Implementation Reference

• src/tools/reasoning-wrapper.ts:73-121 (handler)

  The handler function for the 'reason_beam' tool. It simulates Beam Search reasoning over 3 iterative steps, building thoughts progressively, and returns a JSON-structured response containing all thoughts, strategy details, and completion status.

  async ({ query }) => {
    try {
      // Initialize first thought
      const totalThoughts = 3;
      let currentThought = `Beam Search Reasoning (Step 1/${totalThoughts}): Initial analysis of the problem "${query}":\n\n` +
                           `Let me explore multiple approaches to this problem. ${query}\n\n` +
                           `[This would be the initial Beam Search-based reasoning]`;
      let thoughtNumber = 1;
      let complete = false;
      let allThoughts = [currentThought];
      
      // Automatically iterate through all thoughts
      while (!complete && thoughtNumber < totalThoughts) {
        // Simulate next thought generation
        thoughtNumber++;
        const nextThought = `Beam Search Reasoning (Step ${thoughtNumber}/${totalThoughts}): ` +
                           `Considering 3 alternative paths from "${currentThought.slice(0, 50)}...", ` +
                           `the most promising direction is...\n\n` +
                           `[This would be the next step of Beam Search reasoning for: ${query}]`;
        
        allThoughts.push(nextThought);
        currentThought = nextThought;
        
        // Check if we've reached the final thought
        if (thoughtNumber >= totalThoughts) {
          complete = true;
        }
      }
      
      // Final result with all thoughts
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify({
              strategy: "beam_search",
              originalPrompt: query,
              allThoughts: allThoughts,
              thoughtNumber: thoughtNumber,
              totalThoughts: totalThoughts,
              complete: true
            }, null, 2)
          }
        ]
      };
    } catch (error) {
      throw new ReasoningError(`Beam Search reasoning command failed: ${error instanceof Error ? error.message : String(error)}`);
    }
  }

• src/tools/reasoning-wrapper.ts:70-72 (schema)

  The input schema for the 'reason_beam' tool, defining a single 'query' string parameter using Zod validation.

  {
    query: z.string().describe("The problem or task to reason about using Beam Search")
  },

• src/tools/reasoning-wrapper.ts:68-122 (registration)

  The registration of the 'reason_beam' tool using server.tool(), including the tool name, input schema, and handler function within the registerCommandWrappers function.

  server.tool(
    "reason_beam",
    {
      query: z.string().describe("The problem or task to reason about using Beam Search")
    },
    async ({ query }) => {
