  "check": {
    "kind": "command",
    "value": "node --check src/main.js"
  },
  "budget": {
    "tokens": 12000,
    "turns": 12,
    "active_minutes": 30
  },
  "no_progress_limit": 3
}
~~~~

Rejected: missing-check-kind

~~~~
{
  "goal": "The file exists.",
  "check": {
    "value": "test -f src/main.js"
  }
}
~~~~

## Validate

~~~~
const contracts = require('openvibe-contracts');
