mainframe-architect

What problem does it solve?

Mainframe applications rely on legacy paradigms (VSAM, IMS, CICS, JCL) that do not map directly to cloud platforms, creating high friction and risk when planning migration. This Skill consolidates inventory and profiling outputs to produce a concrete, actionable target architecture that downstream translation, data migration, and cutover phases can implement.

Core Features & Use Cases

• Microservice Boundary Definition: Translate call-graph communities and workload profiles into candidate microservices and migration priorities.
• Database Migration Mapping: Map VSAM types and IMS hierarchies to relational schemas and object stores with recommended tools and table naming conventions.
• CICS → REST & Batch → Event Design: Generate OpenAPI-compatible endpoint definitions and cloud-native workflow DAGs (including Airflow DAG skeletons for GCP).
• Architectural Governance: Produce ADRs, an architecture overview, and an output checklist to validate blockers before marking Phase 03 complete.

Quick Start

Run phase 03 by asking the assistant to analyze Phase 01 and Phase 02 outputs and generate microservice boundaries, database migration maps, REST API designs, batch workflow definitions, and ADRs into docs/03_architecture/.
