  # Ignore paths from review

    - "!**/__snapshots__/**"

  # Stack-specific review instructions
  path_instructions:
    - path: "apps/api/**"
      instructions: |
        - Check for missing input validation (Zod schemas required on all handlers)
        - Flag any database queries without proper RLS consideration
        - Ensure all async functions have try/catch or error boundaries
        - Check for N+1 query patterns (missing .include() or DataLoader usage)
    - path: "apps/web/**"
      instructions: |
        - Check for missing `key` props in .map() renders
        - Flag `useEffect` without proper cleanup functions
        - Check for missing `alt` attributes on images
        - Verify Server Actions are properly validated with Zod
    - path: "apps/admin/**"
      instructions: |
        - All admin routes must verify isSuperAdmin === true
        - Flag any direct DB access without service role client
        - Check for proper audit logging on destructive operations

  # Custom review rules for the entire codebase
  instructions: |
    Review with these priorities:
    1. SECURITY: SQL injection, XSS, auth bypass, exposed secrets
    2. CORRECTNESS: Logic bugs, off-by-one errors, type unsafety
    3. PERFORMANCE: N+1 queries, unnecessary re-renders, bundle size
    4. MAINTAINABILITY: Code duplication, naming, SOLID violations
    5. STYLE: Only comment if it's a significant clarity issue
    6. SOVEREIGN ANTI-SLOP: Flag placeholders (// TODO, // ...), mock data in prod, syntax comments, and silent error suppression

Agentic Review Mode (CodeRabbit 2.x)

CodeRabbit 2.x introduces agentic review — deep analysis that can read multiple files, run tools, and understand architectural context:

# Trigger agentic review in PR comment:
@coderabbitai review

# Ask specific questions:
@coderabbitai What is the security impact of changes in apps/api/src/routes/users.ts?
@coderabbitai Can you generate a test for the createWorkspace function?
@coderabbitai Is there a N+1 query issue in this PR?
@coderabbitai Summarize the architecture changes in this PR

CI/CD Integration (GitHub Actions)

CodeRabbit vs Manual Review — Best Practices

• CodeRabbit first: Let it run before human reviewers — catches the obvious issues.
• Human focus: After CodeRabbit, humans focus on business logic, architecture intent, and product decisions.
• Teach it: Dismiss false positives with an explanation — CodeRabbit learns your patterns.
• Custom instructions: Invest time in path_instructions for your specific stack — dramatically improves relevance.

Integrasi Orkestrasi

Terhubung dan mengorkestrasi skill domain yang relevan seperti brainstorming, zero-to-prod-orchestrator, dan session-memory-manager untuk memastikan eksekusi yang kohesif.

Deskripsi

Panduan ahli untuk mengonfigurasi dan memanfaatkan CodeRabbit 2.x — review kode otomatis bertenaga AI, ringkasan pull request, dan umpan balik developer interaktif. Mencakup konfigurasi, aturan review kustom, integrasi dengan CI/CD, dan mode review agentik.

Kondisi Pemicu

• Menyiapkan CodeRabbit di repositori GitHub atau GitLab.
• Mengonfigurasi aturan review kustom untuk tech stack Anda.
• Menggunakan mode agentik CodeRabbit untuk review arsitektur mendalam.
• Mengintegrasikan umpan balik CodeRabbit ke dalam quality gate CI/CD.
• Menulis instruksi kustom yang kompatibel dengan CodeRabbit di .coderabbit.yaml.

Fitur Utama CodeRabbit 2.x

Konfigurasi (.coderabbit.yaml)

Tempatkan .coderabbit.yaml di root repositori. Konfigurasi kunci:

• reviews.profile: assertive (ketat), chill (santai), default.
• reviews.path_instructions: Instruksi review kustom per direktori — sangat berguna untuk menerapkan standar spesifik stack.
• reviews.path_filters: Kecualikan file lock, migrasi, kode yang dihasilkan dari review.
• reviews.instructions: Aturan global untuk seluruh codebase dengan prioritas eksplisit.

Mode Review Agentik (CodeRabbit 2.x)

Mode agentik memungkinkan CodeRabbit membaca banyak file, menjalankan tool, dan memahami konteks arsitektur. Picu dengan @coderabbitai review di komentar PR atau ajukan pertanyaan spesifik tentang dampak keamanan, masalah N+1, atau perubahan arsitektur.

Integrasi CI/CD (GitHub Actions)

Gunakan action coderabbit-ai/wait-for-review@v1 untuk menunggu review selesai dan memblokir merge jika masalah kritis ditemukan.

CodeRabbit vs Review Manual — Best Practices

• CodeRabbit dulu: Biarkan berjalan sebelum reviewer manusia — menangkap masalah yang jelas.
• Fokus manusia: Setelah CodeRabbit, manusia fokus pada logika bisnis, niat arsitektur, dan keputusan produk.
• Ajarkan: Tolak false positive dengan penjelasan — CodeRabbit belajar pola Anda.
• Instruksi kustom: Investasikan waktu di path_instructions untuk stack spesifik Anda — meningkatkan relevansi secara dramatis.
