Kiro Documentation

Kiro is an agentic coding service that works alongside you to turn prompts into detailed specs, then into working code, docs, and tests. Kiro’s agents help you solve challenging problems and automate tasks like generating documentation and unit tests.

Kiro is built on Amazon Bedrock, a managed service for building generative AI applications that uses foundation models (FMs) from Amazon and third party AI companies. Kiro uses multiple FMs to complete its tasks. AWS implements automated abuse detection.

You can chat with Kiro about your code through natural language conversations. You can ask questions about your codebase, request explanations for complex logic, generate new features, debug tricky issues, and automate repetitive tasks.

With Kiro you can go from a natural language prompt to application feature. Access interactive step-by-step instructions, design documents, data flow diagrams, code, tests, and best practices. Kiro is designed to understand your workspace structure and breaks down your prompt into logical implementation steps, which can include generating code, tests, API integrations, and more. You can collaborate with Kiro to review and iterate on the implementation, and, when ready, ask Kiro to help implement each step.

With Kiro, you can use structured artifacts called specifications, or specs, that formalize the development process for complex features in your application. Spec-based coding provides a systematic approach to transform high-level ideas into detailed implementation plans with clear tracking and accountability.

Kiro allows you to use agent hooks, which are automated triggers that execute predefined agent actions when specific events occur. Rather than manually asking for routine tasks to be performed, hooks set up automated responses to events such as saving files, creating new files, and deleting files.

Instead of explaining your conventions in every chat, you can create and use steering files in Kiro to provide persistent knowledge about your project through markdown files. Steering files help Kiro consistently follow your established patterns, libraries, and standards.

Kiro may use certain content from Kiro Free Tier and Kiro individual subscribers for service improvement. For enterprise users, Kiro gives administrators the option to create customer managed keys to encrypt their data.
