Add support for referencing previous thoughts and tagging system: - Extended ThoughtData interface with references and tags arrays - Added getThought, searchThoughts, and getRelatedThoughts methods - Created new tools for retrieving and searching thoughts - Enhanced formatThought to display references and tags - Maintained backward compatibility with existing functionality - All changes pass TypeScript compilation
…l thinking - Comprehensive DeepThink agent implementation with 800+ lines of TypeScript - Automatic problem domain detection and complexity assessment - Confidence-driven branching and synthesis capabilities - Smart tagging system with context-aware tag generation - Specialized modes for architecture, debugging, and research analysis - Complete package configuration with build system and dependencies - Extensive documentation with README, integration guide, and examples - Practical example sessions for architecture, debugging, and research - Test suite with MCP protocol compliance verification - Implementation summary with performance characteristics and deployment options Features: - Multi-modal analysis adapting to problem types - Phase management through analysis/exploration/synthesis/validation/conclusion - Evidence tracking for research and debugging workflows - Reference building for complex reasoning chains - Integration patterns with Sequential Thinking MCP server - Performance optimizations and scalability considerations
…rver Merged features from separate worktrees: - References and tagging system (from sequential-thinking-references) - Confidence scoring and evidence tracking (from sequential-thinking-confidence) - Synthesis and insights generation (from sequential-thinking-synthesis) Complete feature set now includes: - Original sequential thinking functionality (preserved) - Thought references and tagging for organization - Confidence levels (0-1 scale) with visual indicators - Evidence arrays to support reasoning - Assumptions tracking for risk assessment - Advanced reasoning quality analysis - Comprehensive synthesis tool extracting decisions, risks, action items - Enhanced visualization with evidence and assumption displays - All 5 tools: sequential_thinking, get_thought, search_thoughts, get_related_thoughts, synthesize_thoughts Maintains full backward compatibility while adding powerful new capabilities for structured reasoning analysis and insight extraction.
Features: - New auto_think tool using MCP sampling for autonomous thought generation - Smart context analysis of existing thoughts and confidence gaps - Intelligent prompt generation based on problem domains - Auto-enhancement with confidence, tags, evidence, and references - Reference detection linking thoughts together - Adaptive stopping based on completion signals - Integration with all existing tools and synthesis This creates an autonomous reasoning system where the server drives its own thinking process using Claude's capabilities through MCP sampling.
- Replace server.request() with server.createMessage() for proper MCP sampling - Add sampling capability declaration to server capabilities - Add client capability checking for graceful error handling - Implement rule-based fallback when MCP sampling unavailable - Add contextual thought generation with heuristic tagging and references - Update tool description to reflect dual-mode operation - Create test example demonstrating fixed functionality The autonomous thinking feature now works reliably with or without MCP sampling support.
- Add useSubagent parameter to auto_think tool (default: false) - When useSubagent=true, analyzes context and returns structured prompts for specialized subagents - Supports 7 subagent types: technical-analyst, research-specialist, risk-assessor, strategic-planner, quality-reviewer, deep-reasoner, general-reasoner - Context analysis identifies problem domains, confidence gaps, evidence needs, and assumption risks - Generates comprehensive prompts with role descriptions, current context, critical issues, and expected output format - Creates meta-reasoning system for intelligent delegation to specialized thinking agents - Maintains backward compatibility with existing direct auto-thinking mode
