### Infrastructure
- **MCP Protocol**: Full compliance with Model Context Protocol via @modelcontextprotocol/sdk
- **MCPB Bundle**: Conforms to MCPB specification v0.3 with complete manifest
- **Validation**: Zod schemas for all tool inputs with runtime type checking
- **Error Handling**: Consistent error responses with actionable messages
- **Security**: Input sanitization and parameter validation for all tools
- **Timeout Management**: 30-second timeout for CLI operations
- **Parameter Quoting**: Automatic quoting for filenames/values containing spaces
- **Logging**: stderr-only logging with sensitive data sanitization

### Technical Details
- **TypeScript**: Fully typed codebase with strict mode enabled
- **Node.js**: ES2022 module format with ESNext target
- **Transport**: stdio JSON-RPC for MCP communication
- **CLI Integration**: Wrapper for Obsidian CLI with proper parameter formatting
- **Bundle Format**: .mcpb packaging with manifest, icons, and compiled code

### Documentation
- Complete README with installation instructions for Claude Desktop extensions
- Manifest with detailed tool descriptions and parameter schemas
- Input validation and error documentation
- Development and testing guidelines

### Quality
- Zero TypeScript compilation errors
- MCPB manifest validation passes
- All tools tested with Obsidian CLI
- Comprehensive input schema definitions
- Security audit of parameter handling

## [1.1.2] - 2026-04-14

### Fixed
- **Ampersand in Filenames**: Fixed issue #2 where files with `&` in their names (e.g., "Research & Development.md") were causing search and file-not-found errors
  - Single ampersands are now preserved in filenames and paths
  - Security maintained: Dangerous `&&` command operators are still blocked by injection pattern detection
  - Also preserves parentheses `()`, brackets `[]`, and braces `{}` which are safe in quoted CLI arguments
  - Affects all file operations and search tools

## [1.1.1] - 2026-04-10

### Fixed
- **Quote Escaping**: Fixed critical bug where note content was being truncated when containing double quotes
  - Content like `"Bot QM"` is now properly escaped and passed to the CLI without truncation
  - Internal double quotes are escaped as `\"` before being wrapped in parameter quotes
  - Prevents shell from misinterpreting quote boundaries in parameter values
  - Affects all tools that pass content: create, append, prepend, search queries, etc.

## [1.1.0] - 2026-04-10

### Fixed
- **Square Brackets Preservation**: Fixed critical bug where square brackets `[` and `]` were being removed from note content during sanitization
  - Wikilinks (`[[link]]`) now work correctly when creating or modifying notes
  - Task checkboxes (`- [ ] Task` and `- [x] Done`) are properly preserved
  - Array notation and date formats with brackets are no longer corrupted
  - Security: Square brackets are safe because parameter values are quoted and passed as array arguments to the CLI
  - All dangerous shell metacharacters (`;`, `|`, `$()`, backticks, etc.) are still properly blocked

## [Unreleased]

### Planned
- Additional vault navigation tools (User Story 4 - deferred)
- Advanced features like templates and daily notes (User Story 5 - deferred)
- Performance optimizations for large vaults
- Expanded test coverage
- Multi-vault support enhancements
