Two Kiro IDE Development Modes: Flexibility Meets Structure

Kiro IDE offers two distinct approaches to AI-assisted development, catering to different project needs and developer preferences. Understanding these Kiro IDE modes is essential for maximizing your Kiro IDE productivity:

1. Vibe Chat First, Then Build

This traditional mode mirrors other AI IDEs, allowing developers to:

• Provide direct prompts for immediate code generation
• Make real-time changes to the codebase
• Iterate quickly without formal planning
• Perfect for rapid prototyping and experimental development

2. Spec Plan First, Then Build

Kiro's revolutionary approach that emphasizes planning before implementation:

• Systematic requirement gathering and documentation
• Comprehensive design phase with architectural planning
• Structured task breakdown and implementation roadmap
• Ideal for complex projects requiring deep thinking and structured development

The Spec-Driven Development Workflow

Phase 1: Specification Creation

The journey begins with transforming your initial prompt into a comprehensive specification document:

Requirements Generation: Kiro analyzes your input and creates detailed requirements.md files containing:

• User stories with clear acceptance criteria
• Functional and non-functional requirements
• Scope definition and project boundaries
• Success metrics and validation criteria

Assumption Clarification: The AI explicitly states assumptions, allowing you to review and modify before proceeding to implementation.

Iterative Refinement: You can edit and refine requirements until they perfectly capture your vision.

Phase 2: Design Documentation

Once requirements are finalized, Kiro performs deep codebase analysis to create comprehensive design documentation:

Architecture Overview: Complete system architecture with component relationships Technology Stack Analysis: Detailed breakdown of current and recommended technologies Data Flow Diagrams: Visual representation of information flow through the system TypeScript Interfaces: Precise type definitions for all data structures Database Schema: Complete data model with relationships and constraints API Endpoint Specifications: Detailed REST API documentation Visual Documentation: Mermaid diagrams and flowcharts for complex processes

This phase ensures complete understanding before any code is written.

Phase 3: Implementation Planning

The final planning phase creates a detailed execution roadmap:

Task Breakdown: Comprehensive list of implementation tasks and subtasks Dependency Mapping: Clear understanding of task relationships and prerequisites Testing Strategy: Built-in test cases and error handling considerations Quality Assurance: Code review checkpoints and validation steps

Phase 4: Execution

With planning complete, implementation becomes systematic and efficient:

Individual Task Execution: Start tasks individually for granular control Queue Management: Batch multiple tasks for automated sequential execution Progress Tracking: Real-time monitoring of implementation progress Quality Control: Automated testing and validation at each step

Spec Synchronization: Keeping Documentation Current

One of Kiro's most powerful features is bidirectional synchronization between specifications and code:

Code-to-Spec Updates: After manual code changes, request Kiro to update specifications Spec-to-Code Optimization: Modify specifications and have Kiro adjust implementation plans Living Documentation: Specifications remain current throughout the development lifecycle Team Alignment: Ensures all team members work from the same understanding

Agent Hooks: Event-Driven Automation

Agent Hooks represent Kiro's most revolutionary feature - intelligent automation that responds to development events:

How Hooks Work

Event Monitoring: Hooks listen for specific file system events:

• File creation
• File saves
• File deletion
• Custom triggers

Automated Response: When events occur, predefined prompts are sent to AI agents for background execution

Seamless Integration: Automation happens transparently without interrupting your workflow

Practical Hook Applications

Documentation Updates: Automatically update README files when API endpoints change Test Generation: Create or update unit tests when React components are saved Storybook Maintenance: Update component stories when UI components are modified Code Quality: Run linting and formatting checks on file saves Dependency Management: Update package documentation when dependencies change

Creating Custom Hooks

Hook creation uses natural language descriptions:

1. Access Hook Management: Click the ghost icon in Kiro's sidebar
2. Describe Automation: Use natural language to explain desired behavior
3. Configure Triggers: Select appropriate file system events
4. Test and Refine: Validate hook behavior with real scenarios

Team Collaboration with Hooks

Version Control Integration: Hooks are saved as files in your repository Team Sharing: Git commits include hook configurations for team consistency Standardization: Ensure uniform practices across all team members Reduced Mental Load: Automate routine tasks that developers often forget

Additional Features and Capabilities

Agent Steering
