Spec-driven agentic AI IDE from AWS, built on Code OSS (the VS Code foundation), that transforms ad-hoc prompting into a structured workflow by auto-generating requirements documents, design specs, and implementation plans before writing code. Kiro keeps AI-written code tied to explicit acceptance criteria defined up front.
