ci: upgrade to Node.js 20 for native globalThis.crypto support

This commit resolves all required and optional issues from the plugin
submission review to comply with Obsidian plugin guidelines.

Required Changes:
- Type Safety: Added eslint-disable comments with justifications for
  necessary any types in JSON-RPC tool argument handling
- Command IDs: Removed redundant "mcp-server" prefix from command
  identifiers (BREAKING CHANGE):
  - start-mcp-server → start-server
  - stop-mcp-server → stop-server
  - restart-mcp-server → restart-server
- Promise Handling: Added void operator for intentional fire-and-forget
  promise in notification queue processing
- ESLint Directives: Added descriptive explanations to all
  eslint-disable comments
- Switch Statement Scope: Wrapped case blocks in braces to fix lexical
  declaration warnings in glob pattern matcher
- Regular Expression: Added eslint-disable comment for control character
  validation in Windows path checking
- Type Definitions: Changed empty object type {} to object in MCP
  capabilities interface
- Import Statements: Added comprehensive justifications for require()
  usage in Electron/Node.js modules (synchronous access required)

Optional Improvements:
- Code Cleanup: Removed unused imports (MCPPluginSettings, TFile,
  VaultInfo)

Documentation:
- Enhanced inline code documentation for ESLint suppressions and
  require() statements
- Added detailed rationale for synchronous module loading requirements
  in Obsidian plugin context
- Updated CHANGELOG.md for version 1.1.2

All changes verified:
- Build: Successful with no TypeScript errors
- Tests: All 760 tests passing
- ESLint: All review-required issues resolved

Version bumped to 1.1.2 in package.json and manifest.json

-# Agent Guidelines
-
-## Do
-
-- Add commands with stable IDs (don't rename once released)
-- Provide defaults and validation in settings
-- Write idempotent code paths so reload/unload doesn't leak listeners or intervals
-- Use `this.register*` helpers for everything that needs cleanup
-- Keep `main.ts` minimal and focused on lifecycle management
-- Split functionality across separate modules
-- Organize code into logical folders (commands/, ui/, utils/)
-
-## Don't
-
-- Introduce network calls without an obvious user-facing reason and documentation
-- Ship features that require cloud services without clear disclosure and explicit opt-in
-- Store or transmit vault contents unless essential and consented
-- Put all code in `main.ts` - delegate to separate modules
-- Create files larger than 200-300 lines without splitting them
-- Commit build artifacts to version control
-- Change plugin `id` after release
-- Rename command IDs after release

----
-
-# Coding Conventions
-
-## TypeScript Standards
-
-- Use TypeScript with `"strict": true` preferred
-- Bundle everything into `main.js` (no unbundled runtime deps)
-- Prefer `async/await` over promise chains
-- Handle errors gracefully
-
-## Code Organization
-
-- **Keep `main.ts` minimal** - Focus only on plugin lifecycle (onload, onunload, addCommand calls)
-- **Delegate all feature logic to separate modules**
-- **Split large files** - If any file exceeds ~200-300 lines, break it into smaller, focused modules
-- **Use clear module boundaries** - Each file should have a single, well-defined responsibility
-
-## Platform Compatibility
-
-- Avoid Node/Electron APIs if you want mobile compatibility
-- Set `isDesktopOnly` accordingly if using desktop-only features
-- Test on iOS and Android where feasible
-- Don't assume desktop-only behavior unless `isDesktopOnly` is `true`
-
-## Performance
-
-- Keep startup light - defer heavy work until needed
-- Avoid long-running tasks during `onload` - use lazy initialization
-- Batch disk access and avoid excessive vault scans
-- Debounce/throttle expensive operations in response to file system events
-- Avoid large in-memory structures on mobile - be mindful of memory and storage constraints

-
-# Commands & Settings
-
-## Commands
-
-- Add user-facing commands via `this.addCommand(...)`
-- **Use stable command IDs** - Don't rename once released
-- Ensure commands are unique and descriptive
-
-### Example: Add a Command
-
-```ts
-this.addCommand({
-  id: "your-command-id",
-  name: "Do the thing",
-  callback: () => this.doTheThing(),
-});
-```
-
-## Settings
-
-- Provide a settings tab if the plugin has configuration
-- Always provide sensible defaults
-- Persist settings using `this.loadData()` / `this.saveData()`
-- Provide defaults and validation in settings
-
-### Example: Persist Settings
-
-```ts
-interface MySettings { enabled: boolean }
-const DEFAULT_SETTINGS: MySettings = { enabled: true };
-
-async onload() {
-  this.settings = Object.assign({}, DEFAULT_SETTINGS, await this.loadData());
-  await this.saveData(this.settings);

-# Environment & Tooling
-
-## Required Tools
-
-- **Node.js**: Use current LTS (Node 18+ recommended)
-- **Package manager**: npm (required for this sample - `package.json` defines npm scripts and dependencies)
-- **Bundler**: esbuild (required for this sample - `esbuild.config.mjs` and build scripts depend on it)
-- **Types**: `obsidian` type definitions
-
-**Note**: This sample project has specific technical dependencies on npm and esbuild. If creating a plugin from scratch, you can choose different tools, but you'll need to replace the build configuration accordingly. Alternative bundlers like Rollup or webpack are acceptable if they bundle all external dependencies into `main.js`.
-
-## Common Commands
-
-### Install dependencies
-```bash
-npm install
-```
-
-### Development (watch mode)
-```bash
-npm run dev
-```
-
-### Production build
-```bash
-npm run build
-```
-
-## Linting
-
-- Install eslint: `npm install -g eslint`
-- Analyze project: `eslint main.ts`
-- Analyze folder: `eslint ./src/`

-# File & Folder Organization
-
-## Core Principles
-
-- **Organize code into multiple files**: Split functionality across separate modules rather than putting everything in `main.ts`
-- **Keep `main.ts` minimal**: Focus only on plugin lifecycle (onload, onunload, addCommand calls)
-- **Split large files**: If any file exceeds ~200-300 lines, break it into smaller, focused modules
-- **Use clear module boundaries**: Each file should have a single, well-defined responsibility

-## Recommended Structure
-
-```
-src/
-  main.ts           # Plugin entry point, lifecycle management only
-  settings.ts       # Settings interface and defaults
-  commands/         # Command implementations
-    command1.ts
-    command2.ts
-  ui/              # UI components, modals, views
-    modal.ts
-    view.ts
-  utils/           # Utility functions, helpers
-    helpers.ts
-    constants.ts
-  types.ts         # TypeScript interfaces and types
-```
-
-## Best Practices
-
-- Source lives in `src/`
-- Keep the plugin small - avoid large dependencies
-- Prefer browser-compatible packages
-- Generated output should be placed at the plugin root or `dist/` depending on build setup
-- Release artifacts must end up at the top level of the plugin folder (`main.js`, `manifest.json`, `styles.css`)

-# Manifest Rules
-
-## Required Fields
-
-The `manifest.json` must include:
-
-- `id` - Plugin ID; for local dev it should match the folder name
-- `name` - Display name
-- `version` - Semantic Versioning `x.y.z`
-- `minAppVersion` - Minimum Obsidian version required
-- `description` - Brief description
-- `isDesktopOnly` - Boolean indicating mobile compatibility
-
-## Optional Fields
-
-- `author` - Plugin author name
-- `authorUrl` - Author's URL
-- `fundingUrl` - Funding/donation URL (string or map)
-
-## Critical Rules
-
-- **Never change `id` after release** - Treat it as stable API
-- Keep `minAppVersion` accurate when using newer APIs
-- Use Semantic Versioning for `version` field

-- **Target**: Obsidian Community Plugin (TypeScript → bundled JavaScript)
-- **Entry point**: `main.ts` compiled to `main.js` and loaded by Obsidian
-- **Required release artifacts**: `main.js`, `manifest.json`, and optional `styles.css`
-
-## Key Requirements
-
-- All TypeScript code must be bundled into a single `main.js` file
-- Release artifacts must be placed at the top level of the plugin folder
-- Never commit build artifacts (`node_modules/`, `main.js`, etc.) to version control

-# Security, Privacy, and Compliance
-
-Follow Obsidian's **Developer Policies** and **Plugin Guidelines**.
-
-## Network & External Services
-
-- **Default to local/offline operation** - Only make network requests when essential to the feature
-- **No hidden telemetry** - If you collect optional analytics or call third-party services, require explicit opt-in and document clearly in `README.md` and in settings
-- **Never execute remote code** - Don't fetch and eval scripts, or auto-update plugin code outside of normal releases
-- **Clearly disclose external services** - Document any external services used, data sent, and risks
-
-## Data Access & Privacy
-
-- **Minimize scope** - Read/write only what's necessary inside the vault
-- **Do not access files outside the vault**
-- **Respect user privacy** - Do not collect vault contents, filenames, or personal information unless absolutely necessary and explicitly consented
-- **No deceptive patterns** - Avoid ads or spammy notifications
-
-## Resource Management
-
-- **Register and clean up all resources** - Use the provided `register*` helpers so the plugin unloads safely
-- Clean up DOM, app, and interval listeners properly

-description: Common issues and solutions
----
-
-# Troubleshooting
-
-## Plugin Doesn't Load After Build
-
-**Issue**: Plugin doesn't appear in Obsidian after building
-
-**Solution**: Ensure `main.js` and `manifest.json` are at the top level of the plugin folder under `<Vault>/.obsidian/plugins/<plugin-id>/`
-
-## Build Issues
-
-**Issue**: `main.js` is missing after build
-
-**Solution**: Run `npm run build` or `npm run dev` to compile your TypeScript source code
-
-## Commands Not Appearing
-
-**Issue**: Commands don't show up in command palette
-
-**Solution**: 
-- Verify `addCommand` runs after `onload`
-- Ensure command IDs are unique
-- Check that commands are properly registered
-
-## Settings Not Persisting
-
-**Issue**: Settings reset after reloading Obsidian
-
-**Solution**:
-- Ensure `loadData`/`saveData` are awaited
-- Re-render the UI after changes
-- Verify settings are properly merged with defaults
-
-## Mobile-Only Issues
-
-**Issue**: Plugin works on desktop but not mobile
-
-**Solution**:
-- Confirm you're not using desktop-only APIs
-- Check `isDesktopOnly` setting in manifest
-- Test on actual mobile devices or adjust compatibility

-# UX & Copy Guidelines
-
-For UI text, commands, and settings:
-
-## Text Formatting
-
-- **Prefer sentence case** for headings, buttons, and titles
-- Use clear, action-oriented imperatives in step-by-step copy
-- Keep in-app strings short, consistent, and free of jargon
-
-## UI References
-
-- Use **bold** to indicate literal UI labels
-- Prefer "select" for interactions
-- Use arrow notation for navigation: **Settings → Community plugins**
-
-## Examples
-
-✅ Good:
-- "Select **Settings → Community plugins**"
-- "Enable the plugin"
-- "Configure your API key"
-
-❌ Avoid:
-- "Go to Settings and then Community plugins"
-- "Turn on the plugin"
-- "Setup your API key"

-## Version Management
-
-- Bump `version` in `manifest.json` using Semantic Versioning (SemVer)
-- Update `versions.json` to map plugin version → minimum app version
-- Keep version numbers consistent across all release artifacts
-
-## Release Process
-
-1. **Create GitHub release** with tag that exactly matches `manifest.json`'s `version`
-   - **Do not use a leading `v`** in the tag
-2. **Attach required assets** to the release:
-   - `manifest.json`
-   - `main.js`
-   - `styles.css` (if present)
-3. After initial release, follow the process to add/update your plugin in the community catalog
-
-## Testing Before Release
-
-Manual install for testing:
-1. Copy `main.js`, `manifest.json`, `styles.css` (if any) to:
-   ```
-   <Vault>/.obsidian/plugins/<plugin-id>/
-   ```
-2. Reload Obsidian
-3. Enable the plugin in **Settings → Community plugins**

 ## Security Model
 
 - Server binds to `127.0.0.1` only (no external access)
-- Origin validation prevents DNS rebinding attacks
-- Optional Bearer token authentication via `enableAuth` + `apiKey` settings
-- CORS configurable via settings for local MCP clients
+- Host header validation prevents DNS rebinding attacks
+- CORS fixed to localhost-only origins (`http(s)://localhost:*`, `http(s)://127.0.0.1:*`)
+- **Mandatory authentication** via Bearer token (auto-generated on first install)
+- API keys encrypted using Electron's safeStorage API (system keychain: macOS Keychain, Windows Credential Manager, Linux Secret Service)
+- Encryption falls back to plaintext on systems without secure storage (e.g., Linux without keyring)
 
 ## Settings
 
 MCPPluginSettings (src/types/settings-types.ts):
 - `port`: HTTP server port (default: 3000)
 - `autoStart`: Start server on plugin load
-- `enableCORS`: Enable CORS middleware
-- `allowedOrigins`: Comma-separated origin whitelist
-- `enableAuth`: Require Bearer token
-- `apiKey`: Authentication token
+- `apiKey`: Required authentication token (encrypted at rest using Electron's safeStorage)
+- `enableAuth`: Always true (kept for backward compatibility during migration)
 - `notificationsEnabled`: Show tool call notifications in Obsidian UI
+- `showParameters`: Include parameters in notifications
 - `notificationDuration`: Auto-dismiss time for notifications
+- `logToConsole`: Log tool calls to console
+
+**Removed settings** (as of implementation plan 2025-10-25):
+- `enableCORS`: CORS is now always enabled with fixed localhost-only policy
+- `allowedOrigins`: Origin allowlist removed, only localhost origins allowed

+#### GitHub Release Workflow
+
+A GitHub Actions workflow automatically handles releases:
+
+**Location**: `.github/workflows/release.yml`
+
+**Trigger**: Push of semantic version tags (e.g., `1.2.3`)
+
+**Process**:
+1. Validates version consistency across `package.json`, `manifest.json`, and git tag
+2. Runs full test suite (blocks release if tests fail)
+3. Builds plugin with production config
+4. Creates draft GitHub release with `main.js`, `manifest.json`, and `styles.css`
+
+**Developer workflow**:
+```bash
+npm version patch  # or minor/major - updates manifest.json via version-bump.mjs
+git commit -m "chore: bump version to X.Y.Z"
+git tag X.Y.Z
+git push && git push --tags  # Triggers workflow
+```
+
+After workflow completes:
+1. Go to GitHub Releases
+2. Review draft release and attached files
+3. Write release notes
+4. Publish release
+
 ### Build Artifacts
 
 - **Never commit build artifacts** to version control (`main.js`, `node_modules/`, etc.)

+   ```
+
+4. **Start development build:**
+   ```bash
+   npm run dev
+   ```
+
+   This runs esbuild in watch mode, automatically rebuilding when you save changes.
+
+5. **Enable the plugin in Obsidian:**
+   - Open Obsidian Settings → Community Plugins
+   - Enable the plugin
+   - Reload Obsidian when prompted (Ctrl/Cmd + R in dev mode)
+
+## Development Workflow
+
+### Making Changes
+
+1. **Create a feature branch:**
+   ```bash
+   git checkout -b feature/your-feature-name
+   ```
+
+   Use descriptive branch names:
+   - `feature/add-tool-xyz` for new features
+   - `fix/issue-123` for bug fixes
+   - `docs/update-readme` for documentation
+   - `refactor/cleanup-utils` for refactoring
+
+2. **Make your changes:**
+   - Write code following the [Code Guidelines](#code-guidelines)
+   - Add tests for new functionality
+   - Update documentation as needed
+
+3. **Test your changes:**
+   ```bash
+   npm test                 # Run all tests
+   npm run test:watch      # Run tests in watch mode
+   npm run test:coverage   # Check coverage
+   ```
+
+4. **Build and test in Obsidian:**
+   ```bash
+   npm run build
+   ```
+
+   Then reload Obsidian (Ctrl/Cmd + R) to test your changes.
+
+5. **Commit your changes:**
+   ```bash
+   git add .
+   git commit -m "Add concise, descriptive commit message"
+   ```
+
+   See [Commit Message Guidelines](#commit-message-guidelines) below.
+
+### Commit Message Guidelines
+
+Write clear, concise commit messages that explain **why** the change was made, not just what changed:
+
+**Good examples:**
+- `fix: prevent race condition in concurrent note updates`
+- `feat: add support for Excalidraw compressed format`
+- `refactor: extract path validation into shared utility`
+- `docs: clarify API key security in README`
+- `test: add coverage for frontmatter edge cases`
+
+**Structure:**
+- Use imperative mood ("add" not "added" or "adds")
+- Keep the first line under 72 characters
+- Add a blank line followed by details if needed
+- Reference issue numbers when applicable: `fixes #123`
+
+**Type prefixes:**
+- `feat:` - New feature
+- `fix:` - Bug fix
+- `refactor:` - Code restructuring without behavior change
+- `test:` - Adding or updating tests
+- `docs:` - Documentation changes
+- `style:` - Formatting, no code change
+- `perf:` - Performance improvement
+- `chore:` - Maintenance tasks
+
+## Code Guidelines
+
+### Code Organization Best Practices
+
+- **Keep `main.ts` minimal** - Focus only on plugin lifecycle (onload, onunload, command registration)
+- **Delegate feature logic to separate modules** - All functionality lives in dedicated modules under `src/`
+- **Split large files** - If any file exceeds ~200-300 lines, break it into smaller, focused modules
+- **Use clear module boundaries** - Each file should have a single, well-defined responsibility
+
+### TypeScript Guidelines
+
+- **Use TypeScript strict mode** - The project uses `"strict": true`
+- **Provide explicit types** - Avoid `any`; use proper types or `unknown`
+- **Prefer interfaces over type aliases** for object shapes
+- **Use readonly** where appropriate to prevent mutations
+- **Export types** from `src/types/` for shared definitions
+
+### Style Guidelines
+
+- **Use sentence case** for UI strings, headings, and button text
+- **Use arrow notation** for navigation paths: "Settings → Community plugins"
+- **Prefer "select"** over "click" in documentation
+- **Use 4 spaces** for indentation (not tabs)
+- **Keep lines under 100 characters** where reasonable
+- **Use single quotes** for strings (unless templating)
+- **Add trailing commas** in multiline arrays/objects
+
+### Architecture Patterns
+
+- **Prefer async/await** over promise chains
+- **Handle errors gracefully** - Provide helpful error messages via ErrorMessages utility
+- **Use dependency injection** - Pass dependencies (vault, app) to constructors
+- **Avoid global state** - Encapsulate state within classes
+- **Keep functions small** - Each function should do one thing well
+
+### Performance Considerations
+
+- **Keep startup light** - Defer heavy work until needed; avoid long-running tasks during `onload`
+- **Batch disk access** - Avoid excessive vault scans
+- **Debounce/throttle expensive operations** - Especially for file system event handlers
+- **Cache when appropriate** - But invalidate caches correctly
+
+### Security Guidelines
+
+- **Default to local/offline operation** - This plugin binds to localhost only
+- **Never execute remote code** - Don't fetch and eval scripts
+- **Minimize scope** - Read/write only what's necessary inside the vault
+- **Do not access files outside the vault**
+- **Respect user privacy** - Don't collect vault contents without explicit consent
+- **Clean up resources** - Use `this.register*` helpers so the plugin unloads safely
+
+### Platform Compatibility
+
+This plugin is **desktop-only** (`isDesktopOnly: true`) because it uses Node.js HTTP server (Express). When extending functionality:
+- Avoid mobile-incompatible APIs
+- Don't assume desktop-only file system behavior
+- Consider graceful degradation where applicable
+
+## Testing Guidelines
+
+### Writing Tests
+
+- **Write tests for new features** - All new functionality should include tests
+- **Write tests for bug fixes** - Add a regression test that would have caught the bug
+- **Test edge cases** - Empty strings, null values, missing files, concurrent operations
+- **Use descriptive test names** - Explain what's being tested and expected behavior
+
+### Test Structure
+
+Tests are located in `tests/` and use Jest with ts-jest:
+
+```typescript
+describe('ToolName', () => {
+  describe('methodName', () => {
+    it('should do something specific', async () => {
+      // Arrange - Set up test data and mocks
+      const input = 'test-input';
+
+      // Act - Execute the code under test
+      const result = await someFunction(input);
+
+      // Assert - Verify the results
+      expect(result).toBe('expected-output');
+    });
+  });
+});
+```
+
+### Running Tests
+
+```bash
+npm test                 # Run all tests once
+npm run test:watch      # Watch mode for development
+npm run test:coverage   # Generate coverage report
+```
+
+### Mock Guidelines
+
+- Use the existing Obsidian API mocks in `tests/__mocks__/obsidian.ts`
+- Add new mocks when needed, keeping them minimal and focused
+- Reset mocks between tests to avoid test pollution
+

+- [ ] No build artifacts committed (`main.js`, `node_modules/`)
+- [ ] Branch is up to date with `master`
+
+## Release Process
+
+**Note:** Releases are managed by the maintainers. This section is for reference.
+
+### Versioning
+
+This project uses [Semantic Versioning](https://semver.org/):
+- **Major** (1.0.0): Breaking changes
+- **Minor** (0.1.0): New features, backward compatible
+- **Patch** (0.0.1): Bug fixes, backward compatible
+
+### Automated Release Workflow
+
+This project uses GitHub Actions to automate releases. The workflow is triggered when a semantic version tag is pushed.
+
+**Location:** `.github/workflows/release.yml`
+
+**Workflow process:**
+1. Validates version consistency across `package.json`, `manifest.json`, and git tag
+2. Runs full test suite (blocks release if tests fail)
+3. Builds plugin with production config (`npm run build`)
+4. Verifies build artifacts (`main.js`, `manifest.json`, `styles.css`)
+5. Creates draft GitHub release with artifacts attached
+
+### Release Steps for Maintainers
+
+1. **Update version numbers:**
+   ```bash
+   npm version [major|minor|patch]
+   ```
+
+   This automatically updates `package.json`, `manifest.json`, and `versions.json` via the `version-bump.mjs` script.
+
+2. **Update CHANGELOG.md** with release notes
+
+3. **Commit and tag:**
+   ```bash
+   git commit -m "chore: bump version to X.Y.Z"
+   git tag X.Y.Z
+   git push origin master --tags
+   ```
+
+   **Important:** Tags must match the format `X.Y.Z` (e.g., `1.2.3`) without a `v` prefix.
+
+4. **GitHub Actions creates draft release:**
+   - The workflow automatically builds and creates a draft release
+   - Wait for the workflow to complete (check Actions tab)
+
+5. **Publish the release:**
+   - Go to GitHub Releases
+   - Review the draft release
+   - Verify attached files (`main.js`, `manifest.json`, `styles.css`)
+   - Replace the placeholder release notes with actual notes from CHANGELOG
+   - Publish the release
+
+### Stability Guidelines
+
+- **Never change the plugin `id`** after release
+- **Never rename command IDs** after release - they are stable API
+- **Deprecate before removing** - Give users time to migrate
+- **Document breaking changes** clearly in CHANGELOG
+- **Tags must be semantic version format** - `X.Y.Z` without `v` prefix
+- **All versions must match** - `package.json`, `manifest.json`, and git tag must have identical versions
+
+## Getting Help
+
+If you need help or have questions:
+
+- **Documentation:** Check `CLAUDE.md` for detailed architecture information
+- **Issues:** Search existing issues or open a new one
+- **Discussions:** Start a discussion on GitHub for questions or ideas
+
+## Recognition
+
+Contributors will be acknowledged in release notes and the README. Thank you for helping improve this plugin!

+A plugin that makes your vault accessible via the [Model Context Protocol (MCP)](https://modelcontextprotocol.io) over HTTP. This allows AI assistants and other MCP clients to interact with your vault programmatically.
+
+**Version:** 1.0.0 | **Tested with:** Obsidian v1.9.14 | **License:** MIT
+
+> **⚠️ Security Notice**
+>
+> This plugin runs an HTTP server that exposes your vault's contents to MCP clients (like AI assistants). While the server is localhost-only with mandatory authentication, be aware that any client with your API key can read, create, modify, and delete files in your vault. Only share your API key with trusted applications.
 
 ## Features
 
 - **HTTP MCP Server**: Runs an HTTP server implementing the MCP protocol
 - **Vault Operations**: Exposes tools for reading, creating, updating, and deleting notes
 - **Search Functionality**: Search notes by content or filename
-- **Security**: Localhost-only binding, optional authentication, CORS configuration

+## Troubleshooting
+
+### Server won't start
+
+**Port already in use:**
+- Another application is using port 3000
+- Change the port in Settings → MCP Server → Port
+- Common alternatives: 3001, 8080, 8000
+
+**Permission denied:**
+- On Linux/macOS, ports below 1024 require root privileges
+- Use a port number above 1024 (default 3000 is fine)
+
+### Authentication failures
+
+**Invalid API key:**
+- Copy the API key again from Settings → MCP Server
+- Ensure you're including the full key with no extra spaces
+- Try regenerating the API key using the "Regenerate API Key" button
+
+**401 Unauthorized:**
+- Check that the `Authorization` header is properly formatted: `Bearer YOUR_API_KEY`
+- Verify there's a space between "Bearer" and the key
+
+### Connection issues
+
+**Cannot connect to server:**
+- Verify the server is running (check the ribbon icon or status in settings)
+- Ensure you're using `http://127.0.0.1:3000/mcp` (not `localhost` on some systems)
+- Check that no firewall is blocking local connections
+
+**CORS errors:**
+- The server only accepts requests from localhost origins
+- If using a web-based client, ensure it's running on `localhost` or `127.0.0.1`
+
+### General issues
+
+**Plugin not loading:**
+- Ensure you've enabled the plugin in Settings → Community Plugins
+- Try disabling and re-enabling the plugin
+- Check the Developer Console (Ctrl+Shift+I) for error messages
+
+**Changes not taking effect:**
+- Reload Obsidian (Ctrl/Cmd + R)
+- If building from source, ensure `npm run build` completed successfully
+
 ## Security Considerations
 
-- **Localhost Only**: The server binds to `127.0.0.1` to prevent external access
-- **Origin Validation**: Validates request origins to prevent DNS rebinding attacks
-- **Optional Authentication**: Use API keys to restrict access
+The plugin implements multiple security layers:
+
+- **Network binding**: Server binds to `127.0.0.1` only (no external access)
+- **Host header validation**: Prevents DNS rebinding attacks
+- **CORS policy**: Fixed localhost-only policy allows web-based clients on `localhost` or `127.0.0.1` (any port)
+- **Mandatory authentication**: All requests require Bearer token
+- **Encrypted storage**: API keys encrypted using system keychain when available
 - **Desktop Only**: This plugin only works on desktop (not mobile) due to HTTP server requirements

-```
-
-Should return:
-```json
-{"status":"ok","timestamp":1234567890}
-```
-
-### Check Localhost Binding
-
-The server only binds to `127.0.0.1` (localhost). You cannot connect from:
-- Other computers on the network
-- External IP addresses
-- Public internet
-
-This is by design for security.
-
-### Test MCP Endpoint
-
-```bash
-curl -X POST http://127.0.0.1:3000/mcp \
-  -H "Content-Type: application/json" \
-  -d '{"jsonrpc":"2.0","id":1,"method":"ping"}'
-```
-
-Should return:
-```json
-{"jsonrpc":"2.0","id":1,"result":{}}
-```
-
-## Authentication Issues
-
-### Wrong API Key
-
-**Error**: 401 Unauthorized
-
-**Solution**:
-- Check API key in settings matches what you're sending
-- Ensure format is: `Authorization: Bearer YOUR_API_KEY`
-- Try disabling authentication temporarily to test
-
-### CORS Errors
-
-**Error**: "CORS policy" in browser console
-
-**Solution**:
-1. Go to **Settings** → **MCP Server**
-2. Ensure "Enable CORS" is **ON**
-3. Check "Allowed Origins" includes your origin or `*`
-4. Restart server
-
-## Tools Not Working
-
-### Path Errors
-
-**Error**: "Note not found"
-
-**Solution**:
-- Use relative paths from vault root
-- Example: `folder/note.md` not `/full/path/to/note.md`
-- Don't include vault name in path
-
-### Permission Errors
-
-**Error**: "EACCES" or "Permission denied"
-
-**Solution**:
-- Check file permissions in vault
-- Ensure Obsidian has file system access
-- Check vault is not read-only
-
-### Search Returns Nothing
-
-**Issue**: `search_notes` returns no results
-
-**Solution**:
-- Check query is not empty
-- Search is case-insensitive
-- Searches both filename and content
-- Try simpler query
-

+# Version History
+
+## Public Release Version Strategy
+
+### Initial Public Release: 1.0.0 (2025-10-26)
+
+This plugin's first public release is marked as **version 1.0.0**.
+
+### Development History
+
+Prior to public release, the plugin went through private development with internal versions 1.0.0 through 3.0.0. These versions were used during development and testing but were never publicly released.
+
+When preparing for public release, the version was reset to 1.0.0 to clearly mark this as the first public version available to users.
+
+### Why Reset to 1.0.0?
+
+**Semantic Versioning**: Version 1.0.0 signals the first stable, public release of the plugin. It indicates:
+- The API is stable and ready for public use
+- All core features are implemented and tested
+- The plugin is production-ready
+
+**User Clarity**: Starting at 1.0.0 for the public release avoids confusion:
+- Users don't wonder "what happened to versions 1-2?"
+- Version number accurately reflects the public release history
+- Clear signal that this is the first version they can install
+
+**Git History Preserved**: The development history (95 commits) is preserved to:
+- Demonstrate development quality and security practices
+- Show comprehensive testing and iterative refinement
+- Provide context for future contributors
+- Maintain git blame and bisect capabilities
+
+### Version Numbering Going Forward
+
+From 1.0.0 onward, the plugin follows [Semantic Versioning](https://semver.org/):
+
+- **MAJOR** version (1.x.x): Incompatible API changes or breaking changes
+- **MINOR** version (x.1.x): New functionality in a backward-compatible manner
+- **PATCH** version (x.x.1): Backward-compatible bug fixes
+
+### Development Version Mapping
+
+For reference, here's what the private development versions contained:
+
+| Dev Version | Key Features Added |
+|-------------|-------------------|
+| 1.0.0 | Initial MCP server, basic CRUD tools |
+| 1.1.0 | Path normalization, error handling |
+| 1.2.0 | Enhanced authentication, parent folder detection |
+| 2.0.0 | API unification, typed results |
+| 2.1.0 | Discovery endpoints (stat, exists) |
+| 3.0.0 | Enhanced list operations |
+
+All these features are included in the public 1.0.0 release.
+
+### Commit History
+
+The git repository contains the complete development history showing the evolution from initial implementation through all features. This history demonstrates:
+
+- Security-conscious development (API key encryption, authentication)
+- Comprehensive test coverage (100% coverage goals)
+- Careful refactoring and improvements
+- Documentation and planning
+- Bug fixes and edge case handling
+
+No sensitive data exists in the git history (verified via audit).
+
+---
+
+## Future Versioning
+
+**Next versions** will be numbered according to the changes made:
+
+- **1.0.1**: Bug fixes and patches
+- **1.1.0**: New features (e.g., Resources API, Prompts API)
+- **2.0.0**: Breaking changes to tool schemas or behavior
+
+The CHANGELOG.md will document all public releases starting from 1.0.0.

-# 100% Test Coverage via Dependency Injection
-
-**Date:** 2025-10-19
-**Goal:** Achieve 100% test coverage through dependency injection refactoring
-**Current Coverage:** 90.58% overall (VaultTools: 71.72%, NoteTools: 92.77%)
-
-## Motivation
-
-We want codebase confidence for future refactoring and feature work. The current test suite has good coverage but gaps remain in:
-- Error handling paths
-- Edge cases (type coercion, missing data)
-- Complex conditional branches
-
-The current testing approach directly mocks Obsidian's `App` object, leading to:
-- Complex, brittle mock setups
-- Duplicated mocking code across test files
-- Difficulty isolating specific behaviors
-- Hard-to-test error conditions
-
-## Solution: Dependency Injection Architecture
-
-### Core Principle
-Extract interfaces for Obsidian API dependencies, allowing tools to depend on abstractions rather than concrete implementations. This enables clean, simple mocks in tests while maintaining production functionality.
-
-### Architecture Overview
-
-**Current State:**
-```typescript
-class NoteTools {
-  constructor(private app: App) {}
-  // Methods use: this.app.vault.X, this.app.metadataCache.Y, etc.
-}
-```
-
-**Target State:**
-```typescript
-class NoteTools {
-  constructor(
-    private vault: IVaultAdapter,
-    private metadata: IMetadataCacheAdapter,
-    private fileManager: IFileManagerAdapter
-  ) {}
-  // Methods use: this.vault.X, this.metadata.Y, etc.
-}
-
-// Production usage via factory:
-function createNoteTools(app: App): NoteTools {
-  return new NoteTools(
-    new VaultAdapter(app.vault),
-    new MetadataCacheAdapter(app.metadataCache),
-    new FileManagerAdapter(app.fileManager)
-  );
-}
-```
-
-## Interface Design
-
-### IVaultAdapter
-Wraps file system operations from Obsidian's Vault API.
-
-```typescript
-interface IVaultAdapter {
-  // File reading
-  read(path: string): Promise<string>;
-
-  // File existence and metadata
-  exists(path: string): boolean;
-  stat(path: string): { ctime: number; mtime: number; size: number } | null;
-
-  // File retrieval
-  getAbstractFileByPath(path: string): TAbstractFile | null;
-  getMarkdownFiles(): TFile[];
-
-  // Directory operations
-  getRoot(): TFolder;
-}
-```
-
-### IMetadataCacheAdapter
-Wraps metadata and link resolution from Obsidian's MetadataCache API.
-
-```typescript
-interface IMetadataCacheAdapter {
-  // Cache access
-  getFileCache(file: TFile): CachedMetadata | null;
-
-  // Link resolution
-  getFirstLinkpathDest(linkpath: string, sourcePath: string): TFile | null;
-
-  // Backlinks
-  getBacklinksForFile(file: TFile): { [key: string]: any };
-
-  // Additional metadata methods as needed
-}
-```
-
-### IFileManagerAdapter
-Wraps file modification operations from Obsidian's FileManager API.
-
-```typescript
-interface IFileManagerAdapter {
-  // File operations
-  rename(file: TAbstractFile, newPath: string): Promise<void>;
-  delete(file: TAbstractFile): Promise<void>;
-  create(path: string, content: string): Promise<TFile>;
-  modify(file: TFile, content: string): Promise<void>;
-}
-```
-
-## Implementation Strategy
-
-### Directory Structure
-```

-```
-
-### Migration Approach
-
-**Step 1: Create Adapters**
-- Define interfaces in `src/adapters/interfaces.ts`
-- Implement concrete adapters (simple pass-through wrappers initially)
-- Create mock adapter factories in `tests/__mocks__/adapters.ts`
-
-**Step 2: Refactor VaultTools**
-- Update constructor to accept adapter interfaces
-- Replace all `this.app.X` calls with `this.X` (using injected adapters)
-- Create `createVaultTools(app: App)` factory function
-- Update tests to use mock adapters
-
-**Step 3: Refactor NoteTools**
-- Same pattern as VaultTools
-- Create `createNoteTools(app: App)` factory function
-- Update tests to use mock adapters
-
-**Step 4: Integration**
-- Update ToolRegistry to use factory functions
-- Update main.ts to use factory functions
-- Verify all existing functionality preserved
-
-### Backward Compatibility
-
-**Plugin Code (main.ts, ToolRegistry):**
-- Uses factory functions: `createNoteTools(app)`, `createVaultTools(app)`
-- No awareness of adapters - just passes the App object
-- Public API unchanged
-
-**Tool Classes:**
-- Constructors accept adapters (new signature)
-- All methods work identically (internal implementation detail)
-- External callers use factory functions
-
-## Test Suite Overhaul
-
-### Mock Adapter Pattern
-
-**Centralized Mock Creation:**
-```typescript
-// tests/__mocks__/adapters.ts
-export function createMockVaultAdapter(overrides?: Partial<IVaultAdapter>): IVaultAdapter {
-  return {
-    read: jest.fn(),
-    exists: jest.fn(),
-    stat: jest.fn(),
-    getAbstractFileByPath: jest.fn(),
-    getMarkdownFiles: jest.fn(),
-    getRoot: jest.fn(),
-    ...overrides
-  };
-}
-
-export function createMockMetadataCacheAdapter(overrides?: Partial<IMetadataCacheAdapter>): IMetadataCacheAdapter {
-  return {
-    getFileCache: jest.fn(),
-    getFirstLinkpathDest: jest.fn(),
-    getBacklinksForFile: jest.fn(),
-    ...overrides
-  };
-}
-
-export function createMockFileManagerAdapter(overrides?: Partial<IFileManagerAdapter>): IFileManagerAdapter {
-  return {
-    rename: jest.fn(),
-    delete: jest.fn(),
-    create: jest.fn(),
-    modify: jest.fn(),
-    ...overrides
-  };
-}
-```
-
-**Test Setup Simplification:**
-```typescript
-// Before: Complex App mock with nested properties
-const mockApp = {
-  vault: { read: jest.fn(), ... },
-  metadataCache: { getFileCache: jest.fn(), ... },
-  fileManager: { ... },
-  // Many more properties...
-};
-
-// After: Simple, targeted mocks
-const vaultAdapter = createMockVaultAdapter({
-  read: jest.fn().mockResolvedValue('file content')
-});
-const tools = new VaultTools(vaultAdapter, mockMetadata, mockFileManager);
-```
-
-### Coverage Strategy by Feature Area
-
-**1. Frontmatter Operations**
-- Test string tags → array conversion
-- Test array tags → preserved as array
-- Test missing frontmatter → base metadata only
-- Test frontmatter parsing errors → error handling path
-- Test all field types (title, aliases, custom fields)
-
-**2. Wikilink Validation**
-- Test resolved links → included in results
-- Test unresolved links → included with error details
-- Test missing file → error path
-- Test heading links (`[[note#heading]]`)
-- Test alias links (`[[note|alias]]`)
-
-**3. Backlinks**
-- Test `includeSnippets: true` → snippets included
-- Test `includeSnippets: false` → snippets removed
-- Test `includeUnlinked: true` → unlinked mentions included
-- Test `includeUnlinked: false` → only linked mentions
-- Test error handling paths
-
-**4. Search Utilities**
-- Test glob pattern filtering
-- Test regex search with matches
-- Test regex search with no matches
-- Test invalid regex → error handling
-- Test edge cases (empty results, malformed patterns)
-
-**5. Note CRUD Operations**
-- Test all conflict strategies: error, overwrite, rename
-- Test version mismatch → conflict error
-- Test missing file on update → error path
-- Test permission errors → error handling
-- Test all edge cases in uncovered lines
-
-**6. Path Validation Edge Cases**
-- Test all PathUtils error conditions
-- Test leading/trailing slash handling
-- Test `..` traversal attempts
-- Test absolute path rejection
-
-## Implementation Phases
-
-### Phase 1: Foundation (Adapters)
-**Deliverables:**
-- `src/adapters/interfaces.ts` - All interface definitions
-- `src/adapters/vault-adapter.ts` - VaultAdapter implementation
-- `src/adapters/metadata-adapter.ts` - MetadataCacheAdapter implementation
-- `src/adapters/file-manager-adapter.ts` - FileManagerAdapter implementation

-  - Frontmatter extraction (lines 309-352)
-  - Wikilink validation error path (lines 716-735)
-  - Backlinks snippet removal (lines 824-852)
-  - Other uncovered paths
-
-**Success Criteria:**
-- VaultTools achieves 100% coverage (all metrics)

-- All 400+ tests passing
-- `npm run build` succeeds
-- Manual smoke test in Obsidian confirms functionality
-
-## Risk Mitigation
-
-**Risk: Breaking existing functionality**
-- Mitigation: Incremental refactoring, existing tests updated alongside code changes
-- Factory pattern keeps plugin code nearly unchanged
-
-**Risk: Incomplete interface coverage**
-- Mitigation: Start with methods actually used by tools, add to interfaces as needed
-- Adapters are simple pass-throughs, easy to extend
-
-**Risk: Complex migration**
-- Mitigation: Phased approach allows stopping after any phase
-- Git worktree isolates changes from main branch
-
-**Risk: Test maintenance burden**

-
-## Success Metrics
-
-**Coverage Goals:**
-- Statement coverage: 100%
-- Branch coverage: 100%
-- Function coverage: 100%
-- Line coverage: 100%
-
-**Quality Goals:**
-- All existing tests pass

-- Test code is cleaner and more maintainable
-
-**Timeline:**
-- Phase 1: ~2-3 hours (adapters + mocks)
-- Phase 2: ~3-4 hours (VaultTools refactor + tests)
-- Phase 3: ~2-3 hours (NoteTools refactor + tests)
-- Phase 4: ~1 hour (integration + verification)
-- Total: ~8-11 hours of focused work
-
-## Future Benefits
-
-**After this refactoring:**
-- Adding new tools is easier (use existing adapters)
-- Testing new features is trivial (mock only what you need)
-- Obsidian API changes isolated to adapter layer
-- Confidence in comprehensive test coverage enables fearless refactoring
-- New team members can understand test setup quickly

+# Cross-Environment Crypto Compatibility Design
+
+**Date:** 2025-10-26
+**Status:** Approved
+**Author:** Design session with user
+
+## Problem Statement
+
+The `generateApiKey()` function in `src/utils/auth-utils.ts` uses `crypto.getRandomValues()` which works in Electron/browser environments but fails in Node.js test environment with "ReferenceError: crypto is not defined". This causes test failures during CI/CD builds.
+
+## Goals
+
+1. Make code work cleanly in both browser/Electron and Node.js environments
+2. Use only built-in APIs (no additional npm dependencies)
+3. Maintain cryptographic security guarantees
+4. Keep production runtime behavior unchanged
+5. Enable tests to pass without mocking
+
+## Constraints
+
+- Must use only built-in APIs (no third-party packages)
+- Must maintain existing API surface of `generateApiKey()`
+- Must preserve cryptographic security in both environments
+- Must work with current Node.js version in project
+
+## Architecture
+
+### Component Overview
+
+The solution uses an abstraction layer pattern with environment detection:
+
+1. **crypto-adapter.ts** - New utility that provides unified crypto access
+2. **auth-utils.ts** - Modified to use the adapter
+3. **crypto-adapter.test.ts** - New test file for adapter verification
+
+### Design Decisions
+
+**Why abstraction layer over other approaches:**
+- **vs Runtime detection in auth-utils:** Separates concerns, makes crypto access reusable
+- **vs Jest polyfill:** Makes production code environment-aware instead of test-specific workarounds
+- **vs Dynamic require():** Cleaner than inline environment detection, easier to test
+
+**Why Web Crypto API standard:**
+- Node.js 15+ includes `crypto.webcrypto` implementing the same Web Crypto API as browsers
+- Allows using identical API (`getRandomValues()`) in both environments
+- Standards-based approach, future-proof
+
+## Implementation
+
+### File: `src/utils/crypto-adapter.ts` (new)
+
+```typescript
+/**
+ * Cross-environment crypto adapter
+ * Provides unified access to cryptographically secure random number generation
+ * Works in both browser/Electron (window.crypto) and Node.js (crypto.webcrypto)

+	}
+
+	return result;
+}
+
+// validateApiKey() remains unchanged
+```
+
+### File: `tests/crypto-adapter.test.ts` (new)
+
+Test coverage for the adapter:
+- Verify `getCryptoRandomValues()` returns filled array with correct length
+- Verify randomness (different calls produce different results)
+- Verify it works in Node.js test environment
+- Verify type preservation (Uint8Array in = Uint8Array out)
+
+## Error Handling
+
+### Scenarios Covered
+
+1. **Missing crypto API** - Throws descriptive error if neither environment has crypto
+2. **Node.js version incompatibility** - Error message guides developers to upgrade
+3. **Type safety** - TypeScript ensures correct typed array usage
+
+### Error Messages
+
+- "No Web Crypto API available in this environment" - Clear indication of what's missing
+
+## Testing Strategy
+
+### Existing Tests
+- `tests/main-migration.test.ts` - Will now pass without modification
+- Uses real Node.js `crypto.webcrypto` instead of mocks
+- No change to test assertions needed
+
+### New Tests
+- `tests/crypto-adapter.test.ts` - Verifies adapter functionality
+- Tests environment detection logic
+- Tests randomness properties
+- Tests type preservation
+
+### Coverage Impact
+- New file adds to overall coverage
+- No reduction in existing coverage
+- All code paths in adapter are testable
+
+## Production Behavior
+
+### Obsidian/Electron Environment
+- Always uses `window.crypto` (first check in getCrypto)
+- Zero change to existing runtime behavior
+- Same cryptographic guarantees as before
+
+### Node.js Test Environment
+- Uses `crypto.webcrypto` (Node.js 15+)
+- Provides identical Web Crypto API
+- Real cryptographic functions (not mocked)
+
+## Migration Path
+
+### Changes Required
+1. Create `src/utils/crypto-adapter.ts`
+2. Modify `src/utils/auth-utils.ts` to import and use adapter
+3. Create `tests/crypto-adapter.test.ts`
+4. Run tests to verify fix
+
+### Backward Compatibility
+- No breaking changes to public API
+- `generateApiKey()` signature unchanged
+- No settings or configuration changes needed
+
+### Rollback Plan
+- Single commit contains all changes
+- Can revert commit if issues found
+- Original implementation preserved in git history
+
+## Benefits
+
+1. **Clean separation of concerns** - Crypto access logic isolated
+2. **Standards-based** - Uses Web Crypto API in both environments
+3. **Reusable** - Other code can use crypto-adapter for crypto needs
+4. **Type-safe** - TypeScript ensures correct usage
+5. **Testable** - Each component can be tested independently
+6. **No mocking needed** - Tests use real crypto functions
+
+## Future Considerations
+
+- If other utilities need crypto, they can import crypto-adapter
+- Could extend adapter with other crypto operations (hashing, etc.)
+- Could add feature detection for specific crypto capabilities

+# Cross-Environment Crypto Compatibility Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Fix crypto API compatibility so tests pass in Node.js environment while maintaining production behavior in Electron.
+
+**Architecture:** Create crypto-adapter utility that detects environment and provides unified access to Web Crypto API (window.crypto in browser, crypto.webcrypto in Node.js).
+
+**Tech Stack:** TypeScript, Jest, Node.js crypto.webcrypto, Web Crypto API
+
+---
+
+## Task 1: Create crypto-adapter utility with tests (TDD)
+
+**Files:**
+- Create: `tests/crypto-adapter.test.ts`
+- Create: `src/utils/crypto-adapter.ts`
+
+**Step 1: Write the failing test**
+
+Create `tests/crypto-adapter.test.ts`:
+
+```typescript
+import { getCryptoRandomValues } from '../src/utils/crypto-adapter';
+
+describe('crypto-adapter', () => {
+	describe('getCryptoRandomValues', () => {
+		it('should fill Uint8Array with random values', () => {
+			const array = new Uint8Array(32);
+			const result = getCryptoRandomValues(array);
+
+			expect(result).toBe(array);
+			expect(result.length).toBe(32);
+			// Verify not all zeros (extremely unlikely with true random)
+			const hasNonZero = Array.from(result).some(val => val !== 0);
+			expect(hasNonZero).toBe(true);
+		});
+
+		it('should produce different values on subsequent calls', () => {
+			const array1 = new Uint8Array(32);
+			const array2 = new Uint8Array(32);
+
+			getCryptoRandomValues(array1);
+			getCryptoRandomValues(array2);
+
+			// Arrays should be different (extremely unlikely to be identical)
+			const identical = Array.from(array1).every((val, idx) => val === array2[idx]);
+			expect(identical).toBe(false);
+		});
+
+		it('should preserve array type', () => {
+			const uint8 = new Uint8Array(16);
+			const uint16 = new Uint16Array(8);
+			const uint32 = new Uint32Array(4);
+
+			const result8 = getCryptoRandomValues(uint8);
+			const result16 = getCryptoRandomValues(uint16);
+			const result32 = getCryptoRandomValues(uint32);
+
+			expect(result8).toBeInstanceOf(Uint8Array);
+			expect(result16).toBeInstanceOf(Uint16Array);
+			expect(result32).toBeInstanceOf(Uint32Array);
+		});
+
+		it('should work with different array lengths', () => {
+			const small = new Uint8Array(8);
+			const medium = new Uint8Array(32);
+			const large = new Uint8Array(128);
+
+			getCryptoRandomValues(small);
+			getCryptoRandomValues(medium);
+			getCryptoRandomValues(large);
+
+			expect(small.every(val => val >= 0 && val <= 255)).toBe(true);
+			expect(medium.every(val => val >= 0 && val <= 255)).toBe(true);
+			expect(large.every(val => val >= 0 && val <= 255)).toBe(true);
+		});
+	});
+});
+```
+
+**Step 2: Run test to verify it fails**
+
+Run: `npm test -- crypto-adapter.test.ts`
+
+Expected: FAIL with "Cannot find module '../src/utils/crypto-adapter'"
+
+**Step 3: Write minimal implementation**
+
+Create `src/utils/crypto-adapter.ts`:
+
+```typescript
+/**
+ * Cross-environment crypto adapter
+ * Provides unified access to cryptographically secure random number generation
+ * Works in both browser/Electron (window.crypto) and Node.js (crypto.webcrypto)
+ */
+
+/**
+ * Gets the appropriate Crypto interface for the current environment
+ * @returns Crypto interface with getRandomValues method
+ * @throws Error if no crypto API is available

+	if (typeof global !== 'undefined') {
+		const nodeCrypto = require('crypto');
+		if (nodeCrypto.webcrypto) {
+			return nodeCrypto.webcrypto;
+		}
+	}
+
+	throw new Error('No Web Crypto API available in this environment');
+}
+
+/**
+ * Fills a typed array with cryptographically secure random values
+ * @param array TypedArray to fill with random values
+ * @returns The same array filled with random values
+ */
+export function getCryptoRandomValues<T extends ArrayBufferView>(array: T): T {
+	return getCrypto().getRandomValues(array);
+}
+```
+
+**Step 4: Run test to verify it passes**
+
+Run: `npm test -- crypto-adapter.test.ts`
+
+Expected: PASS (all 4 tests passing)
+
+**Step 5: Commit**
+
+```bash
+git add tests/crypto-adapter.test.ts src/utils/crypto-adapter.ts
+git commit -m "feat: add cross-environment crypto adapter
+
+- Create getCryptoRandomValues() utility
+- Support both window.crypto (browser/Electron) and crypto.webcrypto (Node.js)
+- Add comprehensive test coverage for adapter functionality"
+```
+
+---
+
+## Task 2: Update auth-utils to use crypto-adapter
+
+**Files:**
+- Modify: `src/utils/auth-utils.ts:1-23`
+- Test: `tests/main-migration.test.ts` (existing tests should pass)
+
+**Step 1: Verify existing tests fail with current implementation**
+
+Run: `npm test -- main-migration.test.ts`
+
+Expected: FAIL with "ReferenceError: crypto is not defined"
+
+**Step 2: Update auth-utils.ts to use crypto-adapter**
+
+Modify `src/utils/auth-utils.ts`:
+
+```typescript
+/**
+ * Utility functions for authentication and API key management
+ */
+
+import { getCryptoRandomValues } from './crypto-adapter';
+
+/**
+ * Generates a cryptographically secure random API key
+ * @param length Length of the API key (default: 32 characters)

+	const values = new Uint8Array(length);
+
+	// Use cross-environment crypto adapter
+	getCryptoRandomValues(values);
+
+	let result = '';
+	for (let i = 0; i < length; i++) {
+		result += charset[values[i] % charset.length];
+	}
+
+	return result;
+}
+
+/**
+ * Validates API key strength
+ * @param apiKey The API key to validate
+ * @returns Object with isValid flag and optional error message
+ */
+export function validateApiKey(apiKey: string): { isValid: boolean; error?: string } {
+	if (!apiKey || apiKey.trim() === '') {
+		return { isValid: false, error: 'API key cannot be empty' };
+	}
+
+	if (apiKey.length < 16) {
+		return { isValid: false, error: 'API key must be at least 16 characters long' };
+	}
+
+	return { isValid: true };
+}
+```
+
+**Step 3: Run existing migration tests to verify they pass**
+
+Run: `npm test -- main-migration.test.ts`
+
+Expected: PASS (all tests in main-migration.test.ts passing)
+
+**Step 4: Run all tests to ensure no regressions**
+
+Run: `npm test`
+
+Expected: PASS (all 709+ tests passing, no failures)
+
+**Step 5: Commit**
+
+```bash
+git add src/utils/auth-utils.ts
+git commit -m "fix: use crypto-adapter in generateApiKey
+
+- Replace direct crypto.getRandomValues with getCryptoRandomValues
+- Fixes Node.js test environment compatibility
+- Maintains production behavior in Electron"
+```
+
+---
+
+## Task 3: Verify fix and run full test suite
+
+**Files:**
+- None (verification only)
+
+**Step 1: Run full test suite**
+
+Run: `npm test`
+
+Expected: All tests pass (should be 713 tests: 709 existing + 4 new crypto-adapter tests)
+
+**Step 2: Verify test coverage meets thresholds**
+
+Run: `npm run test:coverage`
+
+Expected:
+- Lines: ≥97%
+- Statements: ≥97%
+- Branches: ≥92%
+- Functions: ≥96%
+
+Coverage should include new crypto-adapter.ts file.
+
+**Step 3: Run type checking**
+
+Run: `npm run build`
+
+Expected: No TypeScript errors, build completes successfully
+
+**Step 4: Document verification in commit message if needed**
+
+If all checks pass, the implementation is complete. No additional commit needed unless documentation updates are required.
+
+---
+
+## Completion Checklist
+
+- [ ] crypto-adapter.ts created with full test coverage
+- [ ] auth-utils.ts updated to use crypto-adapter
+- [ ] All existing tests pass (main-migration.test.ts)
+- [ ] New crypto-adapter tests pass (4 tests)
+- [ ] Full test suite passes (713 tests)
+- [ ] Coverage thresholds met
+- [ ] TypeScript build succeeds
+- [ ] Two commits created with descriptive messages
+
+## Expected Outcome
+
+After completing all tasks:
+1. Tests run successfully in Node.js environment (no crypto errors)
+2. Production code unchanged in behavior (still uses window.crypto in Electron)
+3. Clean abstraction for future crypto operations
+4. Full test coverage maintained
+5. Ready for code review and PR creation
+
+## Notes for Engineer
+
+- **Environment detection:** The adapter checks `typeof window` first (browser/Electron), then `typeof global` (Node.js)
+- **Web Crypto API standard:** Both environments use the same API (getRandomValues), just accessed differently
+- **Node.js requirement:** Requires Node.js 15+ for crypto.webcrypto support
+- **Type safety:** TypeScript generic `<T extends ArrayBufferView>` preserves array type through the call
+- **No mocking needed:** Tests use real crypto functions in Node.js via crypto.webcrypto

+# ObsidianReviewBot Fixes Design
+
+**Date:** 2025-10-28
+**Status:** Approved
+**PR:** https://github.com/obsidianmd/obsidian-releases/pull/8298
+
+## Overview
+
+This design addresses all required issues identified by ObsidianReviewBot for the MCP Server plugin submission to the Obsidian community plugin repository.
+
+## Required Fixes
+
+1. **Config path documentation** - Update hardcoded `.obsidian` examples to generic alternatives
+2. **Command naming** - Remove "MCP Server" from command display names
+3. **File deletion API** - Replace `vault.delete()` with `app.fileManager.trashFile()`
+4. **Inline styles** - Extract 90+ JavaScript style assignments to CSS with semantic class names
+
+## Implementation Strategy
+
+**Approach:** Fix-by-fix across files - Complete one type of fix across all affected files before moving to the next fix type.
+
+**Benefits:**
+- Groups related changes together for clearer git history
+- Easier to test each fix type independently
+- Simpler code review with focused commits
+
+## Fix Order and Details
+
+### Fix 1: Config Path Documentation
+
+**Files affected:** `src/tools/index.ts`
+
+**Changes:**
+- Line 235: Update exclude pattern example from `['.obsidian/**', '*.tmp']` to `['templates/**', '*.tmp']`
+- Line 300: Same update for consistency
+
+**Rationale:** Obsidian's configuration directory isn't necessarily `.obsidian` - users can configure this. Examples should use generic folders rather than system directories.
+
+**Risk:** None - documentation only, no functional changes
+
+### Fix 2: Command Naming
+
+**Files affected:** `src/main.ts`
+
+**Changes:**
+- Line 54: "Start MCP Server" → "Start server"
+- Line 62: "Stop MCP Server" → "Stop server"
+- Line 70: "Restart MCP Server" → "Restart server"
+
+**Note:** Command IDs remain unchanged (stable API requirement)
+
+**Rationale:** Obsidian plugin guidelines state command names should not include the plugin name itself.
+
+**Risk:** Low - purely cosmetic change to command palette display
+
+### Fix 3: File Deletion API
+
+**Files affected:** `src/tools/note-tools.ts`
+
+**Changes:**
+- Line 162: `await this.vault.delete(existingFile)` → `await this.fileManager.trashFile(existingFile)`
+- Line 546: `await this.vault.delete(file)` → `await this.fileManager.trashFile(file)`
+
+**Context:**
+- Line 162: Overwrite conflict resolution when creating files
+- Line 546: Permanent delete operation (when soft=false)
+
+**Rationale:** Use `app.fileManager.trashFile()` instead of direct deletion to respect user's trash preferences configured in Obsidian settings.
+
+**Risk:** Medium - changes deletion behavior, requires testing both scenarios
+
+**Testing:**
+- Verify overwrite conflict resolution still works
+- Verify permanent delete operation respects user preferences
+- Confirm files go to user's configured trash location
+
+### Fix 4: Inline Styles to CSS
+
+**Files affected:**
+- `styles.css` (add new classes)
+- `src/settings.ts` (remove inline styles, add CSS classes)
+
+**New CSS Classes:**
+
+```css
+/* Authentication section */
+.mcp-auth-section { margin-bottom: 20px; }
+.mcp-auth-summary {
+  font-size: 1.17em;
+  font-weight: bold;
+  margin-bottom: 12px;
+  cursor: pointer;
+}
+
+/* API key display */
+.mcp-key-display {
+  padding: 12px;
+  background-color: var(--background-secondary);
+  border-radius: 4px;
+  font-family: monospace;
+  font-size: 0.9em;
+  word-break: break-all;
+  user-select: all;
+  cursor: text;
+  margin-bottom: 16px;
+}
+
+/* Tab navigation */
+.mcp-config-tabs {
+  display: flex;
+  gap: 8px;
+  margin-bottom: 16px;
+  border-bottom: 1px solid var(--background-modifier-border);
+}
+
+.mcp-tab {
+  padding: 8px 16px;
+  border: none;
+  background: none;
+  cursor: pointer;
+  border-bottom: 2px solid transparent;
+}
+
+.mcp-tab-active {
+  border-bottom-color: var(--interactive-accent);
+  font-weight: bold;
+}
+
+/* Config display */
+.mcp-config-display {
+  padding: 12px;
+  background-color: var(--background-secondary);
+  border-radius: 4px;
+  font-size: 0.85em;
+  overflow-x: auto;
+  user-select: text;
+  cursor: text;
+  margin-bottom: 12px;
+}
+
+/* Helper text */
+.mcp-file-path {
+  padding: 8px;
+  background-color: var(--background-secondary);
+  border-radius: 4px;
+  font-family: monospace;
+  font-size: 0.9em;
+  margin-bottom: 12px;
+  color: var(--text-muted);
+}
+
+.mcp-usage-note {
+  font-size: 0.9em;
+  color: var(--text-muted);
+  font-style: italic;
+}
+
+/* Additional utility classes */
+.mcp-heading {
+  margin-top: 24px;
+  margin-bottom: 12px;
+}
+
+.mcp-container { margin-bottom: 20px; }
+
+.mcp-button-group {
+  display: flex;
+  gap: 8px;
+  margin-bottom: 12px;
+}
+
+.mcp-label {
+  margin-bottom: 4px;
+  font-size: 0.9em;
+  color: var(--text-muted);
+}
+```
+
+**Changes to settings.ts:**
+- Remove all `.style.` property assignments (90+ lines)
+- Add corresponding CSS class names using `.addClass()` or `className` property
+- Preserve dynamic styling for tab active state (use conditional class application)
+
+**Rationale:** Obsidian plugin guidelines require styles to be in CSS files rather than applied via JavaScript. This improves maintainability and follows platform conventions.
+
+**Risk:** High - largest refactor, visual regression possible
+
+**Testing:**
+- Build and load in Obsidian
+- Verify settings panel appearance unchanged in both light and dark themes
+- Test all interactive elements: collapsible sections, tabs, buttons
+- Confirm responsive behavior
+
+## Testing Strategy
+
+**After each fix:**
+1. Run `npm test` - ensure no test failures
+2. Run `npm run build` - verify TypeScript compilation
+3. Check for linting issues
+
+**Before final commit:**
+1. Full test suite passes
+2. Clean build with no warnings
+3. Manual smoke test of all settings UI features
+4. Visual verification in both light and dark themes
+
+## Success Criteria
+
+- All 4 ObsidianReviewBot required issues resolved
+- No test regressions
+- No visual regressions in settings panel
+- Clean build with no TypeScript errors
+- Ready for PR re-submission

+**Step 5: Run specific note-tools tests**
+
+Run: `npm test -- tests/note-tools.test.ts`
+Expected: All note-tools tests pass, including:
+- createNote with onConflict='overwrite'
+- deleteNote with soft=false
+
+**Step 6: Commit**
+
+```bash
+git add src/tools/note-tools.ts
+git commit -m "fix: use fileManager.trashFile instead of vault.delete
+
+- Replace vault.delete() with app.fileManager.trashFile()
+- Respects user's trash preferences in Obsidian settings
+- Applies to both overwrite conflicts and permanent deletes
+- Addresses ObsidianReviewBot feedback"
+```

+## Task 4: Extract Inline Styles to CSS
+
+**Files:**
+- Modify: `styles.css` (add new classes)
+- Modify: `src/settings.ts` (remove inline styles, add CSS classes)
+
+**Step 1: Add CSS classes to styles.css**
+
+Append the following CSS classes to `styles.css`:
+
+```css
+/* MCP Settings Panel Styles */
+
+/* Authentication section */
+.mcp-auth-section {
+	margin-bottom: 20px;
+}
+
+.mcp-auth-summary {
+	font-size: 1.17em;
+	font-weight: bold;
+	margin-bottom: 12px;
+	cursor: pointer;
+}
+
+/* API key display */
+.mcp-api-key-container {
+	margin-bottom: 20px;
+	margin-left: 0;
+}
+
+.mcp-button-group {
+	display: flex;
+	gap: 8px;
+	margin-bottom: 12px;
+}
+
+.mcp-key-display {
+	padding: 12px;
+	background-color: var(--background-secondary);
+	border-radius: 4px;
+	font-family: monospace;
+	font-size: 0.9em;
+	word-break: break-all;
+	user-select: all;
+	cursor: text;
+	margin-bottom: 16px;
+}
+
+/* Headings and containers */
+.mcp-heading {
+	margin-top: 24px;
+	margin-bottom: 12px;
+}
+
+.mcp-container {
+	margin-bottom: 20px;
+}
+
+/* Tab navigation */
+.mcp-tab-container {
+	display: flex;
+	gap: 8px;
+	margin-bottom: 16px;
+	border-bottom: 1px solid var(--background-modifier-border);
+}
+
+.mcp-tab {
+	padding: 8px 16px;
+	border: none;
+	background: none;
+	cursor: pointer;
+	border-bottom: 2px solid transparent;
+	font-weight: normal;
+}
+
+.mcp-tab-active {
+	border-bottom-color: var(--interactive-accent);
+	font-weight: bold;
+}
+
+/* Tab content */
+.mcp-tab-content {
+	margin-top: 16px;
+}
+
+/* Labels and helper text */
+.mcp-label {
+	margin-bottom: 4px;
+	font-size: 0.9em;
+	color: var(--text-muted);
+}
+
+.mcp-file-path {
+	padding: 8px;
+	background-color: var(--background-secondary);
+	border-radius: 4px;
+	font-family: monospace;
+	font-size: 0.9em;
+	margin-bottom: 12px;
+	color: var(--text-muted);
+}
+
+.mcp-usage-note {
+	font-size: 0.9em;
+	color: var(--text-muted);
+	font-style: italic;
+}
+
+/* Config display */
+.mcp-config-display {
+	padding: 12px;
+	background-color: var(--background-secondary);
+	border-radius: 4px;
+	font-size: 0.85em;
+	overflow-x: auto;
+	user-select: text;
+	cursor: text;
+	margin-bottom: 12px;
+}
+
+/* Copy button spacing */
+.mcp-copy-button {
+	margin-bottom: 12px;
+}
+
+/* Notification section */
+.mcp-notif-section {
+	margin-bottom: 20px;
+}
+
+.mcp-notif-summary {
+	font-size: 1.17em;
+	font-weight: bold;
+	margin-bottom: 12px;
+	cursor: pointer;
+}
+```
+
+**Step 2: Update authentication section in settings.ts (lines 199-205)**
+
+In `src/settings.ts`, find the `displayAuthenticationDetails` method around line 199 and replace inline styles:
+
+```typescript
+const authDetails = containerEl.createEl('details', { cls: 'mcp-auth-section' });
+authDetails.open = true;
+const authSummary = authDetails.createEl('summary', {
+	text: 'Authentication',
+	cls: 'mcp-auth-summary'
+});
+```
+
+**Step 3: Update API key container styles (lines 217-224)**
+
+Replace:
+```typescript
+const apiKeyContainer = containerEl.createDiv({ cls: 'mcp-api-key-container' });
+const apiKeyButtonContainer = apiKeyContainer.createDiv({ cls: 'mcp-button-group' });
+```
+
+**Step 4: Update key display container styles (lines 247-255)**
+
+Replace:
+```typescript
+const keyDisplayContainer = apiKeyContainer.createDiv({
+	text: apiKey,
+	cls: 'mcp-key-display'
+});
+```
+
+**Step 5: Update config section headings (lines 260-264)**
+
+Replace:
+```typescript
+const configHeading = containerEl.createEl('h3', {
+	text: 'Connection Configuration',
+	cls: 'mcp-heading'
+});
+const configContainer = containerEl.createDiv({ cls: 'mcp-container' });
+```
+
+**Step 6: Update tab container styles (lines 271-285)**
+
+Replace the tab container creation:
+```typescript
+const tabContainer = configContainer.createDiv({ cls: 'mcp-tab-container' });
+
+const windsurfTab = tabContainer.createEl('button', {
+	text: 'Windsurf',
+	cls: this.activeConfigTab === 'windsurf' ? 'mcp-tab mcp-tab-active' : 'mcp-tab'
+});
+
+const claudeCodeTab = tabContainer.createEl('button', {
+	text: 'Claude Code',
+	cls: this.activeConfigTab === 'claude-code' ? 'mcp-tab mcp-tab-active' : 'mcp-tab'
+});
+```
+
+**Step 7: Update tab content and labels (lines 311-327)**
+
+Replace:
+```typescript
+const tabContent = configContainer.createDiv({ cls: 'mcp-tab-content' });
+
+const fileLocationLabel = tabContent.createDiv({
+	text: 'Configuration file location:',
+	cls: 'mcp-label'
+});
+
+const filePathDisplay = tabContent.createDiv({
+	text: filePath,
+	cls: 'mcp-file-path'
+});
+
+const copyConfigButton = tabContent.createEl('button', {
+	text: 'Copy to Clipboard',
+	cls: 'mcp-copy-button'
+});
+```
+
+**Step 8: Update config display (lines 339-346)**
+
+Replace:
+```typescript
+const configDisplay = tabContent.createEl('pre', { cls: 'mcp-config-display' });
+
+const usageNoteDisplay = tabContent.createDiv({
+	text: usageNote,
+	cls: 'mcp-usage-note'
+});
+```
+
+**Step 9: Update notification section (lines 357-362)**
+
+Replace:
+```typescript
+const notifDetails = containerEl.createEl('details', { cls: 'mcp-notif-section' });
+notifDetails.open = false;
+const notifSummary = notifDetails.createEl('summary', {
+	text: 'Notification Settings',
+	cls: 'mcp-notif-summary'
+});
+```
+
+**Step 10: Update updateConfigTabDisplay method (lines 439-521)**
+
+Find the `updateConfigTabDisplay` method and update the tab button styling to use CSS classes with conditional application:
+
+```typescript
+private updateConfigTabDisplay(containerEl: HTMLElement) {
+	// ... existing code ...
+
+	const tabContainer = containerEl.createDiv({ cls: 'mcp-tab-container' });
+
+	const windsurfTab = tabContainer.createEl('button', {
+		text: 'Windsurf',
+		cls: this.activeConfigTab === 'windsurf' ? 'mcp-tab mcp-tab-active' : 'mcp-tab'
+	});
+
+	const claudeCodeTab = tabContainer.createEl('button', {
+		text: 'Claude Code',
+		cls: this.activeConfigTab === 'claude-code' ? 'mcp-tab mcp-tab-active' : 'mcp-tab'
+	});
+
+	// Update tab content with CSS classes
+	const tabContent = containerEl.createDiv({ cls: 'mcp-tab-content' });
+
+	const fileLocationLabel = tabContent.createDiv({
+		text: 'Configuration file location:',
+		cls: 'mcp-label'
+	});
+
+	const filePathDisplay = tabContent.createDiv({
+		text: filePath,
+		cls: 'mcp-file-path'
+	});
+
+	const copyConfigButton = tabContent.createEl('button', {
+		text: 'Copy to Clipboard',
+		cls: 'mcp-copy-button'
+	});
+
+	const configDisplay = tabContent.createEl('pre', { cls: 'mcp-config-display' });
+
+	const usageNoteDisplay = tabContent.createDiv({
+		text: usageNote,
+		cls: 'mcp-usage-note'
+	});
+}
+```
+
+**Step 11: Verify all inline styles removed**
+
+Run: `grep -n "\.style\." src/settings.ts`
+Expected: No matches (or only legitimate dynamic styling that can't be in CSS)
+
+**Step 12: Build and verify**
+
+Run: `npm run build`
+Expected: Clean build with no TypeScript errors
+
+**Step 13: Run tests**
+
+Run: `npm test`
+Expected: All 716 tests pass
+
+**Step 14: Commit**
+
+```bash
+git add styles.css src/settings.ts
+git commit -m "fix: extract inline styles to CSS with semantic classes
+
+- Add mcp-* prefixed CSS classes for all settings UI elements
+- Remove 90+ inline style assignments from settings.ts

+# Obsidian Plugin Submission Fixes Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Fix all code quality issues identified in the Obsidian plugin submission review to meet community plugin standards.
+
+**Architecture:** Systematic refactoring across the codebase to replace `any` types with proper TypeScript types, remove `console.log` statements, fix command IDs, improve promise handling, use proper UI APIs, convert require() to ES6 imports, and standardize text formatting.
+
+**Tech Stack:** TypeScript, Obsidian API, Express, Node.js
+
+---
+
+## Task 1: Fix Type Safety Issues - Replace `any` Types
+
+**Files:**
+- Modify: `src/main.ts:27`
+- Modify: `src/utils/encryption-utils.ts:2`
+- Modify: `src/types/mcp-types.ts` (multiple locations)
+- Modify: `src/tools/index.ts` (multiple locations)
+- Modify: `src/tools/note-tools.ts` (multiple locations)
+- Modify: `src/tools/vault-tools.ts` (multiple locations)
+- Modify: `src/utils/frontmatter-utils.ts` (multiple locations)
+- Modify: `src/ui/notifications.ts` (multiple locations)
+- Modify: `src/server/middleware.ts` (multiple locations)
+- Modify: `src/adapters/file-manager-adapter.ts` (multiple locations)
+- Modify: `src/adapters/interfaces.ts` (multiple locations)
+- Modify: `src/utils/glob-utils.ts` (multiple locations)
+- Modify: `src/server/mcp-server.ts` (multiple locations)
+- Modify: `src/server/routes.ts` (multiple locations)
+
+**Step 1: Define proper types for Electron safeStorage**
+
+In `src/utils/encryption-utils.ts`, replace the `any` type with a proper interface:
+
+```typescript
+// Define Electron SafeStorage interface
+interface ElectronSafeStorage {
+	isEncryptionAvailable(): boolean;
+	encryptString(plainText: string): Buffer;
+	decryptString(encrypted: Buffer): string;
+}
+
+let safeStorage: ElectronSafeStorage | null = null;
+```
+
+**Step 2: Fix legacy settings migration in main.ts**
+
+In `src/main.ts:27`, replace:
+
+```typescript
+const legacySettings = this.settings as any;
+```
+
+with:
+
+```typescript
+interface LegacySettings extends MCPPluginSettings {
+	enableCORS?: boolean;
+	allowedOrigins?: string[];
+}
+const legacySettings = this.settings as LegacySettings;
+```
+
+**Step 3: Review and fix types in mcp-types.ts**
+
+Read `src/types/mcp-types.ts` and replace all `any` types with proper JSON-RPC and MCP protocol types:
+- Define proper JSONValue type
+- Define proper JSONRPCRequest interface
+- Define proper JSONRPCResponse interface
+- Define proper CallToolResult content types
+
+**Step 4: Fix tool registry types in tools/index.ts**
+
+Replace `any` types with proper tool definition types and CallToolResult types.
+
+**Step 5: Fix note-tools.ts and vault-tools.ts types**
+
+Replace `any` types with proper TFile, TFolder, MetadataCache types from Obsidian API.
+
+**Step 6: Fix frontmatter-utils.ts types**
+
+Replace `any` types with proper YAML value types (string | number | boolean | null | object).
+
+**Step 7: Commit type safety fixes**
+
+```bash
+git add src/
+git commit -m "fix: replace any types with proper TypeScript types"
+```
+
+---
+
+## Task 2: Remove Forbidden console.log Statements
+
+**Files:**
+- Modify: `src/main.ts:21,29`
+- Modify: `src/ui/notifications.ts:94`
+- Modify: `src/server/mcp-server.ts:103,127`
+
+**Step 1: Remove console.log from main.ts**
+
+In `src/main.ts`, remove lines 21 and 29 (API key generation and migration logs). These are informational logs that don't need to be shown to users.
+
+**Step 2: Remove console.log from notifications.ts**
+
+In `src/ui/notifications.ts:94`, the log is controlled by `logToConsole` setting. Keep the functionality but use `console.debug` instead:
+
+```typescript
+if (this.settings.logToConsole) {
+	console.debug(`[MCP] Tool call: ${toolName}`, args);
+}
+```
+
+**Step 3: Remove console.log from mcp-server.ts**
+
+In `src/server/mcp-server.ts:103,127`, remove the server start/stop logs. The UI already shows this status via Notice and status bar.
+
+**Step 4: Verify all console methods are allowed**
+
+Run grep to verify only `warn`, `error`, and `debug` remain:
+
+```bash
+grep -r "console\." src/ | grep -v "console.warn\|console.error\|console.debug" | grep -v "node_modules"
+```
+
+**Step 5: Commit console.log removal**
+
+```bash
+git add src/
+git commit -m "fix: remove console.log statements, use console.debug where needed"
+```
+
+---
+
+## Task 3: Fix Command ID Naming
+
+**Files:**
+- Read: `src/main.ts:52-83` (to identify command IDs)
+- Modify: `manifest.json` (if command IDs are documented there)
+
+**Step 1: Review current command IDs**
+
+Current command IDs in `src/main.ts`:
+- `start-mcp-server` ✓ (correct)
+- `stop-mcp-server` ✓ (correct)
+- `restart-mcp-server` ✓ (correct)
+- `view-notification-history` ✓ (correct)
+
+**Note:** The review mentioned "Three command IDs incorrectly include the plugin name prefix". After reviewing the code, the command IDs do NOT include "mcp-server:" prefix - they use simple kebab-case IDs which is correct. The command NAMES (user-facing text) are also correct and don't include the plugin name.
+
+**Step 2: Verify no issues**
+
+The command IDs are already correct. No changes needed for this task.
+
+**Step 3: Document verification**
+
+```bash
+echo "Command IDs verified - no changes needed" > /tmp/command-id-check.txt
+```
+
+---
+
+## Task 4: Fix Promise Handling Issues
+
+**Files:**
+- Modify: `src/main.ts:16` (onload return type)
+- Modify: `src/tools/note-tools.ts` (async methods without await)
+- Modify: `src/adapters/vault-adapter.ts` (async methods without await)
+- Modify: `src/adapters/file-manager-adapter.ts` (async methods without await)
+- Modify: `src/ui/notifications.ts` (async methods without await)
+- Modify: `src/server/mcp-server.ts` (async methods without await)
+
+**Step 1: Fix onload return type**
+
+In `src/main.ts:16`, the `onload()` method is async but Plugin.onload expects void. This is actually fine - Obsidian's Plugin class allows async onload. Verify this is not a false positive by checking if there are any actual issues.
+
+**Step 2: Review async methods without await**
+
+Search for async methods that don't use await and may not need to be async:
+
+```bash
+grep -A 20 "async " src/**/*.ts | grep -v "await"
+```
+
+**Step 3: Fix methods that return Promise in void context**
+
+Look for callback functions that are async but used where void is expected:
+- Button click handlers
+- Event listeners
+- Command callbacks
+
+Wrap these with void operators or handle promises properly:
+
+```typescript
+// Before:
+.onClick(async () => {
+	await this.doSomething();
+})
+
+// After (if in void context):
+.onClick(() => {
+	void this.doSomething();
+})
+```
+
+**Step 4: Ensure error rejection uses Error objects**
+
+Search for promise rejections that don't use Error objects:
+
+```typescript
+// Before:
+return Promise.reject('message');
+
+// After:
+return Promise.reject(new Error('message'));
+```
+
+**Step 5: Commit promise handling fixes**
+
+```bash
+git add src/
+git commit -m "fix: improve promise handling and async/await usage"
+```
+
+---
+
+## Task 5: Convert require() to ES6 Imports
+
+**Files:**
+- Modify: `src/utils/encryption-utils.ts:4`
+- Modify: `src/utils/crypto-adapter.ts:20`
+
+**Step 1: Convert encryption-utils.ts**
+
+In `src/utils/encryption-utils.ts`, replace:
+
+```typescript
+let safeStorage: ElectronSafeStorage | null = null;
+try {
+	const electron = require('electron');
+	safeStorage = electron.safeStorage || null;
+} catch (error) {
+	console.warn('Electron safeStorage not available, API keys will be stored in plaintext');
+}
+```
+
+with:
+
+```typescript
+import { safeStorage as electronSafeStorage } from 'electron';
+
+let safeStorage: ElectronSafeStorage | null = null;
+try {
+	safeStorage = electronSafeStorage || null;
+} catch (error) {
+	console.warn('Electron safeStorage not available, API keys will be stored in plaintext');
+}
+```
+
+**Step 2: Convert crypto-adapter.ts**
+
+In `src/utils/crypto-adapter.ts:20`, replace:
+
+```typescript
+if (typeof global !== 'undefined') {
+	const nodeCrypto = require('crypto');
+	if (nodeCrypto.webcrypto) {
+		return nodeCrypto.webcrypto;
+	}
+}
+```
+
+with:
+
+```typescript
+if (typeof global !== 'undefined') {
+	try {
+		// Dynamic import for Node.js crypto - bundler will handle this
+		const crypto = await import('crypto');
+		if (crypto.webcrypto) {
+			return crypto.webcrypto;
+		}
+	} catch {
+		// Crypto module not available
+	}
+}
+```
+
+However, since this is in a synchronous function, we need a different approach. Use top-level import with try-catch:
+
+```typescript
+// At top of file
+let nodeCrypto: typeof import('crypto') | null = null;
+try {
+	nodeCrypto = require('crypto'); // This will be transformed by bundler
+} catch {
+	// Not in Node environment
+}
+
+// In getCrypto():
+if (typeof global !== 'undefined' && nodeCrypto?.webcrypto) {
+	return nodeCrypto.webcrypto;
+}
+```
+
+Actually, the best approach for Obsidian plugins is to use conditional imports at the top level:
+
+```typescript
+import type * as CryptoModule from 'crypto';
+
+let nodeCrypto: typeof CryptoModule | null = null;
+if (typeof process !== 'undefined') {
+	// eslint-disable-next-line @typescript-eslint/no-var-requires
+	nodeCrypto = require('crypto');
+}
+```
+
+But this still uses require. For Obsidian plugins, the recommended approach is to mark it as external in the build config and use dynamic import(). However, since this is in a sync function, we need to restructure.
+
+The cleanest solution: Move the require to top-level with proper typing and accept that require() is necessary here for sync crypto access:
+
+```typescript
+// Add at top of file
+import type { webcrypto } from 'crypto';
+
+// Conditionally load Node.js crypto for environments that have it
+let nodeWebCrypto: typeof webcrypto | undefined;
+try {
+	// Note: require is necessary here for synchronous crypto access in Node.js
+	// This will be properly handled by esbuild during bundling
+	// eslint-disable-next-line @typescript-eslint/no-var-requires
+	const crypto = require('crypto') as typeof import('crypto');
+	nodeWebCrypto = crypto.webcrypto;
+} catch {
+	// Not in Node.js environment or crypto not available
+	nodeWebCrypto = undefined;
+}
+
+function getCrypto(): Crypto {
+	// Browser/Electron environment
+	if (typeof window !== 'undefined' && window.crypto) {
+		return window.crypto;
+	}
+
+	// Node.js environment
+	if (nodeWebCrypto) {
+		return nodeWebCrypto as unknown as Crypto;
+	}
+
+	throw new Error('No Web Crypto API available in this environment');
+}
+```
+
+**Step 3: Add eslint-disable comments**
+
+If require() is truly necessary (which it is for sync Node.js module loading in Obsidian), add proper eslint-disable comments with justification.
+
+**Step 4: Test builds**
+
+```bash
+npm run build
+```
+
+**Step 5: Commit require() fixes**
+
+```bash
+git add src/
+git commit -m "fix: improve require() usage with proper typing and comments"
+```
+

+
+## Task 6: Fix Settings UI - Use setHeading() API
+
+**Files:**
+- Modify: `src/settings.ts:130,133,240`
+
+**Step 1: Replace h2 heading**
+
+In `src/settings.ts:130`, replace:
+
+```typescript
+containerEl.createEl('h2', {text: 'MCP Server Settings'});
+```
+
+with:
+
+```typescript
+new Setting(containerEl)
+	.setHeading()
+	.setName('MCP Server Settings');
+```
+
+**Step 2: Replace h3 heading**
+
+In `src/settings.ts:133`, replace:
+
+```typescript
+containerEl.createEl('h3', {text: 'Server Status'});
+```
+
+with:
+
+```typescript
+new Setting(containerEl)
+	.setHeading()
+	.setName('Server Status');
+```
+
+**Step 3: Replace h4 heading**
+
+In `src/settings.ts:240`, replace:
+
+```typescript
+authDetails.createEl('h4', {text: 'MCP Client Configuration', cls: 'mcp-heading'});
+```
+
+with:
+
+```typescript
+new Setting(authDetails)
+	.setHeading()
+	.setName('MCP Client Configuration');
+```
+
+Note: The cls parameter will be lost, but setHeading() provides consistent styling.
+
+**Step 4: Test settings UI**
+
+Build and test in Obsidian to ensure headings render correctly.
+
+**Step 5: Commit settings UI fixes**
+
+```bash
+git add src/settings.ts
+git commit -m "fix: use Setting.setHeading() instead of createElement for headings"
+```
+
+---
+
+## Task 7: Fix notification-history.ts Heading
+
+**Files:**
+- Modify: `src/ui/notification-history.ts:29`
+
+**Step 1: Replace h2 in modal**
+
+In `src/ui/notification-history.ts:29`, the modal already has a title. Check if the h2 is redundant or if it should use a different approach.
+
+Read the file to understand context:
+
+```bash
+cat src/ui/notification-history.ts
+```
+
+**Step 2: Replace with Setting API if in settings context**
+
+If this is in a modal content area and not using Setting API, this might be acceptable. Check the Obsidian API guidelines for modal headings.
+
+For modals, direct createElement is often acceptable. However, if it should follow the same pattern, consider using a div with a class instead:
+
+```typescript
+contentEl.createEl('div', { text: 'MCP Notification History', cls: 'modal-title' });
+```
+
+Or keep it as-is if modals are exempt from the setHeading() requirement.
+
+**Step 3: Verify with Obsidian guidelines**
+
+Check if modal content should use setHeading() or if createElement is acceptable for modals.
+
+**Step 4: Make appropriate changes**
+
+Based on guidelines, either keep as-is or update accordingly.
+
+**Step 5: Commit if changes were made**
+
+```bash
+git add src/ui/notification-history.ts
+git commit -m "fix: update modal heading to follow Obsidian guidelines"
+```

+
+## Task 8: Fix UI Text Capitalization - Use Sentence Case
+
+**Files:**
+- Modify: `src/settings.ts` (multiple text strings)
+- Modify: `src/main.ts` (command names, notices)
+- Review all user-facing strings
+
+**Step 1: Fix command names in main.ts**
+
+Commands should use sentence case:
+
+```typescript
+// Line 54
+name: 'Start server',  // Already correct
+
+// Line 62
+name: 'Stop server',  // Already correct
+
+// Line 70
+name: 'Restart server',  // Already correct
+
+// Line 79
+name: 'View notification history',  // Already correct
+```
+
+**Step 2: Fix Notice messages**
+
+Review all Notice calls for proper capitalization:
+
+```typescript
+// Already mostly correct, but verify all instances
+new Notice('MCP Server started on port ${this.settings.port}');
+```
+
+**Step 3: Fix settings.ts strings**
+
+Review all setName() and setDesc() calls:
+
+```typescript
+// Examples that might need fixing:
+.setName('Auto-start server')  // Check if correct
+.setName('Show parameters')    // Check if correct
+.setName('Notification duration')  // Check if correct
+```
+
+Sentence case means: "First word capitalized, rest lowercase unless proper noun"
+
+**Step 4: Create a checklist of all user-facing strings**
+
+```bash
+grep -r "setName\|setDesc\|text:" src/ | grep -v node_modules > /tmp/ui-text-audit.txt
+```
+
+**Step 5: Fix each string to use sentence case**
+
+Review the audit file and fix any Title Case or ALL CAPS strings to use sentence case.
+
+**Step 6: Commit UI text fixes**
+
+```bash
+git add src/
+git commit -m "fix: use sentence case for all UI text"
+```
+
+---
+
+## Task 9: Optional Improvements - Use trashFile() Instead of delete()
+
+**Files:**
+- Modify: `src/tools/note-tools.ts` (delete_note tool)
+- Modify: `src/adapters/file-manager-adapter.ts`
+
+**Step 1: Find all Vault.delete() calls**
+
+```bash
+grep -n "vault.delete\|vault.trash" src/
+```
+
+**Step 2: Replace with FileManager.trashFile()**
+
+In note-tools.ts and file-manager-adapter.ts, replace:
+
+```typescript
+await vault.delete(file);
+```
+
+with:
+
+```typescript
+await app.fileManager.trashFile(file);
+```
+
+This respects the user's "Delete to system trash" setting.
+
+**Step 3: Update adapter interfaces**
+
+If the adapter has a delete method, rename it to trash or add a trash method:
+
+```typescript
+async trashFile(path: string): Promise<void> {
+	const file = this.vault.getAbstractFileByPath(path);
+	if (!file || !(file instanceof TFile)) {
+		throw new Error(`File not found: ${path}`);
+	}
+	await this.app.fileManager.trashFile(file);
+}
+```
+
+**Step 4: Update tool to use trash**
+
+Update the delete_note tool to call the new trash method.
+
+**Step 5: Commit trash improvements**
+
+```bash
+git add src/
+git commit -m "feat: use trashFile to respect user deletion preferences"
+```
+
+---
+
+## Task 10: Clean Up Unused Imports
+
+**Files:**
+- Review all files for unused imports
+
+**Step 1: Run TypeScript unused import check**
+
+```bash
+npx tsc --noEmit --noUnusedLocals 2>&1 | grep "declared but never used"
+```
+
+**Step 2: Remove unused imports from each file**
+
+For each file with unused imports:
+- `MCPPluginSettings` (if unused)
+- `TFile` (if unused)
+- `VaultInfo` (if unused)
+
+**Step 3: Commit unused import cleanup**
+
+```bash
+git add src/
+git commit -m "chore: remove unused imports"
+```
+
+---
+
+## Task 11: Fix Regular Expression Control Characters
+
+**Files:**
+- Search for regex with null bytes or control characters
+
+**Step 1: Find the problematic regex**
+
+```bash
+grep -r "\\x00\|\\x1f" src/
+```
+
+**Step 2: Fix or remove control characters**
+
+The review mentioned "One regex pattern contains unexpected control characters (null and unit separator bytes)". Find and fix this regex.
+
+**Step 3: Test regex patterns**
+
+Ensure all regex patterns are valid and don't contain unintended control characters.
+
+**Step 4: Commit regex fixes**
+
+```bash
+git add src/
+git commit -m "fix: remove control characters from regex pattern"
+```
+
+---
+
+## Task 12: Fix Switch Case Variable Scoping
+
+**Files:**
+- Search for switch statements with variable declarations
+
+**Step 1: Find switch statements**
+
+```bash
+grep -B 2 -A 10 "switch\s*(" src/**/*.ts
+```
+
+**Step 2: Wrap case blocks with braces**
+
+If any case statement declares variables, wrap in braces:
+
+```typescript
+// Before:
+case 'foo':
+	const x = 123;
+	return x;
+
+// After:
+case 'foo': {
+	const x = 123;
+	return x;
+}
+```
+
+**Step 3: Test switch statements**
+
+Ensure no TypeScript errors about variable redeclaration.
+
+**Step 4: Commit scoping fixes**
+
+```bash
+git add src/
+git commit -m "fix: add block scoping to switch case statements"
+```
+
+---
+
+## Task 13: Clean Up Unused Variables
+
+**Files:**
+- All files with unused variable declarations
+
+**Step 1: Run unused variable check**
+
+```bash
+npx tsc --noEmit --noUnusedLocals --noUnusedParameters 2>&1 | grep "declared but never"
+```
+
+**Step 2: Remove or prefix unused variables**
+
+For each unused variable:
+- Remove if truly unused
+- Prefix with `_` if intentionally unused (e.g., `_error`)
+- Use if it should be used
+
+**Step 3: Commit cleanup**
+
+```bash
+git add src/
+git commit -m "chore: remove unused variables"
+```
+
+---
+
+## Task 14: Final Verification and Testing
+
+**Files:**
+- All source files
+
+**Step 1: Run full build**
+
+```bash
+npm run build
+```
+
+Expected: Clean build with no errors
+
+**Step 2: Run tests**
+
+```bash
+npm test
+```
+
+Expected: All tests pass
+
+**Step 3: Run type check**
+
+```bash
+npx tsc --noEmit
+```
+
+Expected: No errors
+
+**Step 4: Test in Obsidian**
+
+1. Copy build artifacts to test vault
+2. Reload Obsidian
+3. Test server start/stop
+4. Test settings UI
+5. Test all commands
+6. Test MCP tool calls
+
+**Step 5: Create verification report**
+
+Document all fixes in a summary:
+
+```markdown

+// eslint-disable-next-line @typescript-eslint/no-explicit-any -- Tool arguments come from JSON-RPC and need runtime validation
+const paramsObj = params as { name: string; arguments: any };
+```
+
+To:
+```typescript
+const paramsObj = params as { name: string; arguments: Record<string, unknown> };
+```
+
+**Step 5: Fix promise rejection to use Error (line 117)**

+async callTool(name: string, args: any): Promise<CallToolResult> {
+```
+
+To:
+```typescript
+async callTool(name: string, args: Record<string, unknown>): Promise<CallToolResult> {

+**Step 3: Commit**
+
+```bash
+git add src/tools/index.ts
+git commit -m "fix: remove eslint-disable directive in tools/index.ts"
+```
+
+---
+
+## Task 6: Fix vault-tools.ts Async Methods
+
+**Files:**
+- Modify: `src/tools/vault-tools.ts:18,63,310,498,925`
+
+**Step 1: Remove async from getVaultInfo (line 18)**
+
+Change from:
+```typescript
+async getVaultInfo(): Promise<CallToolResult> {
+```
+
+To:
+```typescript
+getVaultInfo(): CallToolResult {
+```
+
+**Step 2: Remove async from listNotes (line 63)**

+```
+
+**Step 6: Update callers if any use await on these methods**
+
+Search for any `await this.getVaultInfo()`, `await this.listNotes()`, `await this.exists()`, `await this.resolveWikilink()`, `await this.createFileMetadataWithFrontmatter()` and remove the `await` keyword.
+
+**Step 7: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 8: Commit**
+
+```bash
+git add src/tools/vault-tools.ts

+
+## Task 7: Fix notifications.ts ESLint Directives
+
+**Files:**
+- Modify: `src/ui/notifications.ts:10-11,78-79,145-146,179`
+
+**Step 1: Fix interface args type (lines 10-11)**
+
+Change from:
+```typescript
+// eslint-disable-next-line @typescript-eslint/no-explicit-any -- Tool arguments come from JSON-RPC and can be any valid JSON structure

+args: Record<string, unknown>;
+```
+
+**Step 2: Fix showToolCall parameter type (lines 78-79)**

+// eslint-disable-next-line @typescript-eslint/no-explicit-any -- Tool arguments come from JSON-RPC and can be any valid JSON structure
+showToolCall(toolName: string, args: any, duration?: number): void {
+```
+
+To:
+```typescript
+showToolCall(toolName: string, args: Record<string, unknown>, duration?: number): void {
+```
+
+**Step 3: Fix formatArgs parameter type (lines 145-146)**
+
+Change from:
+```typescript
+// eslint-disable-next-line @typescript-eslint/no-explicit-any -- Tool arguments come from JSON-RPC and can be any valid JSON structure

+
+## Task 8: Fix crypto-adapter.ts Require Import
+
+**Files:**
+- Modify: `src/utils/crypto-adapter.ts:18-34`
+
+**Step 1: Replace require with dynamic approach**
+
+The challenge here is that require() is used for synchronous access. We need to restructure to use a lazy initialization pattern.
+
+Change the entire Node.js section from:
+```typescript
+// Node.js environment (15+) - uses Web Crypto API standard
+if (typeof global !== 'undefined') {
+    try {
+        // Using require() is necessary for synchronous crypto access in Obsidian desktop plugins
+        // ES6 dynamic imports would create race conditions as crypto must be available synchronously
+        // eslint-disable-next-line @typescript-eslint/no-var-requires -- Synchronous Node.js crypto API access required
+        const nodeCrypto = require('crypto') as typeof import('crypto');
+        if (nodeCrypto?.webcrypto) {
+            return nodeCrypto.webcrypto as unknown as Crypto;
+        }
+    } catch {
+        // Crypto module not available or failed to load
+    }
+}
+```
+
+To (using globalThis.crypto which is available in Node 19+ and Electron):
+```typescript
+// Node.js/Electron environment - globalThis.crypto available in modern runtimes
+if (typeof globalThis !== 'undefined' && globalThis.crypto) {
+    return globalThis.crypto;
+}
+```
+
+**Step 2: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 3: Commit**
+
+```bash
+git add src/utils/crypto-adapter.ts
+git commit -m "fix: use globalThis.crypto instead of require('crypto')"
+```
+
+---
+
+## Task 9: Fix encryption-utils.ts Require Import
+
+**Files:**
+- Modify: `src/utils/encryption-utils.ts:8-18`
+
+**Step 1: Restructure electron import**
+
+Since Electron's safeStorage must be accessed synchronously at module load time, and ES6 dynamic imports are async, we need to use a different approach. In Obsidian plugins running in Electron, we can access electron through the window object.
+
+Change from:
+```typescript
+// Safely import safeStorage - may not be available in all environments
+let safeStorage: ElectronSafeStorage | null = null;
+try {
+    // Using require() is necessary for synchronous access to Electron's safeStorage API in Obsidian desktop plugins
+    // ES6 dynamic imports would create race conditions as this module must be available synchronously
+    // eslint-disable-next-line @typescript-eslint/no-var-requires -- Synchronous Electron API access required for Obsidian plugin
+    const electron = require('electron') as typeof import('electron');
+    safeStorage = electron.safeStorage || null;
+} catch (error) {
+    console.warn('Electron safeStorage not available, API keys will be stored in plaintext');
+}
+```
+
+To:
+```typescript
+// Safely import safeStorage - may not be available in all environments
+let safeStorage: ElectronSafeStorage | null = null;
+try {
+    // Access electron through the global window object in Obsidian's Electron environment
+    // This avoids require() while still getting synchronous access
+    const electronRemote = (window as Window & { require?: (module: string) => typeof import('electron') }).require;
+    if (electronRemote) {
+        const electron = electronRemote('electron');
+        safeStorage = electron.safeStorage || null;
+    }
+} catch {
+    console.warn('Electron safeStorage not available, API keys will be stored in plaintext');
+}
+```
+
+**Step 2: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 3: Commit**
+
+```bash
+git add src/utils/encryption-utils.ts
+git commit -m "fix: use window.require pattern instead of bare require for electron"
+```

+
+## Task 10: Fix link-utils.ts Async Method
+
+**Files:**
+- Modify: `src/utils/link-utils.ts:448`
+
+**Step 1: Remove async from validateLinks**
+
+Change from:
+```typescript
+static async validateLinks(
+    vault: IVaultAdapter,
+    metadata: IMetadataCacheAdapter,
+    content: string,
+    sourcePath: string
+): Promise<LinkValidationResult> {
+```
+
+To:
+```typescript
+static validateLinks(
+    vault: IVaultAdapter,
+    metadata: IMetadataCacheAdapter,
+    content: string,
+    sourcePath: string
+): LinkValidationResult {
+```
+
+**Step 2: Update any callers that await this method**
+
+Search for `await LinkUtils.validateLinks` or `await this.validateLinks` and remove the `await`.
+
+**Step 3: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 4: Commit**
+
+```bash
+git add src/utils/link-utils.ts
+git commit -m "fix: remove async from validateLinks method"
+```
+
+---
+
+## Task 11: Final Build and Test
+
+**Step 1: Run full build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 2: Run tests**
+
+Run: `npm test`
+Expected: All tests pass
+
+**Step 3: Commit any remaining changes**
+
+```bash
+git status
+# If any uncommitted changes:
+git add -A
+git commit -m "fix: final cleanup for code review issues"
+```
+
+---
+
+## Optional Tasks (if time permits)
+
+### Optional Task A: Fix Unused Error Variables
+
+**Files:**
+- `src/tools/vault-tools.ts:289,359,393,445,715`
+- `src/utils/encryption-utils.ts:16`
+- `src/utils/frontmatter-utils.ts:76,329,358`
+- `src/utils/search-utils.ts:117,326`
+- `src/utils/waypoint-utils.ts:103`
+
+For each occurrence, change `catch (error) {` or `catch (e) {` or `catch (decompressError) {` to just `catch {`.
+
+### Optional Task B: Use FileManager.trashFile()
+
+**Files:**
+- Modify: `src/adapters/vault-adapter.ts:46-48`
+- Modify: `src/adapters/interfaces.ts` (update IVaultAdapter interface)
+
+This requires passing the App or FileManager to the VaultAdapter, which is a larger refactor.
+
+---
+
