ADK Engineer

Name: adk-engineer
Author: jeremylongshore

Engineer production-ready Agent Development Kit (ADK) agents and multi-agent systems: clean structure, testability, safe tool usage, and deployment automation.

Overview

Use this skill to design and implement ADK agent code that is maintainable and shippable: clear module boundaries, structured tool interfaces, regression tests, and a deployment checklist (local or Agent Engine).

Prerequisites

A target runtime (Python/Java/Go) consistent with the project’s pinned versions
ADK installed (and any required model/provider SDKs configured)
A test runner available in the repo (unit tests at minimum)
If deploying: access to a Google Cloud project and permissions for the chosen deployment target

Instructions

Clarify requirements: agent goals, tool surface, latency/cost constraints, and deployment target.
Propose architecture: single agent vs multi-agent, orchestration pattern, state strategy (Memory Bank / external store).
Scaffold structure: agent entrypoint(s), tool modules, config, and tests.
Implement incrementally:
- add one tool at a time with input validation and structured outputs
- add regression tests for each tool and critical prompt flows
Add operational guardrails: retries/backoff, timeouts, logging, and safe error messages.
Validate locally (tests + smoke prompts) and provide a deployment plan (when requested).

Output

A concrete architecture plan and file layout
Agent and tool implementations (or patches) with tests
A validation checklist (commands to run, expected outputs, and failure triage)
Optional: deployment instructions and post-deploy health checks

Error Handling

Build/test failures: isolate the failing module, minimize the repro, fix, and add a regression test.
Tool/runtime errors: enforce structured error responses and safe retries where appropriate.
Deployment failures: provide the exact failing command, logs to inspect, and least-privilege IAM fixes.

Examples

Example: Productionizing an existing ADK agent

Request: “Refactor this agent into a clean module structure and add tests before we deploy.”
Result: reorganized src/ layout, tool boundaries, a test suite, and a deployment checklist.

Example: Multi-agent workflow

Request: “Build a validator + deployer + monitor agent team with a sequential orchestrator.”
Result: orchestrator skeleton, per-agent responsibilities, and smoke tests for each step.
