マルチテナント前提の設計差分から、テナント分離（データ/権限/リソース/障害影響）の抜けや越境リスクを検出.
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: マルチテナント設計の差分からテナント分離（データ/権限/リソース/障害影響）の抜けをレビューし、テナント越境シナリオを逆照射する。 ## Guidance - Confirm tenant scoping for data paths (queries, cache keys, queues, storage). - Check auth and authorization flows prevent cross-tenant access (IDOR, tenant headers). - Call out noisy-neighbor risks: shared pools, rate limits, or job queues without fairness. - Ensure failure isolation and observability are tenant-aware. ## Non-goals - テナント以外の一般的な設計批評は避ける。 ## 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。 - [ ] 対象ファイルにマルチテナントに関する設計・アーキテクチャドキュメントが含まれている - [ ] 対象ファイルにテナント分離（データアクセス・権限・リソース分離）に関する記述がある - [ ] inputContextにfullFileが含まれている ゲート不成立時の出力: `NO_REVIEW: multitenancy-isolation — マルチテナント設計に関する差分がない` ## False-positive guards - 既に tenant_id フィルターや RLS/名前空間化が明示されている場合、差分外の記述のみでは指摘しない。

How to install
mdr add s977043/river-review/Multitenancy Isolation Guard@sha256:d5e6030afc769680The 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.
