Docs-as-Code Skill

When to Use This Skill

Use this skill when:

Docs As Code tasks - Working on documentation pipeline automation and docs-as-code workflows
Planning or design - Need guidance on Docs As Code approaches
Best practices - Want to follow established patterns and standards

Overview

Implement documentation-as-code workflows with automated pipelines, version control, and CI/CD integration.

MANDATORY: Documentation-First Approach

Before implementing docs-as-code:

Invoke docs-management skill for documentation patterns
Verify tooling versions via MCP servers (context7 for docusaurus/mkdocs)
Base guidance on current best practices

Docs-as-Code Philosophy

Docs-as-Code Principles:

┌─────────────────────────────────────────────────────────────────────────────┐
│  1. Version Control                                                          │
│     - Docs live alongside code in the same repository                        │
│     - Changes tracked with meaningful commit messages                        │
│     - Branch-based workflow for documentation updates                        │
├─────────────────────────────────────────────────────────────────────────────┤
│  2. Review Process                                                           │
│     - Pull requests for documentation changes                                │
│     - Technical review by subject matter experts                             │
│     - Style review by technical writers                                      │
├─────────────────────────────────────────────────────────────────────────────┤
│  3. Automated Testing                                                        │
│     - Linting for style and grammar                                          │
│     - Link validation                                                        │
│     - Build verification                                                     │
├─────────────────────────────────────────────────────────────────────────────┤
│  4. Continuous Deployment                                                    │
│     - Automatic publishing on merge                                          │
│     - Preview deployments for PRs                                            │
│     - Versioned documentation releases                                       │

Documentation Testing

Link Checking

// check-links.mjs
import { remark } from 'remark';
import remarkLintNoDeadUrls from 'remark-lint-no-dead-urls';
import { read } from 'to-vfile';
import { glob } from 'glob';
import { reporter } from 'vfile-reporter';

const files = await glob('docs/**/*.md');

for (const file of files) {
  const result = await remark()
    .use(remarkLintNoDeadUrls, {
      skipLocalhost: true,
      skipOffline: true,
    })
    .process(await read(file));

  console.error(reporter(result));
}

Screenshot Testing

// docs.spec.ts - Playwright screenshot tests
import { test, expect } from '@playwright/test';

test.describe('Documentation Screenshots', () => {
  test('homepage renders correctly', async ({ page }) => {
    await page.goto('/');
    await expect(page).toHaveScreenshot('homepage.png');
  });

  test('API reference page', async ({ page }) => {
    await page.goto('/docs/api/reference');
    await expect(page.locator('.api-content')).toBeVisible();
    await expect(page).toHaveScreenshot('api-reference.png');
  });

  test('dark mode toggle', async ({ page }) => {
    await page.goto('/');
    await page.click('[data-theme-toggle]');
    await expect(page).toHaveScreenshot('homepage-dark.png');
  });
});

Best Practices

Content Organization

Practice	Description
Single Source of Truth	Each concept documented in one place
Progressive Disclosure	Start simple, link to details
Consistent Structure	Same sections across similar pages
Clear Navigation	Logical hierarchy, breadcrumbs
Search Optimization	Good headings, keywords, descriptions

Writing Guidelines

Use active voice: "Configure the setting" not "The setting should be configured"
Be concise: Remove unnecessary words
Use examples: Show, don't just tell
Maintain consistency: Same terms throughout
Update regularly: Documentation rots quickly

Versioning Strategy

Documentation Versioning:

Option 1: Version Folders (Docusaurus/MkDocs mike)
├── docs/
│   ├── version-1.0/
│   ├── version-2.0/
│   └── current/

Option 2: Branch-based
├── main (current)
├── v1.x
└── v2.x

Option 3: Git Tags
├── v1.0.0
