Jeremy Adk Software Engineer

Production-grade software engineering for Google Agent Development Kit (ADK) applications. Covers the full lifecycle: architecture design, agent implementation, testing, deployment automation, and multi-agent orchestration.

Overview

This plugin provides an auto-activating skill that acts as a senior ADK software engineer. It helps you build maintainable, testable, and deployable ADK agents following Google Cloud best practices. Whether you are creating a single-agent tool-calling application or a multi-agent orchestration pipeline, this plugin delivers structured code, comprehensive tests, and deployment-ready configurations.

Installation

/plugin install jeremy-adk-software-engineer@claude-code-plugins-plus

Features

• Agent Architecture Design: Single-agent and multi-agent system patterns (Sequential, Parallel, Loop)
• Clean Code Implementation: Modular project structure with proper separation of concerns
• Comprehensive Testing: Unit, integration, and end-to-end test scaffolding with pytest
• Deployment Automation: CI/CD pipelines for Agent Engine, Cloud Run, and GKE
• Tool Engineering: Typed tool interfaces with FunctionTool, input validation, and structured outputs
• Orchestration Patterns: SequentialAgent, ParallelAgent, and custom workflow coordination
• Production Guardrails: Retries with backoff, timeouts, structured logging, and safe error messages
• Multi-Language Support: Python (primary), Java, and Go

Components

Trigger Phrases

• "Build an ADK agent application"
• "Create production-ready ADK code"
• "Engineer a multi-agent system"
• "Implement ADK agent with tests"
• "Set up ADK development environment"
• "Design ADK agent architecture"

Prerequisites

• Python 3.11+ (or Java/Go for alternative runtimes)
• google-adk package installed (pip install google-adk)
• Google Cloud project with Vertex AI API enabled
• gcloud CLI authenticated with appropriate IAM roles
• pytest for running tests (pip install pytest pytest-cov)

Quick Start

pip install google-adk google-cloud-aiplatform[agent_engines]

Then ask Claude: "Build an ADK agent that [your use case]"

Correct SDK Patterns

# Agent import (correct)
from google.adk.agents import Agent
from google.adk.tools import FunctionTool

# Define a tool as a plain function
def get_weather(city: str) -> dict:
    """Fetch weather for a city."""
    return {"city": city, "temp_c": 22, "condition": "sunny"}

# Create agent with wrapped tools
root_agent = Agent(
    name="weather_agent",
    model="gemini-2.5-flash",
    description="Answers weather questions for any city.",
    instruction="Use the get_weather tool to answer user questions.",
    tools=[FunctionTool(func=get_weather)],
)

adk web  # Opens browser chat at http://localhost:8000

Deployment

# Deployment via SDK
import vertexai
client = vertexai.Client(project="PROJECT_ID", location="us-central1")
remote_agent = client.agent_engines.create(
    agent=app,
    config={
        "requirements": ["google-cloud-aiplatform[agent_engines,adk]"],
        "staging_bucket": "gs://BUCKET",
    },
)

# Deployment via CLI
# adk deploy agent_engine --project=PROJECT --region=REGION agent_module

> Note: There is no gcloud CLI for Agent Engine management. Use the Python SDK (vertexai.Client().agent_engines.*) or the adk CLI for deployment.

Use Cases

• Greenfield Agent Development: Scaffold a new ADK project from scratch with best practices
• Production Hardening: Add tests, error handling, and monitoring to an existing agent
• Multi-Agent Systems: Design and implement orchestrated agent teams
• CI/CD Pipelines: Generate GitHub Actions workflows for automated testing and deployment
• Code Review Agents: Build agents that lint, review, and analyze code quality

Integration

Works with:

• jeremy-gcp-starter-examples -- ADK sample code from google/adk-samples
• jeremy-vertex-validator -- Validate agents before deployment
• jeremy-vertex-engine -- Inspect deployed agents
• jeremy-adk-orchestrator -- A2A protocol orchestration
