#   Gemini CLI   → ~/.gemini/config/plugins/bigpowers/ (one dir symlink)
#   pi           → ~/.pi/agent/skills/<name>/ (one symlink per skill)
#   Hermes Agent → ~/.hermes/skills/<name>/ (symlink rendered .hermes/skills/)
#   ZCode        → ~/.zcode/skills/<name>/ (symlink rendered .zcode/skills/)
#   MiMo Code    → ~/.mimocode/skills/<name>/ (symlink rendered .mimocode/skills/)
