How to use tdd-workflows-tdd-red on Cursor

AI-first code editor with Composer

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your machine
›Node.js 16+ with npm — verify with node --version
›Active project directory where you want to add tdd-workflows-tdd-red

Run the install command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/sickn33/antigravity-awesome-skills --skill tdd-workflows-tdd-red

Fetches tdd-workflows-tdd-red from sickn33/antigravity-awesome-skills and configures it for Cursor.

Select Cursor when prompted

The CLI shows a list of agents. Use arrow keys and space to select Cursor:

◆ Which agents do you want to install to?

│

│ ── Universal (.agents/skills) ────────────────

│ · Cline · Codex · Goose · Windsurf

│ ●Cursor(selected)

│ · Cursor · Aider · Continue

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/tdd-workflows-tdd-red

Restart Cursor to activate tdd-workflows-tdd-red. Access via /tdd-workflows-tdd-red in your agent's command palette.

Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Use Cases

User Story & Requirements Generation

Create detailed user stories, acceptance criteria, and feature specs

Example

Generate user stories for 'password reset feature' with acceptance criteria, edge cases, and test scenarios

✓

Reduce spec writing time by 50%, ensure comprehensive coverage

Competitive Analysis

Research competitors, compare features, identify gaps

Example

Analyze 5 competitor products, create feature comparison matrix, suggest differentiation opportunities

✓

Complete competitive research in 2 hours instead of 2 days

Roadmap Prioritization

Evaluate features using frameworks (RICE, ICE, Kano) and create prioritized backlogs

Example

Score 20 feature ideas using RICE framework, generate prioritized roadmap with rationale

Core Requirements

Test Structure

Framework-appropriate setup (Jest/pytest/JUnit/Go/RSpec)
Arrange-Act-Assert pattern
should_X_when_Y naming convention
Isolated fixtures with no interdependencies

Behavior Coverage

Happy path scenarios
Edge cases (empty, null, boundary values)
Error handling and exceptions
Concurrent access (if applicable)

Failure Verification

Tests MUST fail when run
Failures for RIGHT reasons (not syntax/import errors)
Meaningful diagnostic error messages
No cascading failures

Test Categories

Unit: Isolated component behavior
Integration: Component interaction
Contract: API/interface contracts
Property: Mathematical invariants

Framework Patterns

JavaScript/TypeScript (Jest/Vitest)

Mock dependencies with vi.fn() or jest.fn()

Use @testing-library for React components

Property tests with fast-check

Python (pytest)

Fixtures with appropriate scopes

Parametrize for multiple test cases

Hypothesis for property-based tests

Table-driven tests with subtests

t.Parallel() for parallel execution

Use testify/assert for cleaner assertions

Ruby (RSpec)

let for lazy loading, let! for eager

Contexts for different scenarios

Shared examples for common behavior

Example (Minimal)

// auth.service.test.ts describe('AuthService', () => { let authService: AuthService; let mockUserRepo: jest.Mocked<UserRepository>; beforeEach(() => { mockUserRepo = { findByEmail: jest.fn() } as any; authService = new AuthService(mockUserRepo); }); it('should_return_token_when_valid_credentials', async () => { const user = { id: '1', email: '[email protected]', passwordHash: 'hashed' }; mockUserRepo.findByEmail.mockResolvedValue(user); const result = await authService.authenticate('[email protected]', 'pass'); expect(result.success).toBe(true); expect(result.token).toBeDefined(); }); it('should_fail_when_user_not_found', async () => { mockUserRepo.findByEmail.mockResolvedValue(null); const result = await authService.authenticate('[email protected]', 'pass'); expect(result.success).toBe(false); expect(result.error).toBe('INVALID_CREDENTIALS'); }); });
