End-to-end COBOL to Java migration workflow. Handles build setup, mainframe dependency removal, and code migration with test validation.
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
End-to-end workflow for migrating COBOL codebases to Java. ## Overview This plugin orchestrates a multi-phase COBOL modernization project: 1. **Build Setup** — Configure compilation for both COBOL and Java, create test fixtures 2. **Mainframe Planning** — Document transformations needed to remove mainframe dependencies 3. **Mainframe Removal** — Convert CICS/VSAM code to standard COBOL 4. **Java Migration** — Translate standardized COBOL to idiomatic Java ## Prerequisites - GnuCOBOL compiler (`cobc`) - Java 11+ with Maven or Gradle - Python 3.13 with `uv` - LLM API key (Anthropic or OpenAI) ## Quick Start ```bash export LLM_API_KEY="your-api-key" export LLM_MODEL="anthropic/claude-3-5-sonnet-20241022" uv run python -m lc_sdk_examples.cobol_modernization --src-path /path/to/cobol/project ``` PowerShell equivalent for the environment setup: ```powershell $env:LLM_API_KEY = "your-api-key" $env:LLM_MODEL = "anthropic/claude-3-5-sonnet-20241022" uv run python -m lc_sdk_examples.cobol_modernization --src-path C:\path\to\cobol\project ``` ## Workflow Phases ### Phase 1: Build Setup See [../build-setup/SKILL.md](../build-setup/SKILL.md) …

How to install
mdr add openhands/extensions/cobol-modernization@sha256:551452a767707ba2The line at the top of this page pins the label git:20260701.599cc4d, 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.
