Broker Portfolio Enhancements Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) for syntax tracking.

Goal: Add cursor-based pagination for broker positions, shimmer skeleton loading, and instrument name display in operations.

Architecture: Backend extracts positions from portfolio into a new paginated GET /positions endpoint. Frontend gets a useBrokerPositions hook, SkeletonBlock/TableSkeleton components, and shimmer CSS animations. The name field from T-Bank's OperationItem is mapped through to the frontend.

Tech Stack: NestJS (backend), React 18 + TanStack Query v5 (frontend), CSS custom properties

Task 1: Backend — Types and DTOs for positions page + operation name

Files:

Modify: apps/backend/src/modules/tbank/types/broker.types.ts
Create: apps/backend/src/modules/tbank/dto/broker-position-response.dto.ts
Create: apps/backend/src/modules/tbank/dto/broker-positions-page-response.dto.ts
Modify: apps/backend/src/modules/tbank/dto/broker-portfolio-response.dto.ts
Modify: apps/backend/src/modules/tbank/dto/broker-operation-response.dto.ts
Modify: apps/backend/src/modules/tbank/dto/broker-envelope.dto.ts
Step 1: Remove positions from BrokerPortfolio type, add BrokerPositionsPage, add name to BrokerOperation

Edit apps/backend/src/modules/tbank/types/broker.types.ts:

Remove positions: BrokerPosition[] from BrokerPortfolio.

Add after BrokerPosition type:

export type BrokerPositionsPage = {
  accountId: string;
  items: BrokerPosition[];
  nextCursor: string | null;
  hasNext: boolean;
  asOf: string;
};

Add name to BrokerOperation:

export type BrokerOperation = {
  cursor: string | null;
  accountId: string;
  id: string | null;
  parentOperationId: string | null;
  date: string | null;
  type: string;
  category: BrokerOperationCategory;
  description: string | null;
  name: string | null;
  state: string | null;
  instrumentUid: string | null;
  figi: string | null;
  ticker: string | null;
  classCode: string | null;
  instrumentType: string | null;
  payment: BrokerMoney | null;
  price: BrokerMoney | null;
  commission: BrokerMoney | null;
  yield: BrokerMoney | null;
  accruedInt: BrokerMoney | null;
  quantity: number | null;
  quantityDone: number | null;
};

Step 2: Create BrokerPositionResponseDto (extracted from portfolio DTO)

Create apps/backend/src/modules/tbank/dto/broker-position-response.dto.ts:

import { ApiProperty } from '@nestjs/swagger';
import { BrokerMoneyDto } from './broker-money.dto';

export class BrokerPositionResponseDto {
  @ApiProperty({ nullable: true })
  figi!: string | null;

  @ApiProperty({ nullable: true })
  instrumentUid!: string | null;

  @ApiProperty({ nullable: true })
  positionUid!: string | null;

  @ApiProperty({ nullable: true })
  ticker!: string | null;

  @ApiProperty({ nullable: true })
  classCode!: string | null;

  @ApiProperty({ nullable: true })
  instrumentType!: string | null;

  @ApiProperty({ nullable: true })
  name!: string | null;

  @ApiProperty({ nullable: true })
  quantity!: number | null;

  @ApiProperty({ nullable: true })
  blockedLots!: number | null;

  @ApiProperty({ type: BrokerMoneyDto, nullable: true })
  currentPrice!: BrokerMoneyDto | null;

  @ApiProperty({ type: BrokerMoneyDto, nullable: true })
  currentValue!: BrokerMoneyDto | null;

  @ApiProperty({ type: BrokerMoneyDto, nullable: true })
  averagePositionPrice!: BrokerMoneyDto | null;

  @ApiProperty({ nullable: true })
  expectedYieldPercent!: number | null;

  @ApiProperty({ type: BrokerMoneyDto, nullable: true })
  dailyYield!: BrokerMoneyDto | null;
}

Step 3: Create BrokerPositionsPageResponseDto

Create apps/backend/src/modules/tbank/dto/broker-positions-page-response.dto.ts:

import { ApiProperty } from '@nestjs/swagger';
import { BrokerPositionResponseDto } from './broker-position-response.dto';

export class BrokerPositionsPageResponseDto {
  @ApiProperty()
  accountId!: string;

  @ApiProperty({ type: [BrokerPositionResponseDto] })
  items!: BrokerPositionResponseDto[];

  @ApiProperty({ nullable: true })
  nextCursor!: string | null;

  @ApiProperty()
  hasNext!: boolean;

  @ApiProperty()
  asOf!: string;
}

Step 4: Remove positions from BrokerPortfolioResponseDto

Edit apps/backend/src/modules/tbank/dto/broker-portfolio-response.dto.ts:

Remove the import of BrokerPositionResponseDto (no longer needed here since BrokerPositionResponseDto is now in its own file).

Remove the entire BrokerPositionResponseDto class.

Remove the positions property from BrokerPortfolioResponseDto:

export class BrokerPortfolioResponseDto {
  @ApiProperty({ type: BrokerAccountResponseDto })
  account!: BrokerAccountResponseDto;

  @ApiProperty({ type: BrokerPortfolioTotalsDto })
  totals!: BrokerPortfolioTotalsDto;

  @ApiProperty({ type: BrokerPortfolioYieldsDto })
  yields!: BrokerPortfolioYieldsDto;

  @ApiProperty({ type: [BrokerMoneyDto] })
  cash!: BrokerMoneyDto[];

  @ApiProperty({ type: [BrokerMoneyDto] })
  blockedCash!: BrokerMoneyDto[];

  @ApiProperty()
  asOf!: string;
}

Step 5: Add name to BrokerOperationResponseDto

Edit apps/backend/src/modules/tbank/dto/broker-operation-response.dto.ts:

Add after description:

  @ApiProperty({ nullable: true })
  name!: string | null;

Step 6: Add BrokerPositionsEnvelopeDto to envelope

Edit apps/backend/src/modules/tbank/dto/broker-envelope.dto.ts:

Add import:

import { BrokerPositionsPageResponseDto } from './broker-positions-page-response.dto';

Add after BrokerOperationsEnvelopeDto:

export class BrokerPositionsEnvelopeDto {
  @ApiProperty({ type: BrokerPositionsPageResponseDto })
  data!: BrokerPositionsPageResponseDto;

  @ApiProperty({ type: BrokerResponseMetaDto })
  meta!: BrokerResponseMetaDto;
}

Step 7: Commit

Task 2: Backend — Mappers (separate positions, add name to operations)

Files:

Modify: apps/backend/src/modules/tbank/mappers/portfolio.mapper.ts
Modify: apps/backend/src/modules/tbank/mappers/operation.mapper.ts
Step 1: Extract mapBrokerPosition from mapBrokerPortfolio, remove positions from portfolio mapping

Edit apps/backend/src/modules/tbank/mappers/portfolio.mapper.ts:

Replace the file content with:

import type {

  let startIndex = 0;
  if (input.cursor) {
    const found = allPositions.findIndex(

  return {
    accountId: input.accountId,
    items: pageItems,
    nextCursor,
    hasNext,
    asOf: new Date().toISOString(),
  };
}

Step 2: Add name to mapOperation

Edit apps/backend/src/modules/tbank/mappers/operation.mapper.ts:

Add name: item.name ?? null, after the description line in the mapOperation return object (line 110):

    description: item.description || item.name || null,
    name: item.name ?? null,

Step 3: Commit

git add apps/backend/src/modules/tbank/mappers/portfolio.mapper.ts \
  apps/backend/src/modules/tbank/mappers/operation.mapper.ts
git commit -m "feat(tbank): extract mapBrokerPosition, add mapBrokerPositionsPage, add name to operation"

Task 3: Backend — BrokerPortfolioService with getPositions()

Files:

Modify: apps/backend/src/modules/tbank/services/broker-portfolio.service.ts
Step 1: Add getPositions() method, remove positions from getPortfolio

Edit apps/backend/src/modules/tbank/services/broker-portfolio.service.ts:

Add import for BrokerPositionsPage:

import type { BrokerPortfolio, BrokerPositionsPage } from '../types/broker.types';

Replace the file content to:

Keep getPortfolio() but remove positions from the mapped result (just don't include them — the mapper no longer returns them)
Add getPositions() method

Task 4: Backend — Controller + Envelope + Config for positions endpoint

Files:

Modify: apps/backend/src/modules/tbank/tbank.controller.ts
Modify: apps/backend/src/config/configuration.ts
Step 1: Add GET /accounts/:accountId/positions endpoint

Edit apps/backend/src/modules/tbank/tbank.controller.ts:

Add imports:

import { BrokerPositionsEnvelopeDto } from './dto/broker-envelope.dto';
import { BrokerPositionQueryDto } from './dto/broker-position-query.dto';

Add after getPortfolio method:

  @Get('accounts/:accountId/positions')
  @ApiOperation({ summary: 'Get paginated T-Bank broker account positions' })
  @ApiOkResponse({ type: BrokerPositionsEnvelopeDto })
  async getPositions(
    @Param('accountId') accountId: string,

  @Type(() => Number)
  @IsNumber()
  @Min(1)
  @Max(100)
  limit?: number = 10;
}

Step 3: Add tbankPositionsTtl to configuration

Edit apps/backend/src/config/configuration.ts:

Add after tbankOperationsTtl (line 34):

    tbankPositionsTtl: parseInt(process.env.CACHE_TBANK_POSITIONS_TTL || '60', 10),

Step 4: Commit

git add apps/backend/src/modules/tbank/tbank.controller.ts \

Step 2: Run tests

npx vitest run apps/backend/src/modules/tbank/services/broker-portfolio.service.spec.ts -w apps/backend

Expected: ALL PASS

Step 3: Add tbankPositionsTtl to tbank config test

Edit apps/backend/src/modules/tbank/tbank.config.spec.ts:

Add to the first it block after line 23:

    expect(config.cache.tbankPositionsTtl).toBe(60);

Add to the second it block — set env and assert:

    process.env.CACHE_TBANK_POSITIONS_TTL = '45';

And add assertion:

    expect(config.cache.tbankPositionsTtl).toBe(45);

Step 4: Run config tests

npx vitest run apps/backend/src/modules/tbank/tbank.config.spec.ts -w apps/backend

Expected: ALL PASS

Step 5: Commit

git add apps/backend/src/modules/tbank/services/broker-portfolio.service.spec.ts \
  apps/backend/src/modules/tbank/tbank.config.spec.ts
git commit -m "test(tbank): update portfolio tests, add getPositions tests"

Task 6: Frontend — CSS shimmer animations

Files:

Modify: apps/frontend/src/styles.css
Step 1: Add shimmer keyframes and skeleton class

Append to apps/frontend/src/styles.css:

@keyframes shimmer {
  0% { background-position: 200% 0; }
  100% { background-position: -200% 0; }
}

.skeleton {
  background: linear-gradient(
    90deg,
    var(--color-bg) 25%,
    #f0f0f0 50%,
    var(--color-bg) 75%
  );
  background-size: 200% 100%;
  animation: shimmer 1.5s ease-in-out infinite;
  border-radius: 4px;
}

Step 2: Commit

git add apps/frontend/src/styles.css
git commit -m "feat(frontend): add shimmer animation and .skeleton CSS class"

Task 7: Frontend — Types, API, and hooks

Files:

Create: apps/frontend/src/hooks/useBrokerPositions.ts
Modify: apps/frontend/src/api/responses.ts
Modify: apps/frontend/src/api/broker.ts
Modify: apps/frontend/src/api/broker.test.ts
Step 1: Update frontend types

Edit apps/frontend/src/api/responses.ts:

Remove positions: BrokerPosition[] from BrokerPortfolio.

Add after BrokerOperationsPage:

export interface BrokerPositionsPage {
  accountId: string;
  items: BrokerPosition[];
  nextCursor: string | null;
  hasNext: boolean;
  asOf: string;
}

Add name: string | null to BrokerOperation (after description):

  description: string | null;
  name: string | null;

Step 2: Add getBrokerPositions API function

Edit apps/frontend/src/api/broker.ts:

Add import:

import type {
  ApiResponseMeta,
  BrokerAccount,
  BrokerOperationsPage,
  BrokerPortfolio,
  BrokerPositionsPage,
} from './responses';

Add after getBrokerOperations:

export function getBrokerPositions(
  accountId: string,
  query: { cursor?: string; limit?: number } = {},
): Promise<{ data: BrokerPositionsPage; meta: ApiResponseMeta }> {
  return request<BrokerPositionsPage>(
    `/api/v1/broker/accounts/${encodeURIComponent(accountId)}/positions`,
    {
      cursor: query.cursor,
      limit: query.limit ? String(query.limit) : undefined,
    },
  );
}

Step 3: Update broker.test.ts — add positions test

Edit apps/frontend/src/api/broker.test.ts:

Replace the file:

import { afterEach, describe, expect, it, vi } from 'vitest';
import { getBrokerOperations, getBrokerPositions } from './broker';

describe('broker api', () => {
  afterEach(() => {
    vi.restoreAllMocks();
  });

  it('serializes operations query parameters', async () => {
    vi.spyOn(globalThis, 'fetch').mockResolvedValue({
      ok: true,
      json: async () => ({
        data: {
          data: { accountId: 'acc-1', items: [], nextCursor: null, hasNext: false, asOf: 'now' },
          meta: { fromCache: false, cachedAt: null },
        },
      }),
    } as Response);

    await getBrokerOperations('acc-1', { cursor: 'c1', limit: 50 });

    expect(fetch).toHaveBeenCalledWith(
      expect.stringContaining('/api/v1/broker/accounts/acc-1/operations?cursor=c1&limit=50'),
      expect.any(Object),
    );
  });

  it('serializes positions query parameters', async () => {
    vi.spyOn(globalThis, 'fetch').mockResolvedValue({
      ok: true,
      json: async () => ({
        data: {
          data: { accountId: 'acc-1', items: [], nextCursor: null, hasNext: false, asOf: 'now' },
          meta: { fromCache: false, cachedAt: null },
        },
      }),
    } as Response);

    await getBrokerPositions('acc-1', { cursor: 'pos-1', limit: 5 });

    expect(fetch).toHaveBeenCalledWith(
      expect.stringContaining('/api/v1/broker/accounts/acc-1/positions?cursor=pos-1&limit=5'),
      expect.any(Object),
    );
  });
});

Step 4: Create useBrokerPositions hook

Create apps/frontend/src/hooks/useBrokerPositions.ts:

import { keepPreviousData, useQuery } from '@tanstack/react-query';
import { getBrokerPositions } from '../api/broker';
import type { BrokerPositionsPage } from '../api/responses';

export function useBrokerPositions(
  accountId: string | undefined,
  query: { cursor?: string; limit?: number } = {},
) {
  return useQuery<BrokerPositionsPage>({
    queryKey: ['broker', 'positions', accountId, query],
    enabled: Boolean(accountId),
    queryFn: async () => (await getBrokerPositions(accountId!, query)).data,
    staleTime: 60_000,
    retry: 2,
    placeholderData: keepPreviousData,
    refetchOnWindowFocus: false,
  });
}

Step 5: Commit

git add apps/frontend/src/api/responses.ts \
  apps/frontend/src/api/broker.ts \
  apps/frontend/src/api/broker.test.ts \
  apps/frontend/src/hooks/useBrokerPositions.ts
git commit -m "feat(frontend): add BrokerPositionsPage types, API, and hook"

Task 8: Frontend — SkeletonBlock and TableSkeleton components

Files:

Create: apps/frontend/src/components/SkeletonBlock.tsx
Create: apps/frontend/src/components/TableSkeleton.tsx
Step 1: Create SkeletonBlock

Create apps/frontend/src/components/SkeletonBlock.tsx:

export function SkeletonBlock({ width, height, borderRadius = 4 }: {
  width?: string | number;
  height?: string | number;
  borderRadius?: number;
}) {
  return (
    <div
      className="skeleton"
      style={{
        width: width ?? '100%',
        height: height ?? 16,
        borderRadius,
      }}
    />
  );
}

Step 2: Create TableSkeleton

Create apps/frontend/src/components/TableSkeleton.tsx:

import { SkeletonBlock } from './SkeletonBlock';

const tdStyle = {
  borderBottom: '1px solid #eeeeee',
  padding: '10px 8px',
  verticalAlign: 'top',
} satisfies React.CSSProperties;

type Column = { width: string };

export function TableSkeleton({ rows = 5, columns }: { rows?: number; columns: Column[] }) {
  return (
    <tbody>
      {Array.from({ length: rows }).map((_, i) => (
        <tr key={i}>
          {columns.map((col, j) => (
            <td key={j} style={tdStyle}>
              <SkeletonBlock height={12} width={col.width} />
            </td>
          ))}
        </tr>
      ))}
    </tbody>
  );
}

Step 3: Commit

git add apps/frontend/src/components/SkeletonBlock.tsx \
  apps/frontend/src/components/TableSkeleton.tsx
git commit -m "feat(frontend): add SkeletonBlock and TableSkeleton components"

Task 10: Frontend — BrokerOperationsTable with shimmer + instrument name

Files:

Modify: apps/frontend/src/pages/broker/BrokerOperationsTable.tsx
Step 1: Add shimmer loading and instrument name display

Edit apps/frontend/src/pages/broker/BrokerOperationsTable.tsx:

Add import:

import { TableSkeleton } from '../../components/TableSkeleton';

Replace OperationInstrument:

function OperationInstrument({ operation }: { operation: BrokerOperation }) {
  const ticker = operation.ticker || operation.description || '-';
  const path = getBrokerInstrumentPath({
    ticker: operation.ticker,
    instrumentType: operation.instrumentType,
    classCode: operation.classCode,
  });
  const name = operation.name || operation.description;

  if (!path && !name) return <span>-</span>;
  if (!path) return <span>{name}</span>;
  if (!ticker || ticker === '-') return <Link to={path}>{name}</Link>;

  return (
    <div style={{ display: 'grid', gap: 2 }}>
      <Link to={path} style={{ fontWeight: 700 }}>{ticker}</Link>
      {name && name !== ticker && (
        <span style={{ color: 'var(--color-text-secondary)', fontSize: 12 }}>{name}</span>
      )}
    </div>
  );
}

Replace the isLoading check block (lines 147-195):

Keep the same structure but replace the loading state:

      {isLoading ? (
        <div style={{ overflowX: 'auto', background: 'var(--color-surface)' }}>
          <table style={tableStyle}>
            <thead>
              <tr>
                <th align="left" style={thStyle}>Дата</th>
                <th align="left" style={thStyle}>Тип</th>
                <th align="left" style={thStyle}>Инструмент</th>
                <th align="right" style={thStyle}>Сумма</th>
              </tr>
            </thead>
            <TableSkeleton rows={5} columns={[

Task 13: Frontend — Update BrokerPages tests

Files:

Modify: apps/frontend/src/pages/broker/BrokerPages.test.tsx
Step 1: Update tests — remove positions from portfolio mock, add positions hook mock

Edit apps/frontend/src/pages/broker/BrokerPages.test.tsx:

Add import:

import * as positionsHook from '../../hooks/useBrokerPositions';

Update the portfolio mock in "renders positions and operations for account detail" (line 54-91):

Remove positions from the portfolio data mock:

    vi.spyOn(portfolioHook, 'useBrokerPortfolio').mockReturnValue({
      data: {
        account: {
          id: 'acc-1',
          type: 'brokerage',
          name: 'Broker',
          status: 'ACCOUNT_STATUS_OPEN',
          openedAt: null,
          accessLevel: null,
        },
        totals: { portfolio: { currency: 'RUB', units: '1000', nano: 0, value: 1000 } },
        yields: { expectedPercent: 5, daily: null, dailyPercent: null },
        cash: [{ currency: 'RUB', units: '100', nano: 0, value: 100 }],
        blockedCash: [],
        asOf: '2026-06-16T00:00:00.000Z',
      },
      isLoading: false,
      error: null,
    } as any);

Add positions mock:

    vi.spyOn(positionsHook, 'useBrokerPositions').mockReturnValue({
      data: {
        accountId: 'acc-1',
        items: [
          {
            figi: null,
            instrumentUid: 'uid-1',
            positionUid: null,
            ticker: 'SBER',
            classCode: 'TQBR',
            instrumentType: 'share',
            name: 'Sberbank',
            quantity: 10,
            blockedLots: null,
            currentPrice: null,
            currentValue: { currency: 'RUB', units: '1000', nano: 0, value: 1000 },
            averagePositionPrice: null,
            expectedYieldPercent: null,
            dailyYield: null,
          },
        ],
        nextCursor: null,
        hasNext: false,
        asOf: '2026-06-16T00:00:00.000Z',
      },
      isLoading: false,
      error: null,
    } as any);

Repeat for the other tests:

"renders broker positions as separate linked stock and bond tables" (line 139): remove positions from portfolio mock, add positions hook mock
"renders broker operations with Russian labels" (line 225): remove positions from portfolio mock, add positions hook mock
"requests broker operations by cursor" (line 321): remove positions from portfolio mock, add positions hook mock

For the table test (line 139), add a richer positions mock:

    vi.spyOn(positionsHook, 'useBrokerPositions').mockReturnValue({
      data: {
        accountId: 'acc-1',
        items: [
          {
            figi: null,
            instrumentUid: 'share-uid',
            positionUid: null,
            ticker: 'SBER',
            classCode: 'TQBR',
            instrumentType: 'share',
            name: 'Sberbank',
            quantity: 10,
            blockedLots: null,
            currentPrice: { currency: 'RUB', units: '250', nano: 0, value: 250 },
            currentValue: { currency: 'RUB', units: '2500', nano: 0, value: 2500 },
            averagePositionPrice: null,
            expectedYieldPercent: 20,
            dailyYield: null,
          },
          {
            figi: null,
            instrumentUid: 'bond-uid',
            positionUid: null,
            ticker: 'SU26238RMFS5',
            classCode: 'TQOB',
            instrumentType: 'bond',
            name: 'ОФЗ 26238',
            quantity: 2,
            blockedLots: null,
            currentPrice: { currency: 'RUB', units: '900', nano: 0, value: 900 },
            currentValue: { currency: 'RUB', units: '1800', nano: 0, value: 1800 },
            averagePositionPrice: null,
            expectedYieldPercent: 10,
            dailyYield: null,
          },
        ],
        nextCursor: null,
        hasNext: false,
        asOf: '2026-06-17T00:00:00.000Z',
      },
      isLoading: false,
      error: null,
    } as any);

For the two operation tests (line 225 and 321), provide empty positions list:

    vi.spyOn(positionsHook, 'useBrokerPositions').mockReturnValue({
      data: {
        accountId: 'acc-1',
        items: [],
        nextCursor: null,
        hasNext: false,
        asOf: '2026-06-17T00:00:00.000Z',
      },
      isLoading: false,
      error: null,
    } as any);
