Teach ReacherX how you want to work
Save useful instructions, correct the audience, and understand what △ Agent can learn from later work.
You shouldn't have to make the same correction every time you use ReacherX. If you always want the first message to be short, tell it to remember that. If your workshop is free, make sure it knows that too.
You can do this by talking to △ Agent. There isn't any code to write.
Tell it what to remember
Try a request like this in the workspace where you want it used:
Remember this for outreach: keep the first message under 80 words. Ask one question. Don't ask for a meeting in the first message.
Wait for confirmation that it saved the instruction. If it only says it understands, ask it to save it as workspace memory. That makes it available for later work in this workspace.
You can give it a demo or an approved explanation too. Say what the file is for and when to use it. The attachment alone won't explain what you have in mind.
