AWS Kiro CLI 2.0 released
AWS announced Kiro CLI 2.0 with headless CI/CD support, Windows compatibility and UX improvements like task lists to aid terminal‑centric automation and troubleshooting. The update is aimed at developers and operators who script workflows and integrate CLI actions into pipelines. The changelog emphasises automation and cross‑platform parity for CLI‑first workflows.

Amazon Web Services released Kiro CLI 2.0 on April 13, adding Windows support and a headless mode for automation pipelines. (kiro.dev) Kiro CLI is Amazon Web Services’ terminal tool for running coding agents from the command line instead of a browser or graphical editor. Amazon Web Services said the 2.0 release lets users pass prompts with `--no-interactive` and authenticate with a `KIRO_API_KEY` environment variable for continuous integration and continuous deployment jobs. (aws.amazon.com) (kiro.dev) The same April 13 changelog said Kiro CLI now runs natively on Windows 11, bringing feature parity with macOS and Linux for terminal user interface sessions, headless runs, custom agents, and Model Context Protocol servers. Amazon Web Services also made the terminal user interface the default chat experience after previously shipping it behind an experimental flag. (kiro.dev 1) (kiro.dev 2) That change targets a specific workflow: developers and operators who already script builds, tests, and deployments from a shell. Amazon Web Services had been pitching Kiro CLI for DevOps work since at least December 10, 2025, when an AWS Public Sector Blog post showed it generating Terraform, managing Amazon Elastic Kubernetes Service setup, and working through terminal-based automation tasks. (aws.amazon.com) Kiro’s pitch is that a natural-language prompt becomes a structured spec, then a design, then a sequenced task list that agents can execute. On Kiro’s product site, the company says those tasks can be ordered by dependencies, which matches the 2.0 release’s new support for subagent task dependencies in the command-line tool. (kiro.dev 1) (kiro.dev 2) The interface changes are aimed at people who stay in a terminal for long stretches. The new default view adds syntax-highlighted markdown, keyboard shortcuts, a real-time “crew monitor” for subagent activity, transcript review in a pager, and commands such as `/spawn` for parallel agent sessions. (kiro.dev) The release also sharpens the product split from Amazon Q Developer CLI. The open-source Amazon Q Developer CLI repository on GitHub now says it is no longer being actively maintained except for critical security fixes, and directs users to Kiro CLI as the current product. (github.com) That leaves Kiro CLI 2.0 as Amazon Web Services’ current command-line path for teams that want agentic coding inside scripts, shells, and build systems instead of a browser tab.
