Understanding LangChain Agents and Tools with Twilio & SMS
summary
Overview of a hands-on LangChain demo that wires an OpenAI model into prompt templates, an LMChain, and an agent that uses tools like a calculator and SERP API; shows code (JS) creating a prompt template, calling model.call, and initializing an executor. Example math query returns $15/week and $60/month. Also shows a Twilio SMS hook (716-271-7716) used to send prompts; web search only works when SERP tool is added and rate limits cause intermittent failures.
