Launch Tweet

This skill helps craft social media announcements for product launches. The principles here are platform-aware — what works on X doesn't copy-paste to LinkedIn — but the core goal is the same: stop the scroll, communicate value, and drive action.

Single launch tweet

The single tweet is your most important launch asset. Even if you're doing a full thread, this tweet needs to work on its own because most people will only see it.

Structure

[Strong first line — what you launched, framed as value]

[1-2 sentences expanding on what it does / why it matters]

[Media: video, GIF, or screenshot — attached, not linked]

Rules

1. First line does all the work. It must make clear you're launching something and why anyone should care. No "excited to announce" or "after months of hard work" — lead with the product value.

2. Media in the first tweet. Always. A tweet with a video or image gets dramatically more engagement than text alone. Attach the media directly — don't link to YouTube or an external page.

3. No link in the first tweet. Platform algorithms penalize external links. Put your link in a reply or the second tweet of a thread. If you must include a link and want the preview card to render, keep the entire tweet (including URL) under 280 characters.

4. Specificity over hype. "Now you can build voice apps in 5 lines of code" beats "Revolutionary new API." Numbers, concrete use cases, and before/after comparisons stop the scroll.

Examples

Good first lines:

• "Introducing [Product]: [concrete thing it does]"
• "[Product] now does [specific capability]. Here's what that means →"
• "You can now [action] with [product]. No [previous friction point] required."
• "We just shipped [feature]. [One-line proof point or result]."

Weak first lines (avoid):

• "Excited to announce..." (buries the value)
• "After months of hard work..." (nobody cares about your timeline)
• "Thread 🧵" (penalized, provides no value)
• "Big news!" (empty hype)

Launch threads

Threads work for Tier 1 and some Tier 2 launches where you have enough substance to fill 4-8 tweets without padding.

Thread structure

Tweet 1: The hook Same rules as the single tweet. This must work standalone. Include your best media (video or key screenshot). No link.

Tweets 2-4: Value props and proof Each tweet covers one value prop or proof point. Include supporting media — screenshots, GIFs, short demo clips. Visual breaks every 2-3 tweets keep people scrolling.

Tweet 5-7 (optional): Social proof or use cases Customer quotes, benchmarks, comparisons, example use cases. This is where you make the value concrete.

Final tweet: Call to action + link This is where the link goes. Be specific about what happens when they click: "Try it free →", "See the docs →", "Watch the full demo →".

Thread principles

• 5-8 tweets is the sweet spot for launch content. Threads over 15 see sharp engagement drop-off.
• Each tweet must provide value on its own. People drop off at every tweet — don't build toward a punchline at tweet 7.
• Visual breaks matter. Alternate between text-heavy and media-heavy tweets.
• No filler tweets. If you can't fill 5 tweets with substance, do a single tweet instead.

Cross-platform adaptation

The same announcement needs different treatment on each platform. Don't just copy-paste.

X/Twitter

• Concise, punchy, visual-first
• Thread format for bigger launches
• Hashtags: use sparingly (1-2 max) or skip entirely
• Best engagement: mornings and early afternoon (audience-dependent)

LinkedIn

• Longer-form, more narrative
• Open with a hook but can be more contextual than X
• Works well for B2B launches and technical products
• Include 3-5 line breaks for readability (LinkedIn truncates after ~3 lines, so the first 3 lines must earn the "see more" click)
• Tag relevant people and companies
• No hashtag stuffing — 3 max, at the end

BlueSky

• Similar to X in format and tone
• Slightly more technical/niche audience (as of 2025-2026)
• Threads work well here
• Less algorithmic amplification — rely more on community sharing

Threads

• More casual, conversational tone
• Shorter posts tend to work better
• Cross-posting from Instagram helps distribution
• Less business/tech-native audience — frame for broader appeal

Hacker News

• Not a "post" in the social media sense — it's a submission with a title
• Title should be factual and specific, not hype-y: "Show HN: [Product] – [what it does in plain terms]"
• The discussion thread matters more than the submission itself
• Be ready to answer technical questions honestly and in detail
• Don't ask people to upvote — it will backfire

Writing process

When drafting launch social copy, follow this sequence:

1. Start with the messaging brief (from launch-strategy). If there's no brief, ask for: product/feature name, target audience, primary value prop, and 2-3 secondary value props.

2. Write the X/Twitter version first. The character constraint forces clarity. If the value prop doesn't fit in a tweet, the messaging isn't sharp enough.

3. Expand to a thread if the launch warrants it (Tier 1 or substantial Tier 2). Map each secondary value prop to a tweet.

4. Adapt for other platforms. LinkedIn gets more context and narrative. BlueSky stays concise. Hacker News gets a factual title.

5. Draft multiple first-line options. The first line is the highest-leverage sentence. Write 3-5 variants and pick the one that best balances clarity, specificity, and scroll-stopping power.

Common mistakes

• Linking in the first tweet. It tanks reach. Always put links in a reply or later in the thread.
• No media. Text-only launch tweets underperform dramatically. Even a screenshot is better than nothing.
• Burying the value. Three sentences of preamble before saying what you launched. Lead with the product.
• Same copy everywhere. Each platform has different norms. Copy-paste looks lazy and performs poorly.
• Thread padding. If you're adding tweets just to make the thread longer, cut them. Short and strong beats long and diluted.
• Forgetting the CTA. Every launch post needs a clear next step for the reader. What do you want them to do?

Companion skills

• launch-strategy — messaging brief that feeds the social copy
• launch-email — email subject lines follow the same "first line" craft as tweets
• launch-video — the demo video or GIF that goes in the tweet (attached, not linked)
• launch-distribution — when and where to post, and how to amplify
• launch-metrics — track which social posts drive signups via UTMs
