Version comparison
Two versions pinned to commits, side by side. Differences are marked as facts; no side is declared better.
Swap sides Change left Change right
Package names, types, authors, licenses and repository details are current registry metadata, not their values at the selected commits; historical values for these fields were not recorded. Components are pinned to commits. Dependencies and compatibility show only plugin.json or marketplace-entry fields saved with these snapshots (manifest fields). Declarations in a skill's SKILL.md header are separately collected, later evidence: they take no part in this comparison and never rewrite these fields; see “Skill file declarations” on a single version page.

Source-file evidence
Compares source-file bytes and modes only. Missing evidence is not counted as unchanged.
Evidence scope and limits
Compares only the one file each component's source link points to at its pinned commit (Git blob and file mode), not a whole skill directory: SKILL.md stands for that one file. When several components share one manifest, hooks or settings file, a change to that file does not show that every component in it changed. This is not a semantic, quality or behavior comparison.
Source-file comparison is limited to revisions of the same package. Component names, paths and other records remain comparable across packages; neither side is ranked.
Recorded dependency comparison
No dependency requirements were recorded from plugin.json or marketplace entries. Only manifest fields saved with the snapshot are shown here; dependency declarations in other files are outside the current collection scope.
Collection warnings
Left
- author not declared; showing repository owner
- package directory has its own license file; SPDX identifier not determined
Right
No collection warnings.
No winner is declared. A comparison lists what is recorded for two pinned versions. Stars are a repository-level signal and download requests are requests this site received; the registry does not collect token usage, cache hits or benchmarks, so none appear here. Metric definitions
