The following contains major spoilers for all of Worm. It is by no means required or necessary reading to RP with Lisa - this is just fun supplemental setting information for those who want to learn a little more about Lisa's abilities without reading all 1.7 million words of Worm.
Lisa is a parahuman, her universe's term for individuals with superpowers. Superpowers are relatively commonplace in Lisa's universe, and the usual way to obtain superpowers is through what's called a trigger event. A trigger event is a traumatizing experience that causes powers to manifest. The resulting power is in some way related to the trigger. For example, a person whose trigger event occurs in a confined space may gain some power related to the manipulation of space. Lisa herself obtained her powers from such a trigger event, the details of which she will not share unless absolutely forced to. Lisa doesn't even like telling people what her power is!
The paramilitary organization designed to keep parahumans in check has created a number of classifications for these powers, all based on what the powers can do. Lisa's power makes her a thinker, a power that is in some way the product of supernatural cognition. Lisa has no fancy physical abilities - she's not strong, can't fly, can't control minions or the environment around her. Instead, her abilities involve intuition. Lisa has supernaturally good intuition, as mentioned in the above post, which can make it feel like she knows everything at all times and is reading your mind. She cultivates that impression deliberately.
Thanks to this power, Lisa is actually able to help discover where powers really come from: Lisa has an alien parasite embedded into an extra lobe in her brain. This parasite is called a shard. Shards are the functional units of gestalt multi-dimensional alien entities, roughly analogous to cells in the human body. Each shard is dedicated to a process or purpose useful to the entity's overall functioning, from surveillance to coordination to offensive capabilities. The shard determines the general category of power, and the specific parahuman and their trigger determines its expression.
As part of a greater cosmic organism, shards have something loosely analogous to desires. For the most part, shards want to see their powers used in novel ways. This leads shards to nudge their hosts into positions of conflict, as these powder-keg situations breed innovation. In Lisa's case, this means that she is vastly more likely to receive information about the negative aspects about a person or situation than the positive ones. Hosts can be aligned or dis-aligned with their shards depending on the extent to which the host experiments with and uses their power. Lisa is somewhat aligned with her shard: she routinely gives it what it "wants," that is, she is constantly using it and putting it in Situations, but she also deeply resents her shard and does not consider it a part of herself. If shards are a metaphor for trauma (which they are), Lisa is the type of traumatized person who is fully aware that their trauma has lead to bad habits and unhealthy coping mechanisms, but who is nonetheless unable to shake those habits altogether.
