## Summary
Rebased version of #19051 with all review comments addressed. Clean
branch on latest main, lint/typecheck/tests passing.
### Changes from original PR
- AI can now create, update, and delete **view filters**
(`ViewFilterToolsFactory`) and **view sorts** (`ViewSortToolsFactory`)
- `create_view` now accepts `calendarFieldName`, `calendarLayout`, and
`fieldNames` to configure views at creation time
- Three new standard skills: `view-building`, `view-filters-and-sorts`,
`custom-objects-cleanup`
- `workspace-demo-seeding` skill reworked to keep standard objects and
enrich them with custom fields
- Cache invalidation for nav menu items when object `isActive` changes
- Dashboard tool descriptions improved (RECORD_TABLE widget workflow)
### Review comments addressed (all 10 from #19051)
1. **Sentry + Cubic**: Calendar field DATE/DATE_TIME validation — added
`resolveCalendarFieldMetadataId` using `isFieldMetadataDateKind`
2. **Cubic**: "navigate tool" → "navigate_app tool" in skill metadata
(all 7 occurrences)
3. **Copilot**: KANBAN views now require `mainGroupByFieldName` — throws
clear error if missing
4. **Copilot**: CALENDAR views now require both `calendarFieldName` and
`calendarLayout` — validated before DB call
5. **Copilot**: Mock field fixtures include `type` property (DATE_TIME,
TEXT, SELECT)
6. **Copilot**: `ViewFilterValue` type assertion instead of unsafe `as
string` casts (3 locations)
7. **FelixMalfait**: Removed
`NavigationMenuItemObjectDeactivationListener` — replaced with cache
invalidation
8. **FelixMalfait**: Consolidated `ViewFilterToolProvider` and
`ViewSortToolProvider` into single `ViewToolProvider`
9. Removed `VIEW_FILTER` and `VIEW_SORT` from `ToolCategory` enum
(merged into `VIEW`)
10. Removed stale `existingFeatureFlagsMap` param incompatible with
current main
## Test plan
- [x] `npx nx lint:diff-with-main twenty-server` — passes
- [x] `npx nx typecheck twenty-server` — passes
- [x] `view-tools.factory.spec.ts` — all 20 tests pass (including 3 new
validation tests)
