# Skill: CI Integration
**Domain:** CI/CD accessibility pipeline configuration
**Agents that use this skill:** `ci-accessibility`, `web-accessibility-wizard`, `accessibility-lead`
---
## Purpose
Patterns, templates, and reference data for integrating automated accessibility scanning into CI/CD pipelines. Covers axe-core CLI, Lighthouse CI, SARIF output, baseline management, and multi-platform configuration.
---
## axe-core CLI Reference
### Installation
```bash
npm install --save-dev @axe-core/cli
```
### WCAG 2.2 AA Tag Set
```bash
npx axe <url> --tags wcag2a,wcag2aa,wcag21a,wcag21aa,wcag22aa
```
### Output Formats
| Flag | Output |
|------|--------|
| `--reporter json` | JSON results to stdout |
| `--reporter sarif` | SARIF format for code scanning |
| `--reporter html` | Human-readable HTML report |
| `--save <file>` | Save results to file |
### Exit Codes
| Code | Meaning |
|------|---------|
| 0 | No violations found |
| 1 | Violations found |
| 2 | Error running scan |
---
## Baseline Pattern
### Purpose
Without a baseline, every legacy violation fails CI, making adoption impossible on brownfield apps. With a baseline, CI gates only prevent regressions.
### Baseline File Schema (`axe-baseline.json`)
```json
{
"version": "1.0",
"timestamp": "2026-03-22T00:00:00Z",
"tool": "@axe-core/cli",
"tags": "wcag2a,wcag2aa,wcag21a,wcag21aa,wcag22aa",
"violations": {
"color-contrast": { "count": 12, "pages": ["index.html", "about.html"] },
"image-alt": { "count": 3, "pages": ["gallery.html"] },
"label": { "count": 5, "pages": ["contact.html", "signup.html"] }
},
"total": 20
}
```
### Comparison Logic
```text
current_violations = run_axe_scan()
baseline = load("axe-baseline.json")
new_violations = current_violations - baseline
if new_violations.count > 0:
FAIL PR — "N new accessibility violations introduced"
else:
PASS — "No new violations (M existing in baseline)"
```
---
## GitHub Actions Template
```yaml
name: Accessibility Check
on:
pull_request:
paths: ['**/*.html', '**/*.jsx', '**/*.tsx', '**/*.vue', '**/*.svelte']
jobs:
a11y:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with: { node-version: 22 }
- run: npm ci
- run: npx axe $(git diff --name-only HEAD~1 --diff-filter=ACMR -- '*.html' | tr '\n' ' ') --tags wcag2a,wcag2aa,wcag21a,wcag21aa,wcag22aa --reporter json --save results.json
- name: Check results
run: |
violations=$(jq '[.[].violations[]] | length' results.json)
echo "Found $violations violations"
if [ "$violations" -gt 0 ]; then exit 1; fi
```
---
## SARIF Integration
SARIF (Static Analysis Results Interchange Format) enables inline annotations in GitHub PR diffs.
### Upload Step
```yaml
- uses: github/codeql-action/upload-sarif@v3
with:
sarif_file: results.sarif
category: accessibility
```
### Benefits
- Violations appear as inline annotations on the exact lines in the PR diff
- Results visible in the Security → Code Scanning tab
- Tracks violation trends over time
- Supports dismissal workflow for false positives
---
## Gating Strategies
| Strategy | Blocks On | Best For |
|----------|-----------|----------|
| **Strict** | Any violation (all severities) | New greenfield projects |
| **Standard** | Critical + Serious only | Active projects with good a11y baseline |
| **Baseline** | New violations only (regression) | Brownfield adoption, legacy codebases |
| **Warning** | Never blocks, comments only | Awareness phase, gradual adoption |
---
## Multi-Platform Templates
### Azure DevOps
```yaml
trigger:
paths:
include: ['**/*.html', '**/*.jsx', '**/*.tsx']
pool:
vmImage: 'ubuntu-latest'
steps:
- task: NodeTool@0
inputs: { versionSpec: '22.x' }
- script: npm ci && npx axe $(Build.SourcesDirectory)/index.html --tags wcag2a,wcag2aa
displayName: 'Accessibility Scan'
```
### GitLab CI
```yaml
accessibility:
image: node:22
script:
- npm ci
- npx axe $CI_PROJECT_DIR/index.html --tags wcag2a,wcag2aa
only:
changes: ['**/*.html', '**/*.jsx', '**/*.tsx']
```

## Severity Mapping
| axe-core Impact | CI Priority | Action |
|----------------|-------------|--------|
| critical | p1-blocker | Must block merge |
| serious | p2-high | Should block merge |
| moderate | p3-medium | Warn in PR comment |
| minor | p4-low | Info only |
