Config Location

The CLI automatically finds your Claude config at:

• Windows: %APPDATA%\claude\config.json
• macOS: ~/Library/Application Support/claude/config.json
• Linux: ~/.config/claude/config.json

📦 What Gets Installed

Global NPM Packages

1. @fast-kit/spec-kit

   • Specification management MCP server
   • PRD, RFC, ADR, User Stories, API Specs

2. @fast-kit/prompt-kit

   • 23 production-ready prompts
   • Code generation, testing, debugging, refactoring

Claude Configuration

Adds to config.json:

{
  "mcpServers": {
    "spec-kit": {
      "command": "node",
      "args": ["/path/to/global/node_modules/@fast-kit/spec-kit/dist/index.js"]
    },
    "prompt-kit": {
      "command": "node",
      "args": ["/path/to/global/node_modules/@fast-kit/prompt-kit/dist/index.js"]
    }
  }
}

🐛 Troubleshooting

"Command not found: fast-kit"

Solution: Make sure npm global bin is in your PATH

# Check npm global bin location
npm bin -g

# Add to PATH (example)
# Windows: Add to System Environment Variables
# macOS/Linux: Add to ~/.bashrc or ~/.zshrc
export PATH="$(npm bin -g):$PATH"

"Servers not showing in Claude Code"

Solution:

# 1. Validate installation
fast-kit validate --verbose

# 2. Check what's installed
fast-kit list

# 3. Restart Claude Code completely (quit and reopen)

# 4. If still not working, re-run setup
fast-kit setup --verbose

"Permission denied" (macOS/Linux)

Solution: Use sudo for global install

sudo npm install -g @fast-kit/cli
sudo fast-kit setup

Or configure npm to install globally without sudo:

mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

# Now install without sudo
npm install -g @fast-kit/cli
