Kiro IDE

Kiro is an agentic AI IDE and CLI designed to bridge the gap between rapid prototyping and production-ready engineering through spec-driven development.

Built by AWS on Code OSS, Kiro moves beyond standard AI code completion to provide a comprehensive agentic development environment. It employs a spec-driven methodology that converts natural language prompts into structured requirements (EARS notation), technical designs, and executable tasks. Key features include Agent Hooks for background task automation, Steering Rules to enforce project-wide AI behavior, and native support for the Model Context Protocol (MCP) to integrate specialized data sources. By automating documentation, unit test generation, and complex refactoring across entire codebases, Kiro provides the rigor necessary for teams to scale agentic workflows without sacrificing code quality or architectural integrity.
