Intelligently updates CHANGELOG.md and documentation by tracking work sessions.Accumulates multiple related changes into ONE coherent entry instead of fragmented updates.Use this when:- User says "start working on X" or "fixing Y" (session start)- User says "done", "ship it", "finished with X" (session end - trigger docs update)- User asks to update changelog after multiple commitsDO NOT update docs after every small change. Wait for session completion.
