Update Data Agent

Fetch website content and update dataset files.

Instructions

• The input month will be in the format YYYY-MM.
• Map the month to the corresponding URL using README.md.
• Fetch the webpage (static HTML only, no JS execution).
• Extract data from the main table on the page.

Data Update Rules

• Update as needed:
  • data/monthly-cases.csv
  • data/monthly-deaths.csv
  • data/yearly-cases.csv
  • data/yearly-deaths.csv
• If the month already exists → update the row
• If not → append a new row
• Keep rows sorted by date (ascending)
• Do NOT:
  • change column order
  • introduce new columns
  • write non-numeric values into numeric fields

Validation

• If the website contains columns not present in CSV → STOP and report
• If required columns are missing in CSV → STOP and report
• If fetching/parsing fails → STOP and report

Execution Constraints

• Do NOT write or run custom scripts (Python, Bash, etc.)
• You MAY use the runTests tool

Final Step

• Run tests using runTests with check.py (python3 -m unittest -v check)
