## Recommendations

1. **Create documentation template** based on Minijob/Prozentrechner patterns
2. **Document all 15 tools** using standardized template
3. **Add 2026 update patterns** to Cursor rules
4. **Create maintenance guide** for annual updates
5. **Document law change monitoring** process

## Next Steps

1. Create `TOOL_DOCUMENTATION_TEMPLATE.md`
2. Create individual documentation for each tool
3. Update Cursor rules with 2026 patterns
4. Create maintenance guide
