Description
Baseline Core is a free, open-source product methodology system delivered via a CLI that gives AI tools real product-management expertise. It includes 12 skills, 14 frameworks, and 34 reference files covering research, strategy, specs, design, sprint planning, and more, loaded into any AI tool that reads AGENTS.md. It is built by Baseline Studio, an agent-native studio founded by Trent Mitchell that publishes open-source tools and frameworks to give agents the context they need to do real work.

The system has three components that work together: universal skills that encode proven methodology, your own business context (positioning, voice, users, competitors, and product details), and frameworks for prioritization, research, messaging, and decision-making. When you run a skill, it loads both the methodology and your context, so outputs follow senior-level best practices and sound like your brand rather than generic AI text. Skills span strategic advisory, research synthesis, product communications, UX design, analytics, prototyping, project management, documentation, product marketing, and go-to-market planning.
Baseline Core is aimed at founders and small teams doing product work without a dedicated PM, such as researching a market, writing a PRD, planning a sprint, or handing off specs to engineering. It is tool-agnostic and works with Claude Code, Cursor, Windsurf, Codex, GitHub Copilot, and JetBrains AI, with ChatGPT and Gemini supported via file upload. It is MIT licensed with no accounts, rate limits, or upsell, and installs with a single npx command that scaffolds the skills, context, frameworks, and AGENTS.md into a project.
