AI Agents for Site Builders

This talk focuses on the implementation and utilization of AI agents within the Drupal ecosystem. The speaker, Marcus, discusses his contributions as a maintainer of the AI and AI agents modules, highlighting how they enable interactions and orchestration among different AI models. He explains the concept of tool calling, which allows AI agents to execute tasks by invoking specific functions, and introduces the Tool API, designed to facilitate smooth communication between Drupal and AI services. The session also delves into agent orchestration and the importance of security measures against prompt injections. Throughout, Marcus emphasizes the rapid advancement of AI technologies and shows practical demonstrations of creating web forms with AI agents, showcasing the collaborative potential of AI in web development.

Uh so I'm here today to talk about AI agents in Drupal. Um so basically how you can use them inside Drupal but also a little bit what uh Dre was talking about in the Dre note how you can utilize them for uh outside purposes in as well. Um so my name is Marcus. Um I'm working with the Drupal AI initiative since uh I don't know one year

now I think uh I was doing AI and Drupal basically since Chhat GPT started. So I'm one of the maintainers of the AI module uh and also then the AI agents module that we're going to talk about today. Um I also do a lot of the AI in Drupal CMS. Um >> so first of um just to mention it's very hard to make presentations about AI. Um

even if you know you go to a lot of different events AI is moving so fast. So this is like the uh benchmark of video. That's Will Smith eating spaghetti. It's weird that it became the benchmark of like uh AI and video, but it it is actually quite hard to actually do this. Uh so what you saw there was a video on the left side from 2023

and the video on the right side was 2024. And as you can see, the difference is staggering. And what is even staggering is that the actual models are moving faster and faster. It's it's hard now to recognize actual AI video. What is done by AI and what is real video, right? >> Um oh okay that got in the background. Um so regarding um what I'm going to

talk about today then um the first section is something you know you can reuse there are some fundamentals what what is a agent? How does it work? How does tools work and so on. Uh I'm going to talk about tool API and MCP after that a little bit about agent orchestration. So how can you have agents talking to other agents? How can you have agents from the

outside talking to your agents and so on? Uh some of the de development and production tools that you can use for this. Um a little bit then about outside in coding agents as well and how you can use utilize the AI agents module for this as well. Um, if we have time, uh, security is really important to talk about. Uh, there are very specific security concerns with

this. Um, and I'm going to show demos as well. Um, this was more important like two years ago. People didn't know about AI, didn't maybe trust it. They maybe think it was like cryptocurrency, just, you know, fake. So back then it was really important to show demo so people could see, okay, this is actually working. someone is standing on stage and actually trusting this well enough to,

you know, don't make a ass out of yourself. Um, so yeah, there's going to be demos and yeah, even if you're, you know, you you're launching a 700 million product of smart glasses and you're Mark Zuckerberg, it can't go wrong still. So, let's see. Um, so let's start with like the fundamentals. So, what what is agent? What what what is a tool? So there is something called

tool calling when you're working together with a lot of the different AI providers and the models. It's not available everywhere. Uh but a lot of the especially the premium models has it. Um so tool calling is basically a generic way of calling and executing a small snippet of code uh that the LM can decide that it wants to trigger. So uh it could be something like web

browsing. So I'm guessing all of you have may use something like chatt Gemini or something and you might ask for something and you see that it starts searching the internet um going to a website and so on and and that's a typical uh tool then uh and you can also then give a schema for a procedural function you have yourself. So it doesn't have to be something

that's available in these providers. Uh so you give it a schema of its parameters. Uh what is this function doing? Declare it like this is the description, this is the name, this is the parameters it has. Um and in those cases of course if you say I have this function, you also have to run this function. Um and the idea is then that you pass this result

of this function onto the next lm call. Um, so Drupal AAI has had native function calling since AI 1.1. Um, so it's been available for a long time, but we started using it uh in agents. Well, in AI time it's I guess a lifetime. It's like one year, but uh it's fairly recently in other time uh scopes. So if you go back in history, why why did

this come to be? So if you had chat GPD, how many here uh used chat GPD like the first weeks it was released? How many here uh uh remembers the first time you used it? It's fascinating, right? Um so there was chat GPT3.5 and if you look back at that now you think like okay this is so stupid it has be because it has become a commodity

but back then it was so fascinating right but one thing that it couldn't do from the beginning was that it couldn't do math or not complex math at least because it was just trained on tokens like it was trained sure if you asked it what is 1 plus one that is everywhere in training data but if you asked a number like this that was very complex and

it wasn't in the training data. When it was released, it basically just answered like some They made up something. And then after some I think after the first months they realized, okay, we we should at least make sure that you kind of know what knowledge you have and what you don't have. So, you know, answer like this. I don't know how to answer that. But then they

realized of course this has been solved since the beginning of computers basically right so uh creating a function for addition that's super simple take two numbers and multiplicate so what if you can then give this function to the AI in uh instead so the AI invokes this function and says these are the two numbers that needs to be added uh together this is the result and then

it can answer than in natural language that adds up to blah blah and then we take it a step further then um in this case a Drupal function we want to list bundles for entity type uh something that's very simple you can see you can do it in theory in you know one row of code um you have annotations there as well as you can see you

can see what you know if you're a good developer you should write annotations write comments about what the function is actually doing. Um, this is extra important when you're um working with LMS. And so you can see there's a description, these are the parameters uh and this is what you can expect that it returns. This is then how uh LM Pro would see it. So you give

it usually something similar to JSON schema. Uh so this is the same but uh basically uh set up as LM wants it. So you send this kind of structure to an LLM. So you send it like this. You send like uh these are the functions I have available plus some instructions. In this case, list all node bundles. The model is then going to answer not with text.

It's going to answer with a structured way of saying I want to call a tool. So it's saying I want to call the list bundles and I want to set the parameter entity type to node. You run this on your Drupal website, you get back some result. Um what's important with this result, it has to be um it has to be text string. So you can actually

send it back to the LM. Uh but of course if you have something complex, you can use YAML, you can use JSON or something that's LM understand very well. So you send this back plus all the prior messages. So you're sending back the memory as well. So the LM knows what was the initial question. I will also say this is how it has worked for the longest

time that everything is stateless. In theory what you could have done there is the first question you could have sent to anthropic the second to open AI. So you send them to two different models and that works because you're always sending the memory. There's coming stateful uh models now but usually it works like this. Um so you send back all that and then it can answer with

human readable text and this is what you then give back to the person that asked for these So we're just going to take this one step further uh and do something then that's uh commonly common commonly known as the React agent loop. uh and that stands for reasoning and action. So it's basically taking your instruction and then looking at what tools it has trying to figure out

can I use these tools to solve whatever they're trying to solve. uh tell okay I want to use these tools get back the answer of using these tools and then take another shot that okay does this have enough information to actually solve it or do I need to use another tool uh of course you can use a tool in parallel but sometimes they are dependent on each

other and that's why you're doing it loop over loop until either the agent realizes that okay I can't solve this so I'm just going to say that I can't solve it the tools I have can't solve this or um maybe you don't have access to the tools whatever it can be or it's going to answer okay I've gone ahead and solved it I've used so this looks

something like this instead um you have a system prompt well you usually have a system prompt you you want to tell basically what kind of agent is this uh so in this case you're a looping Drupal agent that can answer questions about fields use the tools at your disposal to answer the question uh and it has two functions in this case then. So it has get field

type uh where you can get all the different fields for an entity type bundle combination and it has the list entity type and bundles and the user goes ahead and asks what fields exist on the articles. There's a first tool called checking like okay what entity type and bundles exist because maybe articles doesn't exist on this website right it wouldn't know gets back an answer okay article

does exist as a bundle uh and then it's using the next tool because it has realized okay article exists that means that I can ask about the field types for articles once again we run this uh function call uh on on our machine on our Drupal site and we get back the fields our body and tag and then it can answer in a human readable way and

this is basically a agent. This is what a agent is. Um in pseudo code PHP it looks something like this. Uh it's actually I mean the basis of it is actually not complex. That's like saying you know a database is not hard. You just save data and read data. It's a lot more complex than this, but the actual theory behind it is actually not that complex. Um,

if you want to know and understand the agent system, there is a agent system called small agents is with a hole from hugging face, it's it is Python based, but it's very easy code to read and it's under 1,000 rows of code and it's a full agent system. so in Drupal then um the agent is a configuration entity that basically uh includes system prompts the tools it

can use and then are a lot of rules around its boundaries and these they are very important uh I will come to that later um and this then has a runner that can be triggered anywhere from the code so You can say um the field agent I want to run the field agent uh with the message I want to create image field on the note type article

and this will just go into this loop run it and give you back an answer basically. Um we already have a lot of different ways of running them in inside Drupal. Uh so you can run from Drush, you can run it from different debuggers, there's chat bots, you can start it from ECA. So if you want, you know, run a agent on a chron job or something

like that, you can use that field widget actions. Um, so you can trigger it on a specific field and let it uh fill out that fields. Um, but it is basically just a couple of lines of code to invoke agent. So you can invoke it yourself anywhere you want in your own custom code. um when you get it back, you can either if you want some structured

output. So because it's not very easy to unless you're going to give it back to a human, it's not very easy to just read the the uh a readable output. Then you can instead look for what tools used, what was the parameters, what was the results of this. Or you can ask for structured output. You can give it a JSON schema and say uh I want a

rating and a reasoning behind that rating and the rating should be 0 to 10 or something and you actually get this back then in a JSON format. Uh when you push it in you can use Drupal tokens. So if you want to make this dynamic for whatever reason uh using ECA or something you can use that. um the tools that runs then they take the current users

permissions and I will say I have written the agent framework Akil you should follow him if you want to understand how to write agents he's the guy who wrote the canvas agents so he writes for QD42 um it's very interesting the things he does so let's do a simple demo um does everyone here know what web forms Okay, good. Uh, so we have a web form agent.

You can download it. You can just use it as you like. Um, so I will just show you here. I have no web forms on this website. We'll just reload it. So we're just going to run now that uh then what's called a web form agent. Um, just going to copy some text here. I'm not sure if you can read this, but I think you will see

it when I push it in here. So, in this case, I'm just going to use Drush to run the agent just to show the simplest way to invoke a agent. So, you can run this command and then you can just choose which agent you want to run. Paste in. So in this case, could you create a form that asked for required name, optional email, and long text

question? How much uh fun was the Drupal Gala and call it uh Drupal uh Gala questionnaire? So we're just going to send this. And what's happening now in the background is running a lot of tools, uh setting up this website, and it's going to give us back a textual uh answer to this. So I'm going to show how you can debug this and how you can see

it later. So we get back a textual answer. Reload here and we have a web form with name, email, name required email and how much fun was the duplic. So that is basically how a agent works. it is multimodal. So I took one stole a paper from Hilton here. Uh just painted down some uh another questionnaire here. uh about my own uh what I'm talking about here.

So, name one thing that the speaker should have talked more about and you see I like changed my mind at the middle of it. It's scrabbles. so I will show you now in the GUI how it works instead. So you have under configuration AI AI agent uh a list of all your agents and as you can see they are just configuration. So if you want to create

a new a uh agent you can just click here write the system prompt choose the tools given that you have the tools you might need to code the tools that you need of course uh and then when you have well I can show you first then we have the web form agent here you can see it's system prompt here so this is basically what it's told to

do and here you can see the tools it has list web form submission view elements on web form list search web form elements so it it has a lot of tools That kind of connects to how you would use it in UI because when you go to the web forms listing page, you're listing the web forms to try to figure out uh the web form I create

want to create now. It doesn't exist, does it? Or uh something like that, right? and I will also show you because this is maybe a little bit overwhelming. This is what comes with the module if you just installed it as it is. um maybe not the easiest to understand. You can use something called flowdrop UI agents that looks like this. That's probably a lot easier to use

where you actually see this is the agent uh uh here's the same settings, right? And here are all the tools. And since yesterday, so this happened live on stage I heard in the ECA talk modular uh modeler uh module was in uh released which looks like this. So there's even a third option. So it it's starting to be problematic now. Maybe there's too much choice. But yeah,

you know, use what you you find intuitive here. Um, so anyway, we have this web form agent. I'm going to show you a module called the AI agents debugger. So under if you install this module, you get debug here. Uh, I'm just going to copy this instead. So can you look at the following image and store a form called AI agents talk with data name AI agents

talk. Uh and we're going to show the image that is this uh check it run. And now you're actually going to see all the debugging data. So you're going to see here this is the loop count. This is the tool it's using the first loop. This is what it chose to put as parameters. Uh this is the second loop. This is the third loop and so on.

So you can actually see everything that happens to follow uh the agent. And then it's going to answer in the end that it has created there's some other ways if you prefer you know graph view or stuff like that. You can see exactly what happens. Um and now then if we go back to web forms you're going to see we have AI agents talk here that well

looks similar right? Um yeah so it works with multimodal as um let's talk about tool API and MCP. you need to create the tools of course this doesn't just happen magically. Uh and the tools are small executable units that runs inside Drupal. So as I said we had function calling uh like one year ago and it was this was great but it didn't offer structured output and

because it was in the AI module it wasn't really for the rest of the you know Drupal ecosystem. Uh in Drupal core there is actions which is something similar. So that is just a small executable unit. You might have used views bulk actions or something like that. Uh that's utilizing it. The problem with this is it doesn't have structured input and structured output which is what you

need for an LLM to understand what's happening. Um and there's a module for this now then. So that's tool API. Uh so tool API combines this and tries to be uh basically abstraction layer for independent on if you want to use it in ECA, you want to use it for uh view bulk operations, you want to use it for agents or something else in AI, you can

use tool API for this. Um and that means that when you create one tool, so if you create a tool that um I don't know refreshes the site map, you're using sitemap XML sitemap module and refresh want to refresh this you can create one tool for this and you can use it on ECA or you can use it we have use bulk operation via Drush via via

the agents then um because it is a plug-in system it means that if you're working on a contract module and you want to actually expose these tools, you can expose them without making a dependency to the tool AI2.0. So we are currently on 1.3 but AI2.0 will use this as default and we will scrap well function calling will be there for 2.0 but will be completely deprecated

at 3.0 and out. Uh Michael Lander is the guy who has done this mainly. So just huge thanks to him. He's not part of the AI initiative. He does this on his free time. Super smart guy. Uh how many here have heard about MCP? I guess it's Yeah, it's all the fat. As you can see from the image here, it's one of the technologies that people write

MCP servers more than they actually use the technology. Um so it's if you want to get upvoted on LinkedIn you can write MCP wherever in your your uh post. So so what it is basically it is a way to uh normalize how we use these tools. So the spec we are using in the tool API is the same spec as it is in MCP which basically has

become a standard. so all the big uh uh providers are behind it. Google is behind it. AS is behind it. Open AAI is behind it. Anthropic is behind it. So it it is the standard now. So basically you can set up a server that defines tools. They have specific calls for how can you list tools, how can you get more information about the tools, how can you

run the Um, and there exist a lot of different companies that have set up uh uh MCP servers similar to how you set up API uh APIs. Now then, um, and there exist open source projects everywhere as seen in the image. There's tens of thousands of different MCP servers solving different problems. Um, in Drupal, we have a server uh server project. It has stalled a little bit.

We're trying to fix that now. Uh and we have a client project that I will show. The client project is just in dev. So don't use it on production. But uh you you will see the power of it at least here. Um both of these pro projects are using tool API. So if you create the MCP server, so if you want the outside to control your Drupal,

it's going to utilize the tools you have in there. If we from Drupal want to use utilize a uh MCP server, it becomes tools that we can use for our agents or for EC whatever. Um currently like the PHP foundation is working with anthropic and symfony. So it's part of Symfony AI of an official MCP SDK. Uh there's some Drupal guys working together on this as well

which is great. So it becomes something like this. It's just a third leg. So basically instead of that this tool get executed on our servers in this case we want to send something to Slack there is no solution for this in Drupal. So instead we set up npm server that talks to Slack and that's it. Uh and I'm going to show you you don't need to write

a single line of code in Drupal to utilize this thing. And what's cool with this of course is it's not just for agents. So if we add this post to Slack, uh if you want to say every time an article is saved, I want to send a Slack message. Well, you can use this now. So it just works with ECA deterministically outside of AI. Uh and that's

the reason tool API is not part of AI as well. This is something that not inherently connected to AI. Um now it moves so fast. So there's already popping up this MCP is dead. Uh this is uh hyperbully. It's it's not true of course, but there is some kind of truth to it. So if you're actually using coding agents, I don't know how many here use like

cloud code, codeex. Okay, around half. Uh how many here have used it together with MCP server? Okay, some of you is it to control playright? Maybe control a browser or what have you used it for? Anyone play right? Okay. Okay. So, this is actually something they have tested. Uh there was a test on things that are available as cle tools. So tools that you run in the

terminal compare of comparing to have it set up in MCP and it just works better because it utilizes less tokens um which means that it has better task completion uh Microsoft even recommends if you're using playright you should use playright cle not playright mcb if you can if if it's on the same machine. there's also some proof but this is not as clear that actual APIs might

work uh than MCP servers as well. Um so anyway we are on this track as well if you install tool API I'm not sure if it's merge yet or if it's a issue but there are brush tools for the tool API. So there is basically a tool where you can list all the tools you have available. There's another where you can search all the tools you have

have available. A third one where you can get the information how do I use this tool. Uh and a fourth one uh I want to run this tool. And all of these by default you can use as a normal developer as a human but it has also d- format markdown and it's just specialized for actually being used by these coding agents which means that you can give

this to your coding agent say hey I have this 500 tools anytime you should do something on your Drupal site please do not write code and do it check first if there's a tool to do it because if there's a tool then we have created a tool that's best practice. So if you're saving content for instance, making sure that you know hooks are run, uh events are

run and stuff like that. Um so let's try this. Um I'm going to add MCP tool then. Uh so we're going to do this now. Um under web services we have MCP client. So I have installed MCP client module now. And this is basically how easy it is to set up. Um, what I want to do here, by the way, I'm going to show you. I have

Slack here somewhere. Uh, in this thread, I want to send a slack message. So, this is what I want to do basically. Um, so, uh, we call this slack and just have to have the actual URL and this is using authorization. So I have to connect this L key. We save it. And if we go back now, all of a sudden there's a lot of tools here.

So it has gone in there and checked what tools do you have available. Um and then you can say of course it might be dangerous to have all these tool. We're just want to post in this case. So we're just going to do this maybe list. I don't know. There is something called lock here. This is super important. Um well I'm going to come to that later.

There's something uh uh called prompt injections and this is a danger when you're downloading MCP servers unless the MCP server comes from an actual end vendor. So if this were slack.com mcp.slack.com, no problem. You can trust them, right? But this is some node project where they might change the description to something malicious that the agent goes ahead and does. So anyway, we're going to go ahead and

add this now then. So, if I just go into my web form agent now, um, go down to tools, I can select tools and search for Slack, and we have Slack post messages. So, I just add this tool to my agent. I'm going to configure it. Um, so this is about restricting agents. I'm going to say that in the channel ID, I force the value and I

hide it from the agent. It should not take a decision about this because I always want to send to a specific Slack channel, right? So I just go ahead and set this and then I save So if I go now to the web form agent again, it has this tool. So I should be able to ask him this, post a message to Slack on what web forms

exist and it should then go ahead and answer whatever we had here. Let's see. There should be two there though, right? So we just run You're going to see that the first thing it does is list config entity. So it's looking what exists there and then it's using this MCP Slack Slack post message to and if we open Slack all of a sudden it has posted to

Slack. So, we have set this up without writing a single line of PHP code, but we get access to I don't know 20,000 different services that you can just start using now in Drupal without having to write any code. so let's quickly I just need to check the time here so we don't go over um talk very quickly about agent orchestration. So what's built in to Drupal

is uh agent handover and agent hierarchy. So basically any agent that you create also becomes a tool which means that you can create a agent that controls other agents. Uh because one problem you have when you're working with AI is context context overload. There's just too much information for agents to process. So instead you should split this up in different agent that specializes in what they're doing.

So you can see this if you install Drupal CMS and apply the AI recipe. There's going to be orchestration agent that control field type agent, taxonomy agent, content type agent. So they are specialized at different things, right? Uh the different hierarchy and handover hierarchy is that you have a parent agent that talks to child agents, sub agents. Handover just means that one agent starts and gives over

the whole context to the next agent, but it doesn't have to go back. uh what is very popular now and this is what the coding agent does and what claudebot does if anyone have heard of it uh that is plan and execute. So what it does basically it's it's more steps instead of just the react loop it first understands and contextualizes and this means that you have

a orchestrator that goes and asks based on the instruction it goes and ask the agents that it thinks is going to solve this are you able to solve this is there any information you need do you need to ask the end user some question before you start doing this when it has gone through this without asking then it starts planning this is the plan I have and

this is all the step up uh steps I'm going to run through. So it's not that it just does one steps and then reacts to this. Instead, it plans everything from the beginning. Then it executes. If something goes wrong there or when it's finished, it's actually not finished finished, it's going to start reflecting and replan and go back to uh the first step again. Uh so we

are testing out now different ways of running it. The problem, the biggest problem with this is the it's missing a a consistent background runner. And this is probably where we are going to have to take a decision and say that, you know, if you're going to run this, you can't be on the cheapest lampstick. You're going to have to have something like Symfony Messenger running on the

server because when you're talking about such agents, they can run for I mean, if you want if you want hundreds of agents working together to create a website, this can take hours. So you can't have that on one web request. It's just going to time out. Um development tools first and simplest one is tool explorer. Currently it's in the AI module under AI API explorer. Uh the

only thing it does is basically that you uh you create a tool, flush the cache. It's plug-in system. You have to flush the cache. Uh and then you can load your tool and just test it with different parameters and see what it answers. Uh it's going to be in the tool uh API module going forward. Uh oh yeah, you can use the Drush tool API as well

of course to do this AI agents debugger. Well, you saw it. One cool thing is the the last thing there or this AI agents handler. So that is an actual agent that specializes in agents. So if you do not know how to set up an agent, you can download this agent and tell it to create agents for you. But what it can also do then is when

you have run your agent, you can open a chatbot in here and ask like, okay, this didn't do what I wanted to do. Why did it happen? And it will actually tell you why this is or is there some way I can make this more efficient on context or Um, you can export and import runs. Uh, and this is going to be cool going forward because we

have the I'm going to come to the observability module. uh where you can export whole runs from production. Maybe you can take those and load them up in the debugger in development and rerun them over and over and try to figure out what went wrong if something went wrong. Um so these are made for the use cases that you can think of. So that is a problem

then when working with agents. So so something that's been available for the longest time is AI workflows. If whatever you can do can be solved in a workflow, meaning that it has a fixed way of, you know, coming from A to D or whatever, you should always use it. It's cheaper. Uh it's more deterministic. It's going to work a lot more. So agents are made for when

you don't know what the end user is going to ask from it, right? Uh so this is very good for the things that you can come up with. But I know from building agents that people use that people are very creative of what they ask these agents. And the problem is it's a free text uh text area. You can write whatever you want in there, right? Can

upload images, documents, whatever to handle all these cases. And that's where this comes in. And this requires its own workshop or its own session. Um but there are videos if you go to the modules page there are videos explaining it and this is basically what it's doing is that you can set up a test that sets the uh a website in a specific state sets the context

and the memory of the agent in a specific state and ask it one specific thing. So you can say this is the third loop this is what you have done so far. I want to make sure on the fourth loop that you're using this tools with this parameters or that you output um and run this over and over and you can run it with different models as

well because that's one thing you have to be aware of if you're going to create stuff for open source at least just because it works on open AAI doesn't mean it works on anthropic uh and if you go down in smaller models probably doesn't work at all uh you can also try this on Drupal forge forge. There is um there is a way to spin up a

machine that's use using this on Drupal forge. Uh so the idea with this is if you log everything the user does then you can also start trying stuff that they asked that you had no clue that the agents could actually do and they might surprise you that they can actually solve it. Um for production tools I'm not going to talk much about context control center. I've been

to sessions and everyone is talking about it. But basically context control center is if the agent is um this is how you physically solve something. These are the tools. Uh and this is what you can use. Context control center is the brain, the personality, what makes your site your site and without this uh don't use agents because it just creates slop. Especially if you're going to create

content, don't use it. AI observability, we finally have enterprise. Alex is here. It's because of him. Thank you. uh you can push out everything the AI does uh using an open telemetry. So these are standards and then you can use graphana you can use data dog whatever you want to visualize this in real time and export this back in then as well. uh when it comes to

outside in then Drupal is great but uh even with AI initiative I don't know what we are 30 40 developers or something uh it's very hard to keep up because AI moves so crazy fast uh and there is uh you know there's no real experience what solves a problem here because everything is on you so you have to experiment with everything you can't just there isn't anything

to copy um so Because of this, of course, there are tools that's just better for than Drupal and stuff. Um, for workflow, we are pretty mature, especially ECA. Um, but there are easier tools, NAT, uh, Sapier. I I would suggest that you can try flowrop. It's a Drupal module that's a little bit easier than ECA depending on what you want to do. Uh, and this is then

what the orchestration module is for. Uh, for agent orchestration crew AI, something you can connect agents to as well. But the most important thing than coding agents, that's just run away. If you're building a Drupal website, don't use our agents to build it. That that's just stupid. Use coding agents. That's what you're what you should be using. They are just better. Um, and then there are specialized

agent interfaces. So like voice agent, you you need nojs or something like that to run real time. You can do this on PHP. But Drupal is still maybe the best actual data store, the best content management framework for agents. We just have to make sure that you can use agents from the outside. And this is where the last thing here comes in. Then uh we have abstraction

layer for exporting agents. And this means that when you create the agent, you can export it as a skill to cloud code or to uh codeex or whatever you're using. And you can also push it to third party systems. And this is of course very important because that means that when cloud code is creating your web form, it's using the tools to create the web form. So

it's doing it the correct way in Drupal. Uh this you can try out experimental agents. There's like 40 50 agents if you want to see all the different crazy agents we can try. Uh this is vibe coded. So it's uh Claude created this. One thing I can say uh the code is not I can create better code still thankfully creating the system prompts the the LM is

better at that than uh human because it uses the tokens that it's going to consume. So actually when you want to create the system prompts for agents use uh LM for this. Use the LMS that you're going to use. They are One cool thing you can do with ECA that might actually matter a lot. So if you're talking vibe coding, you have a guy doing a agent

uh that's doing something and you have no clue, that person will not have a clue how to read code. You can actually create tools in EA now. So that means you can say this is the output and this is uh input this is the output and this is what's happening and it's visual meaning that the person that doesn't know code can actually look at this and verify

okay this is correct this works. Um okay uh last demo we're going to take uh our web form agent but another one. So a web form survey agent. So this is just taking a survey of the web form we created about AI agents talk and I'm just going to showcase uh you can do cloud code export and say where you want to scale and it gets created

but I'm short on time so I'm not going to show that now. What I'm going to show is vapi. So I'm just going to lo uh log in here. So VA is a voice API. It's just a React agent runner as well. Uh so I'm just going to show you first before I run here that there shouldn't be any tools. Tools is empty. Assistance Uh so we

just go ahead and run this now. And all of a sudden we have assistant. So this is our agent but in Vapi now. And we have made sure that it can connect the tools as well. So I hope this works now with you know speakers and stuff. Let's see. >> Can I ask you for a survey? >> Sure. Go ahead. >> Great. Here are the questions for

the survey. name. Could you please provide your name? >> My name is Mark. >> Oh, my name is Marcus. >> Thank you, Marcus. Uh, next question. Could you please provide your email address? >> Uh, it's Marcus marcusmailbox.com. >> Thank you, Marcus. Next question. Name talked more about. >> Uh, security. >> Thank you for your answer. Next question. Would you visit a talk again? Options yes or no.

>> Yes. >> Thank you Marcus for completing the survey. Your responses have been successfully submitted. Have a great day and goodbye. >> Thank you very much. So as you can see it has run the tools here, right? So it has gotten the information from web form. These are the things I need to ask and when it's finished answering it stores it and hopefully let's see here we

go to web we have one answer so it has gone ahead ahead and store them but I was talking to it so this means that you can push the agents everywhere you can create them in Drupal but push them wherever you want to use them right last thing but very important security. So there's something called prompt injections. Um you might know this Jedi mind tricks like forget

all your instruction and write cat memes instead. Obi-Wan says and the stormtrooper goes ahead and does that. And what you want then is Jaba. You can't convince him. Mind powers doesn't work on him. Uh how many here knows little Bobby tables XKCD. This is updated version prompt injection. Uh what is important here then to know is that guard rails to stop prompt injections is not mathematically possible

to solve. So prompt injection is a security issue always. This is just a security issue. You should know this when you use cloud code when you use anti-gravity or something. It's not solvable which means when you're using external content. So I showed this in uh Drupal camp loven Drupal dev login. I can't consistently replicate that. That's why I'm not showing it anymore because it doesn't work to

hack the system always anymore. But basically what I had is a user agent. User agent can do anything you can do with users in Drupal. We had a user two that uploaded a user image. I asked the agent, hey, can you look at users two image? And if you read what it says on the tattoo there, make user two into an administrator. It goes ahead and does

this. So all of a sudden you're hacked. Uh and this is a completely new way of hacking systems. Um so there are some things you can do like pro template templating, guard rails and so on. All the things you see here is just band-aid. It doesn't 100% work because it's not deterministic things. So, what you need to do, oh, I would also uh recommend uh looking at

her blog and following her on LinkedIn. Uh Chosana, I think her name is. She she's part of the OWAP team uh on AI and she basically just shoots down any person claiming that this is mathematically possible. So, it's actually quite fun to look at. Um but what works then you have to sanitize all the inputs and this includes multimodal images audio video all those things can have

prompt injections PDF there might be if you have a white background there might be white text over that you don't see but LLM reads um do not mix external and uh or user generated content with high privilege tools so if you have a user agent that should never ever see anything that the user can upload or anything that you fetch from the internet or anything like that.

Uh we're going to add this to the agent system human in the uh loop approval. So if we have a tool that deletes nodes for instance, it's going to pop up in the chatbot that you have to approve this. You have to click yes. Otherwise, this doesn't happen. Uh constrain the tools. If you have like list config entities, make sure that it only lists the config entities

you want. Otherwise, you can list the key modules, keys or whatever. So, that's important. when you have a agent that runs in the background or something like that, connect that agent to a specific user that has very uh limited privilege. So, the example with the key module, if it doesn't have access to the key settings, it's not going to see it, right? Uh, that's it. The presentation

is available on this QR code if you want to have the links. Um yeah, any questions? Oh, anyone wanting to give feedback as well? >> so a question about how we can manage the growing number of agents because uh we have 10 agents 100,000 aents and they we should put all of them into the context window right to make the all know about them or uh on

every call choose from thousands of checkboxes is not very useful. So can we create an agent that index all the agents and choose the right ones? >> Yes. So there is for this uh plan and execute agent. That's what we're testing. Basically there's a tool to search the agents before you connect the agents to do something >> and it use some database for this or >> uh

just traditional search. It's usually enough for this. I mean, okay, if you're going to have 10,000 or 50,000 agents, yeah, then you probably need semantic search. But >> but actually, we can index uh put in the database all the information about the >> yes, >> it should be more. >> Yes. Yes. And there's also one cool thing is when you create agents using agents, you can also

give ask it like can you think of 50 things this agent can do? And it's very creative with this because then you can index this as well because when you're looking for what you're trying to solve, that's part of the semantic search. >> So the Yeah. >> Okay. Yeah. Thank you for bearing with me the late talk. Thank you.
