## CI Operations

<!--
The test suite can be run using a different DACCS config with
``birdhouse_daccs_configs_branch: branch_name`` in the PR description.
To globally skip the test suite regardless of the commit message use
``birdhouse_skip_ci`` set to ``true`` in the PR description.

Using ``[<cmd>]`` (with the brackets) where ``<cmd> = skip ci`` in the
commit message will override ``birdhouse_skip_ci`` from the PR
description.
Such commit command can be used to override the PR description behavior
for a specific commit update.
However, a commit message cannot 'force run' a PR which the description
turns off the CI.
To run the CI, the PR should instead be updated with a ``true`` value,
and a running message can be posted in following PR comments to trigger
tests once again.
