[CLI Tool] Show HN: VAEN – Package and import portable AI coding-agent Harnesses Hi HN, I built VAEN (an open source CLI) because I kept running into a boring problem with AI coding-agent workflows: the setup becomes useful, but then it is hard to move.<p>A good, useful agentic harness consists of more than just instructions: skills, mcp servers and more. There should be a better way to share those than just .MD files, and that is why I created VAEN.<p>What works: create a yaml, run the CLI commands as per the repo, and get a .agent file that you can share and extract. Think of how awesome it could be if anyone could use a very useful agentic harness, and share it with one CLI command.

[Other] Show HN: Open-Source AI Racing Harness Hi I&#x27;m Dan from Elodin, making an open source real-time capable flight software simulation.<p>For AI Grand Prix contestants, the wait for the Round 1 virtual qualifier simulation has been grueling.<p>If you’re competing, check out our simulation harness to tide you over, built to match the published competition constraints and message format. It runs against real Betaflight, which we learned requires at least 1000 sensor samples per second to run real-time correctly.<p>The competition warranted introducing a new feature to generate the camera sensor directly in the simulation loop. Typically people connect to Unreal or similar game engine to create a camera sensor, which works well but is very heavy. For the simple needs of this challenge, creating sample directly in the loop is very handy and easy to use. Happy to hear your feedback on this! While it&#x27;s not fancy looking currently, it uses the Rust Bevy game engine, which should allow us to improve the visual fidelity quickly.<p>We all should easily be able to shift our implementation to the published competition sim once it lands. Hope you enjoy and good luck!

[Other] Show HN: Filemat – an open-source web-based file manager Hello HN,<p>I would like to share Filemat, a web-based file manager that I built because I wanted something with a simple setup and file permissions that work across the filesystem (as opposed to permissions only for a folder managed by the app).<p>It&#x27;s self-hosted and open-source (currently in beta).<p>I&#x27;d be happy to hear your feedback<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;bingud&#x2F;filemat" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bingud&#x2F;filemat</a>

[DevOps] Show HN: Posthorn, self-hosted mail without the mail server Introducing Posthorn, a self hosted email gateway. One docker container (or Go binary) between every self hosted app on your VPS and your transactional email provider. Set up Posthorn once, point your apps to it, done.<p>I was trying to deploy Ghost on a DigitalOcean droplet and found that DO and many different VPS services have started to block the default SMTP ports to try to combat the various types of abuse they get. To actually configure my app, I had to hack together a Postfix relay.<p>In another project, I had a static site which had a contact form, but my free Formspree account was occasionally hitting usage limits and I desperately wanted some of the anti-spam features they had gated behind their paid accounts so I put together a caddy module to catch HTTP POSTs and bounce them to my provider.<p>I kept bumping into these same email issues. Many of the services I wanted to host (Gitea, Mastodon, Umami, Comentario) ran into the same limitations. This felt like a really common issue that had no good solution.<p>Posthorn is what I built to solve this. It&#x27;s a small Go binary (or 10 MB docker image) that sits between your self hosted apps and your transactional email provider of choice (shipping with support for Postmark, Resend, Mailgun, Amazon SES or an outbound SMTP relay). It also accepts POSTs from HTML forms to support static site needs while adding security layers such as honeypot fields, origin checks and IP rate limiting. There&#x27;s also a JSON HTTP API that supports Bearer auth for backend scripts or cron jobs that just want a &#x2F;send endpoint.<p>I now use this personally in multiple scenarios and I&#x27;ve spent a lot of time beating this up and testing against what I can validate. I&#x27;d love to hear how this might be useful for you, what breaks and any feedback you might have. It&#x27;s open source under Apache 2.0 and I&#x27;d love contributions. I&#x27;m planning to support and grow this for the long haul.<p>Code: <a href="https:&#x2F;&#x2F;github.com&#x2F;craigmccaskill&#x2F;posthorn" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;craigmccaskill&#x2F;posthorn</a><p>Docs: <a href="https:&#x2F;&#x2F;posthorn.dev&#x2F;" rel="nofollow">https:&#x2F;&#x2F;posthorn.dev&#x2F;</a><p>Longer write up: <a href="https:&#x2F;&#x2F;craigmccaskill.com&#x2F;introducing-posthorn&#x2F;" rel="nofollow">https:&#x2F;&#x2F;craigmccaskill.com&#x2F;introducing-posthorn&#x2F;</a><p>Previous HN discussion on the exact issue I&#x27;m trying to solve: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=43620318">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=43620318</a>

[Other] Show HN: I built a tool to auto-accept AI slop and bigtech devs loves it So, you know how bigtech gives nearly unlimited credits for coding tools and in the same time put a huge admin whitelist of what commands are allowed?<p>So, instead of becoming a 100x engineers, you (including me) simply become a multi-window-enter-clicker<p>I build a tool to solve this. It works locally, using OCR finds the &quot;run&quot; (or any other label you put e.g. accept, allow, fetch etc. ) and just clicks this button.<p>Originally this was a tool for me and my team, but people seamed to love it so much, they encouraged me to share with you.<p>I do understand that workflows in each bigtech company is different, so what worked for us !-&gt; will work for you. So if you are interested in using this or have any question, please feel free to reach out, open issues and prs.<p>lets make AI slop inevitable! <a href="https:&#x2F;&#x2F;github.com&#x2F;Alcray&#x2F;SlopeAutoAcceptor" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Alcray&#x2F;SlopeAutoAcceptor</a>

[DevOps] Launch HN: Minicor (YC P26) – Windows desktop automations at scale Hey we’re Faiz and Saheed and we built Minicor so AI companies who need to integrate to desktop systems with no API can quickly build scalable desktop RPAs. Demo: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=MD0GHZIJ1cw" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=MD0GHZIJ1cw</a><p>We were working on non-RPA integrations when a customer promised to sign a deal in 2 days if we could unblock a sale of theirs that involved integrating with a clinic’s Windows based medical record system. We didn’t know it at the time but it turns out that building desktop RPAs at scale is extremely difficult because scripting is hard (learning the system, defining the automation, UIs changing constantly), orchestration is hard (is the VM up? queuing, parallelizing) and debugging is hard (zero observability, false positives, cascading failures). 30%+ failure rates are not uncommon. At scale we’ve seen cases of failed RPAs leading to thousands of support tickets a month.<p>To solve the problems we were facing, we built an MCP that Claude Code&#x2F;Codex can use to navigate a virtual machine running desktop software with Python to create RPA workflows. The RPA workflows run as Python scripts for speed, cost, and determinism. These workflows can be triggered by API following any input&#x2F;output schema specified, with video replays and logs stored with each run. The MCP can debug RPAs and make changes to the underlying code, all of which are version controlled. We also built tools for cloning VMs for parallelizing RPAs, and handling 2FA&#x2F;OTP challenges. Plus since workflows are code based: we were also able to add triggers for Slack notifications, human-in-the-loop steps, or call an LLM to verify the state of a VM by passing a screenshot.<p>Would love to hear your feedback and if you have any RPA horror stories!
