A minor clarification for the power tool because it was misinterpreted in a
proposal.
The purpose of the tool is not to fix the actual errors but to handle the
error metadata.
An example use-case can be to filter errors for navigation purposes and
apply new / remove existing metadata.
Best,
Dimitris
