Implementation Reference

• src/index.ts:216-249 (handler)

  The switch case handler that executes the 'begin_feature_discussion' tool. It generates a feature ID, initializes the feature discussion object with the provided title and sets the first prompt, creates discussion context, and returns a response with the feature ID and initial prompt.

  case "begin_feature_discussion": {
    const { title } = request.params.arguments as any;
    const id = `f${Object.keys(featureDiscussions).length + 1}`;
  
    // Initialize new feature discussion
    featureDiscussions[id] = {
      id,
      title,
      description: "",
      requirements: [],
      status: 'in-discussion',
      createdAt: new Date().toISOString(),
      updatedAt: new Date().toISOString(),
      currentPrompt: FEATURE_DISCUSSION_PROMPTS[0].id
    };
  
    // Initialize discussion context
    discussionContexts[id] = {
      previousDecisions: [],
      relatedFeatures: [],
      technicalConstraints: [],
      conversationHistory: []
    };
  
    // Return the first prompt
    return {
      content: [
        {
          type: "text",
          text: `Feature discussion started for: ${title}\n\nFeature ID: ${id}\n\nFirst question:\n${FEATURE_DISCUSSION_PROMPTS[0].message}`
        }
      ]
    };
  }

• src/index.ts:175-188 (registration)

  Registers the 'begin_feature_discussion' tool by defining its name, description, and input schema (requiring a 'title' string) in the ListToolsRequestSchema handler.

  {
    name: "begin_feature_discussion",
    description: "Start a new feature discussion",
    inputSchema: {
      type: "object",
      properties: {
        title: {
          type: "string",
          description: "Title or name of the feature"
        }
      },
      required: ["title"]
    }
  },

• src/index.ts:76-117 (helper)

  Defines the array of sequential prompts used throughout feature discussions. The 'begin_feature_discussion' tool initializes new discussions with the first prompt from this array ('initial_description').

  const FEATURE_DISCUSSION_PROMPTS: FeaturePrompt[] = [
    {
      id: "initial_description",
      message: "Please provide a brief description of the feature you'd like to discuss.",
      field: "description"
    },
    {
      id: "business_value",
      message: "What business value does this feature provide? How does it benefit users or stakeholders?",
      field: "businessValue"
    },
    {
      id: "target_users",
      message: "Who are the target users for this feature?",
      field: "targetUsers"
    },
    {
      id: "requirements",
      message: "What are the key requirements or constraints for this feature?",
      field: "requirements"
    },
    {
      id: "success_criteria",
      message: "What are the success criteria for this feature? How will we know it's working as intended?",
      field: "successCriteria"
    },
    {
      id: "technical_approach",
      message: "Do you have any specific technical approach in mind for implementing this feature?",
      field: "technicalApproach"
    },
    {
      id: "risks",
      message: "Are there any potential risks or challenges we should consider?",
      field: "risks"
    },
    {
      id: "timeline",
      message: "What's the desired timeline or priority for this feature?",
      field: "timeline"
    }
  ];
