create-imessage-mockup
Need a fake iMessage screenshot for an ad, social post, video scene, or product mockup.
Reading signals from an audience
What it does
Generate iMessage screenshots that look like real iOS captures — correct bubbles with tails, typing indicators, timestamps, "Delivered" captions, group avatars + sender names, keyboard chrome, and an optional iPhone 15 Pro bezel with Dynamic Island and status bar.
What it can touch
Includes 5 scripts
Your AI can run these when the skill is used — on your computer in a coding tool (which asks first unless you have told it not to), or in the AI’s own sandbox in Claude and ChatGPT.
How we know
Found in the skill’s folder: generate.js, render.js, screenshot.js, templates/icons.js….
Installs other software
Following it will install packages (npm, pip, brew or similar). Those come from their own publishers, not from this skill.
How we know
The SKILL.md contains package-install commands.
1 smaller thing worth knowing
Contains commands that delete or overwrite. Usually legitimate — listed so nothing is hidden.
How we know
Contains commands that delete or overwrite — tests/run-all.sh line 7. Read 2026-10-05, commit e6048bf.
tests/run-all.sh, line 7 ↗No serious risk pattern found
Launch7’s automated check read all 22 text files in this skill and matched none of its serious risk patterns. This is not a guarantee: a check like this can miss new or disguised tricks, and the author can change the files after the check.
How we know
Read 2026-10-05, commit e6048bf by pipeline/trust/analyze.py — 40+ patterns for hidden text, prompt injection, downloads that run, credential access and more. It reads; it never runs the skill.
Recently maintained
Its repository has had changes recently.
How we know
Last push to gooseworks-ai/goose-skills: 2026-10-04 (1 days before the scan).
Read automatically from the skill’s own files on GitHub on 5 Oct 2026. Launch7 does not run or manually review skills: this lists what the check saw, and nothing here means “safe”. How we check
Add it to your AI
Partly. Upload it in Claude’s settings — the instructions work; the scripts need the full folder.
Built in your browser from the SKILL.md on GitHub — nothing passes through Launch7.
In Claude, open Customize → Skills, press +, then Create skill → Upload a skill, and choose the .zip.
Make sure code execution is switched on (Settings → Capabilities). Skills need it.
Start a new chat and ask for the job in your own words — Claude picks the skill up when it fits.
This skill ships 5 scripts beside its instructions. The download here is the SKILL.md alone — enough for the instructions, not for the parts that run code. Use the command route, or take the full folder from the repository.
How Claude does this: support.claude.com · checked 28 Sep 2026 · “Supported” means documented by the vendor; Launch7 has not run it end to end
