-Stage the collection in your library first, then add the skills you want:
-
-```bash
-swival skills add --global https://github.com/DietrichGebert/ponytail  # stage into ~/.config/swival/library
-swival skills add ponytail                                             # install the collection into this project
-swival skills add --global ponytail                                    # or activate it in every project

-Swival also reads `AGENTS.md` from the project root and `~/.config/swival/AGENTS.md` globally, the instruction-only fallback.

-On the command line, use a `$` prefix with the plugin namespace to explicitly activate a skill. For example: `$ponytail:ponytail-review`.
