The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill installs the pymatgen and mp-api libraries from the Python Package Index (PyPI). These are official, widely-used, and trusted libraries within the materials science community.
[CREDENTIALS_SAFE]: The skill correctly instructs users to manage Materials Project API keys via environment variables (MP_API_KEY), which is a recommended security practice to prevent credential leakage.
[COMMAND_EXECUTION]: The included Python scripts perform standard file input/output and data processing operations for materials analysis. These activities are entirely consistent with the skill's stated purpose.
[SAFE]: No malicious patterns, such as prompt injection, data exfiltration, or obfuscation, were identified. The skill acts as a legitimate interface for scientific research tools.
