# Task: Add Internal Import Path Warning

## Problem

The spec shows importing errors from `youtube_transcript_api._errors`, which is an internal/private module path (indicated by the underscore prefix). While this currently works, internal APIs can change without notice.

## Solution

Add a warning note about the import path stability in FEAT-SKEL-003.

## Content to Add

Add this note after the error import example:

```markdown
### Error Handling Imports

```python
from youtube_transcript_api._errors import (
    TranscriptsDisabled,
    NoTranscriptFound,
    VideoUnavailable,
    NoTranscriptAvailable,
)
```

> **Note**: These imports use an internal module path (`_errors`). The underscore
> prefix typically indicates a private API that could change. However, the
> youtube-transcript-api library has kept this interface stable across versions.
> If a future version changes the import path, update accordingly.
>
> Alternative: Wrap imports in try/except for version compatibility:
> ```python
> try:
>     from youtube_transcript_api._errors import TranscriptsDisabled
> except ImportError:
>     from youtube_transcript_api.errors import TranscriptsDisabled  # Future?
> ```
```

## Where to Add

In FEAT-SKEL-003, locate the "Error Types" table (around line 632-639) and add this note directly after the table.

## Acceptance Criteria

- [x] Warning note added about internal import path
- [x] Alternative import pattern shown for future-proofing
- [x] Note explains why this is currently acceptable

## Implementation Summary

Added warning note after the Error Types table at line 711 in FEAT-SKEL-003-transcript-tool.md:
- Explains that `_errors` is an internal module path
- Notes that the library has kept this interface stable
- Provides alternative try/except import pattern for future compatibility

## Completion Details

- **Duration**: ~5 minutes
- **Files Modified**: 1 (docs/features/FEAT-SKEL-003-transcript-tool.md)
- **Lines Added**: 12
- **Complexity**: Trivial (documentation only)
