See CONTRIBUTING.md for guidelines and AGENTS.md for project-specific rules.

Development

npm install          # Install all dependencies
npm run build        # Build all packages
npm run check        # Lint, format, and type check
./test.sh            # Run tests (skips LLM-dependent tests without API keys)
./pi-test.sh         # Run pi from sources (must be run from repo root)

Note: npm run check requires npm run build to be run first. The web-ui package uses tsc which needs compiled .d.ts files from dependencies.
