IMO, the power of shell is really the ability to leverage command-line tools (e.g. git, curl, jq) with very little code. These tools are very fast, well-tested, feature-rich, and often easy to install in a reproducable way.
IMO, The inflection point where you should stop using shell is very low, though. The Google style guide for shell recommends that you should rewrite scripts once they are more than 100 lines, and I think that it probably too generous.
