Agent Overwrite Grader

Paste your git log; the grader lists every file two sessions (two authors, or two branches) changed less than an hour apart, ranked by how often it happened. Those are the edits most likely to undo each other when Claude Code, Codex or a teammate work in parallel. It runs entirely in your browser: nothing is uploaded, no signup. Try the sample log to see a report in one click. A README badge shows the count for a public GitHub repository.

ssh zydra.sh, a GPU Linux desktop in your terminal, with Doom

ssh zydra.sh There's no sign-up or anything, and you get a 15-minute of a graphical Linux VM drawn entirely in your terminal. It has a browser, an editor, and it runs Doom. It works best in Kitty or Ghostty. WezTerm and Konsole also work, as well as Sixel and iTerm2 terminals, though with less detail. Text-only terminals support non-graphical apps: shells, editors, and other TUIs. Why? For a few months I ran coding agents in tmux on a VPS over SSH, and it sucked. I couldn't paste images, scrolling broke and I didn't wanna figure out why, I had no notifications for when an agent finished, I couldn't see browsers agents opened to smoke-test, logins drifted between my laptop and the server, I couldn't check in from my phone, and to know what an agent had done five minutes ago I had to read through opaque chunks of tool calls. These issues added up and had me in a limbo: They made my setup bad enough to annoy me every day, but not quite bad enough to stop my real work and fix it. How it works: Zydra is a custom (Smithay-based) Wayland compositor in a microVM with an AMD GPU, implementing a series of terminal protocols that solve many issues but are often ignored: Kitty graphics for windows, OSC 52 for the clipboard, images included, OSC 9/99/777 for notifications, SGR mouse for scrolling and clicks. VNC is limited to sending pictures of the screen and diffing frames to find what changed. In Zydra, apps directly tell the compositor what changed, and terminal text is sent as text you can select and copy natively. The browser is a WebKit build that delivers frames to the compositor as DMA-BUFs without a readback, and agents drive it through Playwright. Alt+P is sort of like Raycast: browse apps, linked GitHub, websites, and SSH targets from it. You can watch the desktop at any point in time and rewind to periodic snapshots. To achieve this, the desktop records into a timeline file, a kind of structured video, and the VM takes snapshots along it. You can traverse back like a livestream to see what happened while you were away, then restore or fork the whole machine from that point. Agents can mark points on the timeline and checkpoint the whole machine before risky changes. Other things to try: ssh -t zydra.sh dino # the Chromium dino game via SSH tar -czf - -C ~ .claude .claude.json | ssh -T zydra.sh upload # bring your configs (includes your Claude login) ssh -o ObscureKeystrokeTiming=no -A zydra.sh # lower latency & forward your SSH agent ssh -p 443 zydra.sh # connect from a corporate firewall sshfs zydra.sh: ~/zydra # paid accounts: mount your home Everything runs on one dedicated server with one AMD iGPU, so there are 12 slots. When they're full you wait in a queue and can play Chromium's offline dino game. The paid plan is $40/month (+ tax): 8 GB RAM, 4 vCPUs, 80 GB disk, GPU access, with no time limit and a 3-day money-back guarantee. I'll be around all day to answer questions.

Muxer – Control cmux terminals from Android

Hey HN! As an avid user of cmux ( https://cmux.com/ ), I wanted a way to control terminal and agent sessions from my Android phone, so I built Muxer. The app talks to a tiny relay over HTTPS, that then talks to cmux through its local socket, and gives you to ability to: - Answer agent permission requests, questions and plans from a notification - Reply to Claude Code, Codex and Pi chat sessions with text, voice, @ file mentions and photos - Receive all cmux notification, with inline replies, bubbles and background delivery. - Use a live terminal with sticky modifier keys and local scrollback - Share text and links from any app to an agent - Organize workspaces - Manage cmux Cloud VMs and automations - Lock the app with your fingerprint, face or screen lock Enjoy, and let me know what you think!

Perch, a calm Mac app for juggling Claude Code sessions

I'm an engineer, but I also hate using tools that make things overcomplicated. It's also tough with the new pace of AI-driven development to really get into the flow state, and maintain (still needed!) focus on 1 thing. So I built a tool that I actually want to use every day. Curious if others would find this useful, too, or have any feedback? Like if it's nearly there, what changes would make this a win for your workflow? Details: - It's a Mac app (Apple Silicon) that runs your Claude Code sessions side by side. Each piece of work gets a "context" with its own session, next steps, status, PRs, and links. - The dashboard groups contexts by whose move it is: yours, waiting on a reviewer or teammate, Claude working, or idle. You get a notification when a session needs you or a PR gets review comments. - For non-engineers, there's a Chat view instead of the terminal, a guided Claude Code install, and folder pickers instead of paths. Engineers can stay in the real Claude Code terminal. - It runs the actual claude CLI, and sessions keep running if you quit Perch. You can also import your existing Claude Code sessions. - Everything stays on your Mac. There's no account and no analytics, and crash reports are opt-in.

Codex quota tracker Garmin watch face

I think I'm not alone with that quota-based AI subscriptions have given me a new hobby: checking how many tokens I have left. How’s my 5-hour and 7-day limits? When’s the next reset? Can this task wait, or should I use a smaller model? I used to check my Garmin for steps and heart rate. Now I’ve built a watch face to track my AI usage limits and reset countdowns too. The idea was to make it very easy to add usage data from other vendors as well.

Multipeer, a multiplayer infinite canvas for people and their agents

I'm building Multipeer, a desktop app for running agents, tools and working wth teammates on one shared canvas. I often have several agent sessions open at once, but they're all scattered across terminals. It was also hard for my co-founder to see what my agents are doing or jump in to work together. So We built the solution to our own problem. And now we're releasing it to the world. It's a macOS app for now (soon on Windows and Linux). You can invite your teammates over a local network or over the internet. They can follow your view and, if you allow them, they can also take control of your terminal and claude code/codex sessions. The app is still early, and I'm also releasing the iPhone/Android app soon to remotely control everything on your canvas. I'd would like to get feedback from the HN community! If there's any features you'd like to see, please contact me via: shyam@multipeer.sh, we build really fast. I'd love to talk to everyone of you and work on your feedback! Thanks!

Mnemolith – AI coding memory that goes stale when your code changes

Hi HN, I'm Anish. I built Mnemolith because the AI coding tools I use (Claude Code, Cursor, Codex) either forget my project between sessions, or remember things that quietly stopped being true. Tell the agent "we use Postgres", migrate to MySQL two weeks later, and it keeps building on the old fact. How it works: - It's an MCP server, so Claude Code, Cursor and Codex share one memory per project (keyed by the git repo). - When the agent saves a memory, it can link it to the files it depends on. Mnemolith stores each file's git blob hash. If the file's contents change (committed or not), the memory is set aside and flagged for review, so the agent stops relying on it. - A local dashboard shows what the agent remembers, where each memory came from (tool, session, file versions), and its full history. You can confirm a memory is still true, or retire it and say what's true now. - Contradictions are judged by the agent, not by a similarity threshold. In my calibration, "we use Postgres" vs "we migrated to MySQL" only scored 0.30 similarity, so a threshold can't tell a contradiction from an unrelated fact. - Current memories can sync into a managed section of AGENTS.md / CLAUDE.md, so they get reviewed in PRs. Under the hood it runs on an engine I wrote from scratch in Java: a Redis-compatible server with a built-in memory model and an HNSW vector index. Embeddings run locally (all-MiniLM-L6-v2). Everything stays on your machine. It's early (v0.2.1). There's no team sync yet beyond the AGENTS.md/CLAUDE.md files, and it needs Java 11+ (it downloads a private copy if you don't have one). I'd really like feedback, especially from people running coding agents on real codebases. What does your agent keep getting wrong?

Sonah, code reviewer that reads your agent's session, not only the diff

Hey Everyone, After getting frustrated by Claude rewriting key functions and still making the test pass, was tinkering around with a review tool, that would track the assumptions and decisions the agent took, without me digging through the entire session. So ended up building Sonah. Sonah is basically a code reviewer that not only reads the code and diff but also the agent session that wrote the code, to understand the assumptions, and decisions your agent took along the way. And highlight important parts of the code that need your attention. Sonah uses your existing claude code/codex subscription (claude preferred for higher context window). You can try using below: npm install -g getsonah sonah doctor cd your-project && sonah review --format html --output ~/review.html

Codex Co²:让多人共享同一个 Codex 会话,一起推进工作

阮老师好,自荐一个开源项目 「Codex Co²」( ): 让多人共享同一个 Codex 会话,一起推进工作。 解决的痛点是,Codex 官方虽然也提供了会话分享功能,但只可以把只读的历史快照发给别人。但如果对方看完后想继续追问、补充信息,或让 Agent 接着排查的话,就满足不了,需要一种能持续交互的协作方式。 Codex Co² 通过生成邀请链接,让一方得以在官方 Codex Desktop 中继续工作,另外几方则可以通过浏览器加入所选会话,查看已有上下文,并向同一个 Agent 发送消息、跟进后续结果。 一个典型场景就是运营与研发的接力排障: 运营先让 Codex 分析用户反馈的日志,得到初步结论,再将这条会话分享给研发。研发加入后,可以直接查看前面的日志分析过程,补充代码背景、追问可疑线索,让 Agent 继续定位问题。运营也能在同一条会话中补充用户信息、跟进排查进展。 主要特点: 共享持续进行的会话:加入后可以继续交互,后续消息与 Agent 回复持续同步。 协作者只需浏览器:打开邀请,经分享者批准后加入,无需安装应用。 由分享者控制范围:只共享选中的会话,可移除成员、结束共享,也可开启逐条消息审批;原生工具审批仍在分享者的 Desktop 中处理。 中文演示视频

Developer OS

Claude Code forgets everything between sessions, and its defaults are not a careful engineer's habits. developer-os is a free, MIT-licensed plugin that fixes both. Your agent searches an Obsidian vault before work and captures decisions into its inbox while it works; you approve what stays. Rules load in every session, skills cover specs, reviews, audits and PRs, and hooks ask before installs or force pushes. Plain Markdown, no server, no telemetry.

Islet

Islet turns your Mac's notch into a tool built for developers. It changes with the app you're in: AI commit messages and git status in VS Code, localhost to your phone (or a public link) in Chrome, and `islet run` alerts in Terminal. When Claude Code or Codex needs your approval, a hand pops up in the notch with a chime. You also get PRs with CI status, ports and your Claude usage at a glance. Music, meetings, timer and AirDrop too. ~25 MB, 0% idle CPU, no account, free.

Peras – Pause Claude Code and Codex before they burn your weekly limit

Hello HN! Today I am presenting you with Peras, the tool which governs your Claude Code and Codex usage, and enforces limits. I built it because I got tired of constantly having to spam /usage to check my usage, and decide if a task is worth risking the agent running out mid-task. Peras enforces a limit with 2 main tiers. At 75% weekly usage you will get a notification, and at 90% Peras will automatically pause the agent. These limits are the default and they are customizable to your own liking. You may ask "how does it know my usage in Claude Code or Codex?" Well, it's pretty simple. Peras gets the Claude Code usage % from the status line, and Codex's one comes from its local app-server. The "pause" Peras executes is a hook that refuses the agent's tool calls and ends its turn. A new feature I implemented is one that makes agents aware of their own usage. When you send your prompt, Peras attaches the usage %. It sends it at the start of the session, then again at 50, 75, 90 and 100%, or if a reset is coming in 30 minutes, so the agent can hurry up and actually capitalize on the remaining usage, if any. Just to clarify, this feature is informational and the pause is what enforces the limit. Before I switched to native SwiftUI, I used SwiftBar. The problem was that for the mascots patrolling their usage bars, I had to re-encode every menu image 8 times a second! There was also stuff SwiftBar wasn't capable of, like the menu being able to appear over fullscreen apps, pinning it as a floating panel, etc. What is the difference between the free and paid version? Well, it is MIT, first of all. The CLI, the hooks, the SwiftBar menu, and the app's source are all on GitHub, but building the app needs macOS 13+, Node 18+, "xcode-select --install" and then finally "npm run build:app". The €4.99 buys you a signed copy which is notarized by Apple, with updates included. The guard works with no menu at all. To install, just run: npx peras-cli setup npx peras-cli codex setup And now we get to the limits part. For now it's subscription plans only, and when running "claude -p", the pause uses the last interactive reading, so it can come late. Also I feel I have to mention that the guard rail is not a security boundary. It runs inside the agent. The menu is macOS only. The CLI and hooks pass tests on Linux in CI, but I don't use them there day-to-day. Last thing before I end this post, I would really appreciate feedback from you, whether install worked for Codex users, whether you have encountered any bugs, or whatever you feel like sharing.
