Hey @Moumouls!

I think you’re mixing two concept.

  • Commands will always be run by the model selected for a chat. They exist under ./cursor/commands
  • Subagents can be configured to use specific models (like you have). Subagents are not invoked by slash commands. The agent intelligently decides when to you use them, or you can nudge them to (“Use the create-pr subagent”)

So why i can “/a-sub-agent” it’s so confusing @Colin ?

Ah sorry @Moumouls, looks like I’m wrong!

I can reproduce the model behavior, but typically only on the first subagent invocation after specifying the model. We have an open bug for this, and I’ll add your report.

So @Colin , using /sub-agent is expected to invoke the agent mentioned in the file ?

I think it’s smart because it allows some kind of “custom agents” for specific tasks, explicitly invoked by the developer.

Can confirm that this issue:

Will be fixed in 2.5 (around the corner)

Sorry for the delay on answering this one @Moumouls :folded_hands:

Yes! They function an awful lot like slash commands.

So @Colin , direct agent invocation will use provided model mentioned in the sub agent file ?
