I've had good luck with having Claude write little CLI tools that interact with Jira: "cases" prints out a list of my in-progress cases (including immediately printing a cached list of cases, then querying Jira and showing any stragglers), "other_changes" shows me tickets in this release that are marked with "Other changes" label, "new_release" creates a new release in Jira, our deployment database, and a script to run the release, etc...

I could imagine a subagent that builds a tool on demand when it's needed.

Claude is really good at building small tools like these.
