What is Agentic Workflow?

Before we dive into ADKs, let’s define what an “agentic workflow” entail. An agentic workflow is a sequence of actions performed by an AI Agent to achieve a specific goal. Unlike traditional software workflows that are pre-defined and linear, agentic workflows are dynamic and adaptive. The agent can:

  • Plan: Decompose a complex task into smaller, manageable steps.
  • Reason: Evaluate different options and make decisions based on available information.
  • Act: Execute actions in the real world through APIs, tools, or interactions with other systems.
  • Reflect (self-evaluate and correct mistakes)
  • Learn: Adapt its behavior over time based on its experiences and feedback.

Agentic workflows enable AI to tackle problems that are too complex or unpredictable for traditional automation.

Challenges of Implementing ADKs and Migrating Between Them:

While ADKs simplify AI Agent development, there are still several challenges to consider:

  • Migration Complexity: Moving between ADKs requires rearchitecting agent logic, tool integrations, and workflow orchestration due to platform-specific APIs and paradigms.​
  • Learning Curve: Each ADK has unique abstractions, documentation, and best practices, requiring significant upskilling.​
  • Vendor Lock-in: Deep integration with specific ecosystems (OpenAI or Google) can limit flexibility and increase migration costs.​
  • Tool Compatibility: Not all tools or APIs are natively supported across different ADKs, necessitating custom adapters or wrappers.
  • Complexity: Agentic AI is inherently complex, requiring a deep understanding of AI principles, software engineering, and domain expertise.
  • Integration: Integrating AI Agents with existing systems and workflows can be challenging.
  • Scalability: Scaling AI Agent deployments to handle large volumes of traffic can be complex and expensive.

  • Perform complex analyses

Conclusion

Agent Development Kits represent the next frontier in AI application development. While they offer tremendous potential for building sophisticated AI systems, they also introduce new complexities that developers must navigate carefully.

The choice of ADK should be driven by your specific use case, team capabilities, and long-term strategy. There’s no one-size-fits-all solution — LangChain offers flexibility, OpenAI provides simplicity, Google and AWS deliver enterprise features, and specialized frameworks like CrewAI excel at specific patterns.

The key to success lies not just in selecting the right framework, but in understanding the fundamental patterns of agentic workflows, implementing robust error handling, maintaining flexibility through abstraction, and continuously iterating based on real-world performance.

As the field matures, we can expect better tools, clearer patterns, and more standardization. But for now, building effective AI agents remains as much art as science — requiring careful design, extensive testing, and a willingness to learn from both successes and failures.

Whether you’re building a simple task automation system or a complex multi-agent orchestration platform, the principles remain the same: start simple, measure everything, fail fast, and iterate continuously. The agents of tomorrow will be built by developers who master these fundamentals today.
