A network load-balancer implementation for Kubernetes using standard routing protocols

Open-source IoT Gateway - integrates devices connected to legacy and third-party systems with ThingsBoard IoT Platform using Modbus, CAN bus, BACnet, BLE, OPC-UA, MQTT, ODBC and REST protocols.

One brain, many harnesses. Portable .agent/ folder (memory + skills + protocols) that plugs into Claude Code, Cursor, Windsurf, OpenCode, OpenClaw, Hermes, or DIY Python — and keeps its knowledge when you switch.

This is an IoT device communication protocol implementation client, which will include common industrial communication protocols such as mainstream PLC communication reading, ModBus protocol, and Bacnet protocol. This component is open source and free for life, using the most relaxed MIT open source agreement, you can modify and commercial use at will (commercial use please evaluate and test). 这是一个物联网设备通讯协议实现客户端，将会包括主流PLC通信读取、ModBus协议、Bacnet协议等常用工业通讯协议。本组件终身开源免费，采用最宽松的MIT开源协议，您可以随意修改和商业使用（商业使用请做好评估和测试）。

An industrial IoTGateway with B/S architecture that enables bidirectional communication between industrial devices (southbound connections) and IoT platforms (northbound connections). It supports numerous industrial protocols, and can connect to various IoT cloud platforms.

Answer Engine Optimization (AEO) skill — optimize content to be cited by AI language models (ChatGPT, Perplexity, Claude, Gemini, Mistral) as authoritative sources. Distinct from SEO — AEO optimizes for citation in LLM-generated responses, not search rankings. Use when planning content for AI-first search audiences, auditing existing content for E-E-A-T signals, tracking which pages get cited by which LLMs, or building a citation-friendly content strategy. Triggers — 'AEO audit', 'optimize for ChatGPT', 'get cited by Perplexity', 'LLM citation strategy', 'answer engine optimization', 'content for AI search', 'E-E-A-T audit'. Output is a markdown audit report (default) or JSON for pipeline integration. Stdlib-only Python tools.
