reviewing-content-security-policy skillA

reviewing-content-security-policy is agent-read markdown (skill) from unboundcompute/security-agent-skills: Review a content security policy as a script-injection defense and judge whether it would actually stop injected script, with the discipline that a weak policy is a real finding mainly where an injection sink it would otherwise block exists. Covers a script source that allows inline script with no neutralizing nonce or hash, that allows arbitrary hosts or data URLs, or that trusts a host serving attacker-usable script; a nonce that is static, reused, low-entropy, or reflected from input; a missi.

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 unboundcompute/security-agent-skills/reviewing-content-security-policy@git:20260821.57dfaf1
Exact content
mdr add unboundcompute/security-agent-skills/reviewing-content-security-policy@sha256:26db5aa80fff6f1d

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.
