I want to know if a certain command is cached (aka turbo will not run it from scratch) before executing that command.

Example: I want to check if site is built.

I can use --dry-run to check, and that works. However it is incredibly slow (11 seconds in this particular repo):

pnpm turbo run build --filter=site --dry-run=json | jq '.tasks[-1].cacheState.local'
# true

At the same time, if I just do:

pnpm turbo run build --filter=site

turbo can almost instantly tell if build is cached or if it needs to be re-executed. So obviously turbo doesn't actually need 11 seconds to get the info I want. --dry-run is probably doing much more stuff that I'm not interested in this particular instance.

So, how can I make turbo output the info I want without waiting that long?

For context: If the answer is no, I want to abort and exit. There are some scripts (ex. testing) that hide the build output. So for those, I'm fine with them spinning up a dev server before running tests if they can grab it from cache and all is fresh, but I don't want them to actually build. In the latter case, I want to abort.
