fix(ce-release-notes): backtick-wrap <skill-name> token in description (#603)

plugins/compound-engineering/AGENTS.md

@@ -83,6 +83,7 @@ When adding or modifying skills, verify compliance with the skill spec:
 - [ ] `name:` present and matches directory name (lowercase-with-hyphens)
 - [ ] `description:` present and describes **what it does and when to use it** (per official spec: "Explains code with diagrams. Use when exploring how code works.")
 - [ ] `description:` value is quoted (single or double) if it contains colons -- unquoted colons break `js-yaml` strict parsing and crash `install --to opencode/codex`. Run `bun test tests/frontmatter.test.ts` to verify.
+- [ ] `description:` value does not contain raw angle-bracket tokens like `<skill-name>`, `<tag>`, or `<placeholder>` -- Cowork's plugin validator parses descriptions as HTML and rejects unknown tags with a generic "Plugin validation failed" banner (see issue #602). Claude Code tolerates them, so the bug only surfaces downstream. Backtick-wrap the token (`` `<skill-name>` ``) or rephrase. Enforced by `tests/frontmatter.test.ts`.
