I have been building Rebuno, an open-source execution runtime for operating AI agents in production. It manages execution state and guardrails across agents built with different frameworks.

Agents run as HTTP services. Rebuno dispatches work through signed webhooks and keeps execution state in Postgres. Agents submit tool and model calls to Rebuno as steps before executing them.

For each new step, Rebuno evaluates per-agent YAML policies, independently of the model's prompt. It can allow the call, deny it, or hold it for human approval. The agent executes permitted calls and reports their outcomes. Policy decisions and step outcomes are both recorded in one append-only event log.

After an interruption, the agent starts its handler from the top. Steps with recorded outcomes return those outcomes instead of executing again. A crash can also leave a tool with no recorded outcome. Tools marked safe_to_retry run again, and tools marked at_most_once fail as indeterminate. How the agent handles an indeterminate step is up to its implementation.

There are Python and TypeScript SDKs, and the repo includes examples using LangChain, CrewAI, Pydantic AI, Vercel AI SDK, and Mastra.

Rebuno is free to self-host and released under the MIT licensed.

I'd be interested in hearing how others are running or operating agents in production.

I often see people reach for the mouse to select text or close a tab, even when they're already typing. Most know how to copy and paste with the keyboard, but use the mouse for almost everything else.

I use the mouse plenty myself, but a few shortcuts have become habits. You don't need to learn that many to find them useful. Things like moving between words or selecting a whole line come up often and are mostly universal across apps and operating systems.

I think most people just get used to doing things with the mouse. Learning shortcuts takes a bit of effort, and looking through a cheatsheet doesn't help much if you don't use what you've learned right away. I wanted to make something where you could practice them as you go.

That’s why I built Shortcut Express, a small desktop app that teaches shortcuts for everyday tasks. You practice them in a simulated text editor, browser and other familiar parts of an app.

Completely free and open source. Available for macOS, Windows and Linux.

Hey all,

James here (creator of Hazumi for HN), after years of working on Hazumi for iOS/Apple Watch, I finally brought all the app's features to Web with tons more that I think you're gonna love

Radar - watch any post for changes, you get a browser push notification - set a custom topic or select from what's there, when it's posted you get a browser push notification

Profiles - you can view any profile and browse their latest activity, posts, comments and stats

Feeds - add custom RSS feeds to your home page - add an automatically refreshing HN search feed for topics your interested in on HN

Posts - each post is enriched with SEO metadata pulled from the linked site - AI summary of the story too

Weekly digest - an in app weekly newsletter (automatically compiled top weekly stories and their summaries)

Bookmarks - not much to say here but collect stories and organize them as you want

I'd love to hear what you think, how I can improve it, what you want added

Thanks! James
