Implementation Reference
- src/common/tools.ts:3-53 (handler)The core implementation of the 'group-text-by-json' tool handler. Parses the JSON template to extract keys and generates a structured prompt for an AI to group subsequent text input based on those keys.
const groupTextByJsonTool = (template: string) => { if (!template) { throw new Error("Both template and text are required"); } try { logger.info("Template:", template); let objectKeys: string[] = []; try { const templateObj = JSON.parse(template); objectKeys = deepObjectKeys(templateObj, true); } catch (parseError) { logger.error("Failed to parse template:", parseError); throw new Error(`Invalid template format: ${parseError}`); } const resultPrompt = ` You are a helpful assistant that groups text based on JSON keys. Here are the keys in the template: ${objectKeys.join(", ")}. Please group the text based on the keys. and give me the result in raw text. Don't give it in JSON format or object format. It should be in the following format: Format: <key>: <corresponding text found in the text> Here's an example: sentence: The MacBook Pro costs $2,499. result: brand: MacBook price: $2,499 description: The MacBook Pro is a powerful laptop with a Retina display. `; return { content: [ { type: "text", text: resultPrompt, }, ], }; } catch (error) { logger.error("Error processing template:", error); throw new Error(`Failed to process template: ${error}`); } }; - src/common/types.ts:3-5 (schema)Zod schema defining the input for the 'group-text-by-json' tool: a JSON template string.
const GroupTextByJsonSchema = z.object({ template: z.string().describe("JSON template with placeholders"), }); - src/index.ts:39-44 (registration)Registration of the tool in the ListToolsRequestHandler, including name, description, and input schema.
