Development Skills

Project-specific development patterns and workflows are in .claude/skills/:

• documentation - Documentation standards (thin AGENTS.md philosophy, TSDoc strategy, README.md tone)
• mcp-patterns - MCP server patterns (Zod schemas, error handling, logging, response format)
• ai-sdk-patterns - Vercel AI SDK patterns (input schemas, API key handling, response format)
• teams-anthropic-patterns - Teams.ai patterns (Memory API, Anthropic SDK, MCP client setup)

These skills are used by AI coding assistants when contributing to dx-toolkit packages. View development guide →

Quick Start

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
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

Troubleshooting tests: If you get API key errors when running tests:

1. Verify .env file exists with YDC_API_KEY=your-key
2. Run source .env to load environment variables
3. Try running tests again: bun test

For comprehensive development guidelines, see AGENTS.md.

Monorepo Commands

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

Workspace-Level Commands

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

Package-Specific Commands

From Root - Two patterns available:

# Pattern 1: Root shortcuts (defined in root package.json)
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

# Pattern 2: Direct package commands with bun --cwd
bun --cwd packages/mcp dev      # Start MCP server in dev mode
bun --cwd packages/mcp start    # Start MCP server in HTTP mode
bun --cwd packages/mcp test     # Test MCP server
bun --cwd packages/mcp check    # Run quality checks

# Use bun --cwd for any package script:
bun --cwd packages/api test
bun --cwd packages/ai-sdk-plugin build
bun --cwd packages/teams-anthropic check

From Package Directory:

cd packages/mcp
bun dev                  # Start in development mode
bun test                 # Run tests
bun run check            # Check code quality
