 All frontmatter is optional at runtime. Add a clear `description` when the model should discover the skill; skills without one are not advertised.
 
-`opencode/autoinvoke: false` only hides the skill from the model's available list. The skill remains registered and can still be loaded explicitly by ID. V2 accepts portability fields such as `license` and `compatibility` but does not interpret them.
+`opencode/autoinvoke: false` only hides the skill from the model's available list. The skill remains registered and can still be loaded explicitly by ID. When both `disable-model-invocation` and `opencode/autoinvoke` are set, `opencode/autoinvoke` wins. V2 accepts portability fields such as `license` and `compatibility` but does not interpret them.
