Camoa Claude Skills Code Pattern Checker

Code Pattern Checker

Validate code against Drupal standards and best practices.

Required References

Load these before checking code:

For security and frontend checks, WebFetch from https://camoa.github.io/dev-guides/ instead of reading bundled files.

Activation

Activate when you detect:

• Before committing code
• After implementation, before task completion
• /drupal-dev-framework:validate command
• "Check my code" or "Review this"
• Invoked by task-completer skill

Gate Enforcement

This skill enforces Gate 1: Code Standards from references/quality-gates.md. Code CANNOT be committed until Gate 1 passes.

Workflow

1. Identify Files to Check

Ask if not clear:

Which files should I check?
1. All changed files (git diff)
2. Specific file(s)
3. All files in a component

Your choice:

Use Bash with git diff --name-only to get changed files if option 1.

2. Read and Analyze Files

Use Read on each file. For each, check:

PHP Files:

• PSR-12 / Drupal coding standards
• Docblocks on classes and public methods
• Type hints on parameters and returns
• No deprecated functions
• Naming: PascalCase classes, camelCase methods

SOLID Principles (references/solid-drupal.md):

• Single Responsibility - one purpose per class
• Dependency Inversion - inject dependencies via services.yml
• No \Drupal::service() in new code (BLOCKING)
• Interfaces defined for services

DRY Check (references/dry-patterns.md):

• No duplicate code blocks (BLOCKING)
• Shared logic in services/traits
• Leverages Drupal base classes

Security (dev-guides drupal/security/):

• No raw SQL with user input (BLOCKING)
• Output escaped (Twig auto, Html::escape)
• Form tokens present (Form API handles)
• Access checks on routes (BLOCKING)
• Input validated via Form API

CSS/SCSS (dev-guides drupal/sdc/ + drupal/js-development/):

• Mobile-first media queries
• No !important (BLOCKING)
• No @extend (BLOCKING)
• BEM naming convention
• Drupal behaviors pattern for JS

3. Run Automated Tools

Suggest running (user executes):

# PHP CodeSniffer
ddev exec vendor/bin/phpcs --standard=Drupal,DrupalPractice {path}

# PHPStan (if configured)
ddev exec vendor/bin/phpstan analyze {path}

# SCSS Lint (if applicable)
npm run lint:scss

4. Report Findings

Format output as:

## Code Check: {file or component}

### Status: PASS / ISSUES FOUND

### Standards Check
| Check | Status | Notes |
|-------|--------|-------|
| PSR-12 | PASS | - |
| Docblocks | ISSUE | Missing on processData() |
| Type hints | PASS | - |

### SOLID Principles
| Principle | Status |
|-----------|--------|
| Single Responsibility | PASS |
| Dependency Inversion | PASS |

### Security
| Check | Status | Notes |
|-------|--------|-------|
| SQL Injection | PASS | Uses query builder |
| XSS | PASS | Output escaped |
| Access Control | ISSUE | Missing on /admin/custom route |

### DRY Check
| Issue | Location |
|-------|----------|
| Duplicate logic | lines 45-52 and 78-85 |

### Issues to Fix (Priority Order)
1. **Security**: Add access check to admin route
2. **Standards**: Add docblock to processData()
3. **DRY**: Extract duplicate logic to private method

### Recommendation
- [ ] Fix security issue before merge
- [ ] Other issues: fix now or create follow-up task

Approved for commit: NO (fix security first) / YES

5. Offer Fixes

For each issue, offer to help:

Issue: Missing docblock on processData()

Suggested fix:
/**
 * Process the input data and return results.
 *
 * @param array $data
 *   The input data array.
 *
 * @return array
 *   The processed results.
 */

Apply this fix? (yes/no/skip)

Stop Points

STOP and wait for user:

• After asking which files to check
• After presenting findings
• Before applying each fix
• If security issues found (emphasize fixing)
