Opus 5 is driving people nuts. Anthropic gave the fix
385 segments
There's a widespread problem plaguing
Claude users recently, specifically on
Opus 5, because its replies [music] tend
to be confusingly long, packed with all
too possible nonsense, and it's becoming
more and more jargon dense. The good
news is that Anthropic already shared a
fix for this. It's super easy, and the
principle behind it makes your setup
faster and cheaper, and it lets you
finally understand what the heck your
agents are actually saying. And by the
end, I'll hand you a resource that
solves all of this automatically just by
sending it to Claude. Let's dive into
it. So, if you've been using Opus 5
heavily the past few days, you may have
noticed two specific problems with it.
The first one's the jargon problem,
which is its tendency to use technical
terms or acronyms much more versus
earlier models, which makes it much
harder to understand and work with. Just
to give you one simple example, and this
is probably not the worst of it. If you
ask a simple question to Opus 5 like
this, where I said our CRM dashboard
says open rate is 32%, and I said from a
conversation with a peer, we discussed
how open rates are basically fake now.
So, I ask it what does that mean, and
should I care? And it did give us a
proper explanation here, but it seems to
always default to being more
comprehensive and more technical than
most people would probably want it to.
And you can see its tendency to assume
that you know every single jargon in the
field as well. Like for example, here
it's saying every Apple Mail recipient
with MPP on registers as an open. And it
also tends to use a lot of technical
jargon like send time optimization, geo
data, or device data derived from opens,
MPP masks IP, and reports a generic
device. So, all of this is corrupted.
So, you can see what I mean, right? And
like I said, that example was probably
not the worst of it, because I first
became aware that this is sort of a
widespread problem when I saw this tweet
by Peter Levels, who's pretty popular in
the in the hacking space, where he
shared this snippet of an article that
made the rounds around X recently. And I
can probably show the actual article
just to give credit where it's due. So,
this was written by Niklas Kron, if I'm
ever pronouncing it correctly. And I
think he summarized the problem really
well here, where he's saying that
reading AI output today is extra effort.
You can pretty much do it, but it is
extra effort. It's verbose, it
frequently contains all too plausible
nonsense, and is increasingly jargon
dense. And then he says that he recently
got this sentence from Claude that even
I don't know what this means really. And
then the second, but related problem is
the wall of text issue. So if we go back
to our example here, you probably
experienced the same thing where you ask
it a simple question and then it goes
into a full-blown essay and gives you a
wall of text as an answer. And for most
cases, there's multiple issues with
that, right? Because it wastes your time
because you need to understand and read
through this whole thing in order to get
to the point. And secondly, there is
also a corresponding cost for tokens
because the longer it's output to you,
the more tokens that Claude is
consuming. And so if you have this same
problem with Opus 5 as well, which a lot
of people seem to be using as their
default, then you're in the right place
because today I'll be showing you the
two solutions for those two unique
problems. And by the way, if you want to
learn how to build and sell AI systems
that businesses actually pay for, then
that's pretty much all we do over at the
Robonuggets community where not only do
you get access to the Claude Living
Masterclass, which we update every week
and takes you from zero to mastery with
the latest on AI, but you also get
access to our Agents as a Service
course, which walks you through how to
actually get paid for all these AI
skills that you are learning. You also
get to be part of a genuinely great
community of AI builders. In fact, you
can see just some of the recent wins our
members are getting from the program
right here. So if you want to start
earning from AI, then check that just in
the pinned comment below. Now back to
the video. So let's start with the
jargon problem. And the good news about
this is that Anthropic's team actually
talked about how to fix this one issue.
And that fix is courtesy of Lidia, who
is a member of technical staff at
Anthropic. And essentially, it all has
to do with this configuration in Claude
Code that's called the output style. And
the output style is simply just that. It
is the style by which Claude Code
provides its output to you or how it
talks to you. And I'll just show you
where to find it, at least in the
terminal view, but I'll show how to do
it in the desktop app as well if in case
you're more comfortable there. But here
in the terminal, if you have Claude
Claude open, you can slash config, which
brings up all your settings. And if you
find output style here, and if I click
on enter, what you would most likely
find is that your Claude is set to the
default output style, which is that
verbose jargony output that Opus 5
usually defaults to. You have other
options here like proactive,
explanatory, and learning that Claude
Claude ships with by default. But you
can see that I have a fifth one here
that I added as a custom called ELI5.
And this ELI5 is the fix that Lydia was
talking about here. And in case you're
curious, ELI5 simply stands for explain
like I'm 5. It is a popular subreddit.
And so the reason why that acronym works
for a lot of models, including Opus 5,
is because they've been trained with the
entirety of the internet, including that
subreddit. And if you're curious, this
is what that subreddit is. And there's
like thousands of posts in here asking
questions in the ELI5 format. And you
can be sure that these models have
scraped this whole thing in order to
understand how people respond to these
questions. But the core principle of it
is if you want things to be simple to
understand, then this ELI5 is one way to
do it. Now, obviously, you don't have to
adopt the exact verbiage that Lydia has
here. For example, one thing that I
added in my output style personally is
this tip from Andrew that I found where
he asked Claude to only report to him in
this ASD STE 100 simplified technical
English. So what is that? Well, in a
nutshell, that's essentially a
controlled language standard that uses a
more restricted dictionary. So a list of
words that are much easier to
understand. So it avoids jargon, it
avoids a lot of those technical
vagueness. And at least from what I
found personally, and for a lot of
people it seems, that standard seems to
help a lot in terms of just making
talking to your agents much easier and
much more seamless. So how do you now
apply this fix and actually change your
output style so you can test it out?
Well, what you can do is to just copy
this prompt or take a screenshot of it
and send it to your Claude Claude. And
what you're saying here is simply to set
your output style to the one below,
which is this whole snippet from Lidia
with that addition of the ASDSE100.
And then the important part here is
direction to save it in your output
styles folder, which obviously depending
on your workspace, that location of that
folder may be different. But the good
news is Claude Code can probably find
that for you. At least for me, this is
where it put that markdown file. And
within this markdown file is just this
piece of text. And then the second thing
that this prompt will do is to just set
this output style for ELI5 in the
appropriate settings files. And you can
see for me, because I already have it
set, that is what Claude also told me,
where it created that style file for me
that ELI5.md. And it also updated the
relevant settings. And the best way for
you to check is to just open up a new
session and ask what output style it's
using now just to confirm. And if you
need to make any changes to it, then you
can just tell that to Claude and it will
update this output style for you. Now,
you may be asking why it's important to
put these rules in the output style
instead of something like the Claude.
md. And the truth of the matter is that
you can actually put these rules into
Claude.md, but it just isn't as
effective. And if you're curious, it has
to do with two things. One is the
strength of the placement with regard to
the output style, because if you notice,
what we changed earlier is the actual
settings for Claude Code. So, it's
written into the core system prompt of
your Claude Code instance. And then more
importantly, at least I would think, is
that under the hood what Claude Code
actually does is it auto injects these
sort of nudges, these reminders like
stick to your output style even midway
through out your session. So, if you
were to show that visually, your
Claude.md that does get preloaded into
every session that you start, but only
at the top, right? But the great thing
about putting this rule into your output
style is that it becomes part of the
core system prompt, number one, and
number two, throughout your session,
Claude Code actually gets reminded about
this rule so that it follows it more
consistently and religiously. And just
to give an example of that same question
that we asked it, if you read through
this, it's much more legible now, at
least in my view. It leads with the key
answer, where it's saying that that open
rate is not all real people. And then it
tells the clear story here of why that
is, and then ends with this conclusion
that anyone can understand. Now, that
fixes the jargon problem. Now, let's go
to the second issue, which is this wall
of text that you usually get from Opus
5. And for a lot [snorts] of use cases,
especially knowledge work or production
code, the tricky part about this problem
is that you do sometimes need long
pieces of text in order to get a lot of
the detail that you need. And so this is
why I generally I won't advise people to
put the wall of text fix right in the
output style. And so what I would
generally recommend is to just use a
skill when you need that wall of text to
be shorter. And in our community, I
always advise people to make their own
skills because each of our work is
different. But let me give you some
ideas, and I'll also share how I do it
personally. One really interesting skill
that I found is this one called {slash}
bro. And it's probably one of the
shortest, but really useful skill that
you can add to your arsenal because it
is only one line. So its sole purpose,
whenever you invoke it, is for your
agent to restate the last message in
plain human language with zero jargon.
And so if we go back to this wall of
text, and you can see here I just used
that skill, {slash} bro. When it rewrote
their response, it's saying here, "Okay,
so basically that 32% never meant 32 out
of 100 people actually read this. And
here's how it actually works." So I'm
not going to read the whole response
here, but you can see just how much more
understandable and better it is versus
what we started, right? Another example
of a skill that I found is this one from
Matt Pocock. It's called wait, what? So
again, it's a very short skill. It says,
"I don't understand where you've got to
here. Repitch that and give a little bit
of context." And this is what I'm saying
where you need to create your own skills
because you can see from Matt's
workspace here, he probably has this
context.md that he uses a lot. You may
not have that. So what you can do is to
take a screenshot of this or copy this
skill and just ask Claude to personalize
it for your own setup. Now, what I tend
to do personally, in conjunction with
{slash} bro, since you can see sometimes
Opus 5 still defaults to a wall of text
if it doesn't know how long you want the
response to be. Is I use this skill of
mine called /quick, where I just declare
a number, in this case three, and it
gives me just three points in sequence
of what it thinks is the most important
takeaway from that whole essay that it
wrote. And just to show you what that
skill looks like, I think it's this one.
Yeah, so you can see this is the /quick
skill. And you can see just in its
current state, it just has rules on when
to use it when I don't declare a number,
when I declare a number. And apparently
there's now, how many? Two modes here
that probably naturally arose since I
use this skill a lot, and I also ask
Claude to tweak it depending on our
conversation. But that is one idea by
which you can cut that wall of text into
more bite-size chunks. But like I
mentioned, it's probably better for you
to just get these ideas for skills and
create them yourself as well, depending
on your type of work. Now, what I talked
about just now are pretty simple fixes,
but if you take a step back, there's
actually a larger takeaway to this whole
thing. Because interestingly, and if you
remember, Opus 5 is actually the best in
terms of a lot of benchmarks that we see
online, including this one from
artificialanalysis.ai,
where it is leading at the moment. And
so, the first key takeaway here is that
even though benchmarks show the raw
intelligence of these models, user
experience can sometimes differ. So,
it's sort of like if you bought a
computer with the highest specs
available, but then you actually find
that you prefer your older computer just
because of maybe some unique features
that that old model have. So, it's quite
similar to AI models also is what I'm
finding. And so, what you should realize
here is that let's say a year or two
down the line where you have Opus 7 or
Opus 10 already, if those future more
powerful models have the same issue as
well, the good news about it is that
these AI models are very malleable, and
you can just tweak your AgentiC
Operating System, or essentially the way
that you talk to these agents, through
these same solutions that we talked
about, and that will just provide a much
better experience for you when you work
with agentic AI. And so just remember
that you can always direct these models
with your preferred output style as well
as these skills, which are essentially
shortcuts. And just to make it easy,
everything that I talked about in this
lesson in this video, I just put it all
in this eight-page PDF, which you can
probably just send to your cloud code
and just pick out the prompts and the
styles and the skills that you would
need and just tweak them to whatever
your workspace needs. So you can just
find this whole thing down in the
description. I hope that was helpful and
as always appreciate you for making it
until the end because that helps me a
lot and I'll see you next time. Thanks.

This video addresses common issues with Claude Opus 5, specifically its tendency to provide overly long, jargon-heavy, and confusing responses. The presenter offers practical solutions to refine these outputs by adjusting the model's 'output style' configuration and creating custom 'skills' (shortcut commands). By implementing these settings, users can make their AI agents more efficient, cheaper to run, and easier to understand. The video also emphasizes that while powerful AI models like Opus 5 exist, user experience depends heavily on how these agents are configured through custom system prompts and interaction styles.
