• src/index-backup.ts:275-328 (handler)

  The core handler function for the 'get_thinking_summary' tool. It checks if there are thinking steps, generates a formatted summary of all steps including status, timestamps, reasoning, and categories, and returns it as text content. Handles empty session and errors.

    async () => {
      try {
        if (thinkingSession.currentSteps.length === 0) {
          return {
            content: [{
              type: "text",
              text: "📝 **No Active Thinking Session**\n\nUse 'sequential_thinking' to start your first thought."
            }]
          };
        }
        
        const targetSteps = thinkingSession.metadata?.target_steps;
        const progress = targetSteps ? ` (${thinkingSession.currentSteps.length}/${targetSteps})` : '';
        
        let content = `📋 **Thinking Session Summary${progress}**\n\n`;
        content += `**Status**: ${thinkingSession.isComplete ? 'Complete ✅' : 'In Progress 🔄'}\n`;
        content += `**Total Steps**: ${thinkingSession.currentSteps.length}\n`;
        content += `**Started**: ${thinkingSession.currentSteps[0]?.timestamp ? new Date(thinkingSession.currentSteps[0].timestamp).toLocaleString() : 'Unknown'}\n\n`;
        
        content += "**Complete Thinking Chain:**\n";
        thinkingSession.currentSteps.forEach((step, index) => {
          const categoryLabel = step.category ? ` [${step.category}]` : '';
          content += `**${step.id}.${categoryLabel}** ${step.thought}\n`;
          if (step.reasoning) {
            content += `   *Reasoning: ${step.reasoning}*\n`;
          }
          content += '\n';
        });
        
        if (thinkingSession.summary) {
          content += `**Session Summary**: ${thinkingSession.summary}\n`;
        }
        
        if (thinkingSession.pdfContext) {
          content += `**PDF Context**: ${thinkingSession.pdfContext.filename || 'Document loaded'}\n`;
        }
        
        return {
          content: [{
            type: "text", 
            text: content
          }]
        };
        
      } catch (error) {
        return {
          content: [{
            type: "text",
            text: `❌ **Error getting thinking summary**: ${error instanceof Error ? error.message : String(error)}`
          }]
        };
      }
    }
  );

• src/index-backup.ts:271-328 (registration)

  MCP tool registration using server.tool(). Registers 'get_thinking_summary' with empty input schema {} and inline async handler function. No parameters required.

  server.tool(
    "get_thinking_summary",
    "Get a complete summary of the current thinking session with all steps and analysis",
    {},
    async () => {
      try {
        if (thinkingSession.currentSteps.length === 0) {
          return {
            content: [{
              type: "text",
              text: "📝 **No Active Thinking Session**\n\nUse 'sequential_thinking' to start your first thought."
            }]
          };
        }
        
        const targetSteps = thinkingSession.metadata?.target_steps;
        const progress = targetSteps ? ` (${thinkingSession.currentSteps.length}/${targetSteps})` : '';
        
        let content = `📋 **Thinking Session Summary${progress}**\n\n`;
        content += `**Status**: ${thinkingSession.isComplete ? 'Complete ✅' : 'In Progress 🔄'}\n`;

          }
          content += '\n';
        });
        
        if (thinkingSession.summary) {
          content += `**Session Summary**: ${thinkingSession.summary}\n`;
        }

            text: content
          }]

        return {
          content: [{

        };
      }
    }
  );

• src/index-backup.ts:274-274 (schema)

  Empty Zod schema indicating the tool takes no input parameters.

  {},

• src/index-backup.ts:58-62 (helper)

  Global thinkingSession state object used by the tool to store and retrieve the list of thinking steps for summarization.

  let thinkingSession: ThinkingSession = {
    currentSteps: [],
    totalSteps: 0,
    isComplete: false
  };
