The Local-First Agentic Identity & Security Layer

Visit nucleusos.devAlternativestop 20% of February 2026

What it does

Nucleus is the local-first security and identity layer for the Agentic Age. It gives AI agents a persistent brain that syncs Cursor, Claude, and Windsurf into one sovereign identity. No cloud required. Features: 🛡️ Hypervisor: Intention-aware resource locking and audit trails. 🧠 Engrams: Git-native long-term memory that lives in your project repo. 🔄 Recursive Mounting: Orchestrate complex tool meshes (Stripe, Postgres, etc.) instantly. Stop repeating yourself. Give your agents a brain.

    ht-mcp – a Rust MCP server of headless terminal for agents2025 · github.com · ▲25

    We built a Rust MCP server, which wraps the excellent headless terminal (HT)[1] to makes it available for agentic coding tools. Most agentic coding tools struggle with blocking, interactive terminal tools (all the boilerplate generator, infra CLI tools etc). This is because many existing CLI dev tools are built for humans and require interactive input. We built this so agentic coding tools (Claude Code, Cursor, Memex, etc) can “see” and “interact” with terminals exactly like humans do. In our demo video [2], you'll see it operating vim/emacs just as a human would - selecting options,…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

  • Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
