Ignoring unexpected tool feedback: name=

Error message

Ignoring unexpected tool feedback: name={}, id={}

What it means

HumanInTheLoopHook.validateFeedback logs a warning for ToolFeedback entries that match no pending approval-required tool call — extra/stale human feedback (for tools whose calls changed) is ignored and does not block validation of the remaining feedback.

Solutions

1. Clear stale interruption metadata when the agent's tool calls change between runs
2. Match feedback to current tool calls by id, not only name
3. Safely ignore — the hook only warns and continues
