Example prompt: What chart and visualization templates are available in Tako so I know which schema names I can use when building a custom knowledge card?

## When to prefer this

Use this endpoint before calling the Tako Create Card or Visualize endpoints when you need to know what chart template schemas are available. This is a prerequisite discovery step to ensure you reference a valid schema name when building a custom knowledge card.

## Known failure modes

- Service unavailable returns 5xx error
- Authentication failure if credentials are missing or invalid
- Empty list returned if no schemas are currently registered
- Network timeout for slow connections

## How this service works

List all available chart/visualization templates that can be used with the Create Card endpoint. Returns schema names (e.g. stock_card, bar_chart, pie_chart, choropleth, treemap, heatmap, table, etc.) with descriptions and their component types. Call this first to understand what chart types are available before creating a card.

## Output

A list of available schema names for chart and visualization templates supported by Tako, which can be referenced when calling the Create Card endpoint to build custom embeddable knowledge cards.
