• This toggle is global, not code-review-specific: both agent runners call resolve_config_plugins(...) unconditionally for every category, and the evaluation workflows default to bug-fix. As a result, bug-fix and test-generation runs will also clone/load BCQuality and be recorded as plugin experiments, contrary to this PR's code-review-only experiment scope. Gate this plugin by EvaluationCategory.CODE_REVIEW or supply a category-specific experiment configuration.

• Invoking this skill introduces an incompatible output contract. The pinned BCQuality skill mandates a findings-report object whose entries use message plus nested location.file/location.line, while parse_review_output() only recognizes top-level file/line_start and body fields. If the skill follows its own contract, every finding is silently skipped and the evaluation records an empty review. Add an explicit BCQuality-to-benchmark adapter (or parser support) rather than relying on the model to violate the skill contract and rewrite the shape.
