Show HN: Kintsugi – a local-first safety net for AI agents and humanshttps://github.com/arrowassassin/kintsugiAI coding agents now run real shell commands on your machine — rm -rf, git push --force, DROP TABLE, dd, writes straight to disk. Almost always that's fine. The one time it isn't (a hallucinated path, a prompt-injected instruction, a confident wrong guess) there's no undo and you find out after.Kintsugi sits between the agent and your system. It catches the dangerous command before it runs, explains it in one plain sentence, makes destructive actions reversible with a snapshot, and writes every command every agent ran to an append-only, hash-chained log you own. Local-first: no cloud, no account, nothing leaves the machine.It's not only for AI. A passive bash/zsh recorder (no agent involved) puts every command a person runs on the same tamper-evident log and snapshots the destructive ones just-in-time — so `kintsugi undo` rolls back a DBA's fat-fingered rm -rf or clobbering overwrite the same way it rolls back an agent's. On a managed host you can seal the settings behind an admin passJun 16, 2026 5:00 PM

Show HN: Memento – Self-hosted agentic search and LLM wiki over your emailhttps://news.ycombinator.com/item?id=48557937Our email inboxes carry multiple decades of messages (100K-500K). This is a good proxy for all the important things that happened in your life, the projects you have done and the people that you have connected with. With the chronological view of messages in the inbox, these details remain hidden. What if we could turn this archive into a personal wiki that you can search and curate? That is Memento.For the information architecture of such a wiki, Memento takes an opinionated view of creating four high level dimensions - People (like a CRM view of your contacts), Projects (life events that are bounded by some start and end dates), Concepts (evergreen topics) and Newsletters.Inboxes group messages by sender address, so the same person shows up many times across work, personal, and alias addresses. In the People dimension, Memento resolves all of that into one canonical person using deterministic algorithms and brings the people who are related to that person through graph algorithms.

The ongoing debacle of hiring a fake coworkerhttps://news.ycombinator.com/item?id=48557755so, just had a guy ousted today in part due to my own judgment, as well as my boss'.this guy passed the interview rounds cleanly with decent answers -- I was in one, and I suspected something was "off" about him, but was willing to go ahead.after a couple months it becomes apparent this person is not really as inquisitive or critical as I'd like. they ask no questions, need no clarification, are silent in meetings.once it comes time to look at PRs, it's incredibly apparent it's LLM slop. not even GOOD slop -- lots of things outright broken, non-conforming frontend design, messy and redundant code. you can imagine.the person also cannot seemingly answer questions in sync. everything gets delayed, seemingly processed through the mouthpiece of AI. watching them live code is a mess. they seemingly have no idea what to do, until the AI instructs them. sometimes I even see them typing my questions in. (by the way, this was a SENIOR dev role.)so, needless to say, the person is gone now after Jun 16, 2026 4:24 PM

Show HN: git-lrc – Free, Micro AI Code Reviews That Run on Git Commithttps://github.com/HexmosTech/git-lrcHi HN, I'm the author of git-lrc, would appreciate some feedback from the communityLast year my team started using AI coding tools more heavily, and we found ourselves generating tons of code, but spending less time looking at the stuff that's been generated.We felt like we were losing a bit of grip/understanding of what we were building. Regressions occasionally slipped through. Sometimes changes made it all the way to production only to be reverted later.We tried several AI code review tools, but most operate at PR time. That felt too late. I wanted review to happen while the implementation was still fresh in the developer's mind at a team level (soft enforcement). I also wanted to emphasize responsibility for keeping prod stable with each individual engineer.So I built git-lrc.When you commit, git-lrc opens a review UI with your diff. It summarizes what changed, points out things that deserve a second look, and lets you quickly jump through the important parts of the change.Over timJun 16, 2026 2:04 PM

Show HN: Satd – a Bitcoin full node in Rusthttps://github.com/epochbtc/satdI'm Ben, and I've written a modern, independent implementation of the Bitcoin protocol in Rust. The primary problem I wanted to tackle was monoculture: the Bitcoin network and community has been based on a single C++ implementation for 15 years, a descendant of the original Satoshi-authored codebase. This codebase and the small Core committee are a single-point-of-failure, and is a potentially attractive target for those who would seek to damage or disrupt the network.On top of that, while the Core team has done a great job at stewarding and improving the codebase, it can't help but be a big, complex tree of largely legacy C++. I wanted something modern, easier to maintain and with batteries included:- Native TLS (including mTLS) out of the box- Built-in (optional) API services for Electrum (based on electrs) and Esplora (no sidecars or separate services needed to run a wallet backend)- Atomic indices with a single RocksDB data store (address index can't lag core block index, for exampJun 16, 2026 1:47 PM

Show HN: Babysit – let coding agents operate a TUIhttps://github.com/yusukeshib/babysitI've been trying to automate my work recently, but I ofeten encounter the situation where agents needs human intervention to complete the task. So I made a simple command that wraps a TUI called babysit that has a terminal emulator inside using pty. Agents can start commands in background, and they can ask human by attaching the TUI on a new tmux pane when human intervention is needed, or they can operate the TUI with screenshot/send/expect/wait commands. So far, I really like using it, and I wanted to share it here.https://github.com/yusukeshib/babysitJun 16, 2026 12:53 PM

SMS OTP sessions for AI agents and CI testshttps://agentsim.devHey HN — I built AgentSIM. It started because I wanted my agents to get through SMS phone verification and kept hitting the same wall: the cheap programmable numbers everyone reaches for (Twilio and friends) are VoIP, and strict services reject VoIP at carrier lookup before they even send the code.So I went down the rabbit hole of "how do I get a number that passes." The uncomfortable thing I learned: there's no cheap shortcut. Carrier lookup checks whether a number is a real mobile SIM, and programmable numbers — VoIP or the "fixed-line" CPaaS kind — aren't one. Only real SIMs pass, and those are expensive and painful to source at scale. Anyone selling you cheap "numbers that verify anywhere" is either lying or about to get their pool burned.So I built the honest version instead. AgentSIM gives an agent (or a CI job) an ephemeral programmable US number that receives SMS OTPs over a REST API, SDKs, or an MCP server. It's blunt about where it works: auth you own or control (your own appJun 15, 2026 10:40 PM

Show HN: Simple, lightweight, modern, turnkey, Java web server libraryhttps://github.com/Petersoj/jetJet is a simple, lightweight, modern, turnkey, Java web client and server library.Jet offers four modules: Common, Server, OpenAPI Annotations, OpenAPI Annotations Plugin, and Client.Jet is a wrapper around the excellent Jetty web client and server library. Jetty provides the battle-tested low-level protocol handling, while Jet focuses on providing a modern and consistent interface with superb documentation and an amazing developer experience.---I built this Java library to fill a hole in the Java web server library ecosystem. Javalin got me 90% of the way there, but requires the Kotlin dependency and lacks header models and exhaustive KDocs.

Ask HN: Specialization to stay relevant in the age of AIhttps://news.ycombinator.com/item?id=48544117I've had a lot of discussions with peers about the possibility of us being replaced via ai agents and how to stay relevant, given a future where AI intelligence keeps improving to the point of being capable of replacing potentially any job.My personal strategy is specialization, because I've noticed that I cannot work with AI in hard domains that I haven't got a background in. For example, I've tried to use claude opus to understand a phd thesis in quantum physics from a friend. My background is in engineering and later compilers/static analysis. Despite opus helping a lot to give me the high level idea behind it, I could see a few problems with my lack of background: - I couldn't verify if opus was right or wrong in its explanations - Even when asking the AI to simplify explanations, there was so much prerequisite knowledge I needed to absorb that there was little point to bother with its output - It was very hard to collaborate with the AI to understand what predictions can be made fJun 15, 2026 5:02 PM

Show HN: CriteriaBot – A Universal Customizable Classifierhttps://criteriabot.io/I needed a classifier for nuanced, subjective buckets that fell outside of typical ML use-cases (e.g., "is this a spoiler?", "is this factually correct?", "is this user being mean?"). I ended up really happy with the architecture I built to solve it, so I rolled it out as a standalone API and service called CriteriaBot.WHAT IT DOES:You give it content and plain-English criteria. It gives you a true/false verdict on whether the content meets those criteria.HOW IT WORKS:In addition to a traditional classifier, the classification request is routed through a pool of small, open-weight LLMs to achieve a consensus verdict.I built a pre-vote factorization machine that selects a sub-pool of LLMs optimized for signal strength based on the embedding of the subject/category. A second factorization machine then reads the votes and the embedding to arrive at a single verdict. That verdict is dynamically modified based on the user's history of agreement/disagreement with the models in semantically sJun 15, 2026 2:48 PM
