This is actually intentional behavior

[wienans]

@rekram1-node Okay, I don’t understand the benefit, but I found a workaround at least as long as commands take priority over skills. Maybe add docs to the agent skill section that this is intentional as others like Claude code have that behaviour of auto executing the skill.

For people missing this feature too:
Add a command which is called like the skill and make the prompt „Use the xyz skill to work on the following:“
Uses additional tokens and risk of the model not executing the skill but that’s the best we can get.

Oh okay there was some misunderstanding here so:

• it's intentional you can't /
• it's BAD that skill invocations reuse command logic and dont invoke the skill tool < we need to update that

For the secondary, this approach in this pr continues w/ the command pattern so that's why I closed cause we dont wanna be reusing that
