🧠 Build AI agents with Think-Plan-Act architecture using Llama-4 reasoning

!image.png(fileId:1106) 🧠 A plug-and-play n8n workflow that adds LLM-powered reasoning, planning, and action to your automations — with prompts, schemas, and full agent logic included. Ever wish your n8n flows could think before they act? Now they can. Say hello to the ultimate agent-based upgrade: "Think → Plan → Act" – fully automated. Fully intelligent.⚡ 🧩 What Is This? This product is a ready-to-use AI-powered workflow template for n8n, featuring a smart “Thinking Agent” that: 🧠 Analyzes tasks 📋 Generates a step-by-step plan 🛠️ Executes actions intelligently 🧾 Returns structured JSON outputs for your next steps Inspired by the Hugging Face agent architecture, this template gives your automations a brain before they press the red button. 🔴✅ A clean 2-step process: THINK mode → Generates structured reasoning (goal, subgoals, tools, assumptions) ACT mode → Executes subgoals step-by-step using tools and AI. 🧬 What's Inside? This isn’t just a flow — it’s a framework. You get: 🔹 Modular Agent Loop 🔹 A demonstration workflow 📝 Requirements 🔹 OpenRouter API Key (or any other provider like OpenAI, groq...) 🔹 Built-in Parsers 🧾 Structured JSON parser for reliable outputs 🪄 Natural language and unstructured parsing fallback 🛠️ Plug in your own goals, tools, and OpenRouter keys 📦 Includes a demo (e.g., “get the weather”) to get started fast 💡 Why You'll Love It ✅ Plug & Play – Drop into any existing n8n flow ✅ Tool-Aware Reasoning – Plans include which tool to use and why ✅ Composable – Build workflows like agents: Reason → Plan → Execute ✅ Customizable by anyone – Even your intern can tweak the prompts ⚙️ Agent customization 🔹 Feel free to customize the agent settings by changing the Config node. Here's the default configuration: ts const config = { THINK: { CONTEXT: , // Add the necessary context to the AI. CONSTRAINTS: Rule 1, Rule 2, // here are the rules that your AI should follow TOOLS: { tool: "", description: "", }, , // add here the list of the tools that the AI will call in your backend or workflow. }, }; return { json: { config: config, input: $input.last().json, }, }; After updating the configuration file, you will see the AI reasoning for your input. Feel free to connect with any other node creating smart tasks!
