Worked on the snakemake/snakemake repository to restore rerun triggering for Python-based rules, addressing a key reliability issue in workflow automation. The solution involved caching Python source code so that any changes would correctly prompt necessary rebuilds, ensuring accurate dependency tracking. Expanded rule capture was implemented to include both shell commands and Python function definitions, which improved debugging and documentation for mixed environments. A new test case was added to validate the rerun behavior, enhancing overall traceability. The work relied on Python programming, debugging, and testing skills, resulting in reduced debugging time and improved continuous integration coverage for rule processing.
