Hello :wave: I created two custom tools for collecting information from webshops. Such information is the name of the web store, the product link, the price and the stock information. After these informations it lists the results in a table. For this, I created a custom Google search tool that is similar to the built-in Google search tool, but I can limit the number of results and I was able to create a separate programmable search that only use by this tool. This was necessary so that the results only contain relevant webshops. The next custom tool is similar to the Discourse web browsing tool, but I optimized it specifically for web stores. So, first of all, it searches for the JSON-based schema.org format “Offer or Product” located in and runs within it and searches for the necessary data (price, stock information). If this does not yield results, it starts searching for the same based on the itemtype. If this does not yield results either, then what the web browser tool does by default comes up, which is to start reviewing the main contents of the page and search for the necessary information. Another important thing that has been built into this is the token limit. Where I can set the maximum token limit while browsing. It is currently 3000. But the reason I am writing this topic is that is there any kind of limit in tool usage? Because I noticed that after 5 tool usages the process is interrupted. This is the other reason why I built the results limitation in the custom search. I set it to 4 because then browser tool can run success. If I set it to 5 the browser tool will fail on the 5th tool usage. :arrow_down_small: For example: in an answer after 1 google search and 5 web browsers in a row I get a warning in /logs.

`block in safe_thread' I don’t know exactly what cause this, maybe it’s a limitation. If yes, is there any chance to add a setting to the persona or to the custom tool to set up the tool consecutive usage limit in an answer. Edit: I found this which is probably the limit. It would be great to have the ability to override with a setting I mentioned above. lib/ai_bot/bot.rb fe44d7815 # frozen_string_literal: true module DiscourseAi module AiBot class Bot attr_reader :model BOT_NOT_FOUND = Class.new(StandardError) MAX_COMPLETIONS = 5 MAX_TOOLS = 5 def self.as(bot_user, persona: DiscourseAi::AiBot::Personas::General.new, model: nil) new(bot_user, persona, model) end def initialize(bot_user, persona, model = nil) @bot_user = bot_user @persona = persona @model = model || self.class.guess_model(bot_user) || @persona.class.default_llm end Thank you :slightly_smiling_face:

[image] Don: the Discourse web browsing tool What is the Discourse Web Browsing Tool, and where can I find/get it?!

I guess it refers to tools that an AI can use. So, these can enable when editing AI-personas.

I haven’t encountered this issue yet, but if it is indeed a hardcoded limitation then it’d indeed be cool to be able to override it! [image] denvergeeks: What is the Discourse Web Browsing Tool, and where can I find/get it?! In the personas provided by the plugin by default there is the “Researcher” one. You can check it out to see how it works :slight_smile:

What LLM are you using? Is your LLM returning over 5 function calls in a single response, as in they are parallel function calls? Can you share that LLM response?

[image] Falco: What LLM are you using? GPT4o, GPT4o Mini, Gemini Flash 2. Honestly I tried it with a lot LLM. :grin: [image] Falco: Is your LLM returning over 5 function calls in a single response, as in they are parallel function calls? Yes, This is happening when I set Forced Tools and add a system message to the Persona to check things. For example: “visit all website founded on google search” This is necessary for a use case that I have. [image] Falco: Can you share that LLM response? I’ll send you an example in PM because that’s could be an inappropriate content for public. In that example the bot is using the Google Search and Web Browser with Gemini Flash 2.

[image] Don: Yes, This is happening when I set Forced Tools and add a system message to the Persona to check things. For example: “visit all website founded on google search” This is necessary for a use case that I have. I think I see the bug here… generally max_tools was there to avoid huge chains with tool calls, but there are probably 2 different types of max: Max times we round trip with the LLM prior to replying Maximum amount of tool calling (which can be much higher) Maximum amount of context tools can inject. (eg: if you blow the context in 3 tool calls and then pile on another 2 that cause the model to forget about 2 tool replies) Going to have a think about this, it is solvable.

recently I bumped the numbers way up, how is it looking now?
