CLIs Are All You Need for Agents
Fun agent I've been playing with - the idea is it only has access to a bash tool, and it's directed to create CLIs for use (with additional direction to make the CLIs composable, follow the Unix philosophy, etc). It persists these CLIs and knowledge about them get injected into the system prompt dynamically, so each time it runs it gets access to a larger and larger toolset of composable CLIs. One interesting dynamic that's emerged from this is I've started using these CLIs myself since they're the same interface for the agent or for me, and it's turned into kind of non-chat channel to…

What it does
Contribute to caesarnine/binsmith development by creating an account on GitHub.
An agent that accumulates small CLI tools in a persistent workspace. Most chat-style agents are “stateless” in the sense that they don’t leave behind reusable artifacts. Binsmith is configured to turn repeated work into scripts and keep them under workspace/bin (by default ~/.binsmith/workspace/bin ), so later tasks can compose existing tools instead of re-solving the same problem. export GOOGLE_API_KEY=... # see below for other providers uvx binsmith This starts a local server and opens the TUI. A web UI is also available at http://localhost:8000 while running. By default, Binsmith uses a global data directory at ~/.binsmith/ so your tools carry across projects. To keep storage in the…from github.com

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…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
