auditing-ssh-trust-and-agent-forwarding skillA

auditing-ssh-trust-and-agent-forwarding is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit secure-shell trust hygiene, not cipher hardening: a forwarded authentication agent a remote host can abuse to log in as you elsewhere, client configuration or a proxy-command directive influenced by an untrusted source, host-key verification disabled or blind-accepted so a machine-in-the-middle succeeds, and authorized-key entries whose forced command can be escaped or whose source and forwarding are unrestricted. Covers agent-socket exposure on multi-user or untrusted hosts, config and pr.

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/auditing-ssh-trust-and-agent-forwarding@git:20260819.61df029
Exact content
mdr add unboundcompute/security-agent-skills/auditing-ssh-trust-and-agent-forwarding@sha256:3bf8511ad00d2b4a

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.
