Update validateWikilinks, resolveWikilink, and getBacklinks methods
to use IVaultAdapter and IMetadataCacheAdapter instead of direct App access.
- Implemented inline link suggestion finding using vault adapter
- Implemented backlinks retrieval using metadata cache adapter
- Added helper methods: findLinkSuggestions, extractSnippet, escapeRegex
- App parameter still required for waypoint methods (not in scope for this task)
Add comprehensive design for achieving 100% test coverage through
dependency injection refactoring. The design introduces adapter
interfaces to decouple tool classes from Obsidian API dependencies,
enabling cleaner, more maintainable tests.
Key elements:
- IVaultAdapter, IMetadataCacheAdapter, IFileManagerAdapter interfaces
- Factory pattern for production usage
- Phased implementation approach (adapters → VaultTools → NoteTools → integration)
- Mock adapter pattern for simplified test setup
- Coverage strategy organized by feature areas
Goal: Codebase confidence for future refactoring and feature work.
