+
+& "%PLUGIN_DIR%\mcode-island\notify-island.ps1" -State done -Message "Bash ok"
+# → pill renders: "Bash ok"  (no step → legacy behavior, backward compat)
+```
+
+All three params are optional and backward compatible. The detail field
+replaces the message in the rendered pill when present (avoids stacking
+"Bash ok · fill username"). See `skills/mcode-island/SKILL.md` for the
+full semantics and the contract with the widget renderer.
