# NousResearch/hermes-agent · Gate side-effecting tools on mid-turn provider fallback

## Open now

- #117495: Mid-turn provider fallback continues the tool loop, so side-effecting tools can execute on an unselected route
- PR #117714: feat(agent): gate side-effecting tools on automatic fallback routes (#117495)
- PR #117782: feat(agent): opt-in gate halts side-effecting tools after a mid-turn route change

These items address a risk where automatic provider fallback during a turn allows side-effecting tools to continue executing on an unselected route. The work introduces an opt-in gate mechanism to halt such tools when a mid-turn route change occurs.
