From OpenAPI/Swagger specifications to test suite in seconds with Kiro

Here's a 3-sentence summary of the blog post: Kiro automates the process of generating a complete test suite from an OpenAPI/Swagger specification, eliminating the need for manual test development and reducing the effort required to maintain test coverage as the API evolves. Unlike traditional tools like OpenAPI Generator, Kiro reasons over the specification to generate executable tests with assertions, a mock server, and schema validation, providing a more reliable signal of actual API conformance. With Kiro, teams can regenerate their tests automatically when the specification changes, reducing the risk of tests drifting away from the actual API behavior.

Introducing Agent Focus

Kiro introduces Agent Focus, an experimental IDE view that shifts the focus from code to agent interactions. This new view allows developers to launch and manage multiple agent sessions in parallel, chat with agents, and visualize progress through three intuitive panels. With Agent Focus, developers can adopt a chat-first approach to building, while still having access to the existing IDE experience.

Test Driven Development (TDD) with Kiro: this is how it should feel

Engineers at the author's previous organization implemented unit testing to improve code quality, but struggled to consistently apply TDD due to its perceived time-consuming nature and context switching requirements. Kiro, an agentic development tool, supports spec-driven development and hooks to enable enforcement of specific practices like TDD. The author created a Kiro hook to automate the discipline of TDD, enforcing the red-green-refactor cycle by prompting to write failing tests before production code and writing minimal code to pass, then refactoring as needed. This hook runs each time Kiro attempts to save a file, ensuring the TDD process is followed, making TDD feel like a beneficial practice rather than a burden.

Introducing Kiro Web

Kiro Web is a new tool that allows users to start tasks without an IDE, providing a web-based interface to tell Kiro what needs to be built and having it write code and open pull requests automatically. The tool uses steering files, which define team coding conventions, to learn from user feedback and improve its performance. Currently in preview, Kiro Web can work across multiple repositories in a single session, and its capabilities will expand to Kiro IDE and Kiro CLI in the coming weeks.

Specs just got faster (and smarter)

Here's a 3-sentence summary of the blog post: Kiro has introduced improvements to its spec flow, allowing users to run tasks in parallel and generating a dependency graph to minimize wait times. The quick plan mode also streamlines the process by auto-generating requirements, design, and tasks in one pass, while analyzing the user's prompt for clarifications and ambiguities. These updates aim to provide "speed where it helps and depth where it matters", catching subtle issues in requirements analysis and reducing implementation time by up to 75%.

Requirements analysis: catching requirement bugs before they become code

Here's a 3-sentence summary of the engineering blog post: To prevent bugs and issues, engineers need to catch requirements bugs before they become code, which can be achieved through a structured workflow and requirements analysis. Requirements analysis detects four types of bugs: wrong level of detail, ambiguity, inconsistency, and incompleteness, which can be challenging to spot using traditional methods. A new optional step in the workflow, requirements analysis uses neuro-symbolic techniques and formal logic to verify requirements and flag potential issues, automating the process of checking generic quality properties such as testability, solution-freeness, unambiguity, consistency, and completeness.

Root cause in 33 seconds: How Kiro CLI saved 4 years of build time

Kiro CLI's root cause analysis toolchain identified a performance bottleneck in a legacy codebase, reducing build times from over 30 minutes to under 1 minute. The tool analyzed profiling data and code structure to pinpoint a config file parser consuming 80% of CPU time due to repeated re-initialization. Using a combination of code intelligence, file system, and subagent tools, Kiro implemented a fix by introducing a shared cache, reducing 4 years of monthly compute time and accelerating future investigations by leveraging AI-assisted development capabilities.

Run Kiro CLI programmatically: introducing headless mode

To run Kiro CLI programmatically, a headless mode was introduced, allowing for automated workflows without a browser. This is achieved by generating an API key and setting it as an environment variable, KIRO_API_KEY, which skips the browser-based login flow. A concrete example demonstrates an automated code reviewer that runs on every push via GitHub Actions, utilizing a custom Kiro agent and a GitHub Actions workflow to review code for security issues and best practices.
