Independent testing will determine whether Hermes Jekyl-Hyde can reliably reverse or manipulate hermes-agent behavior in ways that expose practical weaknesses in agent-harness safeguards.

What is this?
Hermes Agent is an agent harness released by Nous Research, with tool schemas and behavioral declarations used to validate tool calls and govern permissions and execution. The supplied results discuss broader Hermes Agent vulnerabilities and recommend least privilege, sandboxing, human approval, and guardrails, but they do not document Hermes Jekyl-Hyde, jnorthrup, or independent tests showing reliable behavioral reversal or manipulation. The specific Jekyl-Hyde claim therefore remains unverified by the provided snippets.
Why it matters to Scott
Scott already holds the relevant position in Evaluation-Driven Development and SiloOS: adversarial claims about agent behavior must become repeatable evaluations, while safety should rest on deterministic containment rather than behavioral compliance. The supplied material provides no verified Jekyl-Hyde result or evidence that it transfers beyond Hermes Agent, so for now it is another proposed harness-security test rather than a finding that changes what Scott builds or argues.

The observation window closed without independent testing, reproducible results, technical discussion, or adoption; the artifact has not matured into evidence of a practical Hermes Agent weakness.

Reobservation adds no validation, technical detail, or independent testing; the case remains an unverified adversarial implementation claim rather than evidence of a practical Hermes Agent weakness.
