Presets

• plugin:@miragon/rules/recommended-for-modeling — for purely business/technical models, and for modeler applications that surface linting to their users. Layout hints only: bpmnlint's standard-size and the layout rules at warn, the naming/id rules off — a modeler is never blocked on execution-only conventions.
• plugin:@miragon/rules/recommended-for-automation — for developers automating processes, locally and in CI, on models wired up to a Camunda engine. Every Miragon rule on but as a non-blocking warn (standard-size too), so ids and layout get flagged without failing the build.
• plugin:@miragon/rules/all — every Miragon rule at error, engine-agnostic. The strict gate to opt into when you want findings to fail the build.

Only all reports at error, so only all can fail a build on a Miragon finding. Override any single rule in your own config:

// .bpmnlintrc
{
  "extends": [
    "bpmnlint:recommended", // structural rules
    "plugin:@miragon/rules/recommended-for-modeling", // your preset
  ],
  "rules": {
    "@miragon/rules/no-generated-ids": "error", // raise one rule
    "@miragon/rules/flow-crossing": "off", // silence another
  },
}
