  4. Impor data dari file flights.csv ke tabel flights:

    cbt import flights flights.csv

  5. Di Bigtable Studio, jalankan kueri berikut untuk memverifikasi bahwa tabel telah diisi:

    • SELECT * FROM airports LIMIT 10;
       
    • SELECT * FROM flights LIMIT 10;

Membuat set data konteks di Bigtable Studio

Di bagian ini, buat set konteks bernama flights-assistant. Set konteks ini tidak menyertakan file set konteks yang diupload ke dalamnya.

  1. Di konsol Google Cloud , buka halaman Bigtable.

    Buka Bigtable

  2. Pilih instance dari daftar.

  3. Di menu navigasi, klik Bigtable Studio.

  4. Di panel Explorer, di samping Context sets, klik View actions ().

  5. Klik Create context set.

  6. Di Context set name, masukkan flights-assistant.

  7. Klik Create.

Menguji QueryData di Studio

Di bagian ini, gunakan set konteks flights-assistant dengan mengajukan pertanyaan dalam bahasa alami untuk membuat kueri SQL. Karena set konteks tidak memiliki file set konteks yang diupload ke dalamnya dan skema Bigtable hanya mengekspos nama grup kolom (info), bukan penentu kolom individual, QueryData menebak penentu kolom dan menghasilkan kueri yang kurang optimal.

  1. Di panel Explorer, di samping set konteks Anda, klik View actions ().
  2. Klik Test context set.
  3. Di editor kueri, klik Generate SQL using QueryData with: flights-assistant.

  4. Masukkan pertanyaan bahasa alami berikut untuk membuat kueri SQL, lalu klik Generate.

    Find flights from SFO to JFK.

    Tinjau kueri SQL. Tanpa set konteks, QueryData melihat grup kolom info (MAP<BYTES, BYTES>) di tabel penerbangan, tetapi tidak melihat penentu kolom departure_airport dan arrival_airport, sehingga menebak nama penentu seperti origin dan destination: 

      SELECT
    _key,
    info
  FROM
    flights
  WHERE
    CAST(info['origin'] AS STRING) = 'SFO'
    AND CAST(info['destination'] AS STRING) = 'JFK';

  5. Di jendela Generate SQL using QueryData with: flights-assistant, klik Edit.

  6. Masukkan pertanyaan bahasa alami berikut untuk membuat kueri SQL, lalu klik Update.

    Tell me flights that can help me beat nighttime traffic if traveling from New York

    Database gagal memahami istilah nighttime traffic dan menebak penentu kolom yang tidak ada dalam tabel flights seperti yang ditunjukkan oleh kueri berikut. 

    -- Assuming 'nighttime traffic' refers to flights departing during the night,
-- defined here as between 8:00 PM (20:00) and 5:00 AM (05:00).
SELECT
  CAST(_key AS STRING) AS flight_id,
  CAST(info['flight_number'] AS STRING) AS flight_number,
  CAST(info['origin'] AS STRING) AS origin,
  CAST(info['destination'] AS STRING) AS destination,
  CAST(info['departure_time'] AS STRING) AS departure_time
FROM
  flights
WHERE
  CAST(info['origin'] AS STRING) = 'New York'
  AND (
    EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) >= 20
    OR EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) < 5
  );

  7. Di jendela Generate SQL using QueryData with: flights-assistant, klik Edit.

  8. Masukkan pertanyaan bahasa alami berikut untuk membuat kueri SQL, lalu klik Update.

    Show me flights to Raleigh-Durham

    Tanpa konteks penelusuran nilai, QueryData menebak penentu kolom dan memfilter Raleigh-Durham. Karena tabel flights menyimpan kota sebagai Raleigh-durham di bagian info['arrival_city'], kueri tidak akan menampilkan baris apa pun.

    SELECT
  _key,
  info
FROM
  flights
WHERE
  CAST(info['destination_city'] AS STRING) = 'Raleigh-Durham';

Membuat konteks untuk set data konteks

Di bagian ini, Anda akan menyiapkan lingkungan dan membuat file konteks yang membantu meningkatkan kemampuan kueri set konteks.

Menyiapkan lingkungan Anda

Sebelum dapat mulai membuat konteks, Anda harus menyiapkan lingkungan Anda.

Untuk menyiapkan lingkungan Anda, lakukan langkah-langkah berikut:

  1. Instal Antigravity CLI. Untuk mengetahui informasi selengkapnya, lihat Memulai Antigravity CLI.
  2. Menginstal Google Cloud CLI.

  3. Siapkan Kredensial Default Aplikasi (ADC). Jalankan perintah berikut di terminal Anda untuk melakukan autentikasi dan memilih project Anda:

    gcloud auth application-default login

  4. Instal uv, paket Python dan pengelola project yang merupakan prasyarat untuk agen rekayasa konteks. Jika Anda belum memiliki Python di sistem, uv dapat menginstalnya untuk Anda.

  5. Menginstal agen rekayasa konteks:

    agy plugin install https://github.com/GoogleCloudPlatform/db-context-enrichment/tree/main/plugin

  6. Di terminal Anda, mulai Antigravity CLI.

    agy

  7. Menyiapkan koneksi database untuk pembuatan konteks menggunakan MCP Toolbox. Koneksi ditentukan dalam file konfigurasi tools.yaml.

    Untuk membuat file konfigurasi tools.yaml di direktori Anda saat ini, masukkan perintah seperti: 

    Help me set up a database connection.

    Ikuti petunjuk yang diberikan oleh skill. Untuk mengetahui informasi selengkapnya tentang file tools.yaml, lihat dokumentasi MCP Toolbox.

  8. Untuk memuat ulang konfigurasi setelah file tools.yaml dibuat, jalankan perintah berikut di Antigravity CLI dan ikuti petunjuk untuk memuat ulang server MCP toolbox:

    /mcp

    1. Pilih db-context-engineering_toolbox.

    2. Pilih Restart.

  9. Pastikan toolbox MCP dan plugin agen rekayasa konteks terhubung dan siap digunakan.

Membuat konteks template

Di bagian ini, untuk mengatasi masalah dari bagian sebelumnya, yaitu QueryData tidak mengetahui penentu kolom flights atau istilah nighttime traffic, tentukan template dalam file set konteks yang memetakan pertanyaan bahasa alami ke penentu grup kolom info dan tentukan nighttime traffic sebagai traffic yang terjadi antara pukul 17.00 dan 19.00.

Untuk membuat konteks template, lakukan langkah-langkah berikut:

  1. Masukkan perintah berikut ke Antigravity CLI:

    Generate templates for the following two questions and SQL queries:

1. Question: "Show me flights from SFO to JFK"
SQL:
SELECT
  CAST(_key AS STRING) AS flight_id,
  CAST(info['airline'] AS STRING) AS airline,
  CAST(info['flight_number'] AS STRING) AS flight_number,
  CAST(info['departure_airport'] AS STRING) AS departure_airport,
  CAST(info['arrival_airport'] AS STRING) AS arrival_airport,
  CAST(info['departure_time'] AS STRING) AS departure_time,
  CAST(info['arrival_time'] AS STRING) AS arrival_time,
  CAST(info['departure_gate'] AS STRING) AS departure_gate,
  CAST(info['arrival_gate'] AS STRING) AS arrival_gate,
  CAST(info['departure_city'] AS STRING) AS departure_city,
  CAST(info['arrival_city'] AS STRING) AS arrival_city
FROM
  flights
WHERE
  CAST(info['departure_airport'] AS STRING) = 'SFO'
  AND CAST(info['arrival_airport'] AS STRING) = 'JFK'
ORDER BY
  departure_time;

2. Question: "Tell me flights that can help me beat nighttime traffic if traveling from New York"
SQL:
SELECT
  CAST(info['airline'] AS STRING) AS airline,
  CAST(info['flight_number'] AS STRING) AS flight_number,
  CAST(info['departure_airport'] AS STRING) AS departure_airport,
  CAST(info['departure_time'] AS STRING) AS departure_time
FROM
  flights
WHERE
  CAST(info['departure_city'] AS STRING) = 'New York'
  AND (
    EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) < 17
    OR EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) >= 19
  )
ORDER BY
  departure_time;

  2. Agen mengonversi input Anda ke dalam format tertentu yang meningkatkan performa set konteks di berbagai kueri pengguna. Untuk mengetahui informasi selengkapnya, lihat Ringkasan set konteks.

  3. Tinjau template kueri yang dihasilkan. Anda dapat menyimpan template kueri sebagai file konteks agen baru atau menambahkannya ke file konteks agen yang ada.

  4. Minta agen untuk menyimpan template:

    Save it to context_set.json.

    Agen akan membuat file di direktori yang sama, dengan konten berikut:

    {
  "templates": [
    {
      "nl_query": "Show me flights from SFO to JFK",
      "sql": "SELECT CAST(_key AS STRING) AS flight_id, CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['arrival_airport'] AS STRING) AS arrival_airport, CAST(info['departure_time'] AS STRING) AS departure_time, CAST(info['arrival_time'] AS STRING) AS arrival_time, CAST(info['departure_gate'] AS STRING) AS departure_gate, CAST(info['arrival_gate'] AS STRING) AS arrival_gate, CAST(info['departure_city'] AS STRING) AS departure_city, CAST(info['arrival_city'] AS STRING) AS arrival_city FROM flights WHERE CAST(info['departure_airport'] AS STRING) = 'SFO' AND CAST(info['arrival_airport'] AS STRING) = 'JFK' ORDER BY departure_time",
      "intent": "Find flights from SFO to JFK.",
      "manifest": "Find flights from a given departure airport code to a given arrival airport code.",
      "parameterized": {
        "parameterized_sql": "SELECT CAST(_key AS STRING) AS flight_id, CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['arrival_airport'] AS STRING) AS arrival_airport, CAST(info['departure_time'] AS STRING) AS departure_time, CAST(info['arrival_time'] AS STRING) AS arrival_time, CAST(info['departure_gate'] AS STRING) AS departure_gate, CAST(info['arrival_gate'] AS STRING) AS arrival_gate, CAST(info['departure_city'] AS STRING) AS departure_city, CAST(info['arrival_city'] AS STRING) AS arrival_city FROM flights WHERE CAST(info['departure_airport'] AS STRING) = ? AND CAST(info['arrival_airport'] AS STRING) = ? ORDER BY departure_time",
        "parameterized_intent": "Find flights from ? to ?."
      }
    },
    {
      "nl_query": "Tell me flights that can help me beat nighttime traffic if traveling from New York",
      "sql": "SELECT CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['departure_time'] AS STRING) AS departure_time FROM flights WHERE CAST(info['departure_city'] AS STRING) = 'New York' AND (EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) < 17 OR EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) >= 19) ORDER BY departure_time",
      "intent": "Tell me flights that can help me beat nighttime traffic if traveling from New York",
      "manifest": "Tell me flights that can help me beat nighttime traffic if traveling from a given city",
      "parameterized": {
        "parameterized_sql": "SELECT CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['departure_time'] AS STRING) AS departure_time FROM flights WHERE CAST(info['departure_city'] AS STRING) = ? AND (EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) < 17 OR EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) >= 19) ORDER BY departure_time",
        "parameterized_intent": "Tell me flights that can help me beat nighttime traffic if traveling from ?"
      }
    }
  ]
}

Membuat konteks penelusuran nilai

Di bagian ini, Anda akan membuat konteks penelusuran nilai untuk membantu logika set konteks memetakan frasa nilai ke nilai tertentu yang disimpan di kolom Bigtable menggunakan pencocokan string persis yang tidak peka huruf besar/kecil. Misalnya, jika pengguna meminta penerbangan ke "Raleigh-Durham", penelusuran nilai akan memetakan ini ke nilai database yang disimpan "Raleigh-durham" (kode bandara RDU).

Untuk membuat konteks penelusuran nilai, lakukan langkah-langkah berikut:

  1. Masukkan perintah berikut ke dalam infrastruktur pengelola agen.

    Generate a case-insensitive value search on table "airports" for column "info['city']" with concept "Airport City" using match function "EXACT_MATCH_STRINGS".

  2. Tinjau definisi penelusuran nilai yang dihasilkan. Anda dapat menyimpan definisi penelusuran nilai sebagai file set konteks baru atau menambahkannya ke file set konteks yang ada.

  3. Berikan perintah kepada agen dengan Append the context to context_set.json. Tindakan ini akan menambahkan definisi penelusuran nilai ke file konteks yang dibuat di bagian sebelumnya.

  4. Masukkan instance database dan nama database tempat file set konteks dibuat.

    File konteks yang ada diperbarui dengan definisi penelusuran nilai, dengan konten berikut:

    {
  "templates": [
    {
      "nl_query": "Show me flights from SFO to JFK",
      "sql": "SELECT CAST(_key AS STRING) AS flight_id, CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['arrival_airport'] AS STRING) AS arrival_airport, CAST(info['departure_time'] AS STRING) AS departure_time, CAST(info['arrival_time'] AS STRING) AS arrival_time, CAST(info['departure_gate'] AS STRING) AS departure_gate, CAST(info['arrival_gate'] AS STRING) AS arrival_gate, CAST(info['departure_city'] AS STRING) AS departure_city, CAST(info['arrival_city'] AS STRING) AS arrival_city FROM flights WHERE CAST(info['departure_airport'] AS STRING) = 'SFO' AND CAST(info['arrival_airport'] AS STRING) = 'JFK' ORDER BY departure_time",
      "intent": "Find flights from SFO to JFK.",
      "manifest": "Find flights from a given departure airport code to a given arrival airport code.",
      "parameterized": {
        "parameterized_sql": "SELECT CAST(_key AS STRING) AS flight_id, CAST(info['airline'] AS STRING) AS airline, CAST(info['flight_number'] AS STRING) AS flight_number, CAST(info['departure_airport'] AS STRING) AS departure_airport, CAST(info['arrival_airport'] AS STRING) AS arrival_airport, CAST(info['departure_time'] AS STRING) AS departure_time, CAST(info['arrival_time'] AS STRING) AS arrival_time, CAST(info['departure_gate'] AS STRING) AS departure_gate, CAST(info['arrival_gate'] AS STRING) AS arrival_gate, CAST(info['departure_city'] AS STRING) AS departure_city, CAST(info['arrival_city'] AS STRING) AS arrival_city FROM flights WHERE CAST(info['departure_airport'] AS STRING) = ?

  "facets": [],
  "value_searches": [
    {
      "query": "SELECT CAST(T.info['city'] AS STRING) AS value, 'info:city' AS `columns`, 'Airport City' AS concept_type, 0.0 AS distance, CONCAT('iata=', CAST(T.info['iata'] AS STRING), ', name=', CAST(T.info['name'] AS STRING)) AS context FROM `airports` AS T WHERE LOWER(CAST(T.info['city'] AS STRING)) = LOWER(CAST($value AS STRING))",
      "concept_type": "Airport City",
      "description": "Exact case-insensitive match on airport city name in the airports table."
    }
  ]
}

Mengupload file set konteks ke QueryData

Di bagian ini, Anda akan mengupload file set konteks ke QueryData, sehingga meningkatkan kemampuan pembuatan SQL QueryData di database Anda.

Untuk mengupload konteks, lakukan langkah-langkah berikut:

  1. Di konsol Google Cloud , buka halaman Bigtable.

    Buka Bigtable

  2. Pilih instance dari daftar.

  3. Di menu navigasi, klik Bigtable Studio.

  4. Di panel Explorer, di bagian Context sets dan di samping set konteks flights-assistant, klik ikon View actions ().

  5. Klik Edit context set.

  6. Klik Browse di bagian Upload context file, lalu pilih file set konteks yang dibuat sebelumnya.

  7. Klik Simpan.

Membuat kueri SQL menggunakan QueryData

Di bagian ini, Anda akan menggunakan file set konteks yang telah diupload untuk mengajukan pertanyaan dalam bahasa alami. Dengan demikian, Anda dapat memverifikasi bahwa QueryData memahami dan menerapkan definisi dengan benar untuk istilah seperti nighttime traffic dan frasa terkait lainnya.

Untuk membuat kueri SQL, lakukan langkah-langkah berikut:

  1. Di panel Explorer, di samping set konteks Anda, klik View actions ().
  2. Klik Test context set.
  3. Di editor kueri, klik Generate SQL using QueryData with: flights-assistant.

  4. Untuk membuat kueri SQL, masukkan pertanyaan bahasa alami berikut, lalu klik Generate.

    Tell me flights that can help me beat nighttime traffic if traveling from New York

    Kueri SQL yang dihasilkan akan terlihat mirip dengan berikut ini:

    SELECT
  CAST(info['airline'] AS STRING) AS airline,
  CAST(info['flight_number'] AS STRING) AS flight_number,
  CAST(info['departure_airport'] AS STRING) AS departure_airport,
  CAST(info['departure_time'] AS STRING) AS departure_time
FROM
  flights
WHERE
  CAST(info['departure_city'] AS STRING) = 'New York'
  AND (
    EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) < 17
    OR EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) >= 19
  )
ORDER BY
  departure_time;

    Ini adalah pertanyaan yang sama dengan yang Anda tambahkan ke konteks QueryData. Perhatikan bahwa QueryData kini dapat menafsirkan istilah nighttime traffic secara akurat.

    Meskipun konteksnya berasal dari satu pertanyaan tertentu, QueryData menggunakannya untuk meningkatkan pembuatan SQL untuk berbagai pertanyaan serupa.

  5. Di jendela Generate SQL using QueryData with: flights-assistant, klik Edit.

  6. Masukkan pertanyaan serupa berikut untuk membuat kueri SQL, lalu klik Update.

    What are the flights that can help me avoid evening traffic if departing from Boston

    Karena pertanyaan mengganti istilah nighttime traffic dengan istilah yang serupa, evening traffic, QueryData memberikan jawaban yang konsisten untuk pertanyaan ini dengan menerapkan interpretasi yang sama.

    Kueri SQL yang dihasilkan akan terlihat mirip dengan berikut ini:

    SELECT
  CAST(info['airline'] AS STRING) AS airline,
  CAST(info['flight_number'] AS STRING) AS flight_number,
  CAST(info['departure_airport'] AS STRING) AS departure_airport,
  CAST(info['departure_time'] AS STRING) AS departure_time
FROM
  flights
WHERE
  CAST(info['departure_city'] AS STRING) = 'Boston'
  AND (
    EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) < 17
    OR EXTRACT(HOUR FROM TIMESTAMP(CAST(info['departure_time'] AS STRING))) >= 19
  )
ORDER BY
  departure_time;

  7. Di jendela Generate SQL using QueryData with: flights-assistant, lalu klik Edit.

  8. Masukkan pertanyaan berikut untuk membuat kueri SQL, lalu klik Update.

    Show me flights to Raleigh-Durham

    Kueri SQL yang dihasilkan akan terlihat mirip dengan berikut ini:

    SELECT
  CAST(_key AS STRING) AS flight_id,
  CAST(info['airline'] AS STRING) AS airline,
  CAST(info['flight_number'] AS STRING) AS flight_number,
  CAST(info['departure_airport'] AS STRING) AS departure_airport,
  CAST(info['arrival_airport'] AS STRING) AS arrival_airport,
  CAST(info['departure_time'] AS STRING) AS departure_time,
  CAST(info['arrival_time'] AS STRING) AS arrival_time,
  CAST(info['departure_gate'] AS STRING) AS departure_gate,
  CAST(info['arrival_gate'] AS STRING) AS arrival_gate,
  CAST(info['departure_city'] AS STRING) AS departure_city,
  CAST(info['arrival_city'] AS STRING) AS arrival_city
FROM
  flights
WHERE
  CAST(info['arrival_city'] AS STRING) = 'Raleigh-durham'
ORDER BY
  departure_time;

    Perhatikan bahwa QueryData kini dapat memetakan Raleigh-Durham secara akurat ke nilai tersimpan "Raleigh-durham" (RDU).

Mengintegrasikan QueryData dengan aplikasi Anda

Di bagian ini, Anda akan membuat agen data untuk aplikasi pencarian penerbangan. Agen data ini menyediakan antarmuka percakapan ke tabel flights dan airports yang Anda buat sebelumnya. Dokumen ini juga menjelaskan cara membuat dan mengintegrasikan agen data ini ke dalam aplikasi Anda menggunakan Agent Development Kit (ADK), alat MCP QueryData Gemini Data Analytics, dan set data konteks untuk meningkatkan kualitas respons.

  1. Download MCP Toolbox versi 1.14.0 atau yang lebih baru. MCP Toolbox mengekspos agen data sebagai alat yang dapat dihubungkan oleh aplikasi. MCP Toolbox berbeda dengan agen rekayasa konteks yang Anda instal sebelumnya, yang menghasilkan konteks.

  2. Siapkan Kredensial Default Aplikasi (ADC).

    gcloud auth application-default login

  3. Temukan ID set konteks yang Anda buat sebelumnya. Untuk mengetahui informasi selengkapnya tentang cara menemukan ID set konteks, lihat Menemukan ID set konteks.

  4. Tambahkan kode berikut ke konfigurasi tools.yaml untuk terhubung ke agen data menggunakan MCP Toolbox. Untuk mengetahui informasi selengkapnya, lihat Sumber Analisis Data Gemini dan Alat QueryData Analisis Data Gemini.

  5. Jalankan server MCP Toolbox dengan file tools.yaml.

    ./toolbox --config PATH_TO_TOOLS_YAML

    Ganti PATH_TO_TOOLS_YAML dengan jalur ke file tools.yaml yang Anda buat sebelumnya.

  6. Membuat aplikasi ADK yang memanggil alat QueryData Gemini Data Analytics menggunakan Python SDK MCP Toolbox. Untuk mengetahui informasi selengkapnya tentang cara menggunakan SDK Python MCP Toolbox, lihat panduan memulai Toolbox dan untuk ADK Python, lihat panduan memulai ADK.

    1. Buat direktori untuk menyimpan aplikasi, misalnya flight-assistant-app.

    2. Ubah direktori ke direktori flight-assistant-app.

      mkdir flight-assistant-app
cd flight-assistant-app

    3. Jalankan perintah berikut di direktori flight-assistant-app untuk membuat lingkungan virtual dan menginstal komponen yang diperlukan.

      uv init
uv add google-adk toolbox-core google-genai

    4. Menyiapkan agen ADK.

      1. Membuat agen ADK.

        uv run adk create my_agent

      2. Pilih model gemini-2.5-flash, atau yang lebih baru.

      3. Pilih Google AI, lalu masukkan kunci Gemini API Anda. Untuk mengetahui informasi selengkapnya tentang cara menemukan kunci API Anda, lihat Menggunakan kunci Gemini API. (Atau, jika Anda tidak memerlukan uji coba gratis, Anda dapat memilih Vertex AI dan menentukan project Google Cloud dengan penagihan yang diaktifkan).

    5. Ganti konten file agent.py dengan kode aplikasi contoh Flight Data Assistant berikut.

      from typing import cast

  7. Untuk memulai aplikasi, jalankan perintah berikut di direktori flight-assistant-app. Akses server web ADK di http://127.0.0.1:8000.

    uv run adk web --port 8000

  8. Masukkan teks apa pun, seperti hello, untuk mulai berinteraksi dengan agen.

    Agen ADK menjawab pertanyaan umum dan memanggil alat MCP yang diperlukan.

  9. Masukkan pertanyaan terkait penerbangan berikut.

    How many flights depart from the west side?

    Alat MCP dipanggil untuk menjawab pertanyaan ini. Karena database tidak menentukan the west side, QueryData mengasumsikan daftar bandara West Coast dan menampilkan jumlah penerbangan serta penjelasan, yang digunakan agen untuk mengklarifikasi asumsi dalam responsnya:

    There are 253 flights departing from the west side.

Please note that "the west side" is not explicitly defined in our records, so this count assumes flights departing from major West Coast airports: Los Angeles (LAX), San Francisco (SFO), San Diego (SAN), Seattle (SEA), Portland (PDX), Las Vegas (LAS), and Phoenix (PHX). If you had a different set of airports in mind, please let me know!

  10. Masukkan pertanyaan yang mirip dengan pertanyaan di template kueri yang dibuat untuk agen.

    Help me find flights from San Francisco that avoid the evening rush hour.

    Berdasarkan konteks QueryData yang ditambahkan sebelumnya, alat MCP memahami bahwa evening traffic terjadi antara pukul 17.00 dan 19.00. Alat MCP menampilkan data terkait untuk digunakan agen dalam menyusun responsnya.

    Here are the flights departing from San Francisco that avoid the evening rush hour (defined as 5 PM to 7 PM):

* UA 1532 departing at 05:50:00
* UA 1158 departing at 05:57:00
* CY 922 departing at 06:38:00
* OO 5441 departing at 07:08:00
* UA 616 departing at 07:14:00
* AA 24 departing at 07:14:00
* B6 434 departing at 08:00:00
* AA 242 departing at 08:18:00
* UA 1739 departing at 08:22:00
* OO 6336 departing at 08:32:00
* US 1784 departing at 08:47:00
* DL 1631 departing at 09:00:00
* DL 1106 departing at 09:06:00
* OO 5427 departing at 09:06:00
* CY 352 departing at 09:25:00

  11. Masukkan pertanyaan berdasarkan jenis konsep yang Anda tambahkan dalam konteks agen QueryData.

    Show me flights to Raleigh-Durham

    Berdasarkan konteks penelusuran nilai yang ditambahkan sebelumnya, agen memahami bahwa "Raleigh-Durham" cocok dengan kota yang disimpan "Raleigh-durham" (kode bandara RDU) dan menampilkan data terkait untuk digunakan agen dalam membuat responsnya.

    Here is the flight heading to Raleigh-Durham (RDU):

* Flight UA 1568 departs from San Francisco (SFO) at Gate A30 on 2025-01-02 at 14:55:00 and arrives at Raleigh-Durham (RDU) at Gate A26 on 2025-01-02 at 23:03:00.

Melakukan iterasi performa agen

UI web ADK memungkinkan Anda memeriksa permintaan dan respons dari alat MCP QueryData Analisis Data Gemini. Anda dapat menggunakan respons ini untuk mengamati respons alat seperti kueri SQL yang dihasilkan, set hasil, penjelasan intent, pertanyaan disambiguasi, dan jawaban natural language, untuk membantu Anda mengonfirmasi kebenaran respons agen.

Misalnya, untuk teks input How many flights depart from the west side? yang Anda masukkan sebelumnya, klik balon agen. Di tab Event di navigasi kiri, luaskan functionResponse untuk melihat respons berikut.

{"result": "{"generatedQuery":"SELECT COUNT(*) AS flight_count FROM flights WHERE CAST(info['departure_airport'] AS STRING) IN ('LAX', 'SFO', 'SAN', 'SEA', 'PDX', 'LAS', 'PHX')","intentExplanation":"The user is asking for the number of flights departing from the 'west side'. Since there is no explicit definition or column for 'west side' in the schema, I will assume this refers to major airports on the West Coast of the United States (e.g., LAX, SFO, SAN, SEA, PDX, LAS, PHX).","queryResult":{"columns":[{"name":"flight_count"}],"rows":[{"values":[{"value":"253"}]}],"totalRowCount":"1"},"naturalLanguageAnswer":"There are 253 flights departing from West Coast airports (LAX, SFO, SAN, SEA, PDX, LAS, PHX)."}"}

Mempertajam akurasi respons

Anda dapat terus meningkatkan akurasi respons dari alat QueryData Gemini Data Analytics dengan menambahkan konteks tambahan. Gunakan agen rekayasa konteks untuk membuat konteks, lalu upload file set konteks yang diperbarui ke agen data flights-assistant yang ada. Untuk mengetahui informasi selengkapnya, lihat Mengelola set konteks di Bigtable Studio. Konsol akan segera menyerap konteks baru setelah Anda menguploadnya, sehingga Anda dapat meningkatkan akurasi agen tanpa waktu nonaktif aplikasi.

Beberapa agen

Di lingkungan pengembangan, Anda dapat melakukan pengujian A/B pada beberapa konteks agen data dengan menetapkan nama yang berbeda untuk alat dalam file tools.yaml. Misalnya, Anda dapat membuat konfigurasi tools.yaml yang unik dengan menentukan dua alat cloud-gemini-data-analytics-query dengan nama yang berbeda, seperti cloud_gda_query_tool_v1 dan cloud_gda_query_tool_v2. Penyiapan ini memungkinkan Anda menerapkan logika aplikasi yang secara terprogram memilih versi konteks yang diperlukan dengan memilih nama alat yang sesuai.

Contoh tools.yaml berikut menunjukkan cara menyiapkan beberapa agen data untuk sumber database:

kind: source
name: gda-api-source
type: cloud-gemini-data-analytics
projectId: PROJECT_ID
---
kind: tool
name: cloud_gda_query_tool_v1
type: cloud-gemini-data-analytics-query
source: gda-api-source
context:
  datasourceReferences:
    DB_SOURCE:
      databaseReference: ...
      agentContextReference:
        contextSetId: "V1_YOUR_CONTEXT_SET_ID"
generationOptions: ...

    DB_SOURCE:
      databaseReference: ...
      agentContextReference:
        contextSetId: "V2_YOUR_CONTEXT_SET_ID"
generationOptions: ...

Ganti kode berikut:

  • PROJECT_ID: Project ID Google Cloud Anda.
  • V1_YOUR_CONTEXT_SET_ID: ID set konteks untuk versi 1.
  • V2_YOUR_CONTEXT_SET_ID: ID set konteks untuk versi 2.
  • DB_SOURCE: konfigurasi sumber database.
