MD skills
2026-7-27:
封装了一个轨迹处理的skill：Skill created at ~/.config/opencode/skill/md-traj-process/
SKILL.md. Restart opencode to use it.
1. 重启 opencode 使 skill 生效
2. 对话时提到 traj、trjconv、PBC、RMSD 等关键词会自动触发
3. 或手动加载：skill md-traj-process
例如：
- "帮我处理 MD 轨迹，strip water"
- "用 gmx trjconv 修复 PBC"
- "计算 RMSD"
