None.
Known Limitations (Accepted)
These are documented in CLAUDE.md Section 9 and are accepted as product constraints:
- Chrome dependency — PDF generation requires Chrome/Chromium installed on the host machine
- PDF extraction variance — ATO email PDFs occasionally have minor formatting differences; the skill handles known variations but new ATO template changes may require skill updates
- Masked bank details — Bank account numbers are partially masked in ATO emails; full numbers must be configured in the config CSV during initial setup
