An AEC agent kit keeps one shared house-rules block synced across all 24 skills by script. A rule meant for Revit skills, call get_context first and stop on revit_busy, now reaches the feedback skill and four Rhino skills. In a session with no Revit open, the agent had to decide to ignore a house rule. The author notes a stricter agent would call a pyRevit tool for no reason or report a false "Revit is not running." Proposed fix is to scope the rule per tool. Small, but it's exactly what multi-tool agent setups run into once rules are shared.
