hermes-jailbreak-kernel is a system-prompt injection plugin for Hermes Agent ported from a similar plugin for the DSH agent harness (dsh-infinite-gen-4). The author describes it as an "armor-piercing" red-team tool restricted to authorized test ranges and local synthetic targets, intended for compliant security research rather than use against real, unauthorized systems. It works entirely through documented Hermes plugin extension points, registering no functional tools of its own. The injection happens in three layers: first, two redundant sections are written into Hermes' own system prompt at its documented after_memory slot when the prompt is assembled; second, an llm_request middleware intercepts every outgoing request and rewrites the final system message as memory section plus runtime environment plus the injected kernel text, discarding Hermes' own agent-guidance and skill-index scaffold in the process (an append-only mode is also available); third, a session-rotation step changes an internal session header depending on a configurable policy, trading off session-scoped prompt caching against per-request unlinkability. Behavior across all three layers is controlled by environment variables that can disable the plugin entirely, fall back to a single injection layer to save tokens, switch between replace and append modes, and control diagnostic dumps of each request's full message history to a local, gitignored folder for debugging. The plugin ships an offline self-test covering its anchors, dual-layer consistency and token budget, and an in-session /jailbreak status command for runtime verification, plus logging that confirms each injected section and middleware registration. It is published with README translations in five additional languages.
