Committees: Committees cannot be the sole purpose of the proposal. It is an addition to the proposal and designed to carry out specific duties related to the proposal.
I also point to Mod precedent stating that to avoid committee-only violations, proposals needs to task member states with something that's unrelated to the committee:

Let's look at the two active clauses of Ban on Secret Treaties:
Challenged proposal wrote:
- All treaties and international agreements with the force of law, entered into by member nations shall be registered with the Compliance Commission, which shall publish those treaties and international agreements.
- Member nations may not invoke treaties or international agreements that have not been registered with the Compliance Commission.
As you can see, both active clauses relate to the committee in some way. If you take out everything that's unrelated to the Compliance Commission, you're left with nothing, which is a textbook violation of the committee-only rule.
