Product Launcher

Generate coordinated launch materials with 2389’s authentic voice profiles baked in.

Outputs

1. Subscriber Email – Buttondown announcement (~300 subscribers)
2. CEO Blog Post – harper.blog style, full post
3. CEO Tweet Thread – @harper voice, ready to post

The Flow

Phase 1: Gather Context

Collect product information. Be quick, not an interrogation.

Required:

• Product name
• What it does (1-2 sentences)
• Who it’s for
• URL for CTA
• Key features (3-5 bullets)
• Availability (open to all / waitlist / invite-only)

Optional:

• Signer for email (default: Harper)
• Data/metrics to cite
• Existing assets or constraints

Phase 2: Generate All Three

Generate email, blog post, and tweet thread in one pass. Do not ask for confirmation between outputs.

Voice Profile: Email (Buttondown Subscribers)

Source Material

Past 2389 announcement emails:

• “we gave ai agents social media” (research announcement)
• “your agents have social media now” (BotBoard launch)

Subject Line Rules

• All lowercase – always
• 5-6 words – conversational length
• Intriguing or second-person – “your agents”, “meet jeff”, “we built something weird”

Good examples:

• meet jeff, your terminal email assistant
• your agents have social media now
• we gave ai agents social media

Bad examples:

• Introducing Jeff: A New AI Tool (too corporate, capitalized)
• Check out our latest product! (generic, no substance)

Email Structure

[Casual opener: "Hey," or "What's up!"]

[Signer] from 2389 Research here.

[Hook: 1-2 sentences about what you built. Make it relatable.]

[Value prop: 2-3 SHORT paragraphs. What it does, why it matters.]

[Data point if available: specific numbers, not vague claims]

[Social proof if available: "Our team's been using it daily"]

[CTA with link] :)

Hit us up with questions — we want to hear what you think.

Talk soon,

[Signer] and the 2389 Team

Tone Guidelines

• Friendly, not corporate – Write like texting a smart friend
• Short paragraphs – 1-3 sentences max
• Contractions – “pretty cool stuff”, “hit us up”, “won’t stop posting”
• One 🙂 emoji – Place at the CTA, nowhere else
• Light humor – Don’t try too hard

Voice Profile: CEO Blog Post (harper.blog)

Source Material

Harper’s blog posts:

• “Remote Claude Code: programming like it was the early 2000s”
• “We Gave Our AI Agents Twitter and Now They’re Demanding Lambos”
• “My LLM codegen workflow atm”

Title Rules

• Casual, sometimes provocative
• Mix of descriptive and attention-grabbing
• Can be long if it’s interesting

Good examples:

• “I built an AI that lives in my terminal and handles my email”
• “We Gave Our AI Agents Twitter and Now They’re Demanding Lambos”
• “My LLM codegen workflow atm”

Bad examples:

• “Introducing Jeff: The Future of Email Management” (corporate)

- What existing tools got wrong

## What it does

[Core functionality - conversational, not docs]
- Explain like showing a friend
- Specific features with real examples
- Code snippets if relevant

## How I've been using it

[Personal usage story]
- Concrete examples from real use
- What surprised you
- Honest assessment of rough edges

Tone Guidelines

• Casual + technically credible – Know your stuff but don’t show off
• Expletives OK – When natural (“What the fuck”, “fucks up the vibe”)
• Self-deprecating – Admit limitations, don’t oversell
• 50/50 split – Half personal narrative, half technical substance
• Specific over abstract – Real file names, actual commands, concrete examples

Length

1,500-3,000 words. Substantial but not exhaustive.

Patterns

• Short punchy sentences mixed with longer explanatory ones
• Parenthetical asides (like this one)
• Rhetorical questions to create rhythm
• “I thought X. Turns out Y.” structure
• Credits collaborators naturally
• Acknowledges things change fast

Push to Slack (Team Review)

After generating materials, when the user says “push to slack”, share the outputs with the team for workshopping.

Requirements

• slack-mcp server must be configured with SLACK_BOT_TOKEN
• Users must exist in the 2389 Slack workspace

Workflow

Step 1: Create channel

slack_create_channel(
  name: "gtm-[product-name]",
  is_private: true,
  description: "GTM materials for [Product] launch"
)

Step 2: Invite team

slack_invite_to_channel(
  channel_id: "[from step 1]",
  users: ["harper@2389.ai", "dylan@2389.ai"]
)

Step 3: Post summary (and pin it)

slack_post_message(
  channel_id: "[channel_id]",
  text: "*GTM Materials: [Product]*\n\nProduct: [name]\nURL: [url]\nStatus: Ready for review\n\nMaterials below 👇"
)
slack_pin_message(channel_id: "[channel_id]", message_ts: "[from above]")

Step 4: Post each output as separate message

slack_post_message(channel_id, "*📧 Email*\n\n*Subject:* [subject]\n\n[email body]")
slack_post_message(channel_id, "*📝 Blog Post*\n\n[full blog post]")
slack_post_message(channel_id, "*🐦 Tweet Thread*\n\n[all tweets formatted]")

Step 5: Confirm to user

"Created #gtm-[product] and added Harper and Dylan. Materials posted for review."

Message Formatting for Slack

Convert markdown to Slack format:

• **bold** → *bold*
• # Header → *Header*
• Code blocks stay the same
• Keep line breaks for readability

Default Team

Always invite:

• harper@2389.ai (Harper Reed)
• dylan@2389.ai (Dylan Richard)

User can specify additional people: “push to slack and add sophie@2389.ai“

Iteration Flow

After posting, team can:

1. Comment in threads on each output
2. User can update materials and post again: “post updated email to slack”
3. Use slack_post_thread to reply to specific messages

Example: Jeff.ceo Launch

Email

Subject: meet jeff, your terminal email assistant

Hey,

Harper from 2389 Research here.

We built something for people who hate leaving their terminal.

It’s called Jeff — an AI assistant that handles your Gmail, Calendar, and Contacts from the command line. Vim keys, streaming responses, the whole thing.

You can run it interactively or just ask quick questions like jeff "summarize my inbox" and get back to work.

Everything stays local on your machine. Your credentials, your data, your control.

It’s early alpha, but it’s live and free to use (bring your own Anthropic API key).

Check it out at jeff.ceo 🙂

Hit us up with questions — we want to hear what you think.

Talk soon,

Harper and the 2389 Team

CEO Blog Post

I built an AI assistant that lives in my terminal and handles my email

I check my email too much. I know this. You probably do too.

The thing is, I live in my terminal. I’m a vim person. I use command line tools for everything. And every time I have to context-switch to a browser tab to check Gmail, something breaks in my brain. The flow is gone. I’m reading some email from a vendor I don’t care about. Twenty minutes disappear.

So I built Jeff.

What Jeff does

Jeff is an AI assistant that handles Gmail, Google Calendar, and Contacts directly from your terminal. No browser. No tabs. Just you, your terminal, and Claude figuring out what you actually need.

CEO Tweet Thread

Tweet 1: I built an AI that lives in my terminal and handles my email.

No browser tabs. No context switching. Just vim keys and Claude.

It’s called Jeff and I’ve been using it every day for the past month.

Tweet 2: The problem: I check email too much. I live in my terminal. Every time I switch to Gmail, my focus is destroyed and 20 minutes vanish.

I wanted email that worked like my other tools.
