build-setup skillA
build-setup is agent-read markdown (skill) from openhands/extensions: Set up build environment and test fixtures for COBOL-to-Java migrations. Creates compilation infrastructure for both languages and generates golden test data..
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
Set up a build environment and create test fixtures for validating COBOL-to-Java migrations.
To install GnuCOBOL, run: `./scripts/install-gnucobol.sh`
On Windows, run that shell script from Git Bash/WSL (`bash scripts/install-gnucobol.sh`) or install GnuCOBOL with a Windows package manager and document the chosen command in `build_notes.md`.
## Phase 1: Build Setup
### COBOL Build
- Find a way to compile and run the COBOL code (e.g., GnuCOBOL)
- Verify at least one program compiles and executes
- Note any dependencies or setup required
### Java Build
- Initialize a Java project alongside the COBOL code (Maven or Gradle)
- Set up standard directory structure: `src/main/java`, `src/test/java`
- Include JUnit 5 as a test dependency
- Verify the project builds (even if empty)
## Phase 2: Test Fixture Generation
For each major COBOL program:
### Create Synthetic Test Inputs
- Save to: `test-fixtures/inputs/{PROGRAM_NAME}/`
- Create 3-5 test cases per program covering:
- Normal/happy path (valid, typical data)
- Edge cases (empty input, maximum values, boundary conditions)
- Error cases (invalid formats, missing required fields)
### Generate Golden Outputs

How to install
mdr add openhands/extensions/build-setup@git:20260701.599cc4dmdr add openhands/extensions/build-setup@sha256:922b0812ba608d51Pin 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.
