Often I am using Composer to debug an error message from the log or browser console. Typicallky, the error is self-explanatory and AI can figure out what it is about, and what is requested (fix it!) just from the pasted snipped without any additional asks.
Currently, composer does not allow empty submissions (even when there was copy&paste snippet) and I have to say something like “fix it” or even just “.”.
It’s not ideal for a user to need to send “.” stub message just to get things going. Let us send empty, when your (some simple local model) believes that pasted message represents an error, and is a sufficient as a call-for-action per se… Or just on any copy&pasted snippet
