shell-execution-sandbox skillA

shell-execution-sandbox is agent-read markdown (skill) from tylerjrbuell/reactive-agents-ts: Enable and configure the sandboxed shell execution tool with command allowlists, Docker isolation, and audit logging for agents that run terminal commands..

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 tylerjrbuell/reactive-agents-ts/shell-execution-sandbox@v2.0
Exact content
mdr add tylerjrbuell/reactive-agents-ts/shell-execution-sandbox@sha256:5a284bc7aaf36ede

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.
