Show HN: mTile – native macOS window tiler inspired by gTile https://ift.tt/DX5LknG
Show HN: mTile – native macOS window tiler inspired by gTile Built this with codex/claude because I missed gTile[1] from Ubuntu and couldn’t find a macOS tiler that felt good on a big ultrawide screen. Most mac options I tried were way too rigid for my workflow (fixed layouts, etc) or wanted a monthly subscription. gTile’s "pick your own grid sizes + keyboard flow" is exactly what I wanted and used for years. Still rough in places and not full parity, but very usable now and I run it daily at work (forced mac life). [1]: https://ift.…
Show HN: Mantle – Remap your Mac keyboard without editing Kanata config files https://ift.tt/zpB83CT
Show HN: Mantle – Remap your Mac keyboard without editing Kanata config files I built Mantle because I wanted homerow mods and layers on my laptop without hand writing Lisp syntax. The best keyboard remapping engine on macOS (Kanata) requires editing .kbd files which is a pain. Karabiner-Elements is easy for simple single key remapping (e.g. caps -> esc), but anything more wasn’t workin out for me. What you can do with Mantle: - Layers: hold a key to switch to a different layout (navigation, numpad, media) - Homerow mods: map Shift, Control…

Show HN: Kybernis – Prevent AI agents from executing the same action twice https://ift.tt/pqeS25n
Show HN: Kybernis – Prevent AI agents from executing the same action twice AI agents increasingly execute real system actions: issuing refunds, modifying databases, deploying infrastructure, calling external APIs. Because agents retry steps, re-plan tasks, and run asynchronously, the same action can sometimes execute more than once. In production systems this can cause duplicate payouts, repeated mutations, or inconsistent state. Kybernis is a reliability layer that sits at the execution boundary of agent systems. When an agent calls a tool: 1…
Show HN: Athena Flow – a workflow runtime for Claude Code with a terminal UI https://ift.tt/F6X4Gy1
Show HN: Athena Flow – a workflow runtime for Claude Code with a terminal UI Athena Flow is a workflow runtime that wraps Claude Code via its hooks system. It receives the event stream, applies workflow and plugin logic, and renders everything in an interactive terminal UI with a live event feed. Instead of writing throwaway prompts or one-off scripts to automate complex multi-step tasks, you define a workflow once — with prompt templates, loops, plugin bundles, and structured lifecycle hooks — and run it against any project. The first workflo…
Show HN: I put HN discussions next to the article where it belongs https://ift.tt/DbqaQIL
Show HN: I put HN discussions next to the article where it belongs It it always bugged me when I read or share an article, the discussion lives separately from the article. I imagined being able to add Google-Docs or Notion style comments on any website. We save a snapshot of the website and allow adding discussions that live side-by-side and directly reference parts of the article. HN articles are automatically indexed in https://cooo.link/hackernews and you can add any website, PDFs on https://cooo.link/ Built with SvelteKit, SingleFile(for …
Show HN: Agent Action Protocol (AAP) – MCP got us started, but is insufficient https://ift.tt/JtuWnxA
Show HN: Agent Action Protocol (AAP) – MCP got us started, but is insufficient Background: I've been working on agentic guardrails because agents act in expensive/terrible ways and something needs to be able to say "Maybe don't do that" to the agents, but guardrails are almost impossible to enforce with the current way things are built. Context: We keep running into so many problems/limitations today with MCP. It was created so that agents have context on how to act in the world, it wasn't designed to become THE standard …
