 For an installed plugin, use `./plugins/stanp-opencode` as the plugin package path.

-Custom configurations require the six worker assignments and use `provider/model` model names.
+Custom configurations require the four `fast-*` and `good-*` assignments; `deep-lo` and `deep-hi` are optional. Assignments use `provider/model` model names and require both `model` and `effort` when supplied. If either deep assignment is omitted, both deep workers are disabled and orchestration uses `good-lo`.
 The legacy optional `coordinate` assignment is accepted for compatibility but ignored. Orchestration
 inherits `deep-lo`, or `good-lo` when the configured `deep-lo` model is unavailable.
