A year ago, "agent harness" was tools in a loop. In 2026, AI agent harness companies (Claude, Cursor, Codex, etc) are competing on: • How you can call your agent (local computer, mobile remote, messaging apps, tag in slack) • How it calls itself automatically (heartbeats, Cursor automations) • UI for humans (From Cursor's excellent accept/undo/revert interface, to Claude Cowork, to how easy it is to install MCPs in Claude desktop) • Where it runs (was always local, now we have cloud agents on github) • Support for skills (to catch up, Cursor peers into Claude Code's folders) • Keeping context clean with subagents (I love Cursor's use of Opus to prompt the cheap/fast Composer - they make a great team) • Smart context editing (not just blunt compaction at blunt milestones) I'm sure a bunch are slipping my mind. What else should be on this list?

Claude Code is going mega viral on X. You probably feel overwhelmed with all the content. Don't read it all - instead, just read this one article. I filtered down the 1% of content/tools/resources that are actually worth your time (part two). Guarantee you'll extract alpha.

Giving Obsidian a shot for the 7th time in my career. I've been using straight up markdown + VS Code for notes for over 10 years. I've have brief stints with evernote, Jupyter with Deno and a few others, but nothing has stuck. send me your tips

Nice to see Google Docs rolling out better Markdown support. If you use Obsidian this will make it easier to collaborate with your coworkers who need to use Docs. I ran into this often at my previous company when working on blog posts and internal memos. Next, I'd love to see Google add support for copy/pasting Markdown

here you go... next version of Obsidian Web Clipper has nice Markdown export for Claude and ChatGPT out of the box
Andrej Karpathy@karpathy

@tylerangert @OpenAI @AnthropicAI 💯 I especially need this for Deep Research, which I very often want to export as markdown into an Obsidian note for later reference. I spent 1 hour the other day trying to write this, then 1 hour searching for someone who surely has done it already, but now I'm stuck.

MarkDown 已经成为我的生活中最重要的文件格式了。 Typora 虽然是非常好的 MD 编辑器,但是有个很大的痛点: 每次 Agent 改完文件,都要手动关掉再打开才能看到变化。 这个操作一天要重复几十次,很烦。 今天决定自己解决这个问题,开发了一个新的编辑器 ColaMD: Agent 在后台改你的 .md 文件,你眼前的内容实时刷新。 就像是在看 Agent 现场写作,体验彻底改变。 相比其他编辑器的 区别? - Obsidian 功能强大但太重了,我只是想看一个 .md 文件,不需要打开一整个知识库。 - Typora 是我用过体验最好的编辑器,但它不支持文件被外部修改后实时刷新 - 其他付费软件,Markdown 是一个基础格式,免费的编辑器也应该更加普及。 所以 ColaMD 的定位就是: 一个轻量的、免费的、为 Agent 时代设计的 Markdown 编辑器。 没有文件管理,没有知识库,没有插件系统,没有 AI 功能。 对了,icon 设计了 20 版,最后选了一个极简的版本,希望你能喜欢。 MIT 开源,免费,macOS / Windows / Linux 都能用。 GitHub 地址:github.com/marswaveai/Col… 好记的域名:ColaMD.com

I have tested nearly every markdown editor available on the market, as ~95% of my work now takes place in markdown files. Top picks are: - iA Writer remains a leader because it is the most reliable, offering a clean design and only the most essential features. While I wish for more styling configuration options, the writing experience here is the best. I do not know what kind of voodoo they do, but it works. - Obsidian is the second most reliable option for markdown editing. It simply works. However, for some reason, the writing experience in Obsidian feels significantly worse than in iA Writer. While this may be subjective, it relates to the smallest details of the typing experience. Obsidian improves a lot after customization, which has now made it the #1 app in my personal rankings. I list it second only because I have been working with it this way for a relatively short time. - Paper is another app that I have truly enjoyed. In fact, I enjoyed it the most initially, but in the long run, it has proven unreliable due to quirks such as formatting breaks when pasting links or images. Additionally, the file management feels limited, as there is almost no way to organize or jump between files while writing. Regardless, the vibe of this app is excellent, and I wish the creator the best for their outstanding work. - Following its recent updates, Typora seems like a strong candidate for the #1 spot, though the available dark themes could be much better. It also features a minimal file explorer, which is a nice addition. Typora is a great choice, especially if you are looking for a quality writing experience that is comparable to iA Writer in several aspects. Overall, I believe there is space for a @screenstudio quality app built for the AI era, or perhaps more accurately, the "markdown era"

BURKOV@burkov·
Some said in the comments that ChapterPal is "too simple" for 5 months of work. Let's count features: 1. A WYSIWYG Markdown editor that has all the same features as the best commercial editors like Typora, but supports a wider range of non-standard elements like admonitions, LaTeX tables, multi-type figures (like a figure with both code and image). 2. A markdown parser that supports the same non-standard markdown features as the WYSIWYG editor, but runs superfast, allows dynamic token-by-token content revealing, and doesn't slow down even when the document being revealed is extremely large. 3. A context-aware Q&A system that understands what piece of content to send to the LLM so that the answer is based on the document being read and the piece of content that the user is asking about. 4. A subsystem that converts to Markdown from LaTeX, ePUB, PDF, DOCX, and HTML. 5. A cross-document reference subsystem that allows typesetting books with automatically generated numerical references for figures, tables, equations, chapters, sections, and algorithms. 6. Support for several reading modes (normal, dark, and sepia). 7. Support for several reading themes: Pixyll, Github, and academic. 8. Multi-device support: desktop, mobile portrait, and landscape. 7. Voice-based input. ... And I just started to enumerate the features. In five months, I developed three versions of the software, starting two times from scratch because by working on it I encountered challenges that previous architecture wasn't designed to handle. All of it: frontend, backend, database, authentication, scaling, handling of payments, etc., was made by one person who had zero experience with all of the technologies used in the tech stack.

Workbook is built on Markdown. We're building a brand-new Markdown editor with aspirations of making it an alternative choice to Trix for Action Text. Lots of apps targeted at more technical users would do better with Markdown than WYSIWYG.
Jason Fried@jasonfried

Good time to preview the next ONCE product. We're calling it Workbook. You know, it's really easy to publish short form content on a variety of social platforms. And individual blog posts on a number of other platforms. These are solved problems. But it's surprisingly challenging to publish books on the web in nice, cohesive, tight, easy-to-navigate HTML format. A collection of 20 essays can be a book. Or a company's handbook can be a book. Or an actual book like Shape Up can be a book. But usually you have to make a custom web site, or stretch to use a blog publishing tool to kinda-sorta squish separate posts together into a packaged whole. It's really not ideal. We know — we've published a variety of books online, and we've had to go the custom route each time. Having to go the custom route for something that should be fundamentally simple is a red flag. And an opportunity. It really shouldn't be this hard. So we're doing something about that. That's Workbook. It's a dead simple platform to publish web-based books. They have covers, they can have title pages, they can have picture pages, and they can have text pages. Each book gets its own URL, and navigating and keeping track of your progress is all built right in. I'll be sharing much more about this soon, but here's a screenshot on the editing end. This is how you put a book together. Make the pages (there are three styles of pages available), drag them around to put them in the order you want, and Workbook takes care of the rest. A page can be a literal page of text, or an entire chapter — you can set it up however you'd like. Text editing happens in Markdown. Once you're done, and ready to publish, you'd flip the toggle on the left under the cover, customize your URL (at your domain, of course), and the book is live on the web for the whole world to read. Workbook will be a ONCE product, so you get all the code too. And for the first time, it'll be entirely free. You don't even have to pay once! You pay zero! Workbook is our love letter to truly independent, zero-cost web publishing. We'll be republishing all our public books (Getting Real, Shape Up, The 37signals Employee Handbook, etc) using Workbook as well. That's it for now, more soon.

I just put together a what-you-see-is-what-you-get markdown editor called Bioscratch. No subscriptions, just open it and write. supports images, mermaid diagrams, math, code blocks, and exports to HTML or PDF natively. Please let me know your thoughts! broccolito.github.io/bioscratch-lan…

A new fascinating paper in Science Advances (science.org/doi/10.1126/sc…) on the association of a missense variant in EPAS1 that helped Andean highlanders in South America to adapt to high altitude, similar to how noncoding regulatory variants in EPAS1 helped Tibetan highlanders in East Asia to adapt to high-altitude life (pnas.org/doi/full/10.10…). Unlike the Tibetan EPAS1 variants, which are ancient and possibly born in Denisovans and introgressed into East Asians via admixture 48,000 years ago (nature.com/articles/natur…), the Andean EPAS1 variant is relatively young born only ~10,000 years ago. This is a beautiful example of convergent evolution where independent variants in the same gene drive human adaptation in different populations. Probably, the only known previous example of convergent evolution in humans was for lactase persistence where independent variants in LCT helped humans in Europe and East Africa to produce lactase as adults to digest milk (nature.com/articles/s4157…).
