This tool is useful when you need to analyze the structure of a design, understand component hierarchy, or extract design properties. You must provide a fileId and layerId to identify the specific design element. This tool returns the raw DSL data in JSON format that you can then parse and analyze. This tool also returns the rules you must follow when generating code. The DSL data can also be used to transform and generate code for different frameworks." `; export class GetDslTool extends BaseTool { name = DSL_TOOL_NAME; description = DSL_TOOL_DESCRIPTION; private httpUtil: HttpUtil; constructor(httpUtil: HttpUtil) { super(); this.httpUtil = httpUtil; } schema = z.object({ fileId: z .string() .describe( "MasterGo design file ID (format: file/<fileId> in MasterGo URL)" ), layerId: z .string() .describe( "Layer ID of the specific component or element to retrieve (format: ?layer_id=<layerId> / file=<fileId> in MasterGo URL)" ), }); async execute({ fileId, layerId }: z.infer<typeof this.schema>) { try { const dsl = await this.httpUtil.getDsl(fileId, layerId); return { content: [ { type: "text" as const, text: JSON.stringify(dsl), }, ], }; } catch (error) { return { content: [ { type: "text" as const, text: JSON.stringify({ error: "Failed to get DSL" }), }, ], }; } } }
