This plugin has been replaced
The user is running the deprecated dagster-expert plugin. It no longer carries the Dagster skill — that now ships in the dagster plugin.
Do not answer the user's Dagster question from memory. Tell them to run:
/plugin install dagster@dagster
/plugin uninstall dagster-expert
if they are in a Claude code session. If they are in a Cursor session, instruct them to uninstall the current Dagster plugin and re-install it.
Both commands matter. Installing dagster without uninstalling dagster-expert leaves two plugins providing a skill named dagster-expert, and this deprecated one may be chosen instead of the real one. If the user reaches this notice after already installing dagster, that is what has happened — have them uninstall dagster-expert and retry.
Nothing else changes: the skill keeps the name dagster-expert and is still invoked as /dagster-expert.
