+# "Check Poetry" workflow (Task)
+
+Check for problems with configuration files of the [**Poetry**](https://python-poetry.org/) Python package manager.
+
+This is the version of the workflow for projects using the [Task](https://taskfile.dev/#/) task runner tool.
+
+## Installation
+
+### Workflow
+
+Install the [check-poetry-task.yml](check-poetry-task.yml) GitHub Actions workflow to `.github/workflows/`
+
+### Assets
+
+- [`Taskfile.yml`](assets/check-poetry-task/Taskfile.yml) - Validation tasks.
+  - Install to: repository root (or merge into the existing `Taskfile.yml`).
+- [`Taskfile.yml`](assets/poetry-task/Taskfile.yml) - Installation task.
+  - Merge into `Taskfile.yml`

+## Commit message
+
+```
+Add infrastructure for checking Poetry configuration files
+
+The project's Python package dependencies are managed using the "Poetry" tool.
+
+Tasks and a GitHub Actions workflow are added to maintain and check for problems in the Poetry configuration files.
+
+The tasks provide the following operations:
+
+* Check for problems with the data structure of the `pyproject.toml` Python project file
+* Update the `poetry.lock` file as may be required following manual modifications to `pyproject.toml`, or update of the
+  "Poetry" application
+
+These tasks are executed by the GitHub Actions workflow on any push or pull request that modifies relevant files, and
+periodically to check for breakage caused by external changes.
