Show HN: Brew doctor` for Skills and MCP loadouts Recently, I've had agents reach for the wrong skill or tool. This tends to happen in the middle of longer reasoning chains, which frustratingly means lots of chatter polluting the context before a correction can be issued. To chase these issues down, I built `drskill`: a CLI tool that checks for conflicts and security issues among your agent's Skill and MCP loadout. In addition to spotting conflicts that might trip up your agents, security alerts were added as well. Did an MCP provider silently add a tool due to a supply chain attack? Running `drskill` on bootup or during CI will flag those changes. `drskill` works without access to an LLM, though connecting it to one will yield better conflict reports and allows for suggesting alternate, non-clashing descriptors. A ledger is maintained globally and locally, tracking acknowledgements and preferences. This is the type of tool that heavily benefits from contributions (your loadout...

Show HN: LectureToBook – Turn Videos into a PDF/ePub Lecturetobook takes a video presentation and turns it into an editable document, with photos, diagrams, etc. extracted from your slides. I came up with this idea because I was enrolled in an online course and it was all videos. I spend all day long on the computer for work, so the last thing I want to do after work is spend more time staring at a screen. I wanted something that could take those videos and turn them into a readable format. The most difficult part was detecting what frames in the video are slides, and extracting from those what is useful content to add to the document. I didn't want to just stick a screengrab of the slides in the text, I wanted it to read like an actual book, so it uses an AI model to take from the slides what is useful and ignores what is just repeated in the transcript. Here is an output sample from an NIH video: https://ift.tt/tTamYrX Feedback welcome! This is my first side-project that has ma...

Show HN: PostgreSQL course with database running in your browser I wanted to brush up my SQL skills and was looking for an online course that included a live DB. Most PostgreSQL courses require you to create an account or pay. This is probably because they have to bear the costs of running a full server-side database. So I created learnpg.xyz, a collection of PostgreSQL SQL exercises that run client side. Sharing here because it might be of use to people! https://learnpg.xyz July 19, 2026 at 08:58PM

Show HN: Lific: Issue trackers should be simple, right? I built Lific because I direct AI coding agents on largish projects and needed somewhere for project state to live that isn't markdown files in the repo. When I was begging to work on long horizon ideas, I started on Linear, but my agent files issues faster than a human does, and I hit their limits and pricing wall almost immediately. Then I self-hosted a popular open source tracker which meant running its 13 containers, and its MCP integration was 30k tokens and I got so fed up that I eventually removed it and went back to .md files for a few weeks. Lific is the opposite shape of most of your self hosted server issue trackers: It's a single Rust binary that uses SQLite, and it has an optimized MCP server built in. Web UI is also included integrated directly into the binary. The simplicity is meant to only apply to the size and the ease of installation. The web UI is fully fleshed out with all of the UX you would expect fr...

Show HN: Proton – A Pure Go, Immediate-Mode GUI Library (Zero CGO) Hi everyone, I’ve been building Proton to solve a specific pain point in the Go ecosystem: building native GUIs without the "web dev" trade-offs or CGO complexity. If you’ve tried to build desktop apps in Go, you’ve likely dealt with the frustration of CGO dependencies, bloated build pipelines, or feeling like you’re just writing a thin wrapper around a browser. Proton aims to fix this with a clean, pure-Go approach: Zero CGO: Cross-compile to Windows and macOS seamlessly from any machine. Immediate-Mode API: No setState, no complex component trees, and no XML. You just write your draw function, and it runs every frame. API Immunity: The public API is shielded from the underlying rendering engine (built on top of Gio). If the backend changes, your code remains untouched. Full Feature Set: Includes inputs, lists, overlays, alerts, and 46 built-in themes (or easy custom hex-code styling). It’s currently in devel...

Show HN: QBasic Gorillas (Repeeled) I've found the most engaging way to practice techniques for AI-assisted development and test models is to build fun side projects in vanilla JS.

A bit of extra camera snazz as well. https://ift.tt/nlTV8xQ July 16, 2026 at 09:34PM

Show HN: BeePub – A reading-first alternative to Calibre-Web I've used Calibre's content server and calibre-web, and for actual reading I was on Calibre + Apple Books. It got the job done, but it never felt smooth — so I built my own, working with Claude Code. It's fully compatible with Calibre — that's how I run it myself: my books still live in a Calibre library, and BeePub just points at it and stays in sync (read-only; Calibre remains the source of truth). Same as calibre-web. I've put a lot of work into CJK / Traditional Chinese support (including vertical text), and into manga EPUBs. There's also a native app built with Capacitor, currently on TestFlight (iOS). It also speaks OPDS and KOReader progress sync (kosync), so it plays nicely with e-ink readers. If you're curious, play with it at https://demo.beepub.app (login: demo / demodemo — the data resets every 6 hours). This is a project I dogfood every single day, so expect it to keep getting update...

Show HN: Quantum hardware now fault-tolerant without extra engineering Before you say it's impossible, please go try. --- CIQA, an analytic Quantum Error Correction code, is now freely accessible on GitHub alongside CIQS, the 'million-qubit compiler'. Here's a brief overview of the stack: 1. CIQS - An analytic circuit transpilation pipeline (no heuristics, no tunable parameters). It passed the full IBM Benchpress transpilation suite (892/892 tests) in 75 minutes on older hardware, while Qiskit took 17+ hours. It scales linearly to 1M+ qubits on the same harness (that is one million and above). 2. CIQA - An analytic 1:5 QEC that enables full active computation and complete Pauli correction at depth on existing hardware. On real quantum hardware, it delivered a mean fidelity improvement of up to +0.832 over bare qubits. On the same hardware, it successfully ran the full Hayden-Preskill black hole circuit, preventing early decoherence, and enabling the first observation of...

Show HN: Reviving my 2001 college band with AI 25 years ago, I joined a band called Fading Maize at Ripon College in Wisconsin. We did what we could with what we had. We recorded 3 albums over the next 3 years and played at as many bars and coffee shops as we could. We built a website with Microsoft Frontpage. Then we all went our separate ways, got married, had kids, focused on other things. Earlier this year I had the idea to approach the lead singer who wrote all of the lyrics and melodies to the stuff we played back then and wanted to "reimagine" everything in 2026 using AI. That's the project I want to share here! The site has a before/after player where you can flip between the original dorm-room recording and the 2026 version mid-song without losing your place, so you can hear exactly what changed. The original 2001 website is preserved and browsable at https://ift.tt/q5u7PcD , rough edges intact. On the AI question, since it's the elephant: the songs, lyrics,...

Show HN: Reverse-engineering web apps into agent tools Hey HN! We built a browser-based agent that runs inside an authenticated web app, watches how the app calls its own APIs, and automatically turns those into agent tools. You can think of it as an auto-generated MCP server that self-updates as the host app changes. The result is a skilled AI assistant that actually integrates deeply with any product (not just chat and RAG) with minimal effort. Check out these short demos below that show the agent in software you're probably familiar with: - Jira: https://ift.tt/1sG6DN5 - Spotify: https://ift.tt/xrzjRZc - Hacker News (lol): https://ift.tt/i5pYFQb - Full Demo: https://ift.tt/XM05xJ3 As you can see in the examples, you can do way more (and faster) than what you normally would be able to via point and click. And we never even touched the source code of these products! Why do this? In an ideal world, every application has an MCP server or an easily-digestible API available fo...

Show HN: Book Bounce – Bedtime story helper for parents I built a helper for my son's story times. After a few months of reading to our son we couldn't remember what books we read and when, we realized that our personal library had hotspots, and we were going to need the option for variety when the time came to choose bedtime books. This app gives my wife and I a rotation for our physical books based on the last time they were read and the frequency setting on each book. It also throws in other children's books on OpenLibrary to read to him. We've found some new favorites from this feature. Reading activity is logged as well. We've used it to track his 1000 Books Before Kindergarten progress. Supabase stores a pool of OpenLibrary ebooks to randomly suggest to users. OpenLibrary's API is used as a book data source. Everything else stays local to your device. TLDR: App that helps parents rotate through story books, suggests ebooks on OpenLibrary, tracks reading ac...

Show HN: Pulpie – Models for Cleaning the Web Hey HN, I'm Shreyash, founder of Feyn. We built Pulpie, a family of Pareto optimal models for cleaning the web. Pulpie strips boilerplate (ads, footers, sidebars) from raw HTML and returns just the main content as HTML or Markdown. We match SOTA extraction quality while being 20x cheaper. Cleaning 1 billion webpages costs $7,900 with Pulpie versus $159,000 with Dripper, the current leading extractor. The gains come from architecture. Today's leading extractors are decoders that generate output one token at a time. Each step reads the full model from memory to produce a single token. Conversely, Pulpie models are encoders. They run one forward pass over the full input HTML and label each block as boilerplate or content. As a result, Pulpie is compute-bound while decoders are memory-bound. Cheaper GPUs have relatively more compute than memory bandwidth. This makes Pulpie easy to run optimally. Here's Pulpie and Dripper cleaning th...

Show HN: Ultracodex – Run Claude Ultracode Dynamic Workflows with Codex Agents Claude Fable has been incredible, however the plan usage runs out too fast, especially if you use ultracode mode (Claude Code's workflow feature, where the model writes small JavaScript programs that orchestrate subagents) and let the agents go brrr. I want Fable to focus on high-value tasks such as planning or verification, and not burn tokens on mundane implementation work. So I built ultracodex, an engine that spawns codex agents to complete the same ultracode workflows and hand off seamlessly to and from Claude. It runs the same workflow scripts that Claude writes. I designed this tool for anyone owning both Claude and Codex subscriptions or anyone who enjoys Fable and wants to make the quota last. This tool is in early days but I am very excited about the potential. I think it’s also a great “loop engineering” starter pack for us because 1) Claude is great at writing loops and 2) ultracodex runs the...
