I'm sorry but I'm really not clear on what you're trying to say. If you go to the Skills page (look at the menu above) and hover over each skill, it tells you what it is and does. If you're looking for something more detailed and specific than that, I'd say to check the popular Glitch Wiki (the link to which I do not currently have but you can find easily by searching the forums for "wiki").
The encyclopaedia will show you which skills and achievements are needed for which tool. To my knowledge there is not a "walkthrough" available that shows you in what order things are done, as it is free choice when it comes to which skill path to choose when.
Thanks HB, I meant there wasn't a guided "do this in this order and then you won't have to think about it" kind of walkthrough. Not had my coffee yet this morning.
