BigQuery Agent Analytics SDK

An open-source Python SDK for analyzing, evaluating, and curating agent traces stored in BigQuery. Built on top of the BigQuery Agent Analytics, it provides a consumption-layer toolkit for agent observability, analysis, evaluation, and advanced capabilities like context graph at scale.

Overview

The BigQuery Agent Analytics SDK connects your AI agent telemetry in BigQuery to a rich set of evaluation, observability, and analytics capabilities. It is designed for ML engineers, data scientists, and platform teams who run agents in production and need to understand agent behavior, measure quality, and detect regressions — all through BigQuery SQL or Python.

Key Features

Observability

• Trace reconstruction and DAG visualization
• Per-event-type BigQuery views
• Observability dashboards (SQL and BigFrames)

Evaluation

• Code-based metrics (latency, turn count, error rate, token efficiency, cost)
• LLM-as-Judge scoring (correctness, hallucination, sentiment)
• Trajectory matching (exact, in-order, any-order)
• Multi-trial evaluation with pass@k / pass^k
• Grader composition (weighted, binary, majority strategies)
• Eval suite lifecycle management with graduation and saturation detection
• Static quality validation (ambiguous tasks, class imbalance, suspicious thresholds)

AI/ML Integration

• BigQuery AI.GENERATE, AI.EMBED, AI.CLASSIFY
• Anomaly detection and latency forecasting
• Categorical (Hatteras-style) evaluation via BigFrames

Advanced Analytics

• Context Graph — property graph linking traces to business entities with GQL traversal
• YAML-driven ontology extraction and materialization
• Long-horizon cross-session memory
• Multi-stage agent insights pipeline
• Drift detection for golden vs production question distributions

CLI (bq-agent-sdk)

• 12+ commands for diagnostics, evaluation, and CI/CD integration

Deployment Surfaces

• Remote Function (BigQuery SQL via Cloud Run)
• Python UDF scoring kernels
• Streaming evaluation (Cloud Scheduler + Cloud Run)
• Continuous query templates

Usage Telemetry

• Every job the SDK submits is labeled (sdk, sdk_version, sdk_surface, sdk_feature, and sdk_ai_function where relevant) so operators can attribute spend, latency, and adoption directly from INFORMATION_SCHEMA.JOBS_BY_PROJECT. No extra telemetry pipeline is required. See docs/sdk_usage_tracking.md for the label schema and ready-to-run tracking queries.

Prerequisites

• Python 3.10+
• A Google Cloud project with BigQuery enabled
• Agent traces stored in BigQuery via the ADK BigQuery Trace Exporter

Installation

pip install bigquery-agent-analytics

With optional LLM judge support:

pip install bigquery-agent-analytics[llm]

With BigFrames support:

pip install bigquery-agent-analytics[bigframes]

Quick Start

from bigquery_agent_analytics import Client

client = Client(project_id="my-project", dataset_id="analytics")
trace = client.get_trace("trace-abc-123")
trace.render()
