cobol-modernization skillA
cobol-modernization is agent-read markdown (skill) from openhands/extensions: End-to-end COBOL to Java migration workflow. Handles build setup, mainframe dependency removal, and code migration with test validation..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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@git:20260701.599cc4dmdr add openhands/extensions/cobol-modernization@sha256:551452a767707ba2Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
