Spec Kit

Spec Kit is GitHub's official toolkit for Spec-Driven Development — a workflow where you write a clear specification first and let AI coding agents implement against it. It turns vague vibe-coding into a repeatable, reviewable process.

The idea

Rather than prompting your agent one feature at a time, you author a structured spec (a PRD-like artifact), and the agent plans, breaks down, and builds from it. That keeps large agent-built projects coherent instead of drifting.

• Spec-first workflow that scales beyond one-off prompts
• Works with Copilot and other coding agents
• Bridges product intent and generated code
