ADK Agent Builder
Build production-ready agents with Google’s Agent Development Kit (ADK): scaffolding, tool wiring, orchestration patterns, testing, and optional deployment to Vertex AI Agent Engine.
Overview
- Creates a minimal, production-oriented ADK scaffold (agent entrypoint, tool registry, config, and tests).
- Supports single-agent ReAct-style workflows and multi-agent orchestration (Sequential/Parallel/Loop).
- Produces a validation checklist suitable for CI (lint/tests/smoke prompts) and optional Agent Engine deployment verification.
Prerequisites
- Python runtime compatible with your project (often Python 3.10+)
google-adk installed and importable- If deploying: access to a Google Cloud project with Vertex AI enabled and permissions to deploy Agent Engine runtimes
- Secrets available via environment variables or a secret manager (never hardcoded)
Instructions
- Confirm scope: local-only agent scaffold vs Vertex AI Agent Engine deployment.
- Choose an architecture:
- Single agent (ReAct) for adaptive tool-driven tasks
- Multi-agent system (specialists + orchestrator) for complex, multi-step workflows
- Define the tool surface (built-in ADK tools + any custom tools you need) and required credentials.
- Scaffold the project:
src/agents/, src/tools/, tests/, and a dependency file (pyproject.toml or requirements.txt)
- Implement the minimum viable agent and a smoke test prompt; add regression tests for tool failures.
- If deploying, produce an
adk deploy ... command and a post-deploy validation checklist (AgentCard/task endpoints, permissions, logs).
Output
- A repo-ready ADK scaffold (files and directories) plus starter agent code
- Tool stubs and wiring points (where to add new tools safely)
- A test + validation plan (unit tests and a minimal smoke prompt)
- Optional: deployment commands and verification steps for Agent Engine
Error Handling
- Dependency/runtime issues: provide pinned install commands and validate imports.
- Auth/permission failures: identify the missing role/API and propose least-privilege fixes.
- Tool failures/rate limits: add retries/backoff guidance and a regression test to prevent recurrence.
Examples
Example: Scaffold a single ReAct agent
