For your YouTube clients, I'd break the work into three parts:
Channel management: Checking channel performance, organizing content, and helping with routine tasks.
Data reporting: Collecting views, watch time, subscriber growth, and engagement, then turning the numbers into clear reports.
Client support: Organizing tasks, preparing updates, and keeping track of deadlines.
My suggestion would be to test OpenClaw and Hermes Agent on the same small task before making a decision. For example, ask each to collect YouTube channel statistics and prepare a weekly performance report. Compare accuracy, setup difficulty, integrations, and how much human supervision each requires.
I'd also keep approval in place before either agent publishes content or changes important channel settings.
One question: Will this agent manage several clients' YouTube channels at the same time, or will you start with one channel and expand later?
That detail would help determine which setup makes more sense.
