• Use with other agents. The style body is provider-agnostic; only Claude Code's YAML
  frontmatter is Claude-specific. New README section with one-line installs for Devin, Codex,
  and Antigravity CLI (agy), stripping the frontmatter at a <!-- body-start --> marker. No
  duplication, no drift. (PR #1, danikdanik)
• Version marker in every style file. Each style now carries a <!-- attention-span vX.Y -->
  line so you can tell whether your downloaded copy is current: grep attention-span ~/.claude/output-styles/*.md, then compare to the version badge.
• README badges (version, license, styles, token savings) and a release.yml workflow that
  fails the release if VERSION, the in-file markers, and the tag ever drift.
• Spanish README (README.es-ES.md), with a language switcher on both. (PR #2, webbrain-one)

Attention-kind + Spartan: answer vs deliverable split; tighten the expansion bar; no word cap by design. First tracked version.
