 # Changelog
 
+## 2025-10-30 - 0.8.0 - feat(provider.anthropic)
+Add extended thinking modes to AnthropicProvider and apply thinking budgets to API calls
+
+- Introduce IAnthropicProviderOptions.extendedThinking to configure thinking modes: 'quick' | 'normal' | 'deep' | 'off'.
+- Add getThinkingConfig() helper mapping modes to token budgets (quick=2048, normal=8000, deep=16000, off=0).
+- Apply thinking configuration to Anthropic API calls (chat, chatStream, vision, document, research) and increase max_tokens where appropriate (up to 20000).
+- Add comprehensive tests (test/test.thinking.anthropic.ts) and update readme.hints.md with usage examples and recommendations.
+- Add .claude/settings.local.json for local assistant permissions used in development/testing.
+
+## 2025-10-10 - 0.7.7 - fix(MultiModalModel)
+Lazy-load SmartPdf and guard document processing across providers; ensure SmartPdf is initialized only when needed
+
+- Make SmartPdf lazy-loaded: smartpdfInstance is now nullable and no longer started automatically in start()
+- Add ensureSmartpdfReady() to initialize and start SmartPdf on demand before document processing
+- Providers updated (OpenAI, Anthropic, Ollama, xAI) to call ensureSmartpdfReady() and use the smartpdfInstance for PDF -> image conversion
+- stop() now cleans up and nullifies smartpdfInstance to release resources
+- Avoids starting a browser/process unless document() is actually used (reduces unnecessary resource usage)
+- Add local Claude permissions file (.claude/settings.local.json) for tooling/configuration
+
+## 2025-10-09 - 0.7.6 - fix(provider.elevenlabs)
+Provide default ElevenLabs TTS voice fallback and add local tool/project configs
+
+- ElevenLabsProvider: fallback to Samara voice id ('19STyYD15bswVz51nqLf') when no voiceId or defaultVoiceId is provided — avoids throwing an error on TTS calls.
+- ElevenLabsProvider: continue to use 'eleven_v3' as the default model for TTS.
+- Add .claude/settings.local.json with expanded allowed permissions for local tooling and web search.
+- Add .serena/project.yml and .serena/.gitignore to include Serena project configuration and ignore cache.
+
 ## 2025-10-08 - 0.7.5 - fix(provider.elevenlabs)
 Update ElevenLabs default TTS model to eleven_v3 and add local Claude permissions file

+# SmartAI Project Hints
+
+## Anthropic Extended Thinking Feature
+
+### Overview
+The Anthropic provider now supports extended thinking by default across all methods. Extended thinking enables Claude to spend more time reasoning about complex problems before generating responses, leading to higher quality answers for difficult questions.
+
+### Configuration
+
+Extended thinking is configured at the provider level during instantiation:
+
+```typescript
+import * as smartai from '@push.rocks/smartai';
+
+const provider = new smartai.AnthropicProvider({
+  anthropicToken: 'your-token-here',
+  extendedThinking: 'normal', // Options: 'quick' | 'normal' | 'deep' | 'off'
+});
+```
+
+### Thinking Modes
+
+The `extendedThinking` parameter accepts four modes:
+
+| Mode | Budget Tokens | Use Case |
+|------|---------------|----------|
+| `'quick'` | 2,048 | Lightweight reasoning for simple queries |
+| `'normal'` | 8,000 | **Default** - Balanced reasoning for most tasks |
+| `'deep'` | 16,000 | Complex reasoning for difficult problems |
+| `'off'` | 0 | Disable extended thinking |
+
+**Default Behavior**: If `extendedThinking` is not specified, it defaults to `'normal'` mode (8,000 tokens).
+
+### Supported Methods
+
+Extended thinking is automatically applied to all Anthropic provider methods:
+- `chat()` - Synchronous chat
+- `chatStream()` - Streaming chat
+- `vision()` - Image analysis
+- `document()` - PDF document processing
+- `research()` - Web research with citations
+
+### Token Budget Constraints
+
+**Important**: The thinking budget must be less than `max_tokens` for the API call. The current `max_tokens` values are:
+
+- `chatStream()`: 20,000 tokens (sufficient for all modes ✓)
+- `chat()`: 20,000 tokens (sufficient for all modes ✓)
+- `vision()`: 10,000 tokens (sufficient for all modes ✓)
+- `document()`: 20,000 tokens (sufficient for all modes ✓)
+- `research()`: 20,000 tokens for all searchDepth levels (sufficient ✓)
+
+### Performance and Cost Implications
+
+**Token Usage**:
+- You are charged for the **full thinking tokens** generated, not just the summary
+- Higher thinking budgets may result in more thorough reasoning but increased costs
+- The budget is a **target**, not a strict limit - actual usage may vary
+
+**Response Quality**:
+- `'quick'`: Fast responses, basic reasoning
+- `'normal'`: Good balance between quality and speed (recommended for most use cases)
+- `'deep'`: Highest quality reasoning for complex problems, slower responses
+
+**Recommendations**:
+- Start with `'normal'` (default) for general usage
+- Use `'deep'` for complex analytical tasks, philosophy, mathematics, or research
+- Use `'quick'` for simple factual queries where deep reasoning isn't needed
+- Use `'off'` only if you want traditional Claude behavior without extended thinking
+
+### Usage Examples
+
+#### Example 1: Default (Normal Mode)
+```typescript
+const provider = new smartai.AnthropicProvider({
+  anthropicToken: process.env.ANTHROPIC_TOKEN,
+  // extendedThinking defaults to 'normal'
+});
+
+await provider.start();
+
+const response = await provider.chat({
+  systemMessage: 'You are a helpful assistant.',
+  userMessage: 'Explain the implications of quantum computing.',
+  messageHistory: [],
+});
+```
+
+#### Example 2: Deep Thinking for Complex Analysis
+```typescript
+const provider = new smartai.AnthropicProvider({
+  anthropicToken: process.env.ANTHROPIC_TOKEN,
+  extendedThinking: 'deep', // 16,000 token budget
+});
+
+await provider.start();
+
+const response = await provider.chat({
+  systemMessage: 'You are a philosopher and ethicist.',
+  userMessage: 'Analyze the trolley problem from multiple ethical frameworks.',
+  messageHistory: [],
+});
+```
+
+#### Example 3: Quick Mode for Simple Queries
+```typescript
+const provider = new smartai.AnthropicProvider({
+  anthropicToken: process.env.ANTHROPIC_TOKEN,
+  extendedThinking: 'quick', // 2,048 token budget
+});
+
+await provider.start();
+
+const response = await provider.chat({
+  systemMessage: 'You are a helpful assistant.',
+  userMessage: 'What is the capital of France?',
+  messageHistory: [],
+});
+```
+
+#### Example 4: Disable Thinking
+```typescript
+const provider = new smartai.AnthropicProvider({
+  anthropicToken: process.env.ANTHROPIC_TOKEN,
+  extendedThinking: 'off', // No extended thinking
+});
+
+await provider.start();
+
+const response = await provider.chat({
+  systemMessage: 'You are a helpful assistant.',
+  userMessage: 'Tell me a joke.',
+  messageHistory: [],
+});
+```
+
+#### Example 5: Extended Thinking with Vision
+```typescript
+const provider = new smartai.AnthropicProvider({
+  anthropicToken: process.env.ANTHROPIC_TOKEN,
+  extendedThinking: 'normal',
+});
+
+await provider.start();
+
+const imageBuffer = await fs.promises.readFile('./image.jpg');
+const analysis = await provider.vision({
+  image: imageBuffer,
+  prompt: 'Analyze this image in detail and explain what you see.',
+});
+```
+
+### Testing
+
+Comprehensive tests for extended thinking are available in:
+- `test/test.thinking.anthropic.ts` - Tests all thinking modes
+
+Run tests with:
+```bash
+pnpm test
+```
+
+Run specific thinking tests:
+```bash
+npx tstest test/test.thinking.anthropic.ts --verbose
+```
+
+### API Reference
+
+According to Anthropic's documentation:
+- Extended thinking is supported on Claude Sonnet 4.5, 4, 3.7, Haiku 4.5, and Opus 4.1, 4
+- The current model used is `claude-sonnet-4-5-20250929`
+- Minimum thinking budget is 1,024 tokens
+- Thinking budget must be less than `max_tokens`
+
+### Implementation Details
+
+The extended thinking feature is implemented via:
+1. **Interface**: `IAnthropicProviderOptions.extendedThinking` property
+2. **Helper Method**: `getThinkingConfig()` private method that maps modes to token budgets
+3. **API Parameter**: Adds `thinking: { type: 'enabled', budget_tokens: number }` to all API calls
+
+The thinking configuration is applied automatically to all API calls when the provider is instantiated.
