Ask user:
To create a comprehensive modernization plan, I need to understand:
1. **Codebase Location:**
- Where is the legacy system? (e.g., /codeRepos/MyApp)
2. **Modernization Goals:**
- [ ] Cloud migration (Azure, AWS, or GCP?)
- [ ] Microservices transformation
- [ ] Both (full modernization)
3. **Current State:**
- What type of application? (Web, API, monolith, distributed services)
- Approximate number of services/projects (if known)
- Technology stack (if known)
4. **Requirements (if applicable):**
- Availability targets (99.9%, 99.95%, 99.99%)?
- RPO/RTO requirements for DR?
- Compliance needs (HIPAA, SOC2, PCI-DSS, GDPR)?
- Budget constraints?
- Timeline expectations?
I'll analyze the codebase to discover specifics, but this context helps prioritize the analysis.

š” **Tip:** Your analyzed codebase remains clean - no artifacts written to source directories.
Problem Solved:
ā Before: Artifacts scattered across directories

/codebase/ ā clean, no artifacts
Handles enterprise complexity: - Multi-solution codebases (Web + API + Services) - 30-50+ individual services - Cross-service dependency mapping - Database-per-service planning - Performance and security flags at service level
Complete migration strategy: - Azure/AWS/GCP architecture design - HA/DR strategies with specific RPO/RTO - Good/better/best migration approaches - TCO calculations and ROI analysis - Phased implementation roadmaps
Domain-driven decomposition: - Bounded context identification - Service boundary recommendations - Data decomposition strategies - Strangler fig migration patterns - Event-driven architecture design
ā Run from workspace directory - Not from codebase
# Good: Run from your workspace
cd /workspace/architecture-reviews
# Analyze external codebase
"Analyze /codeRepos/LegacyApp for cloud migration"
# Outputs go to /workspace/architecture-reviews/.orchestr8/session_xxx/
ā Specify requirements upfront - Save analysis time
Include in request:
- Cloud preference (Azure/AWS/GCP)
- Availability requirements (99.95%)
- Compliance needs (HIPAA, SOC2)
- Budget constraints
ā Review session metadata - Understand analysis scope
cat .orchestr8/latest/metadata.json
ā Use structured outputs - YAML for automation
# service-map.yaml - Machine readable
# Can be consumed by migration tools
ā Sessions isolate concurrent analyses
Run multiple analyses from same directory:
.orchestr8/
