Kiro is an agentic engineering platform and CLI coding agent built and operated by AWS. It extends beyond standard code-completion assistants by implementing a spec-driven development workflow, translating user prompts into structured requirements, architectural designs, and sequenced execution tasks. In daily operations, developers interact with Kiro via its standalone CLI, the Kiro Crew workspace, or dedicated IDE integration. The agent orchestrates subagents to implement tasks locally or through managed cloud sessions. Kiro supports multiple foundational models, including Anthropic Claude (Opus, Sonnet, Haiku), DeepSeek, MiniMax, and an intelligent Auto mode that selects the model dynamically based on task complexity, latency, and cost. Kiro differentiates itself through its emphasis on automated reasoning, property-based testing (PBT), and open integration standards. Instead of solely relying on standard unit tests, Kiro tests requirements for contradictions and runs property tests to validate edge cases across all input spaces. It conforms to open ecosystem standards including the Agent Client Protocol (ACP), Model Context Protocol (MCP), AGENTS.md, and Skills.md, and offers headless CLI execution for CI/CD automation. Commercial access is managed through a credit-based pricing model with multipliers scaled to the chosen model tier, supported by AWS enterprise-grade security features such as IAM/SSO authentication, IP indemnity, and centralized governance controls.
