Arborist can populate tasks to run from top-level Makefile or mise configurations. These tasks run like commands but they are not configurable in Arborist.
How Arborist Finds Tasks
Tasks are looked for in a worktree when it is selected in Arborist. When it finds definitions from either mise or make (or both) then it shows them below your repository’s commands. The definition files are live-monitored as well so you can make changes to a Makefile or a .mise.toml and those will repopulate live in the Arborist task section.
Running a task is just like running a command: click the run button and the console will appear with the output of the task.
