dagster-expert
The reference desk for Dagster, the tool teams use to build data pipelines: what each piece of it is called, which command does what, and how the parts fit together.
LABSCO SUMMARY
Summary
Dagster's own skills repo now ships one skill, dagster-expert, the Dagster guide; dignified-python, the general Python-style skill its README still describes, is no longer in the repository.
dagster-expert, which expects the dg CLI already set up, is the Dagster guide: scaffolding new projects, assets, schedules, and sensors, wiring declarative automation, running dg CLI commands like launch, list, check, and scaffold, and debugging failed materializations, per the README's own example-prompt list.
The repository has shed skills, not gained them.
Earlier skills used to ship here — dagster-best-practices, dagster-conventions, dagster-integrations, integrations-index, dg, dignified-python, and prior versions of dagster-expert — and none of them ships today; the README doesn't say whether that reflects a deliberate consolidation into today's one skill or an abandoned earlier structure.
