  1. Show HN: I Turned DOOM into a Transformer

    Doomformer compiles integer neural networks into ZDoom maps that run in ViZDoom. Voodoo dolls do the arithmetic, and sector light levels and plane heights hold the values. Python reads every value back and compares it with a NumPy integer reference at tolerance 0. It runs MNIST (97.16 % on all 10,000 digits, every pass exact), small transformers, a learning perceptron and a SUBLEQ machine. It is about 23,000 times slower than NumPy on a small MLP.

  4. santosomar/AI-agents-for-cybersecurity

    Companion repository for Omar Santos's Pearson and O'Reilly trainings and books. It has eight parts of runnable Python labs: chat models, embeddings, prompt templates, LCEL prompt chaining, Chroma-based RAG, ReAct/LangGraph/CrewAI/DeepAgents agents, and FastMCP servers (nmap, CISA KEV, Shodan). It also includes guides to six agentic frameworks (OpenClaw, Hermes, Agent Zero, OpenHands, Paperclip, Buzz), a tokenomics module on agent cost (context compounding, prompt caching, model routing, token budget guards, batch API, cost per accepted outcome), and a vendor-neutral design spec for a human-gated multi-agent assessment harness. It is a current, practical curriculum for building and operating agents. Some examples act on real systems and should only be run in an authorized lab.

  8. Show HN: Made an open-source Lego AI generator

    ldraw-nova is an open-source agentic pipeline where an LLM agent (tested with models like Claude Opus 5.5 and GPT-6 Astra) takes a build prompt, reads LDraw-building instructions, and produces a plan.json describing a model's geometry. From that plan it writes a Python generator script that, when executed, outputs an LDraw (.mpd) 3D CAD source file, viewable in 3D/VR (Meta Quest 3) or exportable to Blender-editable glTF. The agent uses jev-rerank, a semantic search tool with reranking backed by TypeSafe's Jev System One model, to find suitable LEGO parts and example models, falling back to full-text search without an API key; it also uses headless rendering and collision/gap detection to self-inspect and iterate on designs.

  10. https://github.com/Panniantong/Agent-Reach

    Agent-Reach is a CLI and agent-"skill" layer that equips coding agents (Claude Code, Cursor, OpenClaw) with ready-made web-reading tool use: fetching arbitrary pages via Jina Reader, YouTube transcripts via yt-dlp, GitHub repos via gh CLI, Bilibili search, RSS via feedparser, and semantic web search via Exa through mcporter, with login-gated platforms (Twitter/X, Reddit, Xiaohongshu, Facebook, Instagram) added on request via cookies or OpenCLI browser sessions. Each platform module probes an ordered list of candidate backends and falls back automatically when one breaks (e.g. yt-dlp being blocked by Bilibili's anti-scraping), and an `agent-reach doctor` command reports which backend each channel is currently using. It positions itself as a "capability layer" that selects, installs and health-checks the right upstream tool for an agent rather than wrapping the reads itself.

  12. rehan-remade/universal-modder

    universal-modder is a set of Agent Skills, a CLI (um) and a shared knowledge base (field notes in knowledge/) that let AI coding agents such as Claude Code, Codex, Gemini CLI, Cursor, GitHub Copilot and OpenCode find a PC game's engine, reverse-engineer its code, build a working mod, generate art/3D/sound assets via the fal MCP server (or a local ComfyUI server), test the mod in the running game, and write a field note for the next agent. It ships worked examples — a weapon/boss pack for Terraria via tModLoader, a new civilization for Age of Empires II DE, and a real-time Minecraft-inside-GTA-V passthrough mod — each documented with a field note of exact versions, routes and gotchas, and agents can open pull requests to grow the shared knowledge base.

  18. CVE-2026-42533 nginx heap buffer overflow PoC (pre-auth RCE via two-pass capture clobbering)

    A public PoC repo for CVE-2026-42533, a pre-auth heap buffer overflow in nginx's two-pass string evaluation engine that occurs when a regex-based map directive using numbered captures ($1, $2) clobbers the shared r->captures state used by a regex location, causing a LEN/VALUE size mismatch. The overflow can corrupt an adjacent ngx_pool_cleanup_t structure to hijack a function pointer for RCE, or under-write to leak heap/libc pointers defeating ASLR; the repo ships exploit.py/leak.py/overflow.py plus a Docker test environment demonstrated at 10/10 reliability on Ubuntu 24.04 against nginx 0.9.6-1.30.3/1.31.2. It also documents the exact vulnerable config pattern, a config scanner link, and the fix (named captures or upgrade to nginx 1.30.4+/1.31.3+).

  19. Numbat

    Numbat is a Go-based, single-binary endpoint agent from Perplexity AI that gives visibility into AI coding-agent activity (Claude Code, Codex, OpenClaw, and other CLI/IDE/gateway agents) by capturing events through local hooks, OTLP/HTTP logs, and on-disk session artifacts. It normalizes activity into one event model, evaluates it with a local CEL rule engine (including multi-step sequence rules like secret-read-then-egress), and can optionally block matched actions via synchronous pre-action hooks (deny/monitor decisions), with case bundles and SHA-256 manifests for forensic reconstruction. Example built-in rules detect cloud-metadata SSRF requests (169.254.169.254) and credential-exfiltration chains, mapped to MITRE ATT&CK technique tags.

  20. kajisho5/ffmpeg-skill

    ffmpeg-skill is an Agent Skill (SKILL.md plus 42 stdlib-only Python tools) that lets Claude Code, Cursor, Codex and other agents edit video and audio with local ffmpeg/ffprobe. It enforces a probe → edit losslessly → check → verify workflow, and every tool takes --dry-run, --json and --plan. A machine-readable contract, whose input schemas are derived at run time from each script's argparse parser (the author's "SPEC" pattern), drives an MCP server that lists a core 12 tools by default. The repo also ships per-platform render templates, a doctor capability check, a test suite and evals. It is useful as a worked example of a deterministic, verifiable skill/tool layer in which the agent supplies judgement and the tools do the work.
