Uff, I've tried stuff like these in my prompts, and the results are never good, I much prefer the agent to prompt me upfront to resolve that before it "attempts" whatever it wants, kind of surprised to see that they added that
Otherwise, the intent gets lost somewhere in the chat transcript.
Edit: forgot "don't assume"
I try to explicitly request Claude to ask me follow-up questions, especially multiple-choice ones (it explains possible paths nicely), but if I don't, or when it decides to ignore the instructions (which happens a lot), the results are either bad... or plain dangerous.
I've found that Google AI Mode & Gemini are pretty good at "figuring it out". My queries are oft times just keywords.
Edit: That said, it's entirely possible that large and sophisticated LLMs can invent some pretty bizarre but technically possible interpretations, so maybe this is to curb that tendency.
To me too, if something is ambigious or unclear when I'm getting something to do from someone, I need to ask them to clarify, anything else be borderline insane in my world.
But I know so many people whose approach is basically "Well, you didn't clearly state/say X so clearly that was up to me to interpret however I wanted, usually the easiest/shortest way for me", which is exactly how LLMs seem to take prompts with ambigiouity too, unless you strongly prompt them to not "reasonable attempt now without asking questions".
When I task my primary agent with anything, it has to launch the Socratic agent, give it an overview of what are we working on, what our goals are and what it plans to do.
This works better than any thinking tokens for me so far. It usually gets the model to write almost perfectly balanced plan that is neither over, nor under engineered.
—Claude Code: FLIPS THE SWITCH, does not answer the question.
Claude does that in React, constantly starting a wrong refactor. I’ve been using Claude for 4 weeks only, but for the last 10 days I’m getting anger issues at the new nerfing.
Seems like a good idea. Don't think I've ever had any of those follow up suggestions from a chatbot be actually useful to me
And of course all conversations now have to compact 80 tokens earlier, and are marginally worse (since results get worse the more stuff is in the context)
Because it's a waste of my money to check whether my Object Pascal compiler doesn't develop eating disorders, on every turn.
At some point you just have to accept that llm's, like people, make mistakes, and that's ok!
It's not a niche issue at all. 29 million people in the US are struggling with an eating disorder [1].
> This single paragraph is going to legitimately cost anthropic at least 4, maybe 5 digits.
It's 59 out of 3,791 words total in the system prompt. That's 1.48%. Relax.
It should go without saying, but Anthropic has the usage data; they must be seeing a significant increase in the number of times eating disorders come up in conversations with Claude. I'm sure Anthropic takes what goes into the system prompt very seriously.

The trajectory is troubling. Eating disorder prevalence has more than doubled globally since 2000, with a 124% increase according to World Health Organization data. The United States has seen similar trends, with hospitalization rates climbing steadily year over year.

Except that's not the way many everyday users view LLM's. The carwash prompt went viral because it showed the LLM making a blatant mistake, and many seem to have found this genuinely surprising.
So spending $50M to fund a team to weed out "food for crazies" becomes a no-brainer.
Yes, the companies providing these products are sued a lot and are heavily regulated, too.
We let people buy kitchen knives. But because the kitchen knife companies don't have billions of dollars, we don't go after them.
We go after the LLM that might have given someone bad diet advice or made them feel sad.
Nevermind the huge marketing budget spent on making people feel inadequate, ugly, old, etc. That does way more harm than tricking an LLM into telling you you can cook with glue.
It's a particularly sensitive issue so they are just probably being cautious.
This era of locked hyperscaler dominance needs to end.
If a third tier LLM company made their weights available and they were within 80% of Opus, and they forced you to use their platform to deploy or license if you ran elsewhere, I'd be fine with that. As long as you can access and download the full raw weights and lobotomize as you see fit.
They don’t reliably have the judgment to pause and proceed carefully if a delicate topic comes up. Hence these bandaids in the system prompt.
Letting the system improve over time is fine. System prompt is an inefficient place to do it, buts it's just a patch until the model can be updated.
I am strongly opinionated against this. I use Claude in some low-level projects where these answers are saving me from making really silly things, as well as serving as learning material along the way.
This should not be Anthropic's hardcoded choice to make. It should be an option, building the system prompt modularily.
For low level I recommend to run tests as early as you can and verify whatever information you got when you learn, build a fundamental understanding
The malware paranoia is so strong that my company has had to temporarily block use of 4.7 on our IDE of choice, as the model was behaving in a concerningly unaligned way, as well as spending large amounts of token budget contemplating whether any particular code or task was related to malware development (we are a relatively boring financial services entity - the jokes write themselves).
In one case I actually encountered a situation where I felt that the model was deliberately failing execute a particular task, and when queried the tool output that it was trying to abide by directives about malware. I know that model introspection reporting is of poor quality and unreliable, but in this specific case I did not 'hint' it in any way. This feels qualitatively like Claude Golden Gate Bridge territory, hence my earlier contemplation on steering vectors. I've been many other people online complaining about the malware paranoia too, especially on reddit, so I don't think it's just me!
Of course it's also been noted that this seems to be a new base model, so the change could certainly be in the model itself.
(URL is to diff since 2.1.98 which seems to be the version that preceded the first reference to Opus 4.7)
I feel like this explains about a quarter to half of my token burn. It was never really clear to me whether tool calls in an agent session would keep the context hot or whether I would have to pay the entire context loading penalty after each call; from my perspective it's one request. I have Claude routinely do large numbers of sequential tool calls, or have long running processes with fairly large context windows. Ouch.
> The Anthropic prompt cache has a 5-minute TTL. Sleeping past 300 seconds means the next wake-up reads your full conversation context uncached — slower and more expensive. So the natural breakpoints:
> - *Under 5 minutes (60s–270s)*: cache stays warm. Right for active work — checking a build, polling for state that's about to change, watching a process you just started.
> - *5 minutes to 1 hour (300s–3600s)*: pay the cache miss. Right when there's no point checking sooner — waiting on something that takes minutes to change, or genuinely idle.
> *Don't pick 300s.* It's the worst-of-both: you pay the cache miss without amortizing it. If you're tempted to "wait 5 minutes," either drop to 270s (stay in cache) or commit to 1200s+ (one cache miss buys a much longer wait). Don't think in round-number minutes — think in cache windows.
> For idle ticks with no specific signal to watch, default to *1200s–1800s* (20–30 min). The loop checks back, you don't burn cache 12× per hour for nothing, and the user can always interrupt if they need you sooner.
> Think about what you're actually waiting for, not just "how long should I sleep." If you kicked off an 8-minute build, sleeping 60s burns the cache 8 times before it finishes — sleep ~270s twice instead.
> The runtime clamps to [60, 3600], so you don't need to clamp yourself.
Definitely not clear if you're only used to the subscription plan that every single interaction triggers a full context load. It's all one session session to most people. So long as they keep replying quickly, or queue up a long arc of work, then there's probably a expectation that you wouldn't incur that much context loading cost. But this suggests that's not at all true.
No I am not joking. Every time you install something, there is a risk you clicked a wrong page with the absolute same design.
Every statement they make, hell even the models themselves are going to be doing this theater of "Ooooh scary uber h4xx0r AI, you can only beat it if you use our Super Giga Pro 40x Plan!!". In a month or two they'll move onto some other thing as they always do.
It gets pretty efficiently cached, but does eat the context window and RAM.
Also full of "can" and "should" phrases: feels both passive and subjunctive as wishes, vs strict commands (I guess these are better termed “modals”, but not an expert)
It must be that they are training very deeply the sense of identity in to the model as Claude. Which makes me wonder how it then works when it is asked to assume a different identity - "You are Bob, a plumber who specialises in advising design of water systems for hospitals". Now what? Is it confused? Is it still going to think all the verbiage about what "Claude" does applies?
class Claude {}
Claude anthropicInstance = new Claude();
anthropicInstance.greet();
So I'm guessing they want none of the model users (webui + API) to be able to do those things, rather than not being able to do that just in the webui. The changes mentioned in the submission is just for claude.ai AFAIK, not API users, so the "disordered eating" stuff will only be prevented when API users would prompt against it in their system prompts, but not required.
edit: to be fair Anthropic should be giving money back for sessions terminated this way.
I asked it for one and it told me to file a Github issue.
Which I interpreted as "fuck off".
My concern is these models revert all medical, scientific and personal inquiry to the norm and averages of whats socially acceptable. That's very anti-scientific in my opinion and feels dystopian.
