Invisible Unicode Injection Scan 不可視 Unicode コード注入検出 skillA

Invisible Unicode Injection Scan 不可視 Unicode コード注入検出 is agent-read markdown (skill) from s977043/river-review: 差分に追加されたソースコードへ混入した不可視・危険な Unicode 文字（タグ文字・異体字セレクター・ゼロ幅文字・双方向制御/マーク・変則空白）を検出する。GlassWorm 型サプライチェーン攻撃・ASCII smuggling・Trojan Source（CVE-2021-42574）でコードを不可視化する手口を、決定論的な静的解析（列挙した code point 集合に限定）として捕捉し、canary テストで誤検出の再発を防ぐ.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add s977043/river-review/Invisible Unicode Injection Scan 不可視 Unicode コード注入検出@v0.1.0
Exact content
mdr add s977043/river-review/Invisible Unicode Injection Scan 不可視 Unicode コード注入検出@sha256:2b56b45296907578

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
