"""Example agent using BigQuery toolset with a 1P skill for guided workflows.

This sample demonstrates the pattern of combining a raw toolset (BigQueryToolset)
with a curated skill (SkillToolset) to provide both tools and guided workflows
to the agent.

Setup:
  1. Install ADK with BigQuery extras: pip install google-adk[bigquery]
  2. Configure OAuth credentials (see README.md)
  3. Run: adk web contributing/samples
