Workflow Shell Control-Flow Refactoring Guide

         

Overview

This document tracks the refactoring of GitHub Actions workflows to fix shell control-flow errors. GitHub Actions does not allow multiline shell logic (if/for/while) directly in run: blocks.

Status

Overall: ✅ COMPLETE — All 9 workflows refactored and tested

PR: #1412 | Issue: #1413
Branch: fix/ci-unified-checks-validate-changed-files

Wave 1: Foundation Workflows ✅ (6 workflows)

1. ✅ CI • Unified Checks - Added path filters, removed merge_group from pr-template
2. ✅ validate-pr-template - Removed duplicate merge_group trigger, fixed template validation
3. ✅ validate-mermaid-pr - Fully disabled (consolidated to docs-validation.yml)
4. ✅ metrics-reporting - Fixed invalid cron syntax (0 6 ** 1 → 0 6 * * 1)
5. ✅ metadata-governance - Moved shell logic to .github/scripts/summarize-native-type.sh
6. ✅ changelog-management - Moved shell logic to .github/scripts/report-changelog-action.sh

Wave 2: Validation Workflows ✅ (4 workflows, 1 helper script)

1. docs-validation.yml (3 problematic steps)

Lines 47-82: Identify changed Markdown files

# Problem: multiline if/else in run block
# Solution: Use identify-changed-markdown.js
- name: Identify changed Markdown files
  id: changed
  env:
    EVENT_NAME: ${{ github.event_name }}
    BASE_SHA: ${{ github.event.pull_request.base.sha || github.event.before }}
    HEAD_SHA: ${{ github.event.pull_request.head.sha || github.sha }}
  run: node scripts/identify-changed-markdown.js >> "$GITHUB_OUTPUT"

Lines 84-96: Check for Mermaid diagrams

# Problem: for loop iterating over files
# Solution: Use check-mermaid-diagrams.sh
- name: Check for Mermaid diagrams in changed files
  id: has_diagrams
  if: steps.changed.outputs.has_changes == 'true'
  env:
    CHANGED_FILES: ${{ steps.changed.outputs.files }}
  run: bash .github/scripts/check-mermaid-diagrams.sh

Lines 124-140: Collect results

# Problem: multiline if logic for outcome aggregation
# Solution: Use collect-validation-results.js
- name: Collect results
  id: results
  if: steps.has_diagrams.outputs.result == 'true'
  env:
    SYNTAX_OUTCOME: ${{ steps.syntax.outcome }}
    A11Y_OUTCOME: ${{ steps.accessibility.outcome }}
    CONTRAST_OUTCOME: ${{ steps.contrast.outcome }}
  run: node scripts/collect-validation-results.js >> "$GITHUB_OUTPUT"

2. documentation.yml ✅ (2 steps)

Step: Check validation outcomes → scripts/collect-validation-results.js Step: Generate audit report → scripts/generate-doc-audit-report.js

Commits: ed68bf312

3. meta.yml ✅ (2 steps)

Step: Open or update automation PR → .github/scripts/handle-meta-agent-pr.js
Step: Lint changed Markdown → scripts/validate-markdown-lint.js

Commits: ed68bf312, d34280e94 (ES module syntax fix)

4. docs-validation.yml ✅ (3 steps)

Step: Identify changed Markdown files → scripts/identify-changed-markdown.js
Step: Check for Mermaid diagrams → .github/scripts/check-mermaid-diagrams.sh
Step: Collect results → scripts/collect-validation-results.js
Early exit logic → Added early exit when no markdown changes

Commits: ed68bf312, 21874dc3d

5. metrics-pipeline.yml ✅ (2 steps)

Step: Validate report structure → .github/scripts/validate-reports-structure.js
Step: Check for uppercase filenames → .github/scripts/validate-reports-structure.js

Refactoring Pattern

Before (❌ Invalid):

run: |
  if [ "${{ github.event_name }}" = "pull_request" ]; then
    # logic here
  else
    # other logic
  fi

After (✅ Valid):

run: node .github/scripts/my-helper.js
env:
  EVENT_NAME: ${{ github.event_name }}

Best Practices

1. Always use environment variables - Never pass complex values as command-line arguments
2. Use execFileSync - In Node.js scripts, prefer execFileSync over execSync for safety
3. One script per workflow operation - Keep scripts focused and testable
4. Add tests - Every helper script should have tests in .github/scripts/__tests__/
5. Document the purpose - Add comments explaining what the script does

Testing

All helper scripts have tests in .github/scripts/__tests__/workflow-helpers.test.js:

npm test -- .github/scripts/__tests__/workflow-helpers.test.js

Project Tracking

Phase 4: CI Workflows Shell Control-Flow Refactoring

• PR: #1412 - fix(ci): resolve CI - Unified Checks failures with workflow refactoring
• Issue: #1413 - Reciprocal tracking issue
• Related: #1392 - CodeQL workflow review (original trigger)
• Epic: #1227 - GitHub Workflows Consolidation Initiative
• Documentation: .github/projects/active/workflows-consolidation-2026-q3/PHASE_4_CI_WORKFLOWS_REFACTORING.md

Security Improvements

✅ Command Injection Prevention: All scripts use execFileSync with argument arrays instead of shell interpolation

✅ Environment Variable Safety: Configuration passed via env vars, not command-line arguments

✅ No Direct Shell Evaluation: No use of eval(), exec(), or backticks with user input

Completion Summary
