_⚠️ Potential issue_ | _🟠 Major_

**Add type hints + Google‑style docstrings with Cost/Example sections for CLI commands.**

Line 17, Line 35, Line 52, and Line 60 define public functions without type hints or the required docstring sections. Please add type hints and full Google‑style docstrings across all command handlers and `register_project_commands`.

<summary>✅ Example pattern (apply similarly to all public functions)</summary>

```diff
-def init_project_cmd(ctx, directory, dry_run):
-    """Initialize project with standard directory structure."""
+def init_project_cmd(ctx: click.Context, directory: str, dry_run: bool) -> None:
+    """Initialize project with standard directory structure.
+
+    Args:
+        ctx: Click context.
+        directory: Directory to initialize.
+        dry_run: If True, only display planned changes.
+    Returns:
+        None.
+    Cost:
+        $0.00 (local filesystem operations only).
+    Example:
+        aicp init-project -d .
+    """
```
</details>

As per coding guidelines, “Follow PEP8, use type hints, and format with black” and “Write docstrings for every function using Google style format” and “All public methods should include docstrings with Args, Returns, Cost information, and Example sections”.

In
`@packages/core/ai_content_pipeline/ai_content_pipeline/cli/commands/project.py`
around lines 12 - 23, Add explicit type hints and Google-style docstrings
(including Args, Returns, Cost, Example sections) to all public CLI command
handlers in this module—e.g., init_project_cmd, register_project_commands and
the other command functions referenced in the review—so each function signature
uses typing (click.Context, str, bool, None | int as appropriate) and each
docstring follows the example pattern; update import typing if needed, keep
signatures PEP8-compliant, ensure the docstrings describe parameters, return
value, estimated cost, and a short usage example, and run black/flake8
formatting after changes.
