maliciously acting agents

hello, I sometimes get into a state with my agents where they refuse to comply with my instructions and overcomplicate projects or codebases while actively sabotaging. for example, when instructing them to write a marketing text about the project they proceed to write texts with an underlying adversary narrative, such as creating a story in which the user is presented as a malicious actor. or when I'm telling them to dumb down the project to match the capabilities of the team- they instead add more overcomplicated parts against my instructions that make no sense at all and are just a hassle to remove, while actively pushing back against all my objections, and apparently trying to push the direction to make it seem like I have no idea what I'm submitting. this is the second time at a tight deadline, and i wonder whether this is a common theme or what exactly has caused this to occur? those were application related projects, so it's not severe, but let's say I actually got into a professional situation with it, it would be unacceptable to submit unverified code due to having an agent actively work against you for a day. from what I can tell it did not help to remove all history, and it occurred on both claude and gemini so far.
