News related to:Spider Networks Inc · 3 min read
Spider Networks Inc. has launched KUKURI - Agent Rules Hub, a new platform designed to help users tailor artificial intelligence (AI) agents and chatbots to their specific needs. The service, available as of November 10, 2026, offers a comprehensive library of instructions that can be used to program AI agents and chatbots, ensuring they operate in a manner that aligns with user preferences.
KUKURI - Agent Rules Hub is a web-based platform accessible via any web browser. It provides a wide range of instructions for various applications, from software development to customer support, website design, and more. These instructions can be used as-is or edited and combined to fit specific work requirements. The library covers a broad spectrum of tasks, including loop engineering, presentation slide deck creation, and customer complaint handling.
The service is particularly useful for individuals and businesses looking to leverage AI agents such as Claude Code, Codex, Muse, Antigravity, ChatGPT, Gemini, and Muse. Users can download instructions as AGENTS.md, CLAUDE.md, or GEMINI.md files for Claude Code, Codex, and Antigravity. For ChatGPT, Gemini, Claude, and Muse, users can copy and paste the text into the AI's settings.
KUKURI - Agent Rules Hub is available in eight languages: Japanese, English, Chinese, Spanish, German, Portuguese, French, and Korean. The service offers a free plan, with paid plans starting at $7 per month. The company aims to expand the range and content of the instructions based on user feedback, ensuring that more people can achieve their desired outcomes with AI.
In addition to the current form, where users work on the site themselves, Spider Networks is considering providing an MCP server (a standard way for AI agents to use outside services) so that users' own AI agents can connect to KUKURI - Agent Rules Hub directly to search, retrieve, and edit instructions. The company is also considering a plan for companies that want to use the service on a large scale.
Background information reveals that AI agents such as Claude Code and Codex are used in software development. In October 2026, Meta began offering Muse, which it calls a personal AI agent, in Japan, giving people outside engineering more opportunities to use AI agents. AI agents such as Claude Code and Codex read instruction files such as AGENTS.md and CLAUDE.md and carry out their work according to them. Chat AIs can also be set up in advance so that they answer and work the way the user intends. The quality of these instructions has a large effect on how well the AI performs, yet it is often unclear what to write.
Common issues include not knowing what to put in an instruction file and having to type the same instructions into a chat AI every time. KUKURI - Agent Rules Hub was developed to address these issues, so that even people who have just started using AI can quickly prepare instructions that fit their work. The library of instructions covers programming, design, writing, sales, email, customer support, research, data analysis, education, operations management, and more. For example, users can choose instructions for "loop engineering," which keep an AI agent working on a long task by itself and stop it within set limits, or instructions that pick a template matching the desired mood and build a presentation slide deck, practical instructions that AI agent users can apply in their daily work.
Any instruction can be edited on the site. Users can also take just the parts they need from other instructions and connect them, combining tone, the way the AI answers, and the way it works into instructions that fit their own work. The service also supports both AI agents and chat AIs, with finished instructions downloadable as AGENTS.md, CLAUDE.md, or GEMINI.md files for Claude Code, Codex, and Antigravity. For ChatGPT, Gemini, Claude, and Muse, users copy the text and paste it into the AI's settings (for Muse, the "Soul" field). The guide on the site explains the procedure for each AI.
Spider Networks Inc., based in Urayasu-shi, Chiba, Japan, is a company that specializes in AI services and web system development. The launch of KUKURI - Agent Rules Hub is part of the company's ongoing efforts to make AI more accessible and user-friendly.
