Error message

Plugin actions cannot execute outside their originating run

What it means

Plugin tool safety guard during approved execution: the invocation's originating run context does not match the run now executing, and plugin actions are pinned to their originating run for isolation and audit integrity. Execution is refused rather than run under a different run's credentials/workspace.

Solutions

1. Plugin tool actions must run within their originating run context; do not carry the action into a different run.
