The codebase follows Domain-Driven Design principles. + +### Layer Dependencies (Dependency Rule) +All dependencies point inward toward the domain: +- **Domain Layer** (innermost): Pure business logic, no external dependencies +- **Repository Layer**: Interfaces defining data access contracts +- **Use Case Layer**: Business orchestration, depends only on domain + repository interfaces +- **Infrastructure Layer**: Concrete implementations (filesystem, git, parsers) +- **Adapter Layer**: MCP protocol handlers, DTOs, external interface adapters + +### Key Domain Entities + +**Note**: Central entity representing an Obsidian note with: +- Path validation (must end in .md, no path traversal) +- Content with automatic extraction of WikiLinks and Tags +- Frontmatter (YAML metadata) +- Timestamps (created/modified) + +**Vault**: Aggregate root managing collections of notes with: +- Graph of note relationships +- Tag indexing with counts +- Statistics calculation + +**WikiLink**: Value object for `[[Internal Links]]` with support for: +- Aliases: `[[target|display text]]` +- Sections: `[[note#section]]` + +**Tag**: Value object for `#tags` with: +- Nested tag support: `#project/ai/research` +- Validation (no spaces, proper format) + +**Graph**: Thread-safe adjacency list for note relationships + +### Repository Pattern +All data access goes through interfaces in `internal/repository/`: +- **NoteRepository**: CRUD operations for notes +- **GitRepository**: Version control operations +- **VaultRepository**: Vault-level operations and statistics +- **SearchIndex**: Full-text search capabilities +- **GraphIndex**: Backlink/outlink indexing +- **TagIndex**: Tag-based search and operations + +### Configuration System +Uses `internal/config/config.go` with: +- YAML file configuration +- Environment variable overrides +- Validation with sensible defaults +- Support for vault path, git settings, caching, logging, performance tuning + +### Error Handling +Domain errors defined in `internal/domain/errors.go`: +- `ErrNoteNotFound`, `ErrNoteAlreadyExists` +- `ErrInvalidPath`, `ErrInvalidTag` +- `ErrCircularLink` + +### Key Architectural Patterns + +1. **Dependency Inversion**: Use cases depend on repository interfaces, not implementations +2. **Entity Encapsulation**: Domain entities manage their own business rules +3. **Value Objects**: Immutable types like WikiLink, Tag, Frontmatter +4. **Repository Pattern**: Clean separation between business logic and data access +5. **Configuration as Code**: Comprehensive config system with validation + +### Implementation Status +Currently implemented: +- ✅ Complete domain layer with all entities +- ✅ All repository interfaces +- ✅ Configuration system +- ✅ CLI entry point + +Still needed (per design.md roadmap): +- Infrastructure implementations (filesystem, git, markdown parsing) +- Use case implementations +- MCP adapter layer with 45+ tools +- Index implementations (search, graph, tag) + +### MCP Integration +When implementing MCP tools, they should: +- Live in `internal/adapter/mcp/tools/` +- Use DTOs from `internal/adapter/dto/` +- Call use cases, never repositories directly +- Handle MCP protocol specifics while keeping business logic in use cases \ No newline at end of file diff --git a/README.md b/README.md new file mode 100644
