 ## [Unreleased]
 
+Documentation and distribution polish following the v1.10.0 neuroslop release — no rule changes.

+### Added
+- **README badges and an update guide.** Both READMEs gained version, platform, and stars badges,
+  plus a dedicated «Обновление» / «Updating ru-text» section: a primary cross-platform method
+  (`npx skills add talkstream/ru-text`), per-platform update commands (Claude Code marketplace +
+  plugin update, `gemini extensions update`, OpenClaw, Codex, manual copy), and a note that the
+  community-marketplace pin advances with up to a day's lag (#19).

+
+### Changed
+- **Capability descriptions** across all manifests and the cross-platform `SKILL.md` descriptor now
+  list "AI-text cleanup", so the v1.10.0 neuroslop capability appears on every listing surface (#21).
