  SLayer ships a zero-config demo dataset (the dbt "Jaffle Shop" sample, generated
  locally via jafgen + DuckDB) so the MCP server, CLI, and queries work end-to-end
  after a single install with no external database. This is the provider's published
  test/sandbox surface; no synthetic test values are invented here.
demo:
  name: Jaffle Shop (dbt sample)
  engine: DuckDB (bundled) + jafgen data generator (core dependencies)
  zero_config: true
  setup:
  - description: Add SLayer with the demo dataset preloaded to Claude Code (stdio MCP).
    command: claude mcp add slayer_demo -- slayer mcp --demo
  - description: Create the demo datasource explicitly.
    command: slayer datasources create demo
  models: [orders, customers, ...]
  note: >-
    `slayer mcp --demo` preloads the Jaffle Shop demo on startup; SQLite and MCP
    also work out of the box with the base install.
live_vs_test:
  note: >-
    For real data, create a datasource pointing at your own database
    (`slayer datasources create 'postgresql://user:${DB_PASSWORD}@host/db'`); the
    password is read at init time, not written to disk nor exposed to the agent.
