coverage-file-name	The name of the file containing the code coverage results.	yes	coverage.txt
root-package	The Go import path of the tested repository to add as a prefix to all paths of the changed files. This is useful to map the changed files (e.g., ["foo/my_file.go"] to their coverage profile which uses the full package name to identify the files (e.g., "github.com/fgrosse/example/foo/my_file.go"). Note that currently, packages with a different name than their directory are not supported.	no	github.com/${{ github.repository }}
skip-comment	Skip creating or updating the pull request comment. This may be useful when you want to generate the coverage report and modify it in your own scripts.	no	false
trim	Trim a prefix in the "Impacted Packages" column of the markdown report.	no	—
exclude	Exclude files matching the given regular expression from the report.	no	—
github-baseline-workflow-ref	The ref of the GitHub actions Workflow that produces the baseline coverage. By default, the GitHub Actions Workflow ref is used (e.g. "octocat/hello-world/.github/workflows/my-workflow.yml@refs/heads/my_branch"). You can aso just pass the name of the Workflow file directly (e.g. "my-workflow.yml").	no	${{ github.workflow_ref }}
event-name	The event that triggered the workflow used to filter baseline runs.	no	push
target-branch	The base branch to compare the coverage results against. Defaults to github.base_ref, which is only set on pull_request events. For other event types (e.g. push, schedule), set this explicitly.	no	${{ github.base_ref }}
