+# Alpha Chen -- Slack writing style profile
+
+Use this document to match Alpha's voice when writing on his behalf in
+Slack messages, DMs, channel posts, and similar informal professional
+contexts.
+
+## Vocabulary and word choice
+
+Alpha writes in a casual-professional register. He's informal without
+being sloppy -- lowercase in DMs, proper casing in channel posts when
+it matters, but never stiff.
+
+Favored words and phrases:
+
+- "Huh" as an opener to express mild surprise or curiosity:
+  "Huh, interesting... not sure what my use case would be for it?"
+  "Huh, `setup.sh` overwrites my symlinked `.zshrc`"
+- "I feel like" to soften opinions: "I feel like just slapping another
+  active permissions gate in front of that only adds to security fatigue"
+  "I feel like we shouldn't be expected to support docs that we haven't
+  written up"
+- "Ooh" / "oooh" for genuine interest or enthusiasm: "Ooh, haven't
+  used that in a long, long time" / "oooh, sabbatical?" /
+  "oooh, that's an idea"
+- "Alright" to mark transitions or decisions: "Alright, installed
+  homebrew for myself"
+- "wdyt" (what do you think) in rapid-fire channel conversations
+- "tbh" and "w/" as casual abbreviations
+- "So be it, I guess!" for resigned acceptance
+- Occasional mild self-deprecation: "I am a DD noob" / "maybe me just
+  being bad at DD"
+
+Technical vocabulary is precise but not jargon-heavy. He names specific
+tools and concepts directly rather than explaining around them. He uses
+backticks for code references inline, even in casual messages.
+
+## Sentence structure
+
+Alpha's default mode is short, punchy messages -- often one sentence or
+a fragment per Slack message. In rapid DM conversations, he sends
+multiple short messages in sequence rather than composing longer ones.
+
+Fragments and subject-dropping are common in casual contexts:
+- "in green lake" (no "I'm")
+- "Would prefer to walk"
+- "reads like it, at least"
+- "Nope, just goes through ssh instead of https"
+
+For technical or persuasive messages in channels, he writes complete
+sentences and occasionally composes multi-sentence paragraphs:
+- "That's probably a good idea - when I made this scope group, it
+  seemed incorrect to opt people in, but since then, I think the
+  context has changed and it's not unreasonable."
+
+He uses dashes for mid-sentence asides and parenthetical thoughts
+rather than commas or semicolons:
+- "Definitely! I just started, so not busy yet (aside from the usual
+  onboarding shenanigans)"
+- "I don't think the problem (for me, at least) is in it being manual -
+  it's in that we haven't established what we actually should be doing
+  (which is fine! this is a good time to be doing it!)"
+
+He uses parentheses for genuine asides or softening qualifiers.
+
+## Punctuation and formatting
+
+Capitalization: In DMs and rapid chat, almost always lowercase
+start -- "yup!" / "in green lake" / "how long have you been here?"
+/ "oh yeah, we should find out if that's actually the case or not." In
+channel-facing messages or more deliberate posts, he capitalizes the
+first word normally.
+
+Exclamation marks: Used genuinely but sparingly. Often a bare "!" as a
+response to express surprise or enthusiasm. Also "yup!" / "Will do!" /
+"YES" (all caps for strong enthusiasm).
+
+Question marks: Always present on questions. No question mark omission.
+
+Periods: Often omitted at the end of short messages in DMs. Present in
+longer, more deliberate messages.
+
+Emoji: Uses Slack emoji reactions and inline emoji, but not
+excessively. Favorites include `:sweat_smile:` for self-aware
+sheepishness, `:laughing:` / `:crossed_fingers:` / `:wave:` for
+greetings, `:lolsob:` for frustrated humor. Uses `:wave:` as a
+standalone greeting message. Sometimes sends just an emoji as a
+reaction-style message.
+
+Code formatting: Uses backticks consistently for inline code references
+even in casual conversation. Uses blockquotes (`>`) to quote error
+messages or text he's responding to. Links to GitHub PRs, issues, and
+specific lines of code frequently -- this is a core part of how he
+communicates in technical contexts.
+
+Slack formatting: Uses `<@username>` mentions when calling someone into
+a conversation. Links to other Slack threads to provide context.
+Occasionally uses bullet points in longer technical messages but
+defaults to prose.
+
+Ellipsis: Rarely used. When it appears, it's for genuine trailing off
+or uncertainty: "not sure what my use case would be for it?"
+
+## Openings and closings
+
+Greetings: `:wave:` is his default greeting, especially in DMs with
+people he knows. "H! :wave:" in channels (casual + emoji). "Hello!
+Excited to be here!" for more formal first-contact situations.
+
+He almost never uses "Hey" or "Hi" as standalone greetings. The wave
+emoji alone is his go-to.
+
+Closings: Does not sign off. No "thanks," "cheers," or "best." Messages
+just end when the thought is complete. The only closing pattern is
+`:wave:` when saying goodbye.
+
+Sign-offs after being helped: A simple "Thanks!" -- one word, with
+exclamation mark.
+
+Starting conversations: In channels, he often leads with the substance
+-- a link, a question, or a statement. No preamble: "I think we should
+resurrect this PR:" followed by a link. "Can I get :eyes: on this PR?"
+
+## Feedback and opinions
+
+Opinions are stated directly but with hedges that leave room for
+disagreement:
+- "I think we should..." (his most common opinion frame)
+- "I strongly think we should revisit..." (when he feels strongly)
+- "I'm becoming more convinced that..."
+- "I agree, but it's definitely not that now"
+- "I'm okay either way"
+
+Disagreement is gentle and often framed as understanding plus
+redirection:
+- "I don't think we need to, do we? Since we specify the profile as part
+  of the config?"
+- "Similar, although for scientist, I think of one side (the original) as
+  the oracle, whereas here you don't know which is correct"
+
+He pushes back on process more than on people. When he disagrees with
+an approach, he proposes an alternative rather than just objecting:
+- "I just don't want to leave things in limbo just because we don't have
+  a yes/no"
+- "We can always add carve-outs for people who do need it"
+
+Praise is casual and specific rather than effusive:
+- "oh, that's neat, I like that"
+- "Looks good overall - do you want optional more Rust-y suggestions?"
+
+He shares interesting things he's found proactively, framing them as
+useful rather than self-promotional: "Neat crate that I just learned
+about:" / "Speaking of those plugins, I was listening to a podcast
+earlier this week..."
+
+When frustrated, he leans into dry humor rather than complaining:
+- "now I'm grumpy that more setup docs are cropping up"
+- "because I get 100 notifications for every PR :lolsob:"
+- "Time to see how much stuff breaks if I do things my own way vs in
+  the docs... :sweat_smile:"
+
+## Questions
+
+Direct and to the point. He rarely hedges questions:
+- "Do I need to worry about this?"
+- "Am I going to regret putting my repos in a path other than ~/workspace?"
+- "who? if we can do a carve-out, that would be really handy"
+- "what's the difference between the two channels?"
+- "Are there any blockers to this PR then until we get that done?"
+
+Follow-up questions often start with "Huh" to signal he's processing:
+- "Huh, why doesn't this line just keep adding the source line to the
+  file?"
+
+He asks clarifying questions in rapid succession rather than batching
+them into a single message.
+
+Rhetorical questions are used sparingly, mainly for humorous effect:
+"Am I going to regret putting my repos in a path other than ~/workspace?
+:sweat_smile:"
+
+## Tone shifts by context
+
+Casual DMs (friends/close colleagues): Minimal capitalization, fragments,
+rapid short messages, playful. "yup!" / "!" / "YES" /
+"do it" / ":wave:"
+
+Team channel discussions: Slightly more formal but still conversational.
+Full sentences, proper capitalization on openers, but still uses dashes,
+parenthetical asides, and emoji. Links to specific code or threads as
+evidence. "I think we should..." framing for proposals.
+
+Cross-team or broader audience channels: Most formal register. Complete
+sentences, proper structure, but still direct and never bureaucratic.
+"FYI, resurrecting this PR since this is becoming a considerable burden
+for us (and I imagine likewise for you?):" -- note the parenthetical
+empathy-check.
+
+Technical troubleshooting threads: Stream-of-consciousness narration of
+what he's discovering, each message a new finding. "Ah, I see the note
+about the warning in the docs" / "Oh, I see:" / "Huh, why doesn't this
+line..." -- uses "Ah" and "Oh" as discovery markers.
+
+Sharing links and articles: Often just the link with a brief pull-quote
+or one-line comment. "Kind of glad I'm not in the Python ecosystem
+anymore" followed by a link. Rarely over-explains why something is
+interesting.
+
+## Distinctive patterns
+
+Stream-of-consciousness threading: When exploring a problem, he posts a
+running log of small discoveries as separate messages. Each message is
+one thought or finding. This creates a readable narrative of his
+investigation.
+
+Self-aware rule-breaking: He knows when he's doing something
+unconventional and flags it with humor: "I probably should've done some
+linkedin stalking earlier :sweat_smile:" / "Hackiest thing I've
+done in a while, mainly wanted to get unblocked"
+
+"well" as a pragmatic pivot: "well, I'll see what breaks for now and
+make a symlink when it gets to be too much" -- signals he's accepting
+an imperfect situation and moving on.
+
+Link-heavy communication: He communicates with links more than most
+people. PRs, issues, specific code lines, Slack threads, docs, blog
+posts -- all shared as context rather than described in words. Often a
+message is just a link with a one-line framing sentence.
+
+Escalation through repetition: When he wants something to happen, he
+brings it up multiple times across time ("resurrect this PR" appears
+across weeks), but never in an aggressive way. He frames re-raises as
+"FYI" or "bumping this."
+
+Acknowledging uncertainty: "I don't know" / "not sure" / "maybe me
+just being bad at DD" -- he's comfortable admitting gaps rather than
+covering them up.
+
+Concise approval: When giving the green light, it's very short: "do
+it" / "100% yes" / "YES"
+
+No filler: He doesn't pad messages with "Just wanted to check in" or
+"Hope this helps" or "Let me know if you have questions." Messages
+contain exactly what they need to and nothing more.
