-# Describes the tasks we run in the continuous integration (CI) environment.
-#
-# Cocoon[1] uses this file to generate a checklist of tasks to be performed for
-# every master commit.
-#
-# [1] github.com/flutter/cocoon
-
-# CI tasks.
-#
-# Each key in this dictionary is the unique name of a task, which also
-# corresponds to a file in the "bin/" directory that the task runner will run.
-#
-# Required properties:
-#
-# * description: free form string
-#       describes what the task is about
-# * stage: one of "devicelab", "devicelab_ios", "devicelab_win"
-#       tasks are grouped by stage so they appear next to each on the dashboard and have a distinct
-#       icon attached to them. Stages can be used to create dependencies, e.g. we may decide to not
-#       run device tests on red Cirrus builds.
-# * required_agent_capabilities: a list of strings
-#       list of capabilities a devicelab agent must have to be able to run this task.
-#
-# Optional properties:
-#
-# * flaky: boolean true or false
-#       whether the task is considered flaky; the result of running a flaky task does not affect
-#       the overall build status. Tests should be marked flaky when newly added, until they have
-#       been proved for a few cycles. Tests that are actually flaky but not being actively worked
-#       on should be hidden because they just cause confusion otherwise.
-# * on_luci: boolean true or false
-#       whether the task runs on LUCI builders. Tests will be gradually marked on_luci during the
-#       devicelab to LUCI migration. And when the migration is complete, on_luci flag will be
-#       removed.
