No, they run without error (apparently). That is an entirely different
In particular, "ssh-agent -s" starts an agent but unless you make use of
its output, your subsequent commands will have no idea how to access it.
Since ssh-add (apparently) works, then I would guess you _already_ had
an agent, and it is adding to that agent's keys. And, importantly,
_ignoring_ the new agent you started.
Try running your commands above again, but _before_ them, run "ssh-add
-l". If that works then there's already an agent known to the shell and
your subsequent "ssh-add" is likely adding to that, not to the new agent

I'm presuming that as with UNIXy systems, os.system() on Windows issues
its commands to a distinct shell ( instance of cmd.exe or the like).
As such, since you've made no effort to catch and parse the output of
"ssh-agent -s" you don't know how to talk to the agent you started, and
further since you don't pass any information to the shell running
"ssh-add" then it doesn't know how to do that either.
