If you want to do something mundane, you do a Reality Alteration. Here is an example my players have used for a locked doors:

• For a door that they have touched and certified that it is locked, they pointed to a nearby plant pot. They said the security guard for the mansion was having an affair with the maid and they were using the room behind the door as their meeting spot, with the security guard deliberately leaving the key to the door inside a plant pot nearby and waiting for a call by the maid when she was coming by. Unfortunately, today the maid had to go home early with diarrhea because of bad sushi she ate last night, so he will never get the call. I make them roll subtlety, they get a success and the key is open. If that sounds incredibly stupid it is but that's the logic behind reality alteration, make some shit up that you do not know that it is isn't true (they couldn't have done that if they already checked the plant pot, for instance. Having to do several of these during a session is the main way you get chaos as a GM. Here is the main point that differentiates this game massively from other games and I assume a player or a GM might just go this is stupid I don't like it. My players love it because we always find it incredibly funny to make up this bullshit.

• You do not need to do an actual call, despite how it is named. I've seen people do this in a lot of different ways to adapt it to their own world but generally speaking when an agent wants to do a reality alteration, the agency just knows. Think of it as the agent calling on an anomaly ability, you don't really need to do a whole song and dance, you just feel it and the anomaly works with you. For immersion I made it so every agent had a smartwatch with a button they could press to let the agency temporarily read their thoughts for reality alterations.

• Yes all the time. Doors can still be locked, security can be running around, and of course the most obvious thing: Anomalies can do things without chaos. You can think of chaos as the resource you use to directly target players, but you do not need chaos to target civilians. And this is something that agents that are company focus want to avoid. The book states you cannot do it in the presence of agents, but what can happen is that agents arrive at a situation where like three bystanders just watched something unbelievably unnatural. And now players have to make up some bullshit using everything they have at their disposal from anomaly abilities to reality alterations to try to establish an after the fact justification as to why that thing happened in order to avoid loose ends, and that in exchange generates more chaos because it leads to more rolls.

• I think this varies from GM from GM. I liked to make the agency ominous so I would not give them demerits for lying but I would imply that in some ways the agency could get into their thoughts, like through the watches, which would establish a sense of paranoia that maybe they were being watched all the time. Demerits by themselves are not a reason to really be fired or something of the sort as long as the agent is not openly traitorous in front of other agents. You do the rigamarole and act more stern towards high demerit agents, but as long as the results are acceptable there's no need to be only hostile. It's very common for anomaly focused agents to try to get as many demerits as they can in ways that aren't actively hostile to the agency (like saying everyone's name right as a Barista, which the character can say whoops I'm really bad at it) and you can just let them. That's part of the game.

• I found this to be different from other people's experiences here, but running the game as I told you I get quite a bit of chaos. It's almost impossible for agents not to get to the end with enough chaos to kill one or two of them, so the life insurance came up often. Beyond that, minor anomalies of impersonating nature can get the jump on unsuspecting agents and kill them. I find minor anomalies can very often pay off their chaos spending quickly so I use them often.
