 # Action: Setup Project (composite action)
 #
-# Purpose: Bootstrap a Python project in GitHub Actions by:
-#   - Installing Task, uv, and uvx into a local ./bin directory
-#   - Detecting presence of pyproject.toml and exposing it as an output
-#   - Creating a virtual environment with uv and syncing dependencies
+# Purpose: Bootstrap a Python project within GitHub Actions by:
+#   - Installing uv and uvx into a local ./bin directory and adding it to PATH
+#   - Detecting the presence of pyproject.toml and exposing that as an output
+#   - Creating a virtual environment with uv and (optionally) syncing dependencies
 #
 # Inputs:
-#   - python-version: Python version used for the virtual environment (default: 3.12)
+#   - python-version: Python version for the uv-managed virtual environment (default: 3.12)
 #
 # Outputs:
 #   - pyproject_exists: "true" if pyproject.toml exists, otherwise "false"
 #
 # Notes:
 #   - Safe to run in repositories without pyproject.toml; dependency sync will be skipped.
-#   - Used by workflows such as CI, Book, Marimo, and Release.
+#   - Purely a CI helper — it does not modify repository files.
