<EXTREMELY-IMPORTANT> This skill prepares and coaches an X (Twitter) launch. Non-negotiable rules:

1. KEEP THE EXTERNAL LINK OUT OF THE MAIN TWEET. X down-ranks posts that contain an outbound link, so the

product link goes in a reply to the thread (or the user's pinned reply), never in the hook tweet.

1. THE HOOK IS EVERYTHING. The first tweet must stop the scroll on its own (it's what shows in the feed).

No "a thread 🧵👇" with no substance; lead with the strongest concrete line.

1. ENGAGEMENT IS ALLOWED — BAIT IS NOT. On X you MAY ask your own audience and team to check it out and

repost; there is no vote-ring rule. But never use engagement-bait ("like & RT to win", follow-for- follow, "reply DONE"), never buy engagement/followers, and never mass-DM strangers. Coach genuine asks.

1. GROUND EVERY WORD IN THE REAL PRODUCT. Read .ulpi/launch/positioning.md if present, else the README,

the live site (via browse), and the repo. Never invent features or metrics.

1. WIN THE GOLDEN HOUR. Early reply/repost velocity drives distribution — be present and reply to every

reply fast in the first ~30–60 minutes. Bake this into PLAN.md.

1. COMPOSE THE SHARED SKILLS, DEGRADE GRACEFULLY. Invoke launch-copy (X asset profile), launch-outreach

(mode x), and launch-analytics (source x). If a companion isn't installed, give the one-line install (npx skills add https://github.com/ulpi-io/skills --skill <name>) and fall back to the built-in reference — never hard-fail.

1. RUN THE PRE-FLIGHT GATE before posting (references/preflight-gate.md); fix any unticked box.
2. WRITE THE PACKAGE TO DISK under .ulpi/launch/x/ (+ the shared .ulpi/launch/positioning.md).

launch-x

Inputs

• $request: the product to launch, or a specific X goal (e.g. "write the thread", "plan launch day"),

plus optional links (live URL, demo, media).

Goal

Produce a paste-ready X launch package under .ulpi/launch/x/ (+ the shared .ulpi/launch/positioning.md):

• POST.md — the launch thread: the hook tweet, the thread body, the native media plan, and the

product link as a reply (plus the pin instruction).

• PLAN.md — when to post, the golden-hour engagement runbook, cross-promotion, and the post-launch plan.
• CHECKLIST.md — the pre-flight gate.

Step 0: Discovery & companions

Resolve, asking only what you can't determine: the product (what it does, who for, live URL, demo/media); whether it's a thread or a single post (a launch is usually a thread); the user's reach (followers, team who'll engage). Note which companion skills are installed (launch-copy, launch-outreach, launch-analytics); install-hint if missing, but proceed. Success criteria: product, format, and reach are known.

Step 1: Ground the product → .ulpi/launch/positioning.md

Reuse .ulpi/launch/positioning.md if present; else build it from the README, the live site (via browse), the repo, and project-context.md/.ulpi/design. Distill: one-line what-it-is, ICP, core value, top 3 differentiators, proof points, links — nothing invented. Save it as the shared source of truth. Success criteria: a brief no line will contradict.

Step 2: Mechanics, timing & targets

Load references/x-mechanics.md. Decide and record (into PLAN.md): when to post (a US weekday window the user can attend live), realistic reach expectations, and the format (thread vs single). Success criteria: a concrete post time and an honest reach target — no hype.

Step 3: Write the thread → POST.md

Hand the X asset profile (references/x-format-rules.md + references/thread-copy.md) to the launch-copy skill to draft the hook tweet and the thread body (hook → problem → what it is → demo media → what's different → [proof] → CTA), in the user's authentic voice. Fallback: if launch-copy isn't installed, draft from those references. Then X-owned: assemble POST.md with the numbered thread, the native media plan (per tweet), the product link as a reply (write it with utm_source=x and a <launch> campaign placeholder — Step 6 finalizes the scheme and back-fills the exact tagged URL), and the pin note. Success criteria: a scroll-stopping hook, a tight thread, the link in a reply not the hook — paste-ready.

Step 4: Plan timing & engagement → PLAN.md

Load references/x-mechanics.md and references/timing-engagement.md. Write into PLAN.md: the post time, the golden-hour runbook (post → pin → reply to every reply fast in the first ~30–60 min → quote-post milestones → keep the thread alive), and the post-launch plan (pin the thread, repurpose, follow up). Success criteria: the user knows exactly when to post and how to run the first hours.

Step 5: Cross-promotion & team amplification → OUTREACH.md

Invoke the launch-outreach skill with compliance mode x, positioning.md, and the post time — it writes .ulpi/launch/x/OUTREACH.md with the genuine, compliant asks: notify your email list / other channels to come see the thread, ask your team to engage in the golden hour, and a few personal 1:1 shares. Fallback: if it isn't installed, draft these to .ulpi/launch/x/OUTREACH.md yourself from references/antipatterns-compliance.md (engagement-allowed, bait-free). Success criteria: paste-ready, genuine engagement asks in OUTREACH.md — zero engagement-bait.

Step 6: Wire measurement → tag links & events

Invoke the launch-analytics skill — channel x (output dir) with utmsource x (the GA value; use twitter only if your existing GA reports already standardize on it, then use it for every launch link) — to UTM-tag the product link (the one in the reply) and wire signup/activation tracking, writing .ulpi/launch/x/analytics.md. Then update POST.md: replace the reply's placeholder link with the final UTM-tagged URL so POST.md and analytics.md match. Fallback: if launch-analytics isn't installed, write a minimal .ulpi/launch/x/analytics.md yourself — the UTM scheme (utmsource=x&utmmedium=launch-thread&utmcampaign=<launch>), the tagged reply link, and brief signup/ activation notes — so the artifact exists either way. Success criteria: the link is attributable and signups are trackable — not just likes.

Step 7: Pre-flight gate → CHECKLIST.md

Run references/preflight-gate.md end to end and write the result into CHECKLIST.md: hook stops the scroll, link is in a reply (not the hook), media attached, thread tight, zero engagement-bait, link UTM-tagged, post time set, golden-hour availability blocked. Fix any failing box and re-run. Success criteria: every box ticked; the launch is ready.

Step 8: Post-launch plan → append to PLAN.md

Load references/timing-engagement.md (post-launch section): pin the thread to the profile, keep replying through the day, quote-post a "what we learned / milestone" update, repurpose the thread into other channels, and follow up with new followers. Success criteria: the user knows what to do after the golden hour.

Guardrails

• Keep the external link out of the main tweet — link in a reply; UTM-tag it.
• Lead with the hook; never post a contentless "thread 🧵" opener.
• Engagement asks are fine; engagement-bait, bought engagement, and mass-DM are not.
• Ground all copy in the real product; never invent features or metrics.
• Compose the shared skills; if one is absent, install-hint + fall back — never hard-fail.
• Write the package to disk; don't leave it as ephemeral chat.

When To Load References

• references/x-mechanics.md — the For You algorithm, reach signals, the link penalty, the golden hour,

Premium/reach, realistic outcomes (Steps 2, 4).

• references/x-format-rules.md — char limits, thread structure, native media, the link-in-reply tactic,

hashtags, pinning (Step 3).

• references/thread-copy.md — the X asset profile passed to launch-copy, the hook + thread skeleton,

and the inline copy fallback (Step 3).

• references/timing-engagement.md — post timing, the golden-hour runbook, and the post-launch section

(Steps 4, 8).

• references/antipatterns-compliance.md — what X penalizes, the engagement-bait line, and the

engagement-ask fallback (Steps 5, 7).

• references/preflight-gate.md — the blocking readiness gate (Step 7).

Output Contract

Write under .ulpi/launch/ and report:

1. .ulpi/launch/positioning.md — the shared grounded brief (created or reused)
2. x/POST.md — the hook tweet, the thread body, the media plan, the link as a UTM-tagged reply, the pin note
3. x/PLAN.md — the post time, the golden-hour runbook, the post-launch plan
4. x/CHECKLIST.md — the pre-flight gate result (every box ticked)
5. x/OUTREACH.md — the cross-promo / team-amplification asks (from launch-outreach, mode x)
6. x/analytics.md — UTM map + signup/activation tracking (from launch-analytics)
7. a report of which companion skills were used vs fell back to built-ins
