# Cloud Readiness Assessor Skill

Assesses application readiness for cloud migration, classifying applications using the 6Rs methodology and verifying cloud-native compliance.

## Purpose

Enable cloud migration planning for:
- 6 Rs classification
- Cloud-native pattern compliance
- Stateless verification
- External dependency mapping
- Cost estimation

## Capabilities

### 1. 6 Rs Classification
- Rehost (Lift and Shift)
- Replatform (Lift and Reshape)
- Repurchase (Replace/SaaS)
- Refactor (Re-architect)
- Retire (Decommission)
- Retain (Keep on-premises)

### 2. Cloud-Native Pattern Compliance
- Check twelve-factor compliance
- Verify statelessness
- Assess horizontal scalability
- Evaluate config externalization

### 3. Stateless Verification
- Identify session storage
- Find local file usage
- Detect in-memory caches
- Map persistent connections

### 4. External Dependency Mapping
- Map database connections
- Identify external APIs
- Find message queue usage
- Document service dependencies

### 5. Cost Estimation
- Estimate cloud compute costs
- Project storage costs
- Calculate data transfer
- Model reserved vs on-demand

### 6. Risk Assessment
- Identify migration blockers
- Assess complexity
- Evaluate downtime risk
- Document compliance concerns
