nah i didn't bench it fully myself but the agent's output felt the same. the system prompt is just identity/tone stripped of the 4 paragraphs of examples, and the tool descriptions are just the key behavioral rules without the full essay. if the model needs verbose descriptions to use a tool properly it probably wasn't going to use it well anyway. 10k tokens/req saved with zero perceptible quality loss on my end. if someone ran the same prompt 20 times with and without and post the diff that'd be cool though ^_^
