AI agents have taken center stage in automating tasks and enhancing productivity, making them a hot topic across industries. From answering nuanced questions to orchestrating complex workflows, their capabilities are impressive — but far from perfect. Building and deploying AI agents comes with significant challenges that developers and organizations must address to unlock their full potential.
Here’s a closer look at the key limitations of AI agents, from the intricacies of building them to ensuring they run reliably at scale.
Writing AI Agents from scratch
One of the toughest parts of building AI agents is that, for now, you’re largely starting from scratch. Sure, frameworks like LangChain or Haystack can help with some of the heavy lifting, but they don’t cover everything. You’re still left figuring out how to tie it all together, which can feel like solving a giant jigsaw puzzle with missing pieces.
Now, let’s say you find a cool tool on GitHub that could make your AI agent smarter or faster. Maybe it’s a script for scraping specific types of data or an algorithm that performs advanced analysis. It’s exciting — until you try to actually use it. More often than not, these tools aren’t plug-and-play. You might run into vague or incomplete documentation, leaving you scratching your head about how to even start. Worse, the tool might not be hosted anywhere, meaning it’s up to you to set up a server or cloud instance just to get it running.
Even when things seem straightforward, integrating a new tool into your AI agent can quickly turn into a rabbit hole. Does the tool’s output match what your agent expects? If not, you’ll need to write extra code to make it fit. What happens if the tool needs updates or suddenly stops working? Now you’re not just building an AI agent — you’re managing an ecosystem of moving parts, each of which requires constant attention.
Context handling
One of the most impressive feats of an AI agent is maintaining context over long interactions or multi-step workflows. But let’s be honest — this is easier said than done. Without proper context management, agents can “lose the plot” midway, forgetting previous inputs or misunderstanding follow-up instructions.
For example, imagine an AI agent helping plan a trip. If it forgets the location you mentioned in the first step, the entire interaction breaks down. Context handling challenges include:
- Memory limits: Large language models (LLMs) have token limits, making it difficult to manage extended conversations or tasks.
- State management: Ensuring the agent retains and applies relevant information across multiple steps.
Without strong context-handling mechanisms, agents struggle to deliver reliable and coherent outputs.
Prompt maintenance
AI agents rely on carefully crafted prompts to function effectively. Think of prompts as the “instructions” that guide the agent. However, maintaining prompts over time is a challenge, especially as the agent grows in complexity.
For example:
- Adding a new tool or API may require revising existing prompts to ensure compatibility.
- Poorly structured prompts can lead to ambiguous or incorrect responses.
- Keeping track of prompt changes across different versions of the agent can become a logistical headache.
Without a robust system for managing and refining prompts, even well-designed agents can falter.
Error handling
No system is perfect, and AI agents are no exception. APIs go down, tools fail, and network issues crop up. What happens when something breaks? Without proper fallback mechanisms, many agents simply crash or return an error message.
Effective error handling requires:
- Backup strategies: If one tool or API fails, the agent should try another approach or notify the user gracefully.
- Resilience testing: Anticipating potential failures and building systems that can recover quickly.
Developers often underestimate the complexity of error handling, but it’s a crucial component of any robust AI agent.
Security and privacy
When agents interact with sensitive data — whether it’s personal information, financial records, or proprietary business data — security becomes a top priority. Every integration with an external tool or API introduces potential vulnerabilities. Key concerns include:
- Data encryption: Ensuring all communication between the agent and tools is secure.
- Access control: Limiting who or what can access sensitive data.
- Compliance: Meeting regulations like GDPR, HIPAA, or other industry-specific standards.
Without a strong focus on security, agents risk becoming liabilities rather than assets.
Scalability
As AI agents grow in complexity, so do the challenges of scaling them effectively. Adding more tools, APIs, or even other agents to the system creates a web of dependencies that can quickly become unwieldy. Common scalability challenges include:
- Performance bottlenecks: Ensuring the system remains fast and responsive as the workload increases.
- Orchestration at scale: Managing workflows involving multiple agents and tools without delays or errors.
- Cost management: Scaling often requires more computational resources, which can drive up costs.
Without careful planning and optimization, scaling an AI agent can lead to degraded performance and spiraling expenses.
How platforms like mkinf help
With all these challenges, it’s no wonder that developing and deploying AI agents often feels overwhelming. That’s where platforms like mkinf step in. By offering deployment-ready, customizable building blocks, mkinf allows developers to bypass many of these hurdles without sacrificing flexibility.
Instead of writing every component from scratch, you can leverage mkinf’s pre-built tools and APIs, which are not only designed to work seamlessly together but also customizable to fit your specific project needs. This approach takes the pain out of integration, simplifies prompt maintenance, and ensures robust error handling. It’s also built to scale, so your agents can grow alongside your ambitions, all while keeping security and privacy front and center.
