Audit GitHub Actions for privilege and supply-chain risks with zizmor skillA

Audit GitHub Actions for privilege and supply-chain risks with zizmor is agent-read markdown (skill) from agentskillexchange/skills: Run a focused security pass on GitHub Actions workflows before merge so token misuse, dangerous permissions, and unpinned actions are caught early..

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.
