Field notes
The described collection is read-only: it calls tools/list, prompts/list, and resources/list on public remote servers, and reads package or skill metadata without installing or executing it. For each changed definition, the page says it keeps both versions and applies plain-rule scores, including checks for hidden Unicode, new hosts, sensitive paths, and new maintainers. It says labels describe the diff rather than intent and link to raw diffs and proofs.
