Prerequisites:

• Bun >= 1.2.21: Installation guide
• GitHub CLI (recommended): brew install gh (macOS) or other platforms

Development setup:

# Clone repository
git clone git@github.com:youdotcom-oss/dx-toolkit.git
cd dx-toolkit

# Install dependencies
bun install

# Set up environment variables
cp .env.example .env
# Edit .env and add your YDC_API_KEY and ANTHROPIC_API_KEY
source .env

# Authenticate with GitHub (if using gh CLI)
gh auth login

# Build all packages
bun run build

# Run all tests
bun test

# Run all quality checks
bun run check

For comprehensive development guidelines, see AGENTS.md.

This toolkit uses Bun workspaces. Commands can run at workspace-level (all packages) or package-level (specific package).

Run from repository root to affect all packages:

bun install              # Install dependencies for all packages
bun run build            # Build all packages
bun test                 # Test all packages
bun run check            # Run all quality checks (biome + types + package)
bun run check:write      # Auto-fix all issues across all packages

From Root (run specific package commands):

# MCP Server (using root shortcuts)
bun run dev:mcp          # Start MCP server in STDIO mode
bun run start:mcp        # Start MCP server in HTTP mode
bun run test:mcp         # Test MCP server only

# Or call package scripts directly:
bun --cwd packages/mcp dev
bun --cwd packages/mcp start
bun --cwd packages/mcp test

# All packages follow this pattern:
# bun run <command>:<package>
# bun --cwd packages/<package> <command>
