What Semantic Layer Capture does

Semantic Layer Capture defines when and how to capture new reusable patterns into ktx's semantic layer—measures, segments, computed dimensions, and joins—so future queries can reuse them instead of rediscovering logic. Use it after a turn produces a reusable business metric or analytical view.

Semantic Layer Capture is cataloged under Data on DirSkills. Semantic Layer Capture comes from a repository tagged agent, agent-skills, agents, ai-agent and ai-agents.

Excerpt

Semantic Layer - Capture

This skill covers when and how to capture new patterns into the semantic layer. For schema reference and query grammar, load the sl skill first.

When the current turn produces a reusable pattern (business metric, derived view, join pattern, computed dimension), capture it so future queries can reach for it instead of rediscovering it.

SQL dialect

The user-facing prompt includes a Warehouse: line under the SL Sources index (e.g. Warehouse: BIGQUERY). All expr strings - measure expressions, segment predicates, computed-column SQL - execute on that warehouse and must use its syntax. Date arithmetic in particular varies by dialect:
