• src/tools/get-specification-details.ts:50-100 (handler)

  The main handler function that executes the tool logic: fetches specification details via API manager and formats the response according to the specified format (agent_ready, summary, detailed).

  async execute(args: GetSpecificationDetailsArgs) {
    try {
      const details = await this.apiManager.getSpecificationDetails(args.specification_id);
  
      const format = args.format || 'agent_ready';
  
      switch (format) {
        case 'agent_ready':
          return {
            content: [
              {
                type: 'text',
                text: JSON.stringify(this.formatForAgent(details, args), null, 2)
              }
            ]
          };
  
        case 'summary':
          return {
            content: [
              {
                type: 'text',
                text: this.formatSummary(details, args)
              }
            ]
          };
  
        case 'detailed':
        default:
          return {
            content: [
              {
                type: 'text',
                text: this.formatDetailed(details, args)
              }
            ]
          };
      }
  
    } catch (error) {
      return {
        content: [
          {
            type: 'text',
            text: `Error retrieving specification details: ${error instanceof Error ? error.message : 'Unknown error'}`
          }
        ],

    }

• src/tools/get-specification-details.ts:17-48 (schema)

  Tool definition including name, description, and inputSchema for validation (specification_id required, optional flags for content/dependencies/format). Also defines the TypeScript interface GetSpecificationDetailsArgs above.

  getDefinition() {
    return {
      name: 'get_specification_details',
      description: 'Get comprehensive details about a specific 3GPP specification including metadata, content, dependencies, and related information.',
      inputSchema: {
        type: 'object',
        properties: {
          specification_id: {
            type: 'string',
            description: 'The specification ID (e.g., "TS 32.290", "TS 38.331", "TS 33.501")'
          },
          include_content: {
            type: 'boolean',
            description: 'Include detailed content from TSpec-LLM dataset (default: true)',
            default: true
          },
          include_dependencies: {
            type: 'boolean',
            description: 'Include information about specification dependencies (default: true)',
            default: true
          },
          format: {
            type: 'string',
            enum: ['detailed', 'summary', 'agent_ready'],
            description: 'Response format - agent_ready provides structured JSON for AI agents',
            default: 'agent_ready'
          }
        },

• src/index.ts:104-105 (registration)

  Registration in the MCP server's CallToolRequest handler: dispatches execution to the tool instance based on name.

  case 'get_specification_details':
    return await this.detailsTool.execute(args as unknown as GetSpecificationDetailsArgs);

• src/index.ts:79-79 (registration)

  Instantiation of the GetSpecificationDetailsTool instance with APIManager dependency.

  this.detailsTool = new GetSpecificationDetailsTool(this.apiManager);

• src/index.ts:88-89 (registration)

  Tool definition included in the ListTools response for MCP server discovery.

  this.searchTool.getDefinition(),
  this.detailsTool.getDefinition(),

• src/tools/get-specification-details.ts:102-159 (helper)

  Primary helper for formatting output in 'agent_ready' mode: structures specification metadata, working group info, release details, dependencies, content sections, and implementation guidance into JSON.

  private formatForAgent(details: any, args: GetSpecificationDetailsArgs): any {
