About agentii-kit
agentii-kit is an open-source ecosystem built on Spec-Driven Development—a methodology inspired by spec-kitthat makes specifications executable, not just documentation.
Our mission is to empower developers, product managers, designers, and teams with battle-tested kits. Whether you're building with Claude Code, Cursor, or Windsurf—we provide the structure you need.
We serve teams across development, product, marketing, legal, finance, and operations—because great AI agents require perspectives from all disciplines.

What People Say
PMF Kit's /pmfkit.pmf workflow forced us to define personas and jobs-to-be-done before writing a single line of code. We validated our hypothesis in 3 weeks instead of 3 months—spec-driven development is a game changer for early-stage founders.
