• index.js:719-721 (handler)

  Handler for matrix_daily_summary tool call. Dispatches to external Google Apps Script API via callAPI function with action 'matrixDailySummary' and tool arguments.

  case "matrix_daily_summary":
    result = await callAPI("matrixDailySummary", args);
    break;

• index.js:502-515 (schema)

  Input schema defining parameters for matrix_daily_summary: optional date (YYYY-MM-DD) and format (bullet, prose, slack).

  inputSchema: {
    type: "object",
    properties: {
      date: {
        type: "string",
        description: "Date in YYYY-MM-DD format (defaults to today)"
      },
      format: {
        type: "string",
        description: "Output format",
        enum: ["bullet", "prose", "slack"]
      }
    }
  }

• index.js:499-516 (registration)

  Registration of the matrix_daily_summary tool in the ListToolsRequestHandler response, including name, description, and input schema.

  {
    name: "matrix_daily_summary",
    description: "Generate formatted summary of Matrix entries for a specific date. Automatically parses timestamps, bug UIDs, time spent, and generates human-readable output.",
    inputSchema: {
      type: "object",
      properties: {
        date: {
          type: "string",
          description: "Date in YYYY-MM-DD format (defaults to today)"
        },
        format: {
          type: "string",
          description: "Output format",
          enum: ["bullet", "prose", "slack"]
        }
      }
    }
  },

• index.js:74-131 (helper)

  callAPI helper function that all proxied tools (including matrix_daily_summary) use to POST requests to the Google Apps Script backend URL with the action name and arguments as form data.

  async function callAPI(action, data = {}) {
    debugLog('=== API CALL START ===');
    debugLog(`Action: ${action}`);
    debugLog(`Data: ${JSON.stringify(data)}`);
  
    try {
      // Build form-encoded body for POST
      const formData = new URLSearchParams();
      formData.append('action', action);
  
      // Add all data fields to form
      for (const [key, value] of Object.entries(data)) {
        if (value !== undefined && value !== null) {
          formData.append(key, value.toString());
        }
      }
  
      const formString = formData.toString();
      debugLog(`FormData: ${formString}`);
      debugLog(`API_URL: ${API_URL}`);
  
      // Use POST with proper content type
      const response = await fetch(API_URL, {
        method: 'POST',
        headers: {
          'Content-Type': 'application/x-www-form-urlencoded',
        },
        body: formString
      });
  
      debugLog(`Response status: ${response.status}`);
      debugLog(`Response ok: ${response.ok}`);
  
      if (!response.ok) {
        debugLog(`Response not OK: ${response.status} ${response.statusText}`);
        throw new Error(`API request failed: ${response.status} ${response.statusText}`);
      }
  
      const text = await response.text();
      debugLog(`Response text length: ${text.length}`);
      debugLog(`Response text: ${text}`);
  
      if (!text) {
        debugLog('ERROR: Empty response from API');
        throw new Error('Empty response from API');
      }
  
      const parsed = JSON.parse(text);
      debugLog(`Parsed successfully: ${JSON.stringify(parsed)}`);
      debugLog('=== API CALL END ===');
      return parsed;
  
    } catch (error) {
      debugLog(`ERROR in callAPI: ${error.message}`);
      debugLog(`ERROR stack: ${error.stack}`);
      throw error;
    }
