We've been busy making LeanSpec easier to adopt and more powerful to use. Whether you're exploring spec-driven development for the first time or scaling to enterprise workflows, these updates accelerate your journey from intent to working code.

What's new: Example projects for instant hands-on learning, JSON output for automation, simplified templates, and major improvements to our MCP server integration.

Your spec fits in the context window. So why does your AI agent make mistakes, ignore instructions, and produce worse code?

You paste a detailed 2,000-line architecture document into Cursor. The context window can handle it—200K tokens, plenty of room. But something's off. The AI suggests an approach you explicitly ruled out on page 3. It asks questions you already answered. The code it generates contradicts the design decisions you documented.

The problem isn't context size. It's context quality.

We're excited to introduce LeanSpec - a lightweight, flexible Spec-Driven Development (SDD) methodology designed for modern AI-powered development.
