlink-based configuration deployment**. When `setup_env.sh` runs:
+1. Each dotfile in `dotfiles/` is backed up if it exists (to `.backup`)
+2. A symlink is created from `~/.<filename>` to the repository's `dotfiles/.<filename>`
+3. This allows version control of configs while keeping them in their expected locations
+
+**Critical Files:**
+- `dotfiles/.bashrc` - Main bash configuration with extensive aliases and functions
+- `dotfiles/.bashrc_local` - Machine-specific environment variables (PG, MS connection strings)
+- `dotfiles/.bashrc_local_example` - Template for setting up machine-specific configs
+- `dotfiles/.vimrc` - Vim configuration using Vundle plugin manager
+- `dotfiles/.tmux.conf` - Tmux configuration with vim-style pane navigation
+- `dotfiles/.gitconfig` - Git configuration with custom log format and vimdiff
+- `dotfiles/.psqlrc` - PostgreSQL client configuration
+- `dotfiles/.pspgconf` - pspg (PostgreSQL pager) configuration
+
+### Custom Bash Workflow
+
+The `.bashrc` contains a sophisticated workflow for working with:
+
+**Database Query Management:**
+
+PostgreSQL workflow:
+- `xnspa()` function - Interactive file selector for running PostgreSQL queries through nvim swap files, outputs to VisiData as CSV
+- `xnsp` - Select and execute SQL file through fzf with pspg output
+- `xns` - Select and execute SQL file through fzf
+- `PG` environment variable - psql connection string to database (defined in `.bashrc_local`)
+
+SQL Server workflow:
+- `xmspa()` function - Interactive file selector for SQL Server queries through nvim swap files, outputs to VisiData with pipe-delimited format
+- `xmsp` - Select SQL file via fzf, execute with sqlcmd, pipe to pspg
+- `xms` - Select SQL file via fzf, execute with sqlcmd
+- `MS` environment variable - sqlcmd connection string to SQL Server (defined in `.bashrc_local`)
+- `MSC` environment variable - sqlcmd connection string with pipe-delimited output format (defined in `.bashrc_local`)
+- `MSW` environment variable - Windows sqlcmd connection (optional, defined in `.bashrc_local`)
+
+General:
+- `ons` - List open nvim files in current directory tree
+
+**Git workflow aliases:**
+- `gs` - git status short format
+- `ga` - Interactive git add using fzf for file selection
+- `gx` - Interactive git checkout using fzf
+- `gr` - git reset HEAD
+- `gc` - git commit verbose
+- `gd` - git difftool
+- `gl` - Pretty git log with colors
+
+**Todo tracking:**
+- `td` - Find unchecked todo items using ripgrep
+- `tdp` - Find priority todos (with 🔼 or ⏫)
+- `tdtp` - Find top priority todos (⏫ only)
+- `tdo` - Open todo in nvim at exact line
+- `tdop` - Open priority todo in nvim at exact line
+
+**Other useful aliases:**
+- `nv` - Launch Neovim from custom installation path
+- `cj` - Navigate to journal directory
+- `jr` - Journal sync (pull, commit, push)
+- `hc` - Health/care notes sync (pull, push)
+
+### Plugin Managers
+- **Vim**: Vundle (installed to `~/.vim/bundle/Vundle.vim`)
+- **Tmux**: TPM - Tmux Plugin Manager (installed to `~/.tmux/plugins/tpm`)
+  - Plugins: tmux-resurrect, jimeh/tmux-themepack
+- **Bash**: bash-git-prompt (installed to `~/.bash-git-prompt`)
+
+### Package Dependencies
+Base packages installed by `setup_env.sh`:
+- tmux, vim, git, pspg, bat, fzf, ripgrep
+
+## Important Conventions
+
+### Environment Variables
+Machine-specific environment variables (database connections, tokens, passwords) belong in `dotfiles/.bashrc_local`, not `.bashrc`. This file is sourced by `.bashrc` and should contain sensitive or machine-specific configuration.
+
+The `.bashrc_local` file is gitignored for security. Use `dotfiles/.bashrc_local_example` as a template when setting up a new machine. Copy it to `.bashrc_local` and fill in your actual credentials.
+
+### Symlink Pattern
+When modifying dotfiles, remember they are symlinked. Changes are automatically tracked by git since the actual files are in the repository's `dotfiles/` directory.
+
+### Git Commit Messages
+Based on recent commits, this repository uses simple lowercase commit messages describing the change (e.g., "add cargo", "visidata", "install sdkman").
