Garbage collection is a periodic action you must perform. It cleans up tasks and big plans that are completed and otherwise lingering on in the system.
It needs to be performed weekly usually.
In the web app you can find reporting in the
Garbage Collect left-hand side tab, under tools. It looks
something like this:
After pressing the
Garbage Collect button, completed inbox tasks and big plans are archived. This makes
them invisible for most views.
The CLI command is called
gc and has the same capabilities as the Web App.
The command is idempotent, so you can run it however many times you want and it'll do the right thing. Furthermore it does not affect task status, or any extra edits on a particular instance of a task, besides marking some entities as archived.
