The Ultimate Tool Stack for AI Agents

图片
  This image shows a poster titled “The Ultimate Tool Stack for AI Agents” (created by Rocky Bhatia). It organizes the AI agent ecosystem into layered categories — essentially a reference map of the modern agent development stack. Here’s a clear breakdown of what it’s showing: 1️⃣ Orchestration Platforms Purpose: Coordinate workflows and manage how agents operate. Examples shown: LangChain Hub Make.com n8n Reka CrewAI + LangGraph PromptLayer Cognosys Flowise These tools help define how agents think, plan, and execute steps . 2️⃣ Tool Use & API Integration Purpose: Give agents access to external tools and real-world actions. Examples: OpenAI Functions Anthropic Tools LangChain Tools Zapier AI Actions SerpAPI BrowserPilot ShellGPT This layer lets agents: Call APIs Search the web Control browsers Use structured function calls It’s what turns an LLM from a chatbot into an action-taking system . 3️⃣ Agen...

 Experiment 39: String standing wave 1 Experimental purpose Observe the standing wave phenomenon formed on strings and rings, study the conditions and rules for the generation of standing waves, and understand the normality of string vibration. Patterns and sound patterns of stringed instruments. 2. Experimental device The experimental device is shown in Figure 39-1, including an electric oscillator, a vibration source, a string (circular elastic band), and a steel wire ring. root. The vibration signal is generated by the electric oscillator and output to the vibration source in the vibration source box. The vibration source is modified from a speaker and connected to A vibrating rod, the vibration source drives the vibrating rod to vibrate up and down. The vibration frequency and amplitude of the vibrating rod can be determined by the electric oscillator The frequency adjustment knob and power adjustment knob control and adjust. The vibrating rod can drive the string or steel wire...
