Claude AI as Your Laravel Code Reviewer: Smarter PRs, Safer Deployments

Code review is the last line of defence before production. But human reviewers get tired, miss patterns, and bring their own biases.

Enter Claude AI — a context-aware assistant that can review Laravel pull requests for:

• 🔐 Security vulnerabilities
• 🎯 Style and architectural consistency
• ⚙️ Performance issues (N+1 queries, eager loading)
• 🧠 Anti-patterns and maintainability risks

This blog shows how Claude can become your Laravel team’s AI-powered reviewer, catching mechanical issues so humans can focus on design and business logic.

🤖 Why Use Claude for Laravel Code Reviews?

Claude doesn’t replace human judgment — it augments it.

Claude excels at:

• Parsing large diffs and spotting repetitive mistakes
• Enforcing PSR-12 and Laravel conventions
• Suggesting safer alternatives for risky code
• Flagging missing authorization, validation, or error handling

Claude struggles with:

• Business logic decisions
• Context across multiple PRs or tickets
• Subjective design debates

So the ideal workflow is:

Claude handles the mechanical. Humans handle the meaningful.

🛠️ Setup: Claude in Your Laravel PR Workflow

You can integrate Claude via:

• GitHub Actions (e.g. claude-code-security-review)
• Claude API + custom CI/CD scripts
• Claude in Slack or Claude in Chrome for ad-hoc reviews

Recommended setup:

• Trigger Claude on every PR
• Feed it the diff + relevant context (models, policies, routes)
• Ask for structured feedback: security, style, performance, readability

🧪 Example: Before vs After Claude Review

PR Diff (Before)

public function store(Request $request)
{
    $invoice = new Invoice;
    $invoice->amount = $request->amount;
    $invoice->status = 'pending';
    $invoice->user_id = auth()->id();
    $invoice->save();

    return redirect('/invoices');
}

Claude Feedback

• ❌ No validation — user could submit invalid data
• ❌ No authorization check — any user can create invoices
• ❌ Hardcoded status — should use enum or config
• ✅ Suggests using Invoice::create() for brevity

PR Diff (After)

public function store(Request $request)
{
    $this->authorize('create', Invoice::class);

    $validated = $request->validate([
        'amount' => 'required|numeric|min:0',
    ]);

    Invoice::create([
        'amount' => $validated['amount'],
        'status' => InvoiceStatus::PENDING,
        'user_id' => auth()->id(),
    ]);

    return redirect()->route('invoices.index');
}

Claude’s suggestions improved:

• ✅ Security (authorization)
• ✅ Data integrity (validation)
• ✅ Maintainability (enum usage)
• ✅ Readability (shorter code)

🔐 Security Checks Claude Can Catch

Claude is especially good at spotting Laravel-specific security gaps:

• Missing authorize() calls
• Unvalidated $request usage
• Direct access to sensitive models without policies
• Unsafe query building (e.g. raw SQL injection risks)
• CSRF or session misuse in custom middleware

You can prompt Claude with:

“Review this Laravel controller for security risks and suggest improvements.”

---

🎯 Style Enforcement With Claude

Claude can enforce:

• PSR-12 formatting
• Consistent naming (storeInvoice() vs create())
• Blade best practices (@foreach vs @each)
• Route naming conventions (invoices.index vs /invoices)
• Service layer separation (controller vs business logic)

Example Prompt:

“Review this Laravel controller for style and architectural consistency. Suggest improvements.”

---

⚙️ Performance Checks

Claude can flag:

• N+1 query risks
• Missing eager loading (with())
• Inefficient pagination
• Unindexed filters
• Overuse of get() vs cursor()

Example Prompt:

“Review this Laravel model and controller for performance issues. Focus on query optimization.”
