Why AI Agents Say “Done” When the Task Actually Failed

Safiyev Marat — Tue, 11 Aug 2026 07:51:54 +0000

AI agents have a surprisingly simple reliability problem:

They often confuse performing an action with completing a task.

An agent clicks a button.

The tool call succeeds.

The model assumes the job is finished.

And then you get:

Done ✅

But maybe the page returned an error.

Maybe the file wasn't created.

Maybe the message wasn't sent.

Maybe the application never opened.

The action succeeded.

The task didn't.

The False Completion Problem

Imagine asking an agent:

“Create a Google Doc called Project Plan.”

A naive agent might:

Open Google Docs
Click “New document”
Enter the title
Report success

But clicking buttons isn't proof that the document actually exists.

For autonomous agents, this becomes a serious problem.

The longer the workflow, the worse it gets.

One incorrect assumption early in the process can make every step after it useless.

How HeyAgent Handles It

While building HeyAgent, I decided that executing the last action should not automatically mean the task is complete.

The basic workflow looks like this:


text
Request
   ↓
Plan
   ↓
Execute
   ↓
Verify
   ↓
Success

And if verification fails:

Execute
   ↓
Verify
   ↓
Failure detected
   ↓
Retry / continue execution

HeyAgent has a separate verification stage after execution.

Instead of trusting the model's assumption that something worked, the system checks for evidence that the expected result was actually produced.

Only after that verification passes should the task be considered completed.

Why This Matters

There is a big difference between:

tool_call = success

and:

user_goal = achieved

The first tells us that an operation ran.

The second tells us that the agent actually did what the user asked.

For simple chat assistants, this distinction may not matter much.

For agents controlling browsers, files, terminals, desktop applications, and external services, it matters a lot.

If we want AI agents to perform real work reliably, they can't just be good at taking actions.

They also need to understand whether those actions actually worked.

That's one of the reliability problems I'm trying to solve with HeyAgent.

HeyAgent is fully open source, so you can explore the architecture, test it, break it, and contribute.

I Built an Open-Source AI Agent That Actually Controls Your Computer

Safiyev Marat — Mon, 03 Aug 2026 15:27:18 +0000

AI agents are everywhere in 2026.

Most of them can answer questions, generate code, or automate simple workflows. But once you ask them to interact with a real computer—browsers, desktop applications, terminals, files, and external services—things quickly become unreliable.

That was the motivation behind HeyAgent.

The Problem

Most autonomous agents fail for one of three reasons:

They declare success before the task is actually finished.
They lose context during long, multi-step workflows.
They aren't designed to work with a real desktop environment.

I wanted to build an agent that behaves more like a real assistant instead of just another LLM wrapper.

What HeyAgent Does

HeyAgent is an open-source autonomous AI agent for computer control and workflow automation.

It can:

🖥️ Control desktop applications
🌐 Work inside browsers
📂 Read and manage files
💻 Execute terminal commands
🔗 Connect with external services
📱 Be controlled through CLI, Desktop UI, or Telegram
🧠 Plan and execute multi-step workflows
✅ Verify results before marking tasks as completed

Instead of blindly executing prompts, the agent plans, executes, validates the outcome, and only then reports success.

Reducing False Task Completion

One of the biggest problems I noticed in existing AI agents is false task completion.

Many agents click a button, assume everything worked, and immediately report success.

In reality, something may have failed several steps earlier.

HeyAgent performs additional verification after critical actions to reduce false positives and improve reliability during long-running workflows.

Built with AWS Support

HeyAgent has been significantly accelerated thanks to the support of AWS.

AWS has provided the project with cloud infrastructure, GPU computing resources, and access to modern AI services that made rapid experimentation possible throughout development.

From running GPU workloads to evaluating different LLMs and AI models, AWS has been an important part of the engineering process. Their continued support allows us to iterate faster, test new ideas, and focus on improving the product instead of worrying about infrastructure limitations.

We're genuinely grateful to AWS for supporting open-source innovation and continuing to help us build HeyAgent.

Tech Stack

TypeScript
Node.js
Model-agnostic architecture
Cloud and local LLM support
Plugin-based tool system
Multi-step execution engine

The goal isn't to lock developers into one model.

Whether you prefer cloud providers or local models, HeyAgent is designed to work with both.

Why Open Source?

AI agents shouldn't become black boxes.

Developers should be able to inspect the reasoning flow, build their own tools, contribute improvements, and adapt the platform to their own workflows.

That's why HeyAgent is fully open source.

What's Next?

Development is moving fast, and we're actively working on:

Better planning and reasoning
More reliable desktop automation
A richer plugin ecosystem
Improved routing and execution
Support for additional AI models and integrations

We'd Love Your Feedback

If you're building AI agents, automation tools, or desktop software, I'd love to hear your thoughts.

Feedback, ideas, bug reports, and pull requests are always welcome.
