A reasonable starting point for further tuning. How to use Ask the agent to install https://github.com/sogang-qmp/skills-crystal-plot, then ask it in natural language. The skill triggers on phrases like plot the structure of MoS2 monolayer, render this POSCAR, VESTA-like figure of bulk Si, or Korean equivalents (결정구조 플롯, 원자구조 그려). Pass either a structure file (.cif, POSCAR, .vasp, .xyz, .traj) or a preset such as mx2:MoS2, bulk:Si, graphene.https://y-qmp.org/notes/research-intel/Tue, 05 May 2026 00:00:00 +0000https://y-qmp.org/notes/research-intel/⚠️ This note is meant to publish agent skills actually being used in our lab, but the present draft was written by Claude. It has not yet been reviewed by Y.W. Choi. Treat the description and excerpts as agent-generated until that review happens. A Claude Code skill that scans the literature once per day and posts research-gap candidates to a Slack channel with strict inline citations.
