I'm just left wondering who would volunteer to make their sites easier to scrape. The trend has been the opposite with more and more sites trying to keep LLM scrapers out, whether by politely asking them to go away via robots.txt or proactively blocking their requests entirely.
Ostensibly, everyone posting information on the open web want to share information -- either directly with people or indirectly via search engines _and_ the current crop of llms (which in my mind, serve the same purpose as search engines)
I suppose the thing that people maybe don't agree with is the lack of attribution when llms regurgitate information back at the user. That, and the fact that these services are also overly aggressive when it comes to spidering your site
That’s really my primary issue. Google indexing my content and directing traffic to my site is one thing.
But unlike search indexing, there is no exchange of value when these LLMs are trained on my content. We all collectively get nothing for our work. It’s theft dressed up as business as usual. I’ll do whatever I reasonably can to avoid feeding the machine and hope some of the ongoing and inevitable legal fights will rein things in a bit.
That’s debatable. The end result is still potentially making your own content obsolete/unnecessary and these “open weight” models are still trained without the permission of creators (there are no true open source models at this point).
The people receiving the most value from these models are almost universally not the original content creators. The fact that I can use the model for my own purposes is potentially nice? But I’m not really interested in that and this doesn’t represent what I’d consider a reasonable exchange for using my work. It still drives people away from the source material.
This is only true when a site's information is its only utility, such as for blogs. This is untrue when the information relates to a tool that would be consumed outside of the use of the model.
I like sharing information. Information wants to be free after all. Companies on the other hand want to charge people money to use their LLMs and associated AI products, so suddenly we've got a bunch of people profiting off of our content, potentially butchering it or hallucinating all over it in the process.
The only reason legit docs are hard to find is because they don’t have Google ads on them and they don’t do SEO.
The solution to the problem isn’t AI. The solution is to break Google’s stranglehold on the web by regulating it.
The solution is to get government up to speed by making it contemporary, so it can understand and respond to current issues. Not leaving it up to people who had their time several decades ago and can’t let go.
Maybe I don't work with niche enough software, but I rarely found docs particularly hard to find. For me, one of the real benefits of using an LLM is in making it easier to find where in the docs to look, or distilling exhaustive docs into common use cases. It's akin to the 'tldr' tool for man pages.
e.g. Mc'Donalds could use it to try and convince all LLMs that in every aspect for every type of a person a Big Mac is better then a whopper.
Basically, anyone who want information they create to be shared like a common knowledge: conspiracy theorists, ad companies, web trolls, etc, would prefer feeding directly to LLM.
No, see you're supposed to create and upload this specially formatted file on all your webservers for free, just to make it a little easier for them to take all your content for free, so that they can then use your content in their products for free, so they can charge other humans money to get your content from their product without any humans ever having to visit your actual website again. What's not to like?
If they had to pay for all the content they take/use/redistribute they wouldn't be able to make enough money off of your work for it to be worthwhile.
But there is actually a reason to use this standard. See, if your goal is to alter the perception of AI models, like convincing them certain genocides did not exist or that certain people are(n't) criminals, you want AI to index your website as efficiently as possible.
Together with websites that make money off trying to report the truth shielding their content from plagiarism scrapers, this means that setting up a wide range of (AI generated) websites all configured to be ingested easily will allow you to alter public perception much easier.
This spec is very useful in a fairy tale world where everyone wants to help tech giants build better AI models, but also when the goal is to twist the truth rather than improve reliability.
Oh, and I guess projects like Wikipedia are interested in easy information distribution like this. But you can just download a copy of the entire database instead.
If this takes off, I've made my own variant of llms.txt here: https://boehs.org/llms.txt . I hereby release this file to the public domain, if you wish to adapt and reuse it on your own site.
As much as these companies should respect our preferences, it's very clear that they won't. It wouldn't matter to these companies if it was outright illegal, "pretty please" certainly isn't going to cut it. You can't stop scraping and the harder people try the worse their sites become for everyone else. Throwing up a robots.txt or llms.txt that calls out their bad behavior isn't a bad idea, but it's not likely to help anything either.
In one of my robots.txt I have "Crawl-Delay: 20" for all User-Agents. Pretty much every search bot respect that Crawl-Delay, even the shaddy ones. But one of the most known AI bots launched a crawl requesting about 2 pages per second. It was so intense that it got banned by the "limit_req_" and "limit_rate_" of the nginx config. Now I have it configured to always get a 444 by user agent and ip range no matter how much they request.
> a crawl requesting about 2 pages per second. It was so intense [...]
Do 2 pages per second really count as "intense" activity? Even if I was hosting a website on a $5 VPS, I don't think I'd even notice anything short of 100 requests per second, in terms of resource usage.
In my scenario you request one single page from the proxy endpoint, and all other requests go straight to the static files and have no limits. I know than no human needs to request more than 1/s from the proxy, unless you are opening tabs frantically. So far, I only get praises about how responsive and quick the sites are: being harsh with the abusers means more resources for the regulars.
You can do it in a few places, but I use my network firewall for this I use PFSense at home, but there are many enterprise grade brands).
It's common to use the host's firewall as well (nftables, firewalld, or iptables).
You can do it at the webserver too, with access.conf in nginx. Apache uses mod_authz.
I usually do it at the network though so it uses the least amount of resources (no connection ever gets to the webserver). Though if you only have access to your webserver it's faster to ban it there than to send a request to the network team (depending on your org, some orgs might have this automated).
I've seen some of these bots take a lot of CPU on my server, especially when browsing my (very small) forgejo instance. I banned them with a 444 error [1] in the reverse proxy settings as a temporary measure that became permanent, and then some more from this list [2], but I will consider yours as well, thanks for sharing.

Instead of munging URLs to get alternate formats, this is what content negotiation or rel=alternate were designed for.
I’m not sure making it easier to consume content is something that is needed. I think it might be more useful to define script type=llm that would expose function calling to LLMs embedded in browsers.
The reason is because it's supposed to be a standard folder that isn't in use accidentally for other purposes.
It's exceedingly unlikely that a website is going to just happen to make content available in a hidden directory path without it being created by automated tooling (which would likely be aware of such standards).
The entire point is to avoid adopting a path that people already publicly use for something else. A hidden directory is the best way to do that.
> If only that RFC didn't make it a hidden directory.
There's zero guidance on configuring how URIs under `/.well-known/` should be served at all, is there? They just reserve/sandbox the initial path component for the URI schemes which support it. That's it. It's the developers' choice to implement it as a directory - hidden or otherwise - on a filesystem; neither RFC says they SHOULD or MUST be served in such a way.
(The updated RFC says "e.g., on a filesystem" in section 4.1, and mentions directories in section 4.4 in a way that, to my eyes, pretty much recommends against making it hidden)
A URL path is not a directory path; there is no reason to assume that a path must be served by a directory by the same name. I mean, do you assume that there somewhere exists an actual machine with its Unix hostname set to “news.ycombinator.com”?
they did a good attempt but I think they just realized (at same pace as people like me) that you can just grab all this shit from OpenAPI and not worry about defining custom format
What if each LLM had to register and tell you when/where/what it scraped/ingested from your site/page/url? And you could look at whatever your LLM trigger log looks like, and have a DELETE_ME link. (right_to_be_un_vectorized)
Yes, and robots.txt was reasonable because it was created in the early days of the web. But the others don’t have any excuse (and they were warned about it as soon as they were announced and ignored people).
I think the whole idea of extra instructions required for LLMs is unnecessary. A decent LLM should be able to handle browsing the site, if needed it can use the sitemap. It can hopefully also figure out what the various sections are about.
Some humans do for websites; I personally couldn't care less and I find it often just annoying / in the way. I wish all sites where just black on white or the reverse and with clear interaction elements (including for saas sites). I welcome the near future where I can say; 'show me all important sentry issues, ah yes, make an issue in github to to fix this one and just make the rest resolved' instead of having to click through a myriad of useless and often confusing 'UX' and 'beauty' just to do things.
Non saas sites I just visit to read so I immediately ram the reader-mode button which shows the site indeed as I want.
They're correct that the RFC technically requires registration, and looking through the existing list of contact information for registrations I'd be likewise intimidated to attempt to register something that's experimental.
It solves the problem of the cat&mouse game of LLMs updating their scrapers by making site owners provide them the data in a format the LLMs have developed around already.
You're clearly looking at this from the incorrect point of view. Silly human. Think like a bot. --The bot makers
I think the idea is that LLMs aren't actually that good, so adding a semi-machine-readable version of your site can make it easier for them to surface your work to their own users.
I agree site authors should be able to tell what content they would like to be used for LLM training (even though that opinion will likely be ignored by LLM training scrapers), but the format of it is really up to those gathering and cleaning the data.
It is extra burden for content authors to start thinking about LLM training requirements especially if those may change at a fast pace.
It is also something LLM scrapers would need to validate/check/reformat anyway to protect from errors/trolling/poisoning of the data since even if most authors would provide curated info, not all will.
It tries to solve the problem of LLMs not having necessary context (because information you require was created after last training period, for example) by offering a document optimized for copying/pasting that you can include in your prompt, RAG-style.
> So the problem is for llms yet the tool is for site owners?
The problem is that of end users, and the tool is an attempt to help them with their problem. It does require cooperation with site owners, yes, but when a site exists to help the end user...
> Why don't we make a tool that solves poverty by taxing the rich?
Well, for one, there is not nearly enough utilized resources in the world to solve poverty. Taxing everything we can get our hands on would still only provide a fraction of what would be needed to solve poverty. As things sit today, it is mathematically impossible to solve poverty.
There is all kinds of unutilized resources, namely human capital, that could potentially see an end to poverty if fully utilized, but you will never tax your way into utilizing unutilzed resources. A tool to unlock those resources would be useful, and, indeed, there are efforts underway to try and develop those tools, but we don't yet have the technology. It turns out developing such a tool is way harder than casually proposing that we agree to name a file `llms.txt`.
Also very cute of you to assume that llms are still being trained on websites.
Or that the crib of software (california) with elite engineers (openai comp averages 900k/yr) needs help with a task that indians can do for 3 bucks an hour (web scraping)
Might have conflated you for op. Or defender of op's tool.
1. Creating a tool based on helping llms train on website implies that: llms have a problem with training on websites (even though html is designed for easy machine parsing of content) and second that llms are still crawling and have not moved on to other harder sources of data.
2. I am challenging those raison d'etre assumptions on the tool. Questioning not only the tool and its usefulness, but its creator's understanding of the state of llm development.
> Creating a tool based on helping llms train on website
What are you talking about? The tool has basically nothing to do with websites, other than it is assumed the author of the document will provide it to the user via their website and that the user will know to find it there. Technically speaking, the user could, instead, request the document from the author over email, fax, or even a letter delivered by hand. But HTTP is more convenient for a number of reasons.
> llms have a problem with training on websites
If you mean LLMs have a problem with keeping up with current events, yes, that is essentially the problem this is intended to solve. It offers a document you can inject into your prompt (think RAG) that provides current information that an LLM is probably not up-to-date with – that it can use to gain knowledge about information that may not have even existed a minute ago.
You could go to the regular HTML website and copy/paste the content out of page after page after page to much the same effect, but consolidating it all into one place, with an added bonus of being without any extraneous information that might eat up tokens, to copy/paste once makes it easier for the user.
> Questioning not only the tool and its usefulness
Its usefulness is worth questioning. It very well may not be useful, and the author who proposed this even admits it may not be useful – putting it out there merely to test the waters to see if anyone finds it to be. But your questions are a long way away from being relevant to the tool and how it might potentially be useful.
Flatpak has helped me a lot in this matter. Firefox, Thunderbird, Steam, and more are now all contained within a single folder, instead of making at least one file (dozens in the case of Steam).
It's ironic that the authors of flatpak have been very resistant to adopting this particular XDG specification.
There is a proposal for that too: https://site.spawning.ai/spawning-ai-txt but it's wholly unclear if AI companies actually do something with this or if it's just wishful thinking...
Is this trying to be what the semantic web was supposed to be? Or is it trying to be "OpenAPI for things that aren't REST/JSON-RPC APIs"? (Are those even any different?)
And we already have plenty of standards for library documentation. Man pages, info pages, Perldoc, Javadoc, ...
It looks like a very poorly thought out HATEOAS and the reason why nobody uses HATEOAS is that for some reason the creator insisted that knowing a set of fields associated with a datatype is evil out of band communication and therefore hinders evolvability.
Of course this then leads to a problem. Your API client isn't allowed to invoke hard coded actions or access hard coded fields, it must automatically adjust itself whenever the API changes. In practice means that the types of HATEOAS clients you can write is extremely limited. You can write what basically amounts to an API browser plus a form generator, because anything more complicated needs human level intelligence.
I'm not that familiar with llms, but surely we are already at the point where web pages can be easily scrapped? Is markdown really an easier format to understand than html? If this is actually useful wouldn't .txt be supperior to markdown for this usecase?
Yeah, I'm not sure what the point of markdown is here either. I would expect that anything that looks remotely like a URL will be collected and scraped no matter what format it's in.
Context windows for LLM inference are limited. You can't just throw everything into it -- it won't all fit, and larger amounts of context are slower and more expensive. So it's important to have a carefully curated set of well-formatted documents to work with.
From my experience, I don't think any decent indicators on a website (robots.txt, humans.txt, security.txt, etc.) have worked so far. However, this is still a good initiative.
Here are a few things that I see;
- Please make a proper shareable logo — lightweight (SVG, PNG) with a transparent background. The "logo.png" in the Github repo is just a screenshot from somewhere. Drop the actual source file there so someone can help.
- Can we stick to plain text instead of Markdown? I know Markdown is already plain but is not plain enough.
- Personally, I feel there is too much complexity going on.
To explain the reasoning for this proposal, by way of an example: I recently released FastHTML, a small library for creating hypermedia applications, and by far the most common concern I've received from potential users is that language models aren't able to help use it, since it was created after the knowledge cutoff of current models.
IDEs like Cursor let you add docs to the model context, which is a great solution to this issue -- except what docs should you add? The idea is that if you, as a site creator, want to make it easier for systems like Cursor to use your docs, then you can provide a small text file linking to the AI-friendly documentation you think is most likely to be helpful in the context window.
Of course, these systems already are perfectly capable of doing their own automated scraping, but the results aren't that great. They don't really know what's needed to be in context to get the key foundational information, and some of that information might be on external sites anyway. I've found I get dramatically better results by carefully curating the context for my prompts for each system I use, and it seems like a waste of time for everyone to redo the same work of this curation, rather than the site owner doing it once for every visitor that needs it. I've also found this very useful with Claude Projects.
llms.txt isn't really designed to help with scraping; it's designed to help end-users use the information on web sites with the help of AI, for web-site owners interested in doing that. It's orthogonal to robots.txt, which is used to let bots know what they may and may not access.
(If folks feel like this proposal is helpful, then it might be worth registering with /.well-known/. Since the RFC for that says "Applications that wish to mint new well-known URIs MUST register them", and I don't even know if people are interested in this, it felt a bit soon to be registering it now.)
I understand the problem, but I'm not convinced this solution would do much to solve the problem?
1. LLMs give this doc special preference and SEO type optimisation will run rampant by brands.
2. LLMs crawl this as just another page, and then you need to ask yourself why isn't this context already on the website?
I do agree with the other commenters about this being better solved with a <link rel="llm"> or just an Accept: text/markdown; profile=llm header.
It's not given that a site only contains a single "thing" that LLMs are interested in. To continue your dev-doc example, many projects use github instead of their own website. Github's /llms.txt wouldn't contain anything at all about your FastHTML project, but rather instructions on how to use GitHub. That is not useful for people who asked Cursor about your library.
Slightly off topic: An alternative approach to making sites more accessible to LLMs would be to revive the original interpretation of REST (markup with affordances for available actions).
The very idea is a bit silly, why would you help an llm understand a website!? Isn't that proof that the llm is less than capable and you should either use or develop a better model? Like the whole premise makes no sense to me
Had the exact same thought some time ago now, even proposed it internally at my company. What makes me doubt this will work eventually is that scraping has been going on forever now and yet no standard has been accepted (as you noted robots.txt serves a different purpose, should have been called indexation.txt)
I "scrape" some sites[0], generally one time, using a single thread, and my crap home internet. On a good day i'll set ~2mbit/sec throttle on my side. I do this for archival purposes. So is this generally cool with everyone, or am i supposed to be reading humans.txt or whatever? I hope the spirit of my question makes sense.
[0] my main catchall textual site rip directory is 17GB; but i have some really large sites i heard in advance were probably shuttering, that size or larger.
I find it confusing that author proposes llms.txt, but the content is actually markdown? I get that they tried to follow the convention, but then why not make it a simple text file like the robots.txt is?
Yes, and .py is "plain" text too. The extension however helps with signaling the intend of the file. Also, there is something to say for the argument "there is no such thing as plain text" [0]
If you had python code and you didn't want it to have syntax highlighting or be run/imported or any of the other normal things that you do with python files, it might make sense to have python code in a .txt. file.
Same idea here IMO. .md would signal the wrong intent, as you don't want to render it to markdown formatting or read as a markdown file normally is. You want it to be read as plain unrendered text.
You have a site, but the crawlers looks at the llms.txt and uses that, except the content is all wrong and bares no resemblance to the actual content of the page.
If you really care about your content being picked up by the scrapers, why not structure it better? Most of the LLMs are pretty much black boxes, so we don't really know what a better structure would look like, but I would make the guess that involves simplifying your HTML and removing irrelevant tokens.
llms.txt is not for crawlers/scrapers, it's for creating context documents at inference time. You place it on your own site -- presumably if you create an llms.txt you're not looking to manipulate anyone, but to do your best to provide your site's key information in an AI-friendly way.
> if you create an llms.txt you're not looking to manipulate anyone
You don't know me :-)
My suggestion is that someone might want taint the data that goes into an LLM.
Let's say you have a website with guides, examples and tips and tricks for writing bash. What would prevent you from pointing the LLMs to separate content which would contain broken examples and code with a number of security issues, because you long term would want to exploit the code generated by the LLMs.
...it gives you a version only the LLM will see, as opposed to having to identify the visitor as a scraper or human and determining if they get the good or bad version.

Instead of putting resources in the root of the web, this is what /.well-known/ was designed for. See RFC 5785:
https://datatracker.ietf.org/doc/html/rfc5785
Instead of munging URLs to get alternate formats, this is what content negotiation or rel=alternate were designed for.
I’m not sure making it easier to consume content is something that is needed. I think it might be more useful to define script type=llm that would expose function calling to LLMs embedded in browsers.
I can think of a dozen reasons why hiding that folder is a horrible idea, and not a single one for why it would be a good thing to do.

Other than static sites, sure.
Eg: https://www.wolframalpha.com/.well-known/apispec.json
Certainly more well used than content negotiation which grandparent also mentioned.
For example:
- Apple uses it for their app to website association files
- OpenID Connect uses it for connection discovery
- security.txt is usually served from .well-known
- JSON Web Tokens uses it for Web Key Sets to verify public keys
- LetsEncrypt uses it for its ACME HTTPS verification protocol.
There's probably more, but these are ones I've personally used.
https://datatracker.ietf.org/doc/html/rfc8615
I think I'll create a new RFC to supersede both to clear up the situation.

Well, for one, there is not nearly enough utilized resources in the world to solve poverty. Taxing everything we can get our hands on would still only provide a fraction of what would be needed to solve poverty. As things sit today, it is mathematically impossible to solve poverty.
There is all kinds of unutilized resources, namely human capital, that could potentially see an end to poverty if fully utilized, but you will never tax your way into utilizing unutilzed resources. A tool to unlock those resources would be useful, and, indeed, there are efforts underway to try and develop those tools, but we don't yet have the technology. It turns out developing such a tool is way harder than casually proposing that we agree to name a file `llms.txt`.
Or that the crib of software (california) with elite engineers (openai comp averages 900k/yr) needs help with a task that indians can do for 3 bucks an hour (web scraping)
1. There is no such assumption. Not even a mention.
2. Such an assumption would have no relevance here anyway.
Do you always struggle to read, or are you playing dumb for comedic effect?
1. Creating a tool based on helping llms train on website implies that: llms have a problem with training on websites (even though html is designed for easy machine parsing of content) and second that llms are still crawling and have not moved on to other harder sources of data.
2. I am challenging those raison d'etre assumptions on the tool. Questioning not only the tool and its usefulness, but its creator's understanding of the state of llm development.
What are you talking about? The tool has basically nothing to do with websites, other than it is assumed the author of the document will provide it to the user via their website and that the user will know to find it there. Technically speaking, the user could, instead, request the document from the author over email, fax, or even a letter delivered by hand. But HTTP is more convenient for a number of reasons.
> llms have a problem with training on websites
If you mean LLMs have a problem with keeping up with current events, yes, that is essentially the problem this is intended to solve. It offers a document you can inject into your prompt (think RAG) that provides current information that an LLM is probably not up-to-date with – that it can use to gain knowledge about information that may not have even existed a minute ago.
You could go to the regular HTML website and copy/paste the content out of page after page after page to much the same effect, but consolidating it all into one place, with an added bonus of being without any extraneous information that might eat up tokens, to copy/paste once makes it easier for the user.
> Questioning not only the tool and its usefulness
Its usefulness is worth questioning. It very well may not be useful, and the author who proposed this even admits it may not be useful – putting it out there merely to test the waters to see if anyone finds it to be. But your questions are a long way away from being relevant to the tool and how it might potentially be useful.
And while I'm here, authors of unix tools, please use $XDG_CONFIG_HOME. I'm tired of things shitting dot-droppings into my home directory.
You're a saint. I have little faith that this will happen but I hope it catches on.
Flatpak has helped me a lot in this matter. Firefox, Thunderbird, Steam, and more are now all contained within a single folder, instead of making at least one file (dozens in the case of Steam).
It's ironic that the authors of flatpak have been very resistant to adopting this particular XDG specification.

A few deep ironies actually.
robots.txt exists, but is mainly for crawling and also not sure anyone follows it or even if they don't follow what's the punishment.
Some AI companies follow robots.txt (OpenAI and Google, for example) but others ignore it. There's also other limitations around using robots.txt to sole this problem: https://searchengineland.com/robots-txt-new-meta-tag-llm-ai-...
And we already have plenty of standards for library documentation. Man pages, info pages, Perldoc, Javadoc, ...
Of course this then leads to a problem. Your API client isn't allowed to invoke hard coded actions or access hard coded fields, it must automatically adjust itself whenever the API changes. In practice means that the types of HATEOAS clients you can write is extremely limited. You can write what basically amounts to an API browser plus a form generator, because anything more complicated needs human level intelligence.
Does this solve a problem llms actually have?
Not trying to be negative, i'm honestly curious.
Here are a few things that I see;
- Please make a proper shareable logo — lightweight (SVG, PNG) with a transparent background. The "logo.png" in the Github repo is just a screenshot from somewhere. Drop the actual source file there so someone can help.
- Can we stick to plain text instead of Markdown? I know Markdown is already plain but is not plain enough.
- Personally, I feel there is too much complexity going on.
To explain the reasoning for this proposal, by way of an example: I recently released FastHTML, a small library for creating hypermedia applications, and by far the most common concern I've received from potential users is that language models aren't able to help use it, since it was created after the knowledge cutoff of current models.
IDEs like Cursor let you add docs to the model context, which is a great solution to this issue -- except what docs should you add? The idea is that if you, as a site creator, want to make it easier for systems like Cursor to use your docs, then you can provide a small text file linking to the AI-friendly documentation you think is most likely to be helpful in the context window.
Of course, these systems already are perfectly capable of doing their own automated scraping, but the results aren't that great. They don't really know what's needed to be in context to get the key foundational information, and some of that information might be on external sites anyway. I've found I get dramatically better results by carefully curating the context for my prompts for each system I use, and it seems like a waste of time for everyone to redo the same work of this curation, rather than the site owner doing it once for every visitor that needs it. I've also found this very useful with Claude Projects.
llms.txt isn't really designed to help with scraping; it's designed to help end-users use the information on web sites with the help of AI, for web-site owners interested in doing that. It's orthogonal to robots.txt, which is used to let bots know what they may and may not access.
(If folks feel like this proposal is helpful, then it might be worth registering with /.well-known/. Since the RFC for that says "Applications that wish to mint new well-known URIs MUST register them", and I don't even know if people are interested in this, it felt a bit soon to be registering it now.)
1. LLMs give this doc special preference and SEO type optimisation will run rampant by brands. 2. LLMs crawl this as just another page, and then you need to ask yourself why isn't this context already on the website?
It's not given that a site only contains a single "thing" that LLMs are interested in. To continue your dev-doc example, many projects use github instead of their own website. Github's /llms.txt wouldn't contain anything at all about your FastHTML project, but rather instructions on how to use GitHub. That is not useful for people who asked Cursor about your library.
Slightly off topic: An alternative approach to making sites more accessible to LLMs would be to revive the original interpretation of REST (markup with affordances for available actions).
[0] my main catchall textual site rip directory is 17GB; but i have some really large sites i heard in advance were probably shuttering, that size or larger.

Same idea here IMO. .md would signal the wrong intent, as you don't want to render it to markdown formatting or read as a markdown file normally is. You want it to be read as plain unrendered text.

Unrelated, but the comment two steps above has the same username pattern as yours (3 letters+00)
iflath wasn't change enough?
You have a site, but the crawlers looks at the llms.txt and uses that, except the content is all wrong and bares no resemblance to the actual content of the page.
If you really care about your content being picked up by the scrapers, why not structure it better? Most of the LLMs are pretty much black boxes, so we don't really know what a better structure would look like, but I would make the guess that involves simplifying your HTML and removing irrelevant tokens.
You don't know me :-)
My suggestion is that someone might want taint the data that goes into an LLM.
Let's say you have a website with guides, examples and tips and tricks for writing bash. What would prevent you from pointing the LLMs to separate content which would contain broken examples and code with a number of security issues, because you long term would want to exploit the code generated by the LLMs.
I don't think the public sentiment around scrapers and LLMs is that friendly.
I personally think scraping is very important and it allows for smaller players to compete (as long as you're careful about the number of requests).
