1.0.0-alpha.5

Replace the gitea-release-action with direct API calls using curl.
This approach works on both GitHub (which runs this step conditionally)
and Gitea servers, using their compatible REST APIs.

-# 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`)

-
-## Required Fields
-
-The `manifest.json` must include:

-- `name` - Display name
-- `version` - Semantic Versioning `x.y.z`
-- `minAppVersion` - Minimum Obsidian version required

-## 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

-
-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"

-# Versioning & Releases
-
-## 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**

-- 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):

+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.)

+
+## Development Setup
+
+1. **Fork and clone the repository:**
+   ```bash
+   git clone https://github.com/YOUR_USERNAME/obsidian-mcp-server.git
+   cd obsidian-mcp-server
+   ```
+
+2. **Install dependencies:**
+   ```bash
+   npm install
+   ```
+
+3. **Link to your vault for testing:**
+
+   Create a symlink from your vault's plugins folder to your development directory:
+
+   **Linux/macOS:**
+   ```bash
+   ln -s /path/to/your/dev/obsidian-mcp-server /path/to/vault/.obsidian/plugins/obsidian-mcp-server
+   ```
+
+   **Windows (Command Prompt as Administrator):**
+   ```cmd
+   mklink /D "C:\path\to\vault\.obsidian\plugins\obsidian-mcp-server" "C:\path\to\your\dev\obsidian-mcp-server"
+   ```
+
+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!

-
-### Tools not working
-
-**Path errors**
-- Use relative paths from vault root
-- Example: `folder/note.md` not `/full/path/to/note.md`
-
-**Permission errors**
-- Ensure Obsidian has file system access
-- Check vault is not read-only
-
-## 🎯 Next Steps
-
-- Read the full [README.md](README.md) for detailed documentation
-- Explore the [MCP Protocol Documentation](https://modelcontextprotocol.io)
-- Check example requests in the README
-- Customize settings for your workflow
-
-## 💡 Tips
-
-- Use the ribbon icon for quick server toggle
-- Enable auto-start for seamless integration
-- Use authentication for additional security
-- Monitor the status bar for server state
-- Check Obsidian console (Ctrl+Shift+I) for detailed logs

+## 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

-3. Re-enable it
-4. Watch for errors in console
-
-## Server Won't Start
-
-### Port Already in Use
-
-**Error**: "Port 3000 is already in use"
-
-**Solution**:
-1. Go to **Settings** → **MCP Server**
-2. Change port to something else (e.g., 3001, 3002)
-3. Try starting again
-
-Or find and kill the process using port 3000:
-```bash
-# Linux/Mac
-lsof -i :3000
-kill -9 <PID>
-
-# Windows
-netstat -ano | findstr :3000
-taskkill /PID <PID> /F
-```
-
-### Module Not Found
-
-**Error**: "Cannot find module 'express'" or similar
-
-**Solution**:
-```bash
-cd /path/to/vault/.obsidian/plugins/obsidian-mcp-server
-npm install
-npm run build
-```
-
-Restart Obsidian.
-
-### Permission Denied
-
-**Error**: "EACCES" or "Permission denied"
-
-**Solution**:
-- Try a different port (above 1024)
-- Check firewall settings
-- Run Obsidian with appropriate permissions
-
-## Server Starts But Can't Connect
-
-### Check Server is Running
-
-Look at the status bar (bottom of Obsidian):
-- Should show: `MCP: Running (3000)`
-- If shows: `MCP: Stopped` - server isn't running
-
-### Test Health Endpoint
-
-Open browser or use curl:
-```bash
-curl http://127.0.0.1:3000/health
-```
-
-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
-
-## Getting Help

+# 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

-│   └── obsidian.ts            # Existing Obsidian mocks (minimal usage going forward)
-```
-
-### 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 {

-    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

-- Refactored VaultTools class using adapters
-- `createVaultTools()` factory function
-- Updated vault-tools.test.ts using mock adapters
-- New tests for uncovered lines:
-  - 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 existing tests pass
-- No breaking changes to public API
-
-### Phase 3: NoteTools Refactoring
-**Deliverables:**

-- Build succeeding with no errors
-
-**Success Criteria:**
-- 100% test coverage: statements, branches, functions, lines
-- 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**
-- Mitigation: Centralized mock factories reduce duplication
-- Cleaner mocks are easier to maintain than complex App mocks
-
-## Success Metrics
-
-**Coverage Goals:**
-- Statement coverage: 100%
-- Branch coverage: 100%
-- Function coverage: 100%
-- Line coverage: 100%
-
-**Quality Goals:**
-- All existing tests pass
-- No type errors in build
-- Plugin functions correctly in Obsidian
-- 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)
+ */
+
+/**
+ * Gets the appropriate Crypto interface for the current environment
+ * @returns Crypto interface with getRandomValues method
+ * @throws Error if no crypto API is available
+ */
+function getCrypto(): Crypto {
+	// Browser/Electron environment
+	if (typeof window !== 'undefined' && window.crypto) {
+		return window.crypto;
+	}
+
+	// Node.js environment (15+) - uses Web Crypto API standard
+	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
+ */
+export function getCryptoRandomValues<T extends ArrayBufferView>(array: T): T {
+	return getCrypto().getRandomValues(array);
+}
+```
+
+### File: `src/utils/auth-utils.ts` (modified)
+
+```typescript
+import { getCryptoRandomValues } from './crypto-adapter';
+
+/**
+ * Generates a cryptographically secure random API key
+ * @param length Length of the API key (default: 32 characters)
+ * @returns A random API key string
+ */
+export function generateApiKey(length: number = 32): string {
+	const charset = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_';
+	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;
+}
+
+// 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', () => {

+	});
+});

+
+**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)

+ * @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 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**
+

+/**
+ * Validates API key strength
+ * @param apiKey The API key to validate

+ */
+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
