# refactor(core): improve docstrings for HTML link extraction utilities ## Description This PR updates and clarifies the docstrings for `find_all_links` and `extract_sub_links` in `libs/core/langchain_core/utils/html.py`. The previous return-value descriptions were vague (e.g., "all links", "sub links"). They have now been revised to clearly describe the behavior and output of each function: - **find_all_links** → “A list of all links found in the HTML.” - **extract_sub_links** → “A list of absolute paths to sub links.” These improvements make the utilities more understandable and developer-friendly without altering functionality. ## Verification - `ruff check libs/core/langchain_core/utils/html.py`: **Passed** - `pytest libs/core/tests/unit_tests/utils/test_html.py`: **Passed** ## Checklists - PR title follows the required format: `TYPE(SCOPE): DESCRIPTION` - Changes are limited to the `langchain-core` package - `make format`, `make lint`, and `make test` pass
