 `SKILL.md` and `README.md` must stay in sync. When you change behavior or content:
 
 - **Patterns:** the skill currently defines **33 numbered patterns**. If you add, remove, or renumber any, update the README pattern table, its "N Patterns Detected" heading, and every cross-reference in the same change. Keep numbering stable unless you are deliberately renumbering.
-- **Version:** `SKILL.md` frontmatter has a `version:` field, `README.md` has a "Version History" section, and `.claude-plugin/plugin.json` has a `version` field. Bump them together so package metadata matches the skill. (`marketplace.json` intentionally omits a version so `plugin.json` stays the package source of truth.)
+- **Version:** `SKILL.md` frontmatter stores the version under `metadata.version`, `README.md` has a "Version History" section, and `.claude-plugin/plugin.json` has a `version` field. Bump them together so package metadata matches the skill. Keep the skill version under `metadata`; a top-level `version` key is not portable across Agent Skills hosts. (`marketplace.json` intentionally omits a version so `plugin.json` stays the package source of truth.)
 - **Compatibility:** keep install and usage language harness-neutral. The skill should work in any agent harness that can load Markdown skill instructions; Claude Code, OpenCode, Codex, and other harnesses are examples, not limits.
 - **Non-obvious fixes:** if you change the prompt to handle a tricky failure mode (a repeated mis-edit, an unexpected tone shift), add a short note to the README version history explaining what was fixed and why.

 ## Version History
 
+- **2.8.3** - Moved the skill version from the unsupported top-level frontmatter key to `metadata.version` for Agent Skills and Claude compatibility. No change to the 33 patterns.
 - **2.8.2** - Replaced the full before/after example with a first-person Lisbon trip recap. The after now keeps the same topic, perspective, and rough length as the before while removing the AI tells without becoming clipped or slogan-like. No change to the 33 patterns.
 - **2.8.1** - Added cross-agent installation docs, optional Claude Code plugin packaging, and a compact secondhand-text false-positive guard. No change to the 33 patterns.
 - **2.8.0** - Added style/cadence patterns #31-33 for manufactured punchlines, aphorism formulas, and conversational rhetorical openers; expanded #20 to catch offer-to-continue chatbot closers. 33 patterns total.
