Prueba QueryData en Studio
En esta sección, usa el conjunto de contexto de flights-assistant haciendo preguntas en lenguaje natural para generar una consulta en SQL.
Dado que el conjunto de contexto no tiene ningún archivo de conjunto de contexto subido y
los esquemas de Bigtable solo exponen nombres de familia de columnas (info) en lugar
de calificadores de columnas individuales, QueryData adivina los calificadores de columnas y
genera consultas subóptimas.
- En el panel Explorador, junto a tu conjunto de contexto, haz clic en Ver acciones ().
- Haz clic en Probar conjunto de contextos.
- En el editor de consultas, haz clic en Generar SQL con QueryData con: flights-assistant.
Ingresa la siguiente pregunta en lenguaje natural para generar una consulta en SQL y haz clic en Generar.
Find flights from SFO to JFK.Revisa la consulta en SQL. Sin un conjunto de contexto, QueryData ve la familia de columnas info (
MAP<BYTES, BYTES>) en la tabla flights, pero no los calificadores de columnadeparture_airportyarrival_airport, por lo que adivina nombres de calificadores comooriginydestination:SELECT _key, info FROM flights WHERE CAST(info['origin'] AS STRING) = 'SFO' AND CAST(info['destination'] AS STRING) = 'JFK';En la ventana Generar SQL con QueryData con: flights-assistant, haz clic en Editar.
Ingresa la siguiente pregunta en lenguaje natural para generar una consulta en SQL y haz clic en Actualizar.

Genera contexto para el conjunto de contextos
En esta sección, prepararás el entorno y crearás un archivo de contexto que ayude a mejorar las capacidades de consulta del conjunto de contexto.
Configura tu entorno
Antes de comenzar a generar contexto, debes preparar tu entorno.
Para configurar tu entorno, sigue estos pasos:
- Instala la CLI de Antigravity. Para obtener más información, consulta Comienza a usar la CLI de Antigravity.
- Instala Google Cloud CLI.
Configura las credenciales predeterminadas de la aplicación (ADC). Ejecuta los siguientes comandos en la terminal para autenticarte y seleccionar tu proyecto:
gcloud auth application-default loginInstala
uv, un administrador de paquetes y proyectos de Python que es un requisito previo para el agente de ingeniería de contexto. Si aún no tienes Python en tu sistema,uvpuede instalarlo por ti.Instala el agente de ingeniería de contexto:
agy plugin install https://github.com/GoogleCloudPlatform/db-context-enrichment/tree/main/pluginEn la terminal, inicia la CLI de Antigravity.
agyConfigurar una conexión de base de datos para la generación de contexto con MCP Toolbox La conexión se define en el archivo de configuración
tools.yaml.Para crear el archivo de configuración
tools.yamlen tu directorio actual, ingresa una instrucción como la siguiente:Help me set up a database connection.Sigue las instrucciones que se proporcionan en la skill. Para obtener más información sobre el archivo
tools.yaml, consulta la documentación de MCP Toolbox.Para volver a cargar la configuración después de crear el archivo
tools.yaml, ejecuta el siguiente comando en la CLI de Antigravity y sigue las instrucciones para volver a cargar el servidor de MCP de la caja de herramientas:/mcpSelecciona
db-context-engineering_toolbox.Selecciona
Restart.
Verifica que la caja de herramientas de MCP y el complemento del agente de ingeniería de contexto estén conectados y listos para usarse.

Genera el contexto de la plantilla
En esta sección, para abordar el problema de la sección anterior en la que
QueryData no conocía los calificadores de columna flights ni el término nighttime
traffic, define plantillas en el archivo de conjunto de contexto que asignen preguntas en lenguaje natural
a los calificadores de la familia de columnas de información y define nighttime traffic como
el tráfico que se produce entre las 5:00 p.m. y las 7:00 p.m.
Para generar el contexto de la plantilla, sigue estos pasos:

Genera el contexto de búsqueda de valores
En esta sección, generarás un contexto de búsqueda de valores para ayudar a que la lógica de configuración del contexto asigne
frases de valor a valores específicos almacenados en tus columnas de Bigtable
con una coincidencia de cadena exacta que no distinga mayúsculas de minúsculas. Por ejemplo, si un usuario solicita
vuelos a "Raleigh-Durham", la búsqueda de valores asigna esto al valor de la base de datos almacenada
"Raleigh-durham" (código de aeropuerto RDU).
Para generar el contexto de búsqueda de valores, sigue estos pasos:
Ingresa la siguiente instrucción en el arnés del agente.
Generate a case-insensitive value search on table "airports" for column "info['city']" with concept "Airport City" using match function "EXACT_MATCH_STRINGS".Revisa la definición de búsqueda de valores generada.

Usa el agente de ingeniería de contexto para generar contexto y, luego, sube el archivo de conjunto de información contextual actualizado al agente de datos flights-assistant existente. Para obtener más información, consulta Administra conjuntos de contexto en Bigtable Studio. La consola transfiere de inmediato el contexto nuevo después de que lo subes, lo que te permite mejorar la precisión del agente sin tiempo de inactividad de la aplicación.
Varios agentes
En tu entorno de desarrollo, puedes realizar pruebas A/B en varios contextos de agentes de datos asignando nombres distintos a las herramientas en tu archivo tools.yaml. Por ejemplo, puedes crear configuraciones de tools.yaml únicas definiendo dos herramientas de cloud-gemini-data-analytics-query con nombres diferentes, como cloud_gda_query_tool_v1 y cloud_gda_query_tool_v2. Esta configuración te permite implementar la lógica de la aplicación que selecciona de forma programática la versión de contexto requerida eligiendo el nombre de la herramienta correspondiente.
En el siguiente ejemplo de tools.yaml, se muestra cómo configurar varios agentes de datos para una fuente de base de datos:
kind: source
name: gda-api-source
type: cloud-gemini-data-analytics
