pymatgen

Quick Review

Exceptional materials science skill with comprehensive coverage of pymatgen capabilities. The SKILL.md provides crystal-clear descriptions that enable CLI agents to invoke functionality confidently, covering structure manipulation, file conversion, symmetry analysis, phase diagrams, electronic structure, surface analysis, Materials Project integration, and computational workflows. Task knowledge is outstanding with detailed code examples, three executable scripts, and extensive references. Structure is well-organized with logical progression from basics to advanced topics, clear indexing of bundled resources, and appropriate separation of detailed documentation into reference files. The skill offers significant novelty by consolidating complex materials science operations (crystal structure analysis, phase diagram generation, electronic band structure interpretation) that would otherwise require many tokens and domain expertise from a CLI agent. Minor improvement possible in making the initial overview even more concise given the excellent reference system. The skill meaningfully reduces cost for computational materials science tasks while maintaining clarity and completeness.
