Posting Logic

Simple Post

gh pr comment $PR_NUMBER --body "$COMMENT_BODY"

Update Existing (Recommended)

Prevents comment spam on re-runs by updating existing comment:

# Marker includes persona ID to allow multiple persona comments
MARKER="<!-- user-test-results:$PERSONA_ID -->"

# Check for existing comment with this marker
EXISTING=$(gh pr view $PR_NUMBER --json comments \
  --jq ".comments[] | select(.body | contains(\"$MARKER\")) | .databaseId" \
  | head -1)

if [ -n "$EXISTING" ]; then
  # Update existing comment
  gh api repos/{owner}/{repo}/issues/comments/$EXISTING \
    -X PATCH \
    -f body="$COMMENT_BODY"
  echo "Updated existing comment"
else
  # Create new comment
  gh pr comment $PR_NUMBER --body "$COMMENT_BODY"
  echo "Created new comment"
fi

Multi-Persona Support

When running --personas with --pr:

• Each persona gets its own comment (separate markers)
• Or: Single combined comment with all results

GitHub Actions Integration

Basic Workflow

name: User Testing
on:
  pull_request:
    types: [opened, synchronize]

jobs:
  user-test:
    runs-on: ubuntu-latest
    permissions:
      pull-requests: write
    steps:
      - uses: actions/checkout@v4

      - name: Deploy Preview
        id: deploy
        run: |
          # Your preview deployment logic
          echo "url=https://preview-${{ github.event.pull_request.number }}.example.com" >> $GITHUB_OUTPUT

      - name: Install Claude Code
        run: npm install -g @anthropic-ai/claude-code

      - name: Run User Tests
        env:
          ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
        run: |
          claude --chrome "/user-test \
            --url ${{ steps.deploy.outputs.url }} \
            --persona genz-digital-native \
            --quiet \
            --pr ${{ github.event.pull_request.number }}"

With Recording

      - name: Run User Tests with Recording
        run: |
          claude --chrome "/user-test \
            --url ${{ steps.deploy.outputs.url }} \
            --persona boomer-tech-averse \
            --quiet \
            --record \
            --pr ${{ github.event.pull_request.number }}"

      - name: Upload Trace
        uses: actions/upload-artifact@v4
        with:
          name: playwright-trace
          path: "*.trace.zip"

Multi-Persona Testing

      - name: Run Multi-Persona Tests
        run: |
          claude --chrome "/user-test \
            --url ${{ steps.deploy.outputs.url }} \
            --personas 'boomer-tech-averse,genz-digital-native,screen-reader-user' \
            --quiet \
            --pr ${{ github.event.pull_request.number }}"

Error Handling

gh CLI Not Found

Error: gh CLI not installed
Skipping PR comment (results still output to stdout)

Authentication Failed

Error: gh CLI not authenticated
Run 'gh auth login' or ensure GITHUB_TOKEN is set
Skipping PR comment (results still output to stdout)

PR Not Found

Error: PR #123 not found
Verify PR number and repository access
Skipping PR comment (results still output to stdout)

Best Practices

1. Always use --quiet: Reduces noise, focuses on results
2. Combine with --record: Provides trace files for debugging
3. Use specific personas: Match persona to PR type (accessibility PR = screen-reader-user)
4. Update vs spam: The marker system prevents duplicate comments
5. Include viewport/network: Mobile PRs should test mobile viewport

Limitations

1. No inline images: GitHub doesn't support image uploads via API - link to artifacts instead
2. Comment size limit: ~65KB max - use collapsible sections
3. Rate limits: 5000 requests/hour with token
4. Requires gh CLI: Standard in GitHub Actions, may need install elsewhere
