First, summarize what it does, its dependencies, license status if identifiable, and any risks. Show the exact files you propose to add under .agents/skills/grammarly-ci-integration/. Do not write files or run scripts until I approve.

After I approve, install the complete skill folder, including required referenced files, into that project location. Verify it is discoverable, then tell me its actual invocation name and how to use it. Do not claim it is installed until you have verified it.

Grammarly CI Integration

Overview

Set up CI/CD for Grammarly text analysis integrations: run unit tests with mocked grammar check and suggestion responses on every PR, validate live API connectivity for text scoring on merge to main. Grammarly's Text API provides writing quality scores, grammar corrections, and tone detection, so CI pipelines verify content quality gates, documentation linting, and automated writing feedback workflows.

GitHub Actions Workflow

Mock-Based Unit Tests

// tests/grammarly-service.test.ts
import { describe, it, expect, vi } from 'vitest';
import { checkDocumentation } from '../src/grammarly-service';

vi.mock('../src/grammarly-client', () => ({
  GrammarlyClient: vi.fn().mockImplementation(() => ({
    checkText: vi.fn().mockResolvedValue({
      overall_score: 87,
      alerts: [
        { type: 'grammar', message: 'Subject-verb disagreement', offset: 12, length: 5, replacements: ['are'] },
        { type: 'clarity', message: 'Consider simplifying', offset: 45, length: 20, replacements: ['use'] },
      ],
      tone: { formal: 0.8, confident: 0.7 },
    }),
    getSuggestions: vi.fn().mockResolvedValue({
      suggestions: [{ text: 'Rephrase for clarity', category: 'engagement' }],
    }),
  })),
}));

describe('Grammarly Service', () => {
  it('checks documentation quality and returns score', async () => {
    const result = await checkDocumentation('The data is ready for review.');
    expect(result.overall_score).toBeGreaterThan(80);
    expect(result.alerts).toHaveLength(2);
  });
});

Integration Tests

// tests/integration/grammarly.integration.test.ts
import { describe, it, expect } from 'vitest';

const hasCredentials = !!process.env.GRAMMARLY_CLIENT_ID;

describe.skipIf(!hasCredentials)('Grammarly Live API', () => {
  it('analyzes text via Text API', async () => {
    const tokenRes = await fetch('https://api.grammarly.com/v1/oauth/token', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({
        client_id: process.env.GRAMMARLY_CLIENT_ID,
        client_secret: process.env.GRAMMARLY_CLIENT_SECRET,
        grant_type: 'client_credentials',
      }),
    });
    expect(tokenRes.status).toBe(200);
    const { access_token } = await tokenRes.json();
    expect(access_token).toBeDefined();
  });
});

Error Handling

CI Issue	Cause	Fix
`401 Unauthorized`	Invalid client credentials	Regenerate at developer.grammarly.com
OAuth token expired	Token TTL exceeded	Implement token refresh before each test run
Score below threshold	Content quality regression	Set minimum score in CI config (e.g., 75) and fix flagged alerts
Rate limit (429)	Too many text check requests	Batch text submissions and add throttling
Empty suggestions	Text too short for analysis	Ensure test inputs are at least 50 characters
