Just released evmstate, a TypeScript library to trace & visualize state changes on EVM chains, with human-readable labels (variable names, mapping keys, decoded values, etc).

You can now open SSH on a sandbox from Silo and connect from this machine or another. Works with a terminal or an agent harness, against a local or remote VM. github.com/0xpolarzero/silo/…
Silo: a native macOS/Linux app for sandboxes on your machine or remote ones. Powered by MicroSandbox. Meant for letting agents run wild in isolated Linux VMs. Open a workspace in your editor or terminal, forward ports, keep secrets on the host, scope GitHub access per sandbox, snapshot the environment. github.com/0xpolarzero/silo

Installers are here: github.com/0xpolarzero/silo/… I built this for myself, but if you end up using it, issues and PRs are welcome ! And if something feels worse than just doing it in a terminal, please tell me.

zhipu absolutley nailing pursuing the element that played in oss models favour from the HF incident masterclass in adpating goals and roadmaps to informatin as they come. anthro and oai neuter you cause they believe humans are more bad than good and they need to control every outcome. kimi and zhipu are there to serve you cause they beleive the future is built toghther in the open and no one person or group can pursue that. individualism and collectivism battling it out on the grand stage

STRONGLY recommended reading You're in for a treat at the end, you won't even have to bookmark it for "putting it into practice later": it's a tool that lets your agent put it into practice for you...
Because I’m trying to teach agents how to orchestrate agents, everything I have learned - prompt engineering - context engineering - harness engineering - workflow engineering - backpressure Is all documented in a pretty compact form in the Smithers docs. The goal is to make an agent so good at this skill you just talk to the agent. But in meantime you can up level yourself by reading this: smithers.sh/guides/context-e…

Tokens are just intelligence, with enough intelligence you can solve anything
These are the entirety of his prompts. Bro literally did the "make no mistakes" meme until the model solved a math problem that had been open for 30 years.

Monitoring has landed in Smithers 0.18.0! 🚀 We also shipped some of the most asked for features - Ability to share and use other users workflows - Node.js, Browser, Cloudflare worker, and Vercel support - And a lot more! 🧵

Only Smithers supports this feature: Time Travel No other orchestration framework is built from ground up to be this observable debuggable and durable while supporting multiple providers 1. Smithers saves "frames" to sqlite everytime updates happen 2. JJ snapshots the state of the file system every frame 3. The frame provides perfect visibility into what smithers is doing and why 4. You as the user can time travel back to any frame at any time reverting botht he file system and the state of smithers to that frame

Best way to make a harness is with smithers You get the holy trinity of orchestration for free: durability, observability and composability It makes your agentic systems durable, inspectable, and composable with clear coordination between agents, humans and programmatic code
Smithers is an orchestrator. It does not compete with harnesses

LLMs still barely understand your intent, have no taste and require constant babysitting. You can't stay outside the loop for long on any complex-enough problem. It's still a dumb slop machine and it's great; you're still forced to learn from its poor choices.

Has been a while since I wrote about agentic engineering, so this time around some learnings of maintaining Pi as a junior maintainer to @badlogicgames :) lucumr.pocoo.org/2026/5/24/p…

The bun rewrite is some of the most impressive harness engineering I've seen. @jarredsumner basically first invented his own minimal version of Smithers and then thoughtfully created what is a high quality zig to rust compiler utilizing llms Since it's one of the best examples of building a long running workflow I have seen I am busy porting it to using Smithers directly as a demo

gstack is one of the most interesting AI repos Hear me out, it points to a new kind of app: a Markdown app. - The language is markdowny agentic harness - The language is markdown - The app is the workflow. And it works! It works so well it's fair to ask "why smithers?". Clearly all workflows can just be human language skills. So what is the point of smithers? Is it not overengineering. To answer this question I migrated gstack to smithers. The results: - 31 gstack skills went from generated Markdown procedures to typed Smithers workflows. - The old workflow surface was ~42k lines of generated `SKILL.md`. - The new workflow surface is ~5.4k lines of typed `.tsx`. - Gstack skills can be composed as react components - Smithers resumability, inspectability, replayability, forking features, and UI all plug right in But most importantly, I didn't migrate the workflow. An agent did. The point of Smithers is agents love structure. And if you give your agent smithers it's ability to orchestrate itself for reusable long living workflows explodes. And since the programming model of smithers is so similar to React, agents are already great at intuitively know how to build complex workflows with smithers from their pretraining on React. So smithers isn't an alternative to Markdown app programming. It's a more powerful way of doing it. It allows your agent to communicate both in human language and real control flow in a structured way agents love Check out smithers docs: smithers.sh And check out gsmithers: github.com/smithersai/gsmith…

My most valuable insights in term of development with AI (and dev in general) come from @FUCORY (or from working with him). There is a good chance you wanna use smithers, and if you do you’re blessed, cause you’ll be able to shape it with your feedback, or customize it yourself.
Smithers is the new IDE. Imagine if you could Use Smithers via a GUI (picture 1) - Scrub through your entire Smithers history - See the scheduled tasks and results at any time - Fork or chat with an llm or view logs But what if this GUI was actually a terminal (picture 2) - Powered by lib ghosty - Built in native code (no electron or tauri) - Powered by tmux under the hood - Supports all agents and subscriptions first class But with IDE like cmd+p functionality (picture 3) - Rich diffs - Command+P search pallete to open tabs or run smithers workflows in background quickly - Notifications for when workflows need you Supports an in app browser (picture 4) Also (not pictured) - First class VCS support for JJHub and Github - An operator agent who can control anything within the gui (have an agent talk to your agent) - Powerful visualizations - Vim mode (open all files in neovim by default) - Useful keyboard shortcuts - Visual/audio notifications when something needs attention - An exciting roadmap

I sent a prompt detailing a product to Figma, Lovable, v0 and Replit to see which one I like best. All on free plan. So might as well share my thoughts. All of these screenshots are after a one-shot prompt.

Replit (Economy, idk model either) Perfect and well-thought-out layout; clean and readable. More bloated than Linear, but in a sensible way. Interestingly, it was the most “modern,” in the sense that it showed agentic stuff more intuitively than existing tools. Less thorough than Lovable in implementing everything I asked for, but after a second short prompt it fixed it. Most faithful in following Linear’s design. Very personal style, but I liked the color choices better; they were lighter than the rest, and the overall palette was very smooth on the eyes. Same for the fonts.

I feel like the one I like best is Replit; I can't decide for sure vs Figma. They are all decent tho. I lied about the one-shot prompt I told Replit agent something like "you forgot this implement it as specified before".
