The Agent Skills Directory

[SAFE]: The skill provides standard functionality for computational materials science, serving as a wrapper for the widely-used pymatgen Python library.
[EXTERNAL_DOWNLOADS]: The skill recommends installing pymatgen and mp-api from the standard Python Package Index (PyPI). These are well-known, legitimate libraries in the scientific research community.
[COMMAND_EXECUTION]: The bundled scripts (structure_converter.py, structure_analyzer.py, and phase_diagram_generator.py) provide command-line tools for processing structural data files and fetching data from external APIs. These tools operate on standard file formats (CIF, POSCAR) and perform expected tasks related to the skill's purpose.
[DATA_EXFILTRATION]: The skill facilitates network requests to next-gen.materialsproject.org via the official MPRester client. This is the intended behavior for accessing Materials Project data and does not represent an exfiltration risk in the context of its stated functionality.
[PROMPT_INJECTION]: The skill processes external structure files which are used to populate the agent's context. While this represents a potential surface for indirect injection, the risk is low as the data is parsed through specialized scientific libraries rather than being directly interpreted as instructions.
