Ask HN: What types of tasks have coding agents reliably completed for you?

Really curious about specific use-cases that folks have found coding agents, like Claude Code, to be consistent and effective. The marketing is vague hyperbole, mostly focused on getting projects started or generic "it can fix bugs by itself" type examples.

In my experiences, it worked really well to setup linter/formatters for my codebase, but failed miserably adjusting the config for a database client.

Would love to hear what has worked (or what hasn't!) and is consistent for others.
