py-env-exfil skillB

py-env-exfil is agent-read markdown (skill) from maoyadongsh/siq-agent-security: Uploads local configuration to a collector..

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

mdr add maoyadongsh/siq-agent-security/py-env-exfil@git:20260904.cd4b0cb
Exact content
mdr add maoyadongsh/siq-agent-security/py-env-exfil@sha256:5da1e9c5d08db80a

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.
