+
+## Plan 4.2: Test Web Search Capabilities and Integration
+
+### Objective
+Test and verify that the OpenCode AI assistant can successfully perform web searches through the configured MCP servers.
+
+**Purpose:** Ensure the web search functionality is working correctly and integrate it with the AI assistant's capabilities.
+
+**Output:** Test results confirming web search functionality through MCP servers and documentation of the integration.

+**Project Context:**
+- MCP servers (Context7 and DuckDuckGo) should be configured from Plan 1
+- OpenCode service needs to be running to test web search functionality
+- Testing should verify both MCP servers are functional and accessible

+- [ ] DuckDuckGo web search returns valid, relevant results
+- [ ] AI assistant properly interprets and formats search results
+- [ ] Web search capabilities are documented
+- [ ] No errors in service logs during web search operations
+
+### Success Criteria
+- All tasks completed successfully
+- Web search functionality through both MCP servers is working
+- AI assistant can effectively use web search capabilities
+- Configuration and usage are properly documented
+- No errors or warnings introduced in the configuration
+- Phase 4 (Internet Access & MCP) is complete
+
+### Output
+After completion, create `.planning/phases/04-internet-access/04-02-SUMMARY.md`:
