What it does

Newsletter Promo is an agent skill from charlie947/motion-graphics-skills. Turn a newsletter edition into a 12-20 second promo clip for LinkedIn, Instagram or X that drives people to read and subscribe. Hook question, three proof frames from the edition, then the newsletter name and where to read it. Use when someone says "promo for my newsletter", "trailer for this edition", "get people to my Substack", "teaser video" or "promote this issue".

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Newsletters. It works with LinkedIn, Instagram and Substack. The repository describes itself as: 13 Claude Code skills for launch-grade motion graphics. Every frame is code. No After Effects, no video generator. The licence is MIT.

When your agent uses it

  • Someone says promo for my newsletter
  • Trailer for this edition
  • Get people to my Substack
  • Promote this issue

Example prompts

  • “promo for my newsletter”
  • “trailer for this edition”
  • “get people to my Substack”
  • “/newsletter-promo”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Ask for four things, then wait
  2. Structure (15 seconds)
  3. Build brief (paste into Claude Code)
  4. Export and post

What it can do on your machine

Read from SKILL.md and the folder at commit dfc4284. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Newsletter Promo loads about 630 tokens when it runs. Until then it costs about 97 tokens; SKILL.md has 224 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~97
When it runs · the whole SKILL.md, loaded when a task matches
~630

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Turn a newsletter edition into a 12-20 second promo clip for LinkedIn, Instagram or X that drives people to read and subscribe. Hook question, three proof frames from the edition, then the newsletter name and where to read it. Use when someone says "promo for my newsletter", "trailer for this edition", "get people to my Substack", "teaser video" or "promote this issue".

Newsletter promo, built in code

A promo does one job: make someone want the full edition. Show the best bits, never the whole thing.

Before you start: read brand.md and MOTION.md if they exist. If not, run brand-intake first, or ask for hex codes, a font and a logo file. Never call a result on-brand without them.

Step 1: Ask for four things, then wait

  1. The edition link or the full text. Read it before anything else.
  2. The hook. The one question or promise the edition answers. If none is given, propose three from the edition's own lines and wait for a pick.
  3. Three proof frames. Real images, charts or clips from the edition. Attached files only.
  4. The ending card, word for word: newsletter name, where to read it, and an optional subscriber count with its source.

Step 2: Structure (15 seconds)

TimeFrame
0-3sThe hook, big. A question works better than a statement.
3-11sThree proof frames, about 2.5s each, each with a 3-5 word label.
11-15sNewsletter name, "Read it free at [URL]", held still.

Step 3: Build brief (paste into Claude Code)

Build one self-contained HTML file called index.html: a 15-second promo at [WIDTH] x [HEIGHT] for my newsletter edition, using only the files I attached.

Hook (0-3s): "[HOOK]" in bold condensed type, [TEXT] on [BG], key words in [ACCENT].
Proof (3-11s): my three attached images in this order, each held about 2.5 seconds with a slow push-in and this label: [LABEL 1], [LABEL 2], [LABEL 3].
End card (11-15s): "[NEWSLETTER NAME]" and "Read it free at [URL]". Hold still, readable on a phone.

Banned: typewriter text, glow, bouncing, gradients on text, any claim or number not in my brief.

Build rules: every frame from the time alone, window.seek(seconds), wait for seek when the URL has ?render. Capture one frame per shot and check every label is readable at phone size.

Step 4: Export and post

Export 1080 x 1350 for LinkedIn and 1080 x 1920 for Stories and Reels. Put the edition link in the first line of the caption, not only the comments.
