Yes but self confidence works against all this when it doesn’t come with awareness and humility around what you don’t know. You need self skepticism about opinions and new knowledge but confidence around ability to perform actions.

I think the connotations are a little different. Self-confidence can include a sort of complacency (confidence in what you're currently doing), whereas agency seems to be more a will to figure things out, whatever it takes.

I wondered the same. Seems very difficult for a person with low self-confidence to act on these recommendations.

One of the tips is assume everything is learnable - you can learn to be self-confident.

My self-confidence was in the trash during high school. In college I had a couple of experiences that gave me opportunities to learn to be confident.

The sense of difficulty is a sign of opportunity.

To some degree, but if you find that your agency is impaired by a lack of self-confidence, you can start by trying to fake self-confidence.

Self-confidence is helpful alongside agency, but I think it's a totally different concept.

Agency is about self-awareness and realizing that you have a choice. Lack of agency means going along with the default, societal script or what is handed to you even if it is not a good option for you.

One example is dropping out of a university program, even if you are capable of graduating. There is a strong social expectation that you finish, but maybe you don't like it, or your time is better spent elsewhere. Agency is that realization that you can choose.
