Build Better Software With Kiro

Kiro is an agentic IDE backed by AWS that focuses on structured software development. It provides specs, agentic chat, steering, hooks, MCP integration and autonomous development workflows.

The main idea behind Kiro is to give AI agents more structure and constraints so developers can move from an idea to requirements, design, tasks and verified implementation.

Who Can Use Kiro?

• 💻 Software developers
• 🧑‍💻 Freelancers
• 🚀 Startup teams
• 🏢 Enterprise engineering teams
• 🎓 Programming students
• 🛠 DevOps engineers
• 🧪 QA engineers
• 🏗 Product engineering teams

From Prompt To Structured Plan

Many AI coding workflows start with a prompt and immediately generate code. Kiro instead emphasizes structure before implementation.

A feature can be expressed as requirements, then transformed into a technical design, then broken into implementation tasks that agents execute.

Core Flow

• 💡 Idea
• 📋 Requirements
• 🏗 Design
• ✅ Acceptance criteria
• 📝 Implementation tasks
• 🤖 Agent execution
• 🧪 Verification

Requirements → Design → Tasks

Kiro Feature Specs provide a structured approach to building new features. The workflow can begin with desired behavior and produce requirements, technical design and implementation tasks.

Requirements can include user stories and acceptance criteria, making the intended behavior easier to review before implementation begins.

Spec Artifacts

• 📄 requirements.md
• 🏗 design.md
• 📝 tasks.md
• 🎯 Acceptance criteria
• 📊 Architecture decisions
• 🔗 Implementation tracking

Fix Problems Systematically

Kiro also supports structured workflows for bug fixing. Instead of immediately changing code, an agent can investigate the issue, identify the likely root cause, design a fix and create implementation tasks.

Bug Workflow

• 🐞 Describe bug
• 🔍 Investigate
• 🧠 Identify root cause
• 🏗 Design solution
• 📝 Create tasks
• 🔧 Implement fix
• 🧪 Verify regression

One-Pass Planning

Quick Spec is designed for features where the developer already understands the problem and wants a faster planning workflow.

Kiro asks clarifying questions and then generates requirements, design and tasks in a single pass without approval gates between each phase.

Best For

• ⚡ Rapid prototyping
• 🚀 Well-understood features
• 🧪 Experimental projects
• 🏗 Straightforward implementations
• ⏱ Speed-focused workflows

Autonomous Development

Kiro agents can work through development tasks, modify files, execute commands, run tests and provide code diffs for developer review.

For larger tasks, developers can let agents execute multiple implementation steps while retaining control over permissions and changes.

Agent Tasks

• 🏗 Build features
• 🐞 Fix bugs
• ♻️ Refactor code
• 🧪 Run tests
• 📝 Update documentation
• 🔧 Modify files
• 🔀 Prepare Git changes
• 🚀 Automate workflows

Your Code, Your Rules

Steering files allow developers and teams to provide persistent project instructions for agents.

Teams can define coding standards, architecture conventions, preferred workflows, tools and project context so agent output follows established rules.

Steering Can Define

• 📐 Architecture standards
• 📝 Coding conventions
• 📂 Project structure
• 🧪 Testing practices
• 🔐 Security rules
• 📦 Preferred libraries
• ⚙️ Development workflows
• 👥 Team standards

Event-Driven Agents

Kiro Hooks can trigger automated agent workflows when events occur in a project.

For example, a team can configure an agent to update documentation or generate tests when a relevant file is saved.

Hook Examples

• 💾 File save
• 📝 Documentation generation
• 🧪 Test generation
• ⚡ Performance optimization
• 🔍 Code analysis
• 🔧 Automated maintenance

Model Context Protocol

Kiro supports MCP so agents can connect to external tools and data sources.

This allows development agents to operate beyond the files inside the IDE and interact with approved external services.

MCP Use Cases

• 🔌 External APIs
• 🗄 Databases
• 📚 Documentation
• 🐙 Git services
• 📋 Project management
• ⚙️ Development tools
• ☁️ Cloud services
• 🤖 Custom agent tools

Agentic CLI

Kiro CLI brings AI-assisted development into the terminal. Developers can use natural-language commands to build, test and deploy applications.

The CLI supports custom agents, MCP, hooks, steering, autocomplete and headless automation workflows.

CLI Features

• ⌨️ Interactive chat
• 🤖 Custom agents
• 🧩 MCP
• ⚙️ Smart hooks
• 🧠 Agent steering
• ✨ Autocomplete
• ⚙️ CI/CD automation
• 📋 Spec workflows

Web-Based Agentic Development

Kiro Web brings structured agentic development into the browser. Developers can select repositories, create specs, review requirements and design, and run implementation tasks.

Web Workflow

• 🌐 Open Kiro Web
• 📦 Select repository
• 📋 Create spec
• 🏗 Review design
• 📝 Review tasks
• 🤖 Run implementation
• 🔀 Open pull request

Autonomous Mode

Kiro provides autonomous development workflows where agents can work through larger tasks without requiring the developer to provide every individual instruction.

Developers remain in control through permissions, code diffs, review steps and the ability to interrupt the agent.

Good Autopilot Tasks

• 🏗 Feature implementation
• 🧪 Test creation
• 📝 Documentation
• ♻️ Refactoring
• 🔧 Repetitive maintenance
• 🐞 Bug fixes
• 📦 Dependency updates

Fine-Grained Agent Control

Kiro's newer CLI architecture includes capability-based permissions that can allow or deny categories of operations across tools.

This is useful when autonomous agents need access to development tools but organizations still want auditable controls over what agents can do.

Permission Areas

• 📂 File operations
• ⌨️ Shell commands
• 🌐 Network tools
• 🧩 MCP tools
• ⚙️ Agent capabilities
• 🔐 Security-sensitive actions

Model Choice

Kiro provides model choices that can include frontier models and open-weight models depending on the subscription and region.

Kiro also offers an Auto mode designed to select an appropriate mix of models and specialized techniques to balance quality, latency and cost.
