Might be worth opening an issue, the project states it aims to aggressively cache dependencies: https://docs.astral.sh/uv/concepts/cache

Maybe that functionality isnt implemented the same way for uvx.

You could try this equivalent command that is under "uv run" to see if it behaves differently: https://docs.astral.sh/uv/concepts/tools/#relationship-to-uv...

I haven't been able to find any kind of rhyme or rhythm to it, so I don't know how to explain when it happens or how to better debug it for a bug report.

Initially, I used `uv tool run <name>`, but later discovered `uv tool install <name>`. The `install` command downloads dependencies once and caches them for future use. It is similar to how `pipx install <name>` works.

e.g.

$ uv tool install asciinema

$ asciinema play example.cast
