Our review of Dagster Compass agent
Dagster Compass is very quick to set up: you connect tables, add it to Slack, and let it scan and sample your data. The context is intentionally light (metadata, sampling, and a system prompt) and, without dbt docs, it misunderstood our benchmark use case. The experience is a Slack bot with static charts and no standalone UI or SQL transparency, but having context versioned in Git is a nice governance touch.
