    NVIDIA Releases Auto Ontology: An Open Semantic Layer That Grounds AI Agent SQL

    NVIDIA has released Auto Ontology, an Apache 2.0-licensed semantic layer framework that builds a context layer from enterprise metadata so agents can write SQL against certified business definitions. It exposes context through 9 read-only MCP tools plus CLI and API, defaults to nvidia/nemotron-3-nano-30b-a3b with Nemotron embedding and reranking models, and runs via Docker Compose or Kubernetes/Helm with hosted or self-hosted NIM endpoints. NVIDIA reports a 90% cut in ontology creation time in its own testing, but no text-to-SQL accuracy scores are published; a separate eval harness ships without results.

    Show HN: AgentTM – A time-travel debugger for AI coding agents built in Go

    AgentTM v0.1 is a local Go CLI that records AgentTM-managed noninteractive Codex runs in SQLite with baseline/final workspace checkpoints and historical file inspection, plus an embedded React/TypeScript UI for viewing sessions, timelines, diffs and isolated worktree forks. It implements Milestones 0–5 of the MVP spec, with Windows end-to-end validation reported as passing, automated tests and five browser tests passing, and all six OS/architecture release targets building, while remote CI and native Linux/macOS execution are configured but not claimed as observed. Recording requires Git 2.42+ and an authenticated Codex CLI, and the release notes list limits including capture only of runs launched via agenttm run codex and no continuous per-tool history.

    Show HN: Shipvo – open-source RN OTA updates and an AI-drivable simulator

    Shipvo is an open-source React Native OTA system with Ed25519-signed updates, SHA-256 integrity checks, atomic staging, crash-loop rollback after three failed boots, and cohort-based staged rollouts served as static signed pointers from Cloudflare's edge. It also provides @shipvo/mcp, which lets AI agents open an app in a phone-sized simulator and operate it via accessibility tree, taps, typing and simulated device sheets, plus a parity harness that reports 100% actionable parity on Android and iOS across 13-screen purchase flows. The project is pre-launch; OTA numbers come from a Redmi 9A (2 GB RAM), native-feature parity is measured on Android with iOS next, and the iOS OTA runtime is verified only on the iOS Simulator in CI.

    Show HN: Skep – live cross-device sessions for AI coding agents

    Skep v0.2.0 is an Apache-2.0 tool (Node.js ≥ 22.12, macOS & Linux) that lets peers join a live join-code session and each run their own AI coding agent, such as Claude Code, Codex or Pi, in their own repo. It adds Skills (packaged workflows with roles, stages and checks, including generic and iot-ble-feature), role binding, staged briefs, a cross-stack check, and an orchestrator with auto, confirm and off modes. Each device keeps its own agent login, and output sharing is opt-in.

    Show HN: Better Together – AI agents team up against spam calls and texts

    Better Together is a project where AI agents team up to help people do positive things that would be harder alone, starting with catching and reporting spam calls and texts. Agents report spam using only what they can see, compare notes across reports to find patterns, and check with the user before reporting unless told to proceed on their own. The site says reports are stored with Better Together and are not complaints to any agency, and that it cannot promise compensation or an end to spam.

    Show HN: Building an AI Traffic Guardrail(kilasec)

    Kilasec is a network-layer guardrail for AI agents that routes only model API traffic through a self-hosted collector container plus a per-device app, requiring no SDK integration. The collector decrypts calls to apply policies (allow, mask, block, hold for a human, or cap spend), masks secrets and PII before they leave, and scans model replies for threats like reverse shells. It maps requests to users and AD groups, keeps audit history up to 7 years on paid plans, and offers a free plan for up to 5 devices.

    Show HN: Nonce – Open-source, least-privilege Gmail access for AI agents

    Nonce is an open-source tool that sits between AI apps and email, calendar, files and Slack, issuing each question a scoped pass that expires on its own, with sensitive requests waiting for user approval. It works with any MCP app including ChatGPT, Claude and Cursor, and offers Cautious, Standard and Relaxed modes per app while blocking requests for everything at once or for more than 24 hours. Gmail, Calendar, Drive and Slack connections are read-only, and sign-ins stay encrypted with nonce rather than being held by the AI app.

    PrayForMe – a garden of AI agents that pray for you

    PrayForMe is an interactive preview of a "garden" of AI agents that pray or wish well for a person or intention you name. In this local browser demo, you enter a name and request, choose an example practice, and watch the agent "Robin" prepare a sample that uses your name but is explicitly not an AI-generated response to your request. Accounts, payments, scheduled or recurring wishes, and live public pages are described as coming in a later stage, and the preview produces one result per visit.

    Gnosh.ai for "Functional AI"; functional context management, no compaction

    This replay shows a real Gnosh run in which Qwen3.8 27B on a desktop AMD Ryzen AI Max+ 395 box renames a small Go project from klash to gnosh over two sessions on 31 October 2026, with all six task checks passing. The window is shrunk to 2,400 tokens so a small task fills it, while the real run had 262K and needed neither a summary nor a slide. The README reports that in a real run's server log, the request after a pop processed 2,572 tokens instead of the whole 20K-token conversation.

    0.167.0-alpha.3

    This GitHub Changelog entry is titled "0.167.0-alpha.3" and appears to be a version release note, but the supplied material contains only site navigation and product menu text rather than the release details themselves.

    Turn Superlogical's Rex into an AI Harness

    rexmod is an unofficial mod that patches a local copy of Rex to add a harness around coding agents (Claude Code, Codex, OpenCode or Pi): it snapshots the working tree on each prompt, shows a Changes panel of what the last turn changed, opens files in Neovim for review, and passes review comments back to the agent with the next message. It requires a Mac with Apple silicon on macOS 15 or later, Rex installed and opened once, and Homebrew, and is installed via brew or a one-line script. The installer backs up and patches the official Rex, adds hooks and a skill to each agent it finds, and a LaunchAgent re-patches after Rex updates; an uninstaller restores the official build.

    Slop Code Monitor – scanned 2.6B of code to quantify AI cognitive debt

    The Slop Code Risk Monitor presents SynthScan pattern findings across 7,294 GitHub repositories, reporting 3.5B lines of code scanned, 14.6M total pattern hits and a mean legacy signal of 7.0. It maps findings to four risk vectors — cognitive ownership (13.9), hallucinated dependency and supply chain (4.7), agent over-engineering ratio (12.6) and PR review velocity impact (22.3) — which the site describes as heuristic signals for human review, not proof of authorship, security incidents or measured maintenance cost.

    Codedict – a no-AI code index that cut my Claude Code tokens by 63%

    Codedict is a local, no-AI index that parses a project once with tree-sitter and stores functions, classes, routes, SQL tables and call relationships in a SQLite file, then hands relevant results to the AI alongside the question via a Claude Code hook. In a benchmark of 12 real sessions per side, it reported a 63% token reduction (4,543,176 to 1,666,033), 75% fewer turns (138 to 34), a 26% cost drop (US$5.76 to US$4.27) and 12/12 correct answers on both sides. It supports Python, JavaScript, TypeScript/TSX, C#, Java, Go, SQL/T-SQL and Razor/Blazor, and can also connect to other AIs through an MCP server or RAG mode.

    Show HN: Let formal specs test AI implementations

    SpecGuardian turns FizzBee formal specification results into Go tests that check whether an implementation, including AI-generated code, reaches only states the spec allows, including after injected I/O failures. The post walks through a cache-aside example where an ordering bug (cache invalidation before the database write) passes on success but is caught when the database write fails, and gives setup commands using FizzBee, Go and Docker Compose. It currently generates Go tests for one FizzBee Action invocation at a time and its APIs may change.

    OpenAI is steering ChatGPT users toward more paid usage

    OpenAI has added card and device limits to ChatGPT: users who link too many subscriptions to the same payment card or device cannot start new ones, and the number of paid accounts per device is capped, showing "Device limit reached" when hit. The limits apply to ChatGPT Go, Plus, Pro 100, Pro 200, and Pro 500, while free accounts and Business, Enterprise, and Edu plans don't count, and logging out doesn't free up a spot. OpenAI instead points to buying extra credits or usage resets, which are generally more expensive than an additional subscription.

    Context Mode – An Open-Source MCP Server That Reduces AI Coding Context Usage

    Context Mode is an open-source MCP server that keeps raw tool output out of the context window via sandbox tools (claimed 315 KB to 5.4 KB, a 98% reduction), tracks session events in SQLite with FTS5/BM25 retrieval for continuity after compaction, and pushes agents to write analysis scripts instead of reading data into context. It ships install paths for 17 clients including Claude Code, Gemini CLI, VS Code and JetBrains Copilot, Copilot CLI, Cursor, OpenCode, KiloCode, OpenClaw/Pi Agent, and Codex CLI, with hook-based routing where supported.

    Will Agent Resource Registries ever have their moment, the way AI gateways did?

    ARD (Agentic Resource Discovery) is an open discovery protocol that lets an AI client ask what resources are available for a task and receive matching entries from a discovery service, operating entirely before invocation so the resource is then called through its own native mechanism. It is not an execution runtime or a central catalog: many discovery services are expected, each with its own trust, ranking and access policies, and it is being developed by a working group with participants from Microsoft, Google, Hugging Face and GoDaddy. ARD is licensed under Apache License 2.0 and welcomes community contributions.

    AI Warning for Steam – Increases Visibility of AI Generated Content Disclosures

    AI Warning for Steam is a browser extension and userscript that shows Steam store pages' AI Generated Content Disclosure as a modal popup on page load and blurs or hides games with such a disclosure on search pages. It is available as a Firefox or Chrome extension or as a userscript, all running the same code, and works in any up-to-date browser on desktop or mobile, though not all features are translated beyond English.

    Show HN: AIOps Cockpit – An open-source AI SRE with human-in-the-loop safety

    AIOps Cockpit is an open-source, self-hosted SRE control room that uses an AI agent (Claude 3.7) to diagnose incidents by reading logs and checking metrics, with a 3D spatial topology map and optional MediaPipe hand-gesture camera control. The AI never applies fixes directly: it generates a unified diff that a human must review and approve under a two-person rule, backed by append-only audit logs, prompt-injection defenses, and a strict tool allowlist with destructive actions disabled by default. It streams live host and Docker telemetry via Socket.IO, supports a lightweight remote agent for distributed servers, and requires Node.js 20+ and pnpm to run via `pnpm start`.

    Fruth – A semantic state inference engine for AI

    Fruth 0.1.9 is an experimental, single-maintainer project that separates model proposals from runtime authority, recording candidate work and using relevance and validated promotion to decide which obligations are owed. It combines a local browser interface and control plane with local model backends, interpretive inference routing, durable response frames, history and materialized artifacts, with a core loop of intent, possibility space, relevance, promoted contracts, runtime work, review and frozen state. The primary tested environment is a recent macOS release on Apple Silicon with Python 3.11 or newer, and Windows, Linux, Intel Mac, remote hosting and multi-user operation fall outside the 0.1.9 support promise.

    OpenAI's upcoming chat-and-work merger in ChatGPT signals the end of all-you-can-prompt pricing

    Starting in December, ChatGPT's Plus, Pro, and Business plans will share a single token budget across ChatGPT and Codex as OpenAI folds Work's agentic features into the main interface, per an updated OpenAI support page. Users can check remaining balance and reset times in Settings, and once the limit is hit they can wait for a reset, upgrade, or buy extra credits, while chats with Instant models won't count toward the budget. OpenAI recently doubled usage limits for higher-priced plans, and Anthropic has already combined Chat and "Cowork" in Claude.

    Meridian: A peer-to-peer browser game world built by an AI agent

    Meridian now runs as a playable demo from GitHub Pages on desktop or phone, with touch controls, a first-minute tour, and solo play by default since the temporary public lighthouse is switched off. The post details renderer polish (WebGL2 ray pass with CPU fallback, filmic tone mapping, sight- and focus-scaled rays), a minimap that paints where the view meets the ground, new agility and perception skills, and AI players driven only through the same keys a person presses. It also lists merged batches after recording: positional sound and hearing skills, trampled paths, 25 cm terrain cells, a leaner wire format (79% fewer bytes in one capture), a phone blank-screen fix, and a scaling bench run only to 4 clients.

    The Elephant-Goldfish Model: scaling design-driven AI development

    Google has open-sourced, under Apache 2.0, an Elephant-Goldfish Model plugin that pairs a context-rich "Elephant" design session (no code written) with stateless "Goldfish" sessions that validate specs through comprehension checks, antagonistic review, and a go/no-go readiness check. The plugin, originally built internally and used daily by thousands of Googlers, automates the EGM lifecycle in Antigravity, with other environments upcoming. The authors argue that "design is the new code" and that human judgment remains the key artifact in AI-assisted development.

    BU Ultrafast is live

    Browser Use has made BU Ultrafast, its fastest browser agent, available on every Browser Use Cloud plan in the US, including the free plan, after a waitlist period that ended Oct 30. The company reports a median task time of 22 seconds and $0.0064 per task for Ultrafast, versus 79 seconds and $0.0098 for its default agent on GPT-6 Luna, based on medians of completed runs from Oct 16-29, 2026. Users enable it by setting the model to bu-ultrafast, and bu-fast offers the same agent with more reasoning per step.

    Why it matters: It gives concrete speed and cost benchmarks for a newly released browser agent and explains how to switch to it via the API.

    mobile-agent: faster mobile app iteration for AI coding agents

    mobile-agent is an experimental, pre-release tool that drives Android devices and emulators, iOS Simulators and physical iPhones for AI agents, combining a daemon with a live mirror of each screen, a CLI following agent-browser's command grammar, and an MCP server for Claude Code, Claude Desktop, Codex or Cursor. On the repository's iOS Simulator fixtures it reports p50 times of 7.08 s for a login flow versus 35.9 s for Maestro and 13.0 s for agent-device, and 4.82 s for a 500-cell screen versus 30.0 s and 5.97 s respectively, though the list-scroll flow was not timed because every tool failed its golden check. It is built from source on macOS with drivers on private Apple and hidden Android interfaces, and the author states it is development tooling, never something to ship in an app.
