Meta Agent: Describe a problem, get a working AI agent (Muse Spark)
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

Imagine you need to book a train ticket, or find a meeting slot that works for your team in Bangalore, London and San Francisco. You wouldn't trust a chatbot with that. LLMs hallucinate, they'll confidently hand you a meeting time that doesn't exist, or get the daylight-saving switch wrong, and you won't know until it's too late. So you'd want a proper agent built for the job. But you're not technical. You don't know how to write one, test one, or deploy one. Allow me to introduce Meta Agent. Tell it your problem in plain words. Meta Agent creates a dedicated agent just for that task, one you can chat with to get the job done. No code, no setup, no technical decisions. How it works - You describe the problem. "Find meeting times for my team across three cities." - It asks a couple of simple questions and shows you a plan in plain English, including what the agent will not do. - You say yes. Meta Agent, powered by Muse Spark, writes the agent, writes tests for it, runs them, and fixes its own mistakes. - You approve, and it's live. Your new agent appears in your sidebar, ready to talk to. Already built something similar? Meta Agent points you to the existing agent instead of building a copy. Why it beats asking an LLM Your agent doesn't guess; it computes. In our demo, the meeting agent built by Meta Agent: - told us honestly that no slot works for all three cities, and offered fair alternatives showing exactly who stretches and by how much - found 3 slots a day in the week the US had changed its clocks, and 1 the week before Every agent is checked before it runs, can only reach what it's allowed to. Where it's heading Today, Meta Agent builds agents that think reliably: scheduling, loan planning, attendance, expense splitting. Next, they'll act for you: booking tickets and making payments through official providers, with you always giving the final yes. Your OTP never leaves your hands. Meta Agent: tell it your problem, get your own AI agent. Built with Muse Spark on the Meta Model API.
