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 …
Show HN: Demucs music stem separator rewritten in Rust – runs in the browser https://ift.tt/jVnxb96
Show HN: Demucs music stem separator rewritten in Rust – runs in the browser Hi HN! I reimplemented HTDemucs v4 (Meta's music source separation model) in Rust, using Burn. It splits any song into individual stems — drums, bass, vocals, guitar, piano — with no Python runtime or server involved. Try it now: https://nikhilunni.github.io/demucs-rs/ (needs a WebGPU-capable browser — Chrome/Edge work best) GitHub: https://ift.tt/0qVo8Xj It runs three ways: - In the browser — the full ML inference pipeline compiles to WASM and runs on your GPU vi…
Show HN: CrowPay – add x402 in a few lines, let AI agents pay per request https://ift.tt/XdKpgYv
Show HN: CrowPay – add x402 in a few lines, let AI agents pay per request Hey HN – I've been building in the agent payments space for a while and the biggest bottleneck I see isn't the protocol (x402 is great) — it's that most API providers have no idea how to actually integrate it. The docs exist, the middleware exists, but going from "I have a REST API" to "agents can discover and pay for my endpoints" still takes way more work than it should. CrowPay fixes that. We integrate x402 payment headers into your exi…
