Important

Review skipped

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

• mc/Cargo.lock is excluded by !**/*.lock

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.
