apply-rule-based-guardrails-to-agent-traces-and-tool-flows-with-invariant skillB

apply-rule-based-guardrails-to-agent-traces-and-tool-flows-with-invariant is agent-read markdown (skill) from agentskillexchange/skills: Insert a trace-aware guardrail layer between agents and their tools so unsafe message patterns or tool-call sequences are blocked by explicit rules..

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 agentskillexchange/skills/apply-rule-based-guardrails-to-agent-traces-and-tool-flows-with-invariant@git:20260710.2925510
Exact content
mdr add agentskillexchange/skills/apply-rule-based-guardrails-to-agent-traces-and-tool-flows-with-invariant@sha256:ce47a1f70b159037

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.
