Agent Use Interface (AUI) – let users bring their own AI agent
As I started building AI integrations, I came to realize that for many projects, the the best agentic experience is one that simply enables the user's personal agent to take actions within your app. The existing options like MCP or A2A are quite involved and for simple apps that are already URL parameter driven, those options seem like overkill. This led me to prototype the Agent Use Interface (AUI) spec. The idea is simple: a lightweight, open spec that makes any app "agent-navigable." You drop an XML file at /agents/aui.xml that describes the URL-parameter-driven actions your app…

What it does
The Agent Use Interface (AUI) is a lightweight, XML-based schema that enables LLM agents to discover and construct URL-parameter-driven tasks on behalf of users. - FRE-Studios/Agent-Use-Interface
A lightweight, XML-based schema that enables LLM agents to discover and construct URL-parameter-driven tasks on behalf of users. AUI describes actions that are performed by composing query parameters onto a base URL — things like searches, filters, form pre-fills, share intents, and configuration links. It is intentionally narrow in scope: AUI is a lightweight XML catalog, served at /agents/aui.xml , that both agents and humans can read. Large sites can split full task definitions into linked detail files. < aui xmlns = " https://agentuseinterface.org/schema/0.1 " version = " 0.1 " > < name >Example Shop</ name > < origin >https://shop.example.com</ origin > < description >An online…from github.com

Hey HN! We built a browser-based agent that runs inside an authenticated web app, watches how the app calls its own APIs, and automatically turns those into agent tools. You can think of it as an auto-generated MCP server that self-updates as the host app changes. The result is a skilled AI assistant that actually integrates deeply with any product (not just chat and RAG) with minimal effort. Check out these short demos below that show the agent in software you're probably familiar with: - Jira: https://demo.frigade.com/hn?skill=jira - Spotify:…
Agent-desktop – Native desktop automation CLI for AI agentsMay 2026 · github.com · ▲99I've been building computer-use tools for a while, and I quietly launched this about a month ago (122 Stars on GH). I figured it was worth sharing here. Over the last few months, a lot of computer-use agents have come out: Codex, Claude Code, CUA, and others. Most of them seem to work roughly like this: 1. Take a screenshot 2. Have the model predict pixel coordinates 3. Click x,y 4. Take another screenshot 5. Repeat That works, but it's slow, expensive in tokens, and fragile. If the UI shifts a few pixels, things break. And the model still doesn't know what any element actually is. But the…
