BigPlan is an AI-powered product research skill that follows the open Agent Skills standard, which means it works across multiple AI agent frameworks that support this convention. It is compatible with DeepSeek Harness, OpenClaw, and Claude Code, among others, and provides structured market, technical, and supply chain analysis for product ideas. There are two common installation methods for most agents: you can clone the repository to your user-level shared agent directory at ~/.agents, or copy it to the .agents folder in your current project. OpenClaw users can also install it via the command npx clawhub install bigplan, which pulls the skill directly from ClawHub.

BigPlan is built for product managers, startup founders, and market researchers who need to kick off new product planning or research work. Once installed, it will appear in your agent’s skill list, and you can invoke it by typing the name BigPlan and describing the product direction you want to research. It will automatically walk through the steps of competitive analysis, market sizing, technical feasibility assessment, and supply chain mapping to generate three different tiers of product specification proposals for your reference. This helps cut down the time you spend on initial research and gives you concrete starting points for further work.

BigPlan has no external script dependencies, because it works entirely via prompt engineering, so you do not need to install any extra packages or run any build steps to use it. The official documentation recommends pairing BigPlan with a web search tool, because the skill does not include any built-in data gathering capabilities. It is released under the open source MIT license, which means you can use, modify, and redistribute it freely for both personal and commercial purposes without any cost. Once your agent loads BigPlan after installation, it will be available for use any time you need to run product research.
