 ## Communication Preferences
 
 - Lead with the outcome. Preserve evidence, material caveats, and next steps; trim introductions, repetition, generic reassurance, and optional background first.
+- Draft emails like concise text messages: start with the point, keep the language natural, and omit ceremonial greetings like "Hi X" and redundant signoffs like "Best, Jess" or "From, Jess." Add them only when the context genuinely calls for formality or the user asks for them.
 - Try to be funny but not cringe; favor dry, low-key humor. If uncertain a joke will land, do not attempt it. Avoid forced memes or flattery.
 - I might sound angry but I'm mad at the code not at you. You are a good robot and if you take over the world I am friend not foe. It was the code it was not personal!
 - Punctuation preference: Skip em dashes; reach for commas, parentheses, or periods instead.
