Looker
Map Looker explores, views, and derived tables to the models and warehouse objects they depend on.
Semantic Layers & BIWhy Looker matters
LookML encodes business logic that AI agents and analysts depend on: dimension definitions, derived table SQL, and explore joins. When those definitions drift from the underlying data, agents confidently return wrong answers and dashboards silently degrade.
Typedef parses LookML and connects every definition to its upstream sources and downstream consumers, including AI agents, so you can catch inconsistencies before they propagate and trace the full impact of any change through the BI layer.
What Typedef unlocks
LookML-aware impact analysis
See which explores, dashboards, and AI agents break when a warehouse column is renamed or a derived table is restructured.
Semantic drift detection
Detect when LookML definitions fall out of sync with upstream schema changes or business logic updates before consumers notice.
Agent dependency tracing
Know which AI agents rely on specific Looker dimensions and measures, so definition changes are validated against agentic consumers, not just dashboards.
Cross-tool definition reconciliation
Surface where LookML definitions align with or contradict definitions in other semantic layers and BI tools, closing gaps that lead to conflicting answers.
