GitHub Actions Workflow Security Review skillA

GitHub Actions Workflow Security Review is agent-read markdown (skill) from s977043/river-review: Reviews GitHub Actions workflow diffs for script injection of untrusted input, pull_request_target with untrusted checkout, over-broad GITHUB_TOKEN permissions, and unpinned third-party actions..

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/GitHub Actions Workflow Security Review@v0.1.0
Exact content
mdr add s977043/river-review/GitHub Actions Workflow Security Review@sha256:efc5bd53795c9339

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.
