Keeps IdeaVim documentation in sync with code changes. Use this skill when you need to verify documentation accuracy after code changes, or when checking if documentation (in doc/, README.md, CONTRIBUTING.md) matches the current codebase. The skill can work bidirectionally - from docs to code verification, or from code changes to documentation updates.

Maintains IdeaVim changelog (CHANGES.md) and build.gradle.kts changeNotes. Use when updating changelog, documenting releases, or reviewing commits/PRs for changelog entries.
