FAIR Simulation Packager
Goal
Build a minimal reproducibility manifest for materials simulation results so another person or agent can understand what was run, with which inputs, and how outputs should be interpreted.
Requirements
- Python 3.10+
- No external dependencies
- Works on Linux, macOS, and Windows
Inputs to Gather
| Input | Description | Example |
|---|---|---|
| Project name | Human-readable bundle name | al-cu-diffusion-study |
| Engine | Simulation code | LAMMPS, VASP, MOOSE |
| Input files | Files needed to rerun | in.lammps,data.lmp |
| Output files | Files needed to verify results | log.lammps,traj.dump |
| Structure ID | Database or local identifier | mp-149 |
| Units | Field/unit mapping | energy=eV,length=angstrom |
Decision Guidance
- Always include input files, output files, code version, and units.
- Include hashes for every file that exists locally.
- Include structure identifiers when using Materials Project, NOMAD, OPTIMADE, CIF, POSCAR, or internal database records.
- Record missing files as warnings instead of silently dropping them.
Script Outputs
scripts/fair_packager.py emits:

Workflow
python3 skills/data-management/fair-simulation-packager/scripts/fair_packager.py \
--project-name al-cu-diffusion \
--engine LAMMPS \
--inputs in.lammps,data.lmp \
--outputs log.lammps,traj.dump \
--units energy=eV,length=angstrom,time=ps \
--structure-id local:alcu-cell-001 \
--json
Use --out manifest.json only when the user wants a manifest file written.
Error Handling
Missing files are reported in missing_files; invalid unit fields or unsafe paths stop with exit code 2.
Limitations
This skill creates a metadata manifest. It does not upload to NOMAD, Materials Project, or an OPTIMADE provider.
Security
- File paths are read only for metadata and SHA-256 hashing.
- The script rejects control characters and oversized files above 500 MB.
- Optional manifest writing is restricted to the requested output path.
- The skill uses
Bashonly to run the bundled script.
