Backend
Java/Spring in backend/src/main/java/com/odde/donut/. Tests under backend/src/test/. Schema changes: db-migration skill.
Matching backend-code (production Java) and backend-testing (tests) skills attach via paths when those files are in context — do not fetch them up front.
Commands
CURSOR_DEV=true nix develop -c pnpm backend:test_only
When a database migration is involved:
CURSOR_DEV=true nix develop -c pnpm backend:verify
Always run all backend unit tests, not a selected file or test case.
Production
- Controllers: return entities (or existing API body types). Narrow with
@JsonIgnore/@JsonView. Introduce a response DTO only when the wire shape differs. - Top-of-file imports. No inline fully qualified class names except when two types share a simple name.
- After Flyway schema changes, regenerate
docs/database-erd.mdwith thedatabase-erdskill (pnpm export:database-erd). - Note collections name their trash semantics.
NoteRepository.findAllByNotebookIdOrderByIdAscis the complete stored content, trash included (export, Git snapshots, learning-session title recognition);findAvailableNotesByNotebookIdOrderByIdAscand theNote.JPA_AVAILABLE/NATIVE_AVAILABLEpredicates select participating notes (search, recall, health rules);findOccupiedFolderIdsByNotebookIdcounts stored content for folder occupancy. On a loadedNote,isTrashed()follows current folder ancestry andisTrashedInDatabase()is the persisted membership as loaded. Root_trashmembership is owned byFolder.isTrashedand thetrashed_folderview; do not recreate the rule in callers.
Tests
Small-test style (unit-testing skill): prefer controller (HTTP-stable-boundary) tests; cover services/repos via realistic makeMe preconditions and the real DB (@Transactional). Test a service/algorithm directly only when it is an intentional domain-stable contract.
Mock only external services — OpenAIClient via OpenAiStructuredResponseMock. Ownership: notebookOwnedBy(user) so trackers inherit the owner. Group with @Nested.
