Development

Branch strategy

feature-branch -> PR to dev -> verify on dev -> PR to main -> deploy

Never push directly to main. main triggers npm publish and Vercel deployment.

Setup

git clone https://github.com/Ansvar-Systems/german-standards-mcp.git
cd german-standards-mcp
npm install
npm run build
npm test

Ingestion

# Build the database from extracted JSON files
npm run build:db

# Check freshness
npm run freshness:check

Pre-deploy verification

npm run build            # Gate 1: build
npm run lint             # Gate 2: TypeScript strict
npm test                 # Gate 3: unit tests
npm run test:contract    # Gate 4: golden contract tests
sqlite3 data/standards.db "PRAGMA integrity_check;"   # Gate 5: DB integrity
npm run coverage:verify  # Gate 6: coverage consistency
