Kiro: Spec-Driven Development Workflow

Transform ideas into comprehensive specifications, design documents, and actionable implementation plans.

When to use

Use this skill when you want a Kiro-style spec pack under .kiro/specs/:

1. requirements with EARS acceptance criteria,
2. a design doc with architecture + correctness properties,
3. an executable tasks checklist.

Workflow

1. Requirements → Define what to build (EARS format) → Details
2. Design → How to build it (architecture + correctness properties) → Details
3. Tasks → Actionable implementation steps → Details
4. Execute → Implement one task at a time → Details

Storage: .kiro/specs/{feature-name}/ (kebab-case)

---

Core Rules

• Sequential phases — Never skip phases
• Explicit approval — Get user approval after each document
• One task at a time — During execution, focus on single task
• Correctness mandatory — Every design MUST include properties from EARS

Quick Reference

EARS Acceptance Criteria Format

WHEN [event] THEN THE [system] SHALL [response]
IF [condition] THEN THE [system] SHALL [response]
WHILE [state] THE [system] SHALL [response]

Correctness Property Format

### Property N: [Name]

_For any_ [inputs], [precondition], [system] SHALL [behavior].

**Validates: Requirement X.Y**

Phase Outputs

Phase	Output File	Key Content
Requirements	requirements.md	User stories + EARS ACs
Design	design.md	Architecture + Interfaces + Properties
Tasks	tasks.md	Checkbox task list

Detection Logic

Determine current state by checking:

# Check for .kiro directory
if [ -d ".kiro/specs" ]; then
  # List features
  ls .kiro/specs/

  # For specific feature, check phase
  FEATURE="$1"
  if [ -f ".kiro/specs/$FEATURE/requirements.md" ]; then
    echo "Requirements exists"
  fi
  if [ -f ".kiro/specs/$FEATURE/design.md" ]; then
    echo "Design exists"
  fi
  if [ -f ".kiro/specs/$FEATURE/tasks.md" ]; then
    echo "Tasks exists - ready for execution"
  fi
fi

Summary

Kiro provides a structured, iterative approach to feature development:

• Start with requirements (what to build)
• Progress to design (how to build it)
• Create tasks (implementation steps)
• Execute tasks one at a time

Each phase requires explicit user approval before proceeding, ensuring alignment and quality throughout the development process.
