item.css("td::text")[2].get()may cause an index error if the HTML structure changes. Ensure proper error handling or validation.

1-2: No issues found.
79-81: Nice comprehensive coverage with parameterized testing.
Parameterizing the test_all_day function ensures that each item is thoroughly confirmed to be non-all-day. This is a well-structured approach to testing across all parsed items.

12-12: Verify the timezone matches the board’s actual location.
Hamilton County is located in Eastern Time (America/New_York). The spider is set to America/Chicago, which might be incorrect.

🛠️ Refactor suggestion
Use “is None” instead of “== None”.
Pythonic best practices recommend checking for None using is None rather than using equality.
Apply this diff to adjust the comparison:
-assert parsed_items[0]["end"] == None
+assert parsed_items[0]["end"] is None📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Good job on this one. Everything looks good here. I would just say pay more attention to your PR description next time. The manual test instructions could have had more detail.

💡 Codebase verification
Fuzzy date parsing is unnecessary and potentially risky for this structured data source
The date comes from a structured government website table, and tests show that precise timestamps are expected (e.g., 2025-01-07 10:00). Using fuzzy parsing could lead to silent failures if the date format changes. Consider using strict parsing with an explicit format string instead.
🔗 Analysis chain
Consider using explicit date parsing instead of fuzzy parsing.
Using fuzzy=True in date parsing could lead to incorrect results if the date format changes. Consider parsing the date explicitly using the expected format.
🏁 Scripts executed
The following scripts were executed for the analysis:

I noticed that the CI checks are still failing. Before pushing your commits, please run these code quality checks locally:
pipenv run isort . --check-only # Check import sorting
pipenv run black . --check # Check code formatting
pipenv run flake8 . # Check code style
What's this PR do?
This PR creates a new scraper for the Hamilton County Board of Commissioners, URL: https://hcjfsonbase.jfs.hamilton-co.org/OnBaseAgendaOnline
Why are we doing this?
Scraper requested from this spreadsheet.
Steps to manually test
Monitor the output and ensure no errors are raised.
Inspect
test_output.csvto ensure the data looks valid.Are there any smells or added technical debt to note?
The links for Agenda, Minutes, and Media all link to the same page, so only one of those links is scraped.
