Ah I don't delete these or really look at the `.tickets/` directory. I have about 1900 tickets in one project and navigate them through VS Code. Ctrl+t does fuzzy finding across all markdown headers and I Crtl+Click in the terminal quite a lot to jump to ticket files.

But yes, dependencies are everything here. I use `tk dep tree` regularly to visualize the graph and click on the things I want details on. Typically I don't have too crazy of a list of open tickets so it's easy enough to find things by running `tk ready` and `tk blocked` and clicking what I'm looking for. For historical things, I just search in the `git log` pager.

If it'd be useful though, I can look at a `tk delete` command that deletes a given ticket and all of its dependencies to clean up a whole tree in one shot. Not sure I'd ever use it myself though.

I'd find it handy. I think there's some risk in agents tripping over stale tickets and consuming tokens - I see it with .md all the time.

Tickets by dependency would be nice (although my agent hasn't really used dependencies yet), and ideally something to just quickly wipe out closed tickets with a single command would be nice.
