Laravel Eloquent N+1 and Query Efficiency Review SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
Laravel Eloquent N+1 and Query Efficiency Review from s977043/river-review is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add s977043/river-review/Laravel Eloquent N+1 and Query Efficiency Review@v0.1.0Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

Detects N+1 query patterns (relation access inside loops without eager loading), full-table get()/all() loads, and unsafe chunk()/cursor() usage in Laravel Eloquent code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Pattern declaration
Primary pattern: Reviewer
Secondary patterns: Inversion
Why: Eloquent のクエリ効率規約への適合をチェックリスト型で検査する
## Goal / 目的
- ループ内 relation アクセスによる N+1 クエリ（公式例: 25 件で 26 クエリ）を検出する。
- 巨大テーブルの全件ロード（`all()` / `get()`）と、`chunk()` / `cursor()` の誤用を検出する。
## Non-goals / 扱わないこと
- mass assignment / 認可（`laravel-mass-assignment` のスコープ）。
- migration の安全性（`laravel-migration-safety` のスコープ）。
- SQL チューニング一般・index 設計。
## Pre-execution Gate / 実行前ゲート
このスキルは以下の条件が**すべて**満たされない限り`NO_REVIEW`を返す。
- [ ] 差分に Eloquent モデルのクエリ・relation アクセスの追加変更が含まれている
- [ ] diff コンテキストが利用可能である
ゲート不成立時の出力: `NO_REVIEW: laravel-eloquent-nplus1 — Eloquent クエリの変更なし`
## False-positive guards / 抑制条件
- ループ前に `with()` / `load()` 済みの relation へのアクセスは指摘しない（diff 外で eager load されている可能性があるため、確証がなければ質問に留める）。
- ループ対象が少数固定（config 由来等）の場合の relation アクセスは指摘しない。
- `chaperone()` を使った親逆参照は正当。
- `preventLazyLoading` が有効なプロジェクトでは N+1 がテストで落ちるため、重複指摘を避ける。
## Rule / ルール
- ループ内で relation を参照する場合は `with('relation')`（取得後なら `load()` / `loadCount()`）で eager load する。
- 巨大テーブルの反復は `chunkById` / `lazyById` / `cursor` を使う。
- `chunk()` でフィルタ対象カラムを更新しない（公式: inconsistent results。`chunkById` を使う）。

How to install
mdr add s977043/river-review/Laravel Eloquent N+1 and Query Efficiency Review@sha256:715033b73c9caf24The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
