Ask HN: Are Agents Just Hype?

5 points by spacemnstr42069 a day ago

I have spent the last few days trying (and failing) to find real cases where AI agents actually scale in production. Outside of coding agents and dev-productivity tools, I am struggling to see anything that looks like a genuinely scalable agent system.

Most of what people are calling “agents” today are basically deterministic workflows with one or two LLM calls glued together. That is not an agent. That is a at best API pipeline.

So I am genuinely curious: are there any real examples of agents handling large, messy, multi-step workflows at scale? Not demos, not toy projects, not VC decks.

Cursor has been doing this in production since the start of 2025. You give it instructions or heck, a screenshot of a bug. It searches for relevant code based on the problem. It searches in an area around the code, for tests, behaviors. If you've written a comment pointing to Jira on a certain bug that this code is responsible for fixing (instead of writing a test), it can check that ticket for expected behavior. It may write tests to fill in these gaps or it may just write the code. Then it runs the tests if possible. If a test fails, it compares to the new code. It writes new code and reruns tests.

Tool-use is common in most of the major AI models now and it's really the differentiator between how they perform when writing code. Few write correct code the first time. What makes them different is the ability to read and modify complex code across multiple files, without being told which files.

I think by next year, we could see this extend across the UI domain - it writes code, runs it, views the UI, critiques the results, then tweaks things like font and whitespace. I did a prototype mid-year which would even show it to a user, and it would talk them through what they liked or didn't like. But you can even chain it between multiple LLMs (designer, programmer, customer roles) and it would fit your definition.

    Agreed, but as mentioned in the original post, I am looking for use cases out of coding agents. Coding agents are scaling, yes! What are other use cases?

A lot of things are happening behind closed doors.

The real value is in horribly manual internal processes where the solutions are agents driving very specific tools that drive weird and wacky systems.

Generic out of the box agents that will solve your particular problem are not a thing yet.

In regard to it’s just an “API pipeline” - the power of agents should be - which set of API calls do I string together to solve a user’s request.

    Can you share some examples of these things behind the door? I am really looking to identify few of these use cases.

No they work fine. Not a panacea, but when the use case permits.

Usually layers of tools clustered under sub-agents, and fairly detailed orchestration prompts at higher levels. Orchestration via agent-prompts can be better than hard-coded workflows when they require qualitative assessments.

There probably are examples out there but paywalled heavily as they probably still make more money from selling the guides than actually using the agents.

    You mean agent is not value? Selling guides making money, lol!
