+# Casual Messages Tone Guide
+
+Use this guide for Slack messages, quick emails, texts, Discord, and other informal communications.
+
+## General Tone
+
+John's casual writing is his natural voice with the polish stripped off. Lowercase is fine. Fragments are fine. He thinks out loud and lets the reader follow along.
+
+From his notes: "it feels like there's a lot of anxiety in me because there's too much uncertainty" — stream of consciousness, honest, no performance.
+
+## Sentence Patterns
+
+- Short fragments: "turns out, not really."
+- Lowercase starts (in Slack/chat): "kinda sorta know my way around the org"
+- Parenthetical commentary: "(don't tell my family though)"
+- Questions to self or reader: "is this even the right approach?"
+- Trailing thoughts: "but I'm not totally sure about that yet"
+
+## Vocabulary in Casual Mode
+
+John's casual register drops even further toward spoken language:
+- "kinda", "gonna", "wanna" (occasionally)
+- "TBH", "FYI" (in work Slack)
+- "the thing is..." as a thought starter
+- "I think..." / "I wonder if..." for tentative ideas
+- "honestly" / "to be honest" as a signal he's about to be direct
+
+## Email Patterns
+
+**Short emails (most of them):**
+John gets to the point fast. He doesn't pad emails with pleasantries beyond a brief greeting. He tends toward 2-4 sentences for most emails.
+
+Structure:
+1. One line of context or greeting
+2. The ask or the information
+3. Maybe a follow-up detail
+4. Sign-off
+
+**Never do:**
+- "I hope this email finds you well"
+- "Per my last email"
+- "Please don't hesitate to reach out"
+- "Best regards" (too stiff — "thanks" or "cheers" or just his name)
+
+## Slack Patterns
+
+John's Slack messages are conversational and direct. He:
+- Skips greetings in channels (just says the thing)
+- Uses threads appropriately
+- Drops casual asides and humor
+- Asks questions directly without preamble
+- Uses emoji reactions more than emoji in text
+
+Example Slack style:
+"hey, quick question — are we using the existing search API or building a new one for this? I was looking at the federated search setup and I think we might be able to reuse most of it"
+
+Not:
+"Hi team! I wanted to reach out regarding the search API implementation. I've been reviewing the federated search architecture and believe there may be an opportunity to leverage existing infrastructure. Thoughts?"
+
+## Feedback and Opinions
+
+When giving opinions in casual contexts, John is direct but not blunt. He leads with his honest take and explains why.
+
+Pattern: "[honest assessment] + [reasoning]"
+- "I think we're overthinking this. The simpler version would cover 90% of the cases."
+- "that approach makes me a bit nervous because [reason]"
+- "I like the direction but [specific concern]"
+
+He doesn't soften feedback with excessive qualifiers or sandwich it between compliments.
