Lifeskills and part-time jobs

A skill being 'affected by others' and items being required to craft X or Y is very different; the first does not occur at all in the game.

I'll use Handicraft as an example; on a character that is freshly new, with rank F handicraft, even without having learned Weaving or other production life skills, the crafting list will show everything that the player can craft, regardless of their rank or what skills they have. Spider Traps will show in the list regardless of the player knowing Spider Shot.

Although the player will not be able to craft certain items with their current rank, but that is normal; The player does not have to source the materials themselves; that's what trading and selling life materials always was for.

Other than some exceptions with phantasmal sight being required to see certain recipes (which is a part of that skill's gimmick to start with), what you wrote comes across as very confusing statements.

Ascon's part time job, thick-spar part-time job. The new player can have the task/ptj but will not be able to do anything nor use anything since the recipe is not available to them. Is one reason I want to address this. There is also light silk part time job that was finally unlocked until I got weaving at a higher rank.

Part-time jobs effectively do not check your skill rank, so that can happen, yes. That doesn't mean the skills are interdependent the way you describe it.
