You may gain skill even failing an action; though, it can vary per skill.
Stamina affects skill gain. <strike>The less stamina you have at the beginning of an action the more skill you will receive. As long as you have at least 1% stamina at the beginning of the action you will receive skill. If you perform actions at 0% stamina you receive no skill.</strike> It is still possible to gain skill if you start an action while having 0% stamina, however the penalty to the skill tick is massive.
Here are 3 examples of skill ticks at various points of stamina usage with sleep bonus on:
*100% stamina -- [23:22:30] Mining increased by 0.000908 to 90.10496
