Agent work, not chat

HERMES-NATIVE TOOL CALLINGStructured tool calls in the format agents already speak — no wrapper prompts, no parsing glue.

MULTI-STEP WORKFLOWSGRPO over full agent episodes: plans, function chains, and long-horizon task completion.

FAILURE RECOVERYTrained on recovery from failed calls and bad tool output — the part of agent life chat models never see.
