Add notes to the knowledge repository. Use whenever the user provides content to save (commands, config, code, CLI output, explanations) or says "add/save/note/record this", "find a place for this", "记录一下", "添加笔记". Do NOT use for creating new topics from scratch or splitting/reorganizing notes (use splitting-notes skill).
Use when note files exceed 1000 lines or need better organization. Splits large note files into smaller, focused files with index files for navigation, following progressive grouping principles with clear hierarchy.
