Staring at your phone while waiting for your agent to prompt you again. Code monkey might actually be real this time
deadbabe•48m ago
I think we all know what Agentic engineering is, the question is when should it not be used instead of classical engineering?
kevintomlee•47m ago
the practice of developing software with the assistance of coding agents.

Spot on.

How is this different than Prompt Engineering?
ares623•44m ago
"Prompt" was derogatory /s
bigfishrunning•24m ago
It just meant they showed up on time.
giancarlostoro•38m ago
Prompt engineering was coined before tooling like Claude Code existed, when everyone copied and pasted from chatgpt to their editor and back.

Agentic coding highlights letting the model directly code on your codebase. I guess its the next level forward.

I keep seeing agentic engineering more even in job postings, so I think this will be the terminology used to describe someone building software whilst letting an AI model output the code. Its not to be confused with vibe coding which is possible with coding agents.

simonw•16m ago
Prompt engineering didn't imply coding agents. That's the big difference: we are now using tools write and execute the code, which makes for massively more useful results.
maxbond•40m ago
I don't think we should be making this distinction. We're still engaged in software engineering. This isn't a new discipline, it's a new technique. We're still using testing, requirements gathering, etc. to ensure we've produced the correct product and that the product is correct. Just with more automation.
ssgodderidge•29m ago
I agree, partly. I feel the main goal of the term “agentic engineering” is to distinguish the new technique of software engineering from “Vibe Coding.” Many felt vibe coding insinuated you didn’t know what you were doing; that you weren’t _engineering_.

In other words, “Agentic engineering” feels like the response of engineers who use AI to write code, but want to maintain the skill distinction to the pure “vibe coders.”

simonw•10m ago
Yeah, I see agentic engineering as a sub-field or a technique within software engineering.

I entirely agree that engineering practices still matter. It has been fascinating to watch how so many of the techniques associated with high-quality software engineering - automated tests and linting and clear documentation and CI and CD and cleanly factored code and so on - turn out to help coding agents produce better results as well.

skydhash•7m ago
My preferred definition of software engineering is found in the first chapter of Modern Software Engineering by David Farley

  Software engineering is the application of an empirical, scientific approach to finding efficient, economic solutions to practical problems in software.
As for the practitioner, he said that they:

  …must become experts at learning and experts at managing complexity
For the learning part, that means

  Iteration
  Feedback
  Incrementalism
  Experimentation
  Empiricism
For the complexity part, that means

  Modularity
  Cohesion
  Separation of Concerns
  Abstraction
  Loose Coupling
Anyone that advocates for agentic engineering has been very silent about the above points. Even for the very first definition, it seems that we’re no longer seeking to solve practical problems, nor proposing economical solutions for them.
danieltanfh95•39m ago
Agentic engineering is working from documentation -> code and automating the translation process via agents. This is distinct from the waterfall process which describes the program, but not the code itself, and waterfall documentation cannot be translated directly to code. Agent plans and session have way more context and details that are not captured in waterfall due to differences in scope.
mmastrac•37m ago
After three months of seeing what agentic engineering produces first-hand, I think there's going to be a pretty big correction.

Not saying that AI doesn't have a place, and that models aren't getting better, but there is a seriously delusional state in this industry right now..

iainctduncan•17m ago
And we haven't even started to see the security ramifications... my money is on the black hats in this race.
jbethune•34m ago
I think there is a meaningful distinction here. It's true that writing code has never been the sole work of a software engineer. However there is a qualitative difference between an engineer producing the code themselves and an engineer managing code generated by an LLM. When he writes there is "so much stuff" for humans to do outside of writing code I generally agree and would sum it up with one word: Accountability. Humans have to be accountable for that code in a lot of ways because ultimately accountability is something AI agents generally lack.
neonbrain•29m ago
The term feels broken when adhering to standard naming conventions, such as Mechanical Engineering or Electrical Engineering, where "Agentic Engineering" would logically refer to the engineering of agents
ares623•27m ago
Agentic Management doesn't have quite the same ring to it.
pamelafox•25m ago
I think “agent engineering” could refer to the latter, if a distinction needs to be made. I do get what you’re saying, but when I heard the term, I personally understood its meaning.
simonw•20m ago
Yeah, Armin Ronacher has been calling it "agentic coding" which does at least make it clear that it's not a general engineering thing, but specifically a code related thing.
pamelafox•26m ago
I’ve been using the term “agentic coding” more often, because I am always shy to claim that our field rises to the level of the engineers that build bridges and rockets. I’m happy to use “agentic engineering” however, and if Simon coins it, it just might stick. :) Thanks for sharing your best practices, Simon!
simonw•17m ago
I decided to go with it after z.AI used it in their GLM-5 announcement: https://z.ai/blog/glm-5 - I figured if the Chinese AI labs have picked it up that's a good sign it's broken out.

“It’s not vibe coding, it’s agentic engineering”

From Kai Lentit’s most recent video: https://youtu.be/xE9W9Ghe4Jk?t=260

simonw•21m ago
Thanks for the reminder, I should add a note about vibe coding to this piece.
jdlyga•17m ago
Sure, you could argue it's like writing code that gets optimized by the compiler for whatever CPU architecture you're using. But the main difference between layers of abstraction and agentic development is the "fuzzyness" of it. It's not deterministic. It's a lot more like managing a person.
techpression•13m ago
I mean agents as concept has been around since the 70s, we’ve added LLMs as an interface, but the concept (take input, loop over tools or other instructions, generate output) are very very old.

Claude gave a spot on description a few months back,

The honest framing would be: “We finally have a reasoning module flexible enough to make the old agent architectures practical for general-purpose tasks.” But that doesn’t generate VC funding or Twitter engagement, so instead we get breathless announcements about “agentic AI” as if the concept just landed from space.

stainlu•10m ago
The question of when you should not use it is more interesting than the naming debate. Agentic coding works well when the solution space is constrained and verification is cheap: existing tests cover the behavior, the output format is clear, and you can tell whether the result is correct by inspection. CRUD endpoints, data transformations, boilerplate integration code.

Where it breaks down is any task where you discover the requirements during implementation. Most hard engineering problems are like this -- you start building, realize the data model is wrong, reshape the abstraction, and iterate. An agent can execute your architecture, but it can't tell you your architecture is the wrong one. That judgment still requires someone who understands the domain deeply enough to notice when the code is solving the wrong problem correctly.

The name matters less than recognizing this boundary. Call it agentic engineering or agentic coding, the skill is knowing which tasks to hand to the agent and which to think through yourself first.
