How to choose your first package
Start from the job, not the tool, and install the few that fit.
The most common mistake in a first setup is thinking that more skills means better results. It does not. On every request your AI looks through the descriptions of the installed skills. The longer the list, the more likely it picks the wrong one. A small set that fits your job works better than a large, scattered one.
Start from the job, not the tool. Ask yourself: what did I do most last week? Did you build a presentation, clean up a spreadsheet, write emails, prepare a job posting? The two or three jobs you do most often decide what goes into your first package.
On Skillducks you do this by picking a department. Each department package holds three skills chosen for the work that department does often. The management package, for example, has presentations, Excel spreadsheets and meeting minutes. If your department is not listed, typing what you want to make is enough.
Before you approve the package, check three things for each skill. What it does: does the description sound like your work? Whether it needs an extra program: some skills need a free program such as LibreOffice on your computer, and this is written next to the skill. Who wrote it and under which license: a skill with a clear author and source is easier to get to know.
If you are just starting, leave video and 3D skills for later. Most of them ask you to install extra programs and can be tiring as a first experience. Document, spreadsheet, presentation and writing skills need little or no extra setup.
After installing the package, use it for a week. That is when you see which skills really help. If a job turns out to be missing, you will know better what you need, and looking for a skill for it gets easier.
Do not try to install everything on day one. A good start is seeing the difference with your own eyes on a job you know well. You have done that job for years, so you are the best judge of whether the result is good.
