mainframe-planning SKILL.md skillA
mainframe-planning from openhands/extensions is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add openhands/extensions/mainframe-planning@git:20260306.cebd78bPins git:20260306.cebd78b in mdr.lock. Pin the fingerprint instead.

Create a transformation guide for replacing mainframe-specific COBOL constructs with standard COBOL equivalents. Use when preparing COBOL code for local execution or migration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Create a comprehensive transformation guide that maps each mainframe dependency to its standard COBOL replacement. This guide is a prerequisite for the actual transformation — DO NOT modify any code, only create the guide. ## Output Format Document each mainframe-specific construct with: 1. **Pattern**: The mainframe construct (e.g., `EXEC CICS READ FILE(...)`) 2. **Replacement**: The standard COBOL equivalent 3. **Error Handling**: How to replicate the mainframe's error behavior - Map CICS RESP/RESP2 codes to FILE STATUS equivalents - Specify which FILE STATUS values to check (e.g., 00=success, 23=not found, 35=file not exists) 4. **Resource Cleanup**: Any cleanup the replacement requires (CICS auto-manages resources; file I/O does not) 5. **Edge Cases**: Behavior differences between mainframe and standard COBOL ## Constructs to Address ### Data Operations (CICS/IMS/VSAM) - READ, WRITE, REWRITE, DELETE operations - STARTBR, READNEXT, READPREV (browse operations) - CICS error handling: HANDLE CONDITION, RESP/RESP2 options - VSAM → sequential or indexed file I/O ### UI/Terminal Operations (BMS maps, screens) - SEND MAP, RECEIVE MAP → these can be MOCKED or stubbed …

How to install
mdr add openhands/extensions/mainframe-planning@sha256:a6e64ed015955951The line at the top of this page pins the label git:20260306.cebd78b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
