 # Changelog
 
+## 2025-09-28 - 0.6.1 - fix(provider.anthropic)
+Fix Anthropic research tool identifier and add tests + local Claude permissions
+
+- Replace Anthropic research tool type from 'computer_20241022' to 'web_search_20250305' to match the expected web-search tool schema.
+- Add comprehensive test suites and fixtures for providers and research features (new/updated tests under test/ including anthropic, openai, research.* and stubs).
+- Fix test usage of XAI provider class name (use XAIProvider) and adjust basic provider test expectations (provider instantiation moved to start()).
+- Add .claude/settings.local.json with local Claude permissions to allow common CI/dev commands and web search during testing.
+
+## 2025-09-28 - 0.6.0 - feat(research)
+Introduce research API with provider implementations, docs and tests
+
+- Add ResearchOptions and ResearchResponse interfaces and a new abstract research() method to MultiModalModel
+- Implement research() for OpenAiProvider (deep research model selection, optional web search/tools, background flag, source extraction)
+- Implement research() for AnthropicProvider (web search tool support, domain filters, citation extraction)
+- Implement research() for PerplexityProvider (sonar / sonar-pro model usage and citation parsing)
+- Add research() stubs to Exo, Groq, Ollama and XAI providers that throw a clear 'not yet supported' error to preserve interface compatibility
+- Add tests for research interfaces and provider research methods (test files updated/added)
+- Add documentation: readme.research.md describing the research API, usage and configuration
+- Export additional providers from ts/index.ts and update provider typings/imports across files
+- Add a 'typecheck' script to package.json
+- Add .claude/settings.local.json (local agent permissions for CI/dev tasks)
+
 ## 2025-08-12 - 0.5.11 - fix(openaiProvider)
 Update default chat model to gpt-5-mini and bump dependency versions

+# SmartAI Research API Implementation
+
+This document describes the new research capabilities added to the SmartAI library, enabling web search and deep research features for OpenAI and Anthropic providers.
+
+## Features Added
+
+### 1. Research Method Interface
+
+Added a new `research()` method to the `MultiModalModel` abstract class with the following interfaces:
+
+```typescript
+interface ResearchOptions {
+  query: string;
+  searchDepth?: 'basic' | 'advanced' | 'deep';
+  maxSources?: number;
+  includeWebSearch?: boolean;
+  background?: boolean;
+}
+
+interface ResearchResponse {
+  answer: string;
+  sources: Array<{
+    url: string;
+    title: string;
+    snippet: string;
+  }>;
+  searchQueries?: string[];
+  metadata?: any;
+}
+```
+
+### 2. OpenAI Provider Research Implementation
+
+The OpenAI provider now supports:
+- **Deep Research API** with models:
+  - `o3-deep-research-2025-06-26` (comprehensive analysis)
+  - `o4-mini-deep-research-2025-06-26` (lightweight, faster)
+- **Web Search** for standard models (gpt-5, o3, o3-pro, o4-mini)
+- **Background processing** for async deep research tasks
+
+### 3. Anthropic Provider Research Implementation
+
+The Anthropic provider now supports:
+- **Web Search API** with Claude models
+- **Domain filtering** (allow/block lists)
+- **Progressive searches** for comprehensive research
+- **Citation extraction** from responses
+
+### 4. Perplexity Provider Research Implementation
+
+The Perplexity provider implements research using:
+- **Sonar models** for standard searches
+- **Sonar Pro** for deep research
+- Built-in citation support
+
+### 5. Other Providers
+
+Added research method stubs to:
+- Groq Provider
+- Ollama Provider
+- xAI Provider
+- Exo Provider
+
+These providers throw a "not yet supported" error when research is called, maintaining interface compatibility.
+
+## Usage Examples
+
+### Basic Research with OpenAI
+
+```typescript
+import { OpenAiProvider } from '@push.rocks/smartai';
+
+const openai = new OpenAiProvider({
+  openaiToken: 'your-api-key',
+  researchModel: 'o4-mini-deep-research-2025-06-26'
+});
+
+await openai.start();
+
+const result = await openai.research({
+  query: 'What are the latest developments in quantum computing?',
+  searchDepth: 'basic',
+  includeWebSearch: true
+});
+
+console.log(result.answer);
+console.log('Sources:', result.sources);
+```
+
+### Deep Research with OpenAI
+
+```typescript
+const deepResult = await openai.research({
+  query: 'Comprehensive analysis of climate change mitigation strategies',
+  searchDepth: 'deep',
+  background: true
+});
+```
+
+### Research with Anthropic
+
+```typescript
+import { AnthropicProvider } from '@push.rocks/smartai';
+
+const anthropic = new AnthropicProvider({
+  anthropicToken: 'your-api-key',
+  enableWebSearch: true,
+  searchDomainAllowList: ['nature.com', 'science.org']
+});
+
+await anthropic.start();
+
+const result = await anthropic.research({
+  query: 'Latest breakthroughs in CRISPR gene editing',
+  searchDepth: 'advanced'
+});
+```
+
+### Research with Perplexity
+
+```typescript
+import { PerplexityProvider } from '@push.rocks/smartai';
+
+const perplexity = new PerplexityProvider({
+  perplexityToken: 'your-api-key'
+});
+
+const result = await perplexity.research({
+  query: 'Current state of autonomous vehicle technology',
+  searchDepth: 'deep' // Uses Sonar Pro model
+});
+```
+
+## Configuration Options
+
+### OpenAI Provider
+- `researchModel`: Specify deep research model (default: `o4-mini-deep-research-2025-06-26`)
+- `enableWebSearch`: Enable web search for standard models
+
+### Anthropic Provider
+- `enableWebSearch`: Enable web search capabilities
+- `searchDomainAllowList`: Array of allowed domains
+- `searchDomainBlockList`: Array of blocked domains
+
+## API Pricing
+
+- **OpenAI Deep Research**: $10 per 1,000 calls
+- **Anthropic Web Search**: $10 per 1,000 searches + standard token costs
+- **Perplexity Sonar**: $5 per 1,000 searches (Sonar Pro)
+
+## Testing
+
+Run the test suite:
+
+```bash
+pnpm test test/test.research.ts
+```
+
+All providers have been tested to ensure:
+- Research methods are properly exposed
+- Interfaces are correctly typed
+- Unsupported providers throw appropriate errors
+
+## Next Steps
+
+Future enhancements could include:
+1. Implementing Google Gemini Grounding API support
+2. Adding Brave Search API integration
+3. Implementing retry logic for rate limits
+4. Adding caching for repeated queries
+5. Supporting batch research operations
+
+## Notes
+
+- The implementation maintains backward compatibility
+- All existing methods continue to work unchanged
+- Research capabilities are optional and don't affect existing functionality
