They kind of were one-shotted by Claude. The value is in coming up with a consistent design and good enough --help that you can prompt:
Run uvx showboat --help and
uvx rodney --help and use those
tools to demo the feature you built
The help text effectively doubles as a skill.
I guess it would still make sense to have "demo" and "browser-use" skills, so that the agent can reach for them proactively? I always try to remove as much friction as possible for myself, one little bit at a time.
