Prompt engineering and now ”context engineering” are really the poor man’s engineering work when you’re subject to model iterations and cannot control any of the stochasticity of the models… what we need is better science to understand how to control large model’s output, not more LinkedIn AI influencers
_Algernon_•6mo ago
Reads like an alchemist trying to write about how to create gold.
behnamoh•6mo ago
Great, yet another hyped up word to keep the AI hype going...

I respect Karpathy, but I can’t shake the feeling that recently has been doing more damage than good to the AI community. First he came up with “vibecoding“ and now this one. What we need is better engineering approaches to build AI systems, not buzzy marketing words that only benefit AI companies.

saturatedfat•6mo ago
writing an essay on this if you'd be interested in reading a rough draft. i believe this very strongly and i think it's the UX that got us here and it's UX that'll take us out.
9dev•6mo ago
Honestly, I don’t think it’s about AI even. The world has become so cynical, that’s just how people make business now. If it wasn’t context engineering, it’d be professional Watermelonism.
cavisne•6mo ago
Vibecoding is an excellent term, its communicates that the output and process is not entirely serious. I think without this term we would have even more PM types announcing that programming is dead and you just need a business person with some prompts copied off linkedin.

I think this gives room for non technical people to vibecode prototypes, knowing that the output will eventually go off the rails without technical understanding.

I guess codepooping just didn't have the same ring

"Include relevant files directly, instead of letting the agent immediately grep your codebase, to save ninety seconds."
apwell23•6mo ago
this is too convoluted and has no proof why it should be done this way
gavinh•6mo ago
This is exhausting.
jalapenos•6mo ago
You sir are a tiredness engineer
thorum•6mo ago
The interesting part of context engineering (the actual engineering part) is figuring out how to gather the information the LLM needs to do a task correctly from your system. For example, the secret sauce of GitHub Copilot is how it decides what parts of your codebase to show the LLM. This is surprisingly hard when you need something other than simple RAG. In many cases the data source you need doesn’t exist and you have to build it.

The prompt engineering side of the problem (how you structure your prompt) is trivial by comparison and will become less and less relevant as frontier models improve.

jimby•6mo ago
One thing I've noticed is llms are much better at outputting tabular data than json objects, especially for lists
zmmmmm•6mo ago
It seems endemic to software to me that people constantly want to brand things as "engineering" that aren't. They always want to call it engineering because it sounds better but they don't want to do nearly anything associated with engineering - rigorous process control, systematic documentation, specification of tolerances, resource usage etc etc.

What's described here is mostly a list of barely disguised tips, tricks and heuristics. It's all fine until someone wants to put it in production and suddenly a "real" engineer has to take over and do the actual engineering.

(and yes, I'm old - and grumpy!)

bachmeier•6mo ago
Anyone believing software engineering is a legitimate term should also accept context engineering as a legitimate term. Wikipedia's definition of engineering includes "The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination" and context engineering as the term is used definitely qualifies if software engineering does.
jjmarr•6mo ago
Licensed engineers accept responsibility for those structures/machines/etc when they physically harm or kill others. Like lawyers or doctors being sued for malpractice.

A typical person does not understand scientific principles and cannot validate whether a bridge is safe before using it. An engineer that approves a bridge can be held liable when that bridge fails, even if they had orders from their boss or company.

If you're not prepared to accept personal liability when your code kills someone or causes a disaster, you shouldn't try to be an engineer.

I live in a country (Canada) where software engineering is legally considered engineering and that's what officially distinguishes a "software engineer" from a "software developer". In practice, I rarely see the rule followed.

ekianjo•6mo ago
Legal responsibility and the matter of engineering are two different and unrelated things. You can do engineering without a license.
hinkley•6mo ago
That's just called 'building'.

Unless you're actively attacking a castle.

rester324•6mo ago
Yeah, and wikipedia also states that engineering is a decision making process (often iterative) in which the engineering sciences, basic sciences and mathematics are applied to convert resources optimally to meet a stated objective.

So which scientific principles do context engineering apply?

There is none. So yeah. It's not engineering at all.

zmmmmm•6mo ago
I accept most of your point - that engineering has a much broader definition than what I'm alluding to. But the part I'll quibble with is the extent to which there are "scientific principles" involved here. This seems almost entirely empirical to me.
wasabi991011•6mo ago
I don't believe it was empirically checked either tbh, just anecdata
d_tr•6mo ago
"Context Architect" is probably going to be a job title soon. Stay tuned!
jalapenos•6mo ago
Followed by "Chief Context Executive"
jalapenos•6mo ago
Journalist - word engineer

Doctor - body engineer

Lawyer - court engineer

Plumber - pipe engineer

Gardener - plant engineer

Politician - lie engineer

Psychotherapist - feelings engineer

Criminal - crime engineer

Chef - food engineer

Baby - cry engineer

Dog - woof engineer

You see, we're all engineers.

adidoit•6mo ago
The shift from prompt engineering to context engineering is a massive tailwind for the "GenAI certification industry™"
xnx•6mo ago
Sounds like a lot of superstition if there aren't the examples to show that such a complicated approach beats a less complicated ones.
spicyusername•6mo ago
As others have mentioned, I wish we'd stop borrowing the word engineering for everything.

This domain is so far from real engineering it's almost embarrassing.

Just asked CC to create a work tree and branch. (Space was a typo) What did it do? Just a branch…

You cant trust LLMs for 100%, constant supervision is needed
