OpenClaw has surprisingly few "dumb" bugs. Is it as stable and secure as the Linux kernel? God no, obviously not. But it has never just crashed for me, for example. Bugs are of the type "X with Y and Z disabled and T turned on - doesn't work", where you're likely one of a few people that have ever tried this combination. Not to mention it can then debug itself and file a bug report, with a bugfix - if you give it a GitHub token.

I run it in a firewalled VM and am very conscious about any tokens I give it access to - so far for all I know this was unnecessary.

PS. for me the core feature of OpenClaw isn't the cron, though that is nice. It's the memory and instant extensibility. Like it takes 5-15 minutes to add an SSH tool where all agent requests go through a manual review, together with a good auto loaded description that just works in all future sessions.
