Implementation Reference

• vibe-services/context-manager/index.ts:118-138 (handler)

  Core handler function that loads the current project, reads the PRD template from a prompt file, replaces the project name placeholder, creates the necessary directory, writes the PRD to '0_discovery/requirements/PRODUCT_REQUIREMENTS_DOCUMENT.md', and returns a success message.

  async generateProjectPRD(): Promise<string> {
    const project = this.loadCurrentProject();
    if (!project) {
      throw new Error('No active project found. Please start clarification first.');
    }
  
    const promptPath = resolve(__dirname, '../../../.vibecoding/prompts/workflows/discovery-phase.md');
    let prdContent = `Failed to load PRD template.`;
    if (existsSync(promptPath)) {
      prdContent = readFileSync(promptPath, 'utf-8');
    }
    
    prdContent = prdContent.replace(/{{projectName}}/g, project.name);
  
    const outputPath = join(project.path, '0_discovery', 'requirements', 'PRODUCT_REQUIREMENTS_DOCUMENT.md');
    
    mkdirSync(path.dirname(outputPath), { recursive: true });
    writeFileSync(outputPath, prdContent);
  
    return `✅ PRD document generated and saved to: ${outputPath}`;
  }

• vibe-services/context-manager/index.ts:211-219 (registration)

  Tool registration in the ListTools response, including name, description, and empty input schema.

  {
    name: 'generate-prd',
    description: 'Generate a project PRD and save it to the project structure',
    inputSchema: {
      type: 'object',
      properties: {},
      required: []
    }
  },

• vibe-services/context-manager/index.ts:268-278 (handler)

  Dispatch handler in the CallToolRequestSchema that invokes the generateProjectPRD method and formats the response.

  case 'generate-prd': {
    const resultMessage = await contextManager.generateProjectPRD();
    return {
      content: [
        {
          type: 'text',
          text: resultMessage
        }
      ]
    };
  }

• vibe-services/context-manager/index.ts:214-218 (schema)

  Input schema for the tool, which is an empty object (no required parameters).

  inputSchema: {
    type: 'object',
    properties: {},
