Start by reading .github/workflows/milestone-changelog.md and inspecting run 33931735027 to locate the batch-writing command that requires bash. Replace that command as indicated with Python subprocess calls and direct file writes, then rerun the Milestone Changelog Generator workflow and confirm it completes without missing-tool failures.
