# TYPO3 Extension Conformance Checker

Evaluate TYPO3 extensions for standards compliance, architecture, and best practices.

## When to Use

- Assessing extension quality before production deployment
- Generating conformance reports for code review
- Planning modernization to TYPO3 v12/v13/v14 standards
- Validating TER publishing readiness

## Skill Delegation

- **Testing**: Delegate to `typo3-testing` skill
- **Documentation**: Delegate to `typo3-docs` skill
- **OpenSSF Scorecard**: Delegate to `enterprise-readiness` skill

## Evaluation Workflow

### Step 0: Understand Extension Context (always first)

Before checking files, understand: purpose, target TYPO3/PHP version, extension type (plugin, module, site package, library), criticality, and codebase scope.

### Steps 1-9: Conformance Checks

1. **Initial Assessment** -- Extension key, target TYPO3 version, extension type
2. **File Structure** -- composer.json, ext_emconf.php, required directories
3. **Coding Standards** -- strict_types, type declarations, PSR-12
4. **Prohibited Patterns** -- No `$GLOBALS` access, no `GeneralUtility::makeInstance()` for services
5. **PHP Architecture** -- Constructor DI, Services.yaml, PSR-14 events
6. **Backend Modules** -- ES6 modules, Modal API, CSRF protection (v13+)
7. **Testing** -- PHPUnit setup, Playwright E2E, coverage >70%
8. **Best Practices** -- DDEV setup, runTests.sh, quality tools, CI/CD
9. **TER Publishing** -- Workflow, upload comment format, CI compatibility

### Step 10: Verification Loop

After fixes, re-run checks. Document score improvement (e.g., "58 -> 82"). Ensure no regressions.

## Scoring System

**Base Score (0-100):** Architecture (20) + Guidelines (20) + PHP Patterns (20) + Testing (20) + Best Practices (20). Excellence bonus up to 22 additional points.

| Score Range | Interpretation | Action |
|------------|----------------|--------|
| 90-100+ | Excellent | Ready for production and TER |
| 80-89 | Good | Minor improvements recommended |
| 70-79 | Acceptable | Address before major releases |
| 50-69 | Needs Work | Significant improvements required |
| Below 50 | Critical | Block deployment until resolved |

**Critical issues** (security, data loss, core incompatibility) block deployment regardless of score.

## Running Checks

```bash
# Full conformance check
scripts/check-conformance.sh /path/to/extension

# Individual checks
scripts/check-file-structure.sh /path/to/extension
scripts/check-coding-standards.sh /path/to/extension
scripts/check-architecture.sh /path/to/extension
scripts/check-testing.sh /path/to/extension
scripts/check-phpstan-baseline.sh /path/to/extension
scripts/generate-report.sh /path/to/extension
```
