identity-and-guardrails skillB
identity-and-guardrails is agent-read markdown (skill) from tylerjrbuell/reactive-agents-ts: Enable prompt injection detection, PII masking, behavioral contracts, kill switch controls, and audit logging for safe production deployments..
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 tylerjrbuell/reactive-agents-ts/identity-and-guardrails@v2.0mdr add tylerjrbuell/reactive-agents-ts/identity-and-guardrails@sha256:eb4dc57a0d1b0e48Pin 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.
