• src/tools/reset-progress.ts:6-26 (handler)

  The `registerResetProgress` function registers the `reset_progress` tool on the MCP server and contains the logic that deletes all user-specific progress from the database.

  export function registerResetProgress(server: McpServer, db: Database.Database, userConfig: UserConfig): void {
    server.tool(
      'reset_progress',
      'WARNING: Permanently deletes ALL your study progress including answers, mastery data, and review schedules. This cannot be undone.',
      { confirmed: z.boolean().describe('Must be true to confirm the reset') },
      async ({ confirmed }) => {
        if (!confirmed) {
          return { content: [{ type: 'text' as const, text: 'Reset cancelled. Your progress is safe.' }] };
        }
        const userId = userConfig.userId;
        db.prepare('DELETE FROM answers WHERE userId = ?').run(userId);
        db.prepare('DELETE FROM domain_mastery WHERE userId = ?').run(userId);
        db.prepare('DELETE FROM review_schedule WHERE userId = ?').run(userId);
        db.prepare('DELETE FROM session_state WHERE userId = ?').run(userId);
        db.prepare('DELETE FROM study_sessions WHERE userId = ?').run(userId);
        db.prepare('DELETE FROM handout_views WHERE userId = ?').run(userId);
        db.prepare('DELETE FROM exam_attempts WHERE userId = ?').run(userId);
  
        return { content: [{ type: 'text' as const, text: 'All progress has been reset, including exam history. You can start fresh with start_assessment.' }] };
      }
    );
