🚀 Quick Start

AI-assisted Setup

Tell Agent:

Fetch and follow instructions from https://raw.githubusercontent.com/shihyuho/dotfiles/refs/heads/main/docs/INSTALL.md

Manual Setup

DOTFILES_DIR="${DOTFILES_DIR:-$HOME/.config/dotfiles}"

# Clone repository
git clone https://github.com/shihyuho/dotfiles.git "$DOTFILES_DIR"
cd "$DOTFILES_DIR"

# Complete setup (symlinks + Homebrew packages)
make setup

# Or step by step:
make install  # Create symlinks only
make brew     # Install Homebrew packages only

# First-time setup: create local secrets file
cp "$DOTFILES_DIR/secrets.example" ~/.secrets
chmod 600 ~/.secrets
# Then edit ~/.secrets and set sensitive env vars

# Uninstall managed symlinks (optional)
make uninstall

# Restart shell
exec zsh

make install also manages Claude and OpenCode paths, including ~/.claude/settings.json and paths under ~/.config/opencode/, including opencode.json, oh-my-opencode-slim.json, commands/, agents/, oh-my-opencode-slim/. If those paths already exist, the installer moves them into ~/.dotfiles_backup/... before creating symlinks.

After installation, edit config/claude/settings.json in this repo, not ~/.claude/settings.json.

🛠️ Main Tools

📖 Documentation

• AGENTS.md: AI agent guide (architecture principles, modification rules)
• docs/INSTALL.md: AI installation playbook
• docs/SETUP.md: Human installation guide
• docs/TOOLS.md: Tool list and sources

🎯 Design Principles

1. Performance First: Startup speed < 0.5s

   • Use fast-path defaults for common Homebrew prefixes with fallback detection for non-standard installs
   • Smart caching (completion, git info)
   • Lazy loading for dev tools

2. Modular: Organized by functionality, easy to maintain

   • Core configs (zsh/core/): Loaded in numeric order
   • Tool configs (zsh/tools/): Conditional loading
   • Dev tools (zsh/tools/dev/): Lazy loading

3. AI-Friendly:

   • Detailed AGENTS.md included
   • Config files include metadata (source, purpose, update date)
   • Dedicated skill: .agents/skills/dotfiles-manager/ (project-level)

🔧 Maintenance

Adding New Tools

# 1. Edit Brewfile
echo 'brew "tool-name"' >> brew/Brewfile

# 2. Install
make brew

# 3. Check status
make check-tool TOOL=tool-name

# 4. Test
make test

Testing & Verification

# Run all tests
make test

# Run CI-friendly tests
make test-ci

# Detailed startup analysis
make measure-startup

# Check specific tool
make check-tool TOOL=kubectl
