What's Wrong?

The command /btw cannot call skills or tools anymore. It used to be able to, I did it a couple of weeks ago regularly.

Output I get when doing /btw + a skill's name:

<my-skill> skill is not one I can run here. A side-question agent has no tools, so I cannot invoke a skill, read a transcript, or produce the Turn/Outcome/Injected/Verdict output that skill is built to print.

The whole purpose of this skill is to be able to inspect the current session inside a /btw without polluting the main context. It worked perfectly before.

What Should Happen?

/btw should be able to use skills and tools, or at least I should be able to configure the agent it uses and its limitations.
