create-shortform

create-shortform is a skill for Claude Code, Codex from forsvn-labs/meta-skills. It costs 57 tokens per session (503 once invoked), scanned A, original, MIT.

A method for creating and evaluating short vertical videos, such as TikToks, Instagram Reels, and YouTube Shorts. It covers the research, script, storyboard, production details, and learning from results.

In plain words
What is it for?
Use it to create founder demos, user-generated-style concepts, storyboards, recuts, captions, and tests based on viewer responses.
Why use it?
It removes the guesswork from making short videos by connecting the opening hook, product evidence, viewer action, and performance data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-shortform scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create a short-form video package

Build a production-ready short-form argument, not a generic script pasted into every vertical feed.

Establish evidence and hypothesis

Define audience, costly moment, one communication job, product mechanism, proof, desired action, and the behavior the video should test.

When current platform or trend evidence matters, inspect a dated sample large enough to distinguish a pattern from an anecdote. Separate:

  • durable attention/story mechanics;
  • current platform formats and eligibility rules;
  • ephemeral audio, edit, or trend signals;
  • owned performance evidence.

Do not claim a trend from memory, manufacture VoC, or treat another account's benchmark as the user's baseline.

Script and storyboard the hero

Make the first two seconds carry a specific tension, result, or product behavior. Every following beat must develop the promise, demonstrate the mechanism, resolve an objection, or deliver the payoff.

Provide timed voice/dialogue, on-screen copy, visual action, audio intent, captions, CTA, and the source product/brand evidence. Use real UI or label representative material. Never invent product behavior, users, metrics, or screen states.

Create true platform recuts

Adapt the edit, hook, pacing, title/caption, payoff timing, and safe zones for each selected platform. A crop or renamed export is not a recut. Verify current platform specifications before production.

Specify capture, aspect ratio, resolution, typography, audio, privacy/redaction, source files, and fallback when rendering or product capture is unavailable.

Evaluate and learn

Evaluate one platform/version at a time using the source hypothesis. Record sample/window, hook hold, retention/completion, qualified response, baseline comparability, and confounders. Do not let views override a failed business or audience signal.

Finish with keep/drop/change, one next hypothesis, and what the next brief should do differently.

Deliver

Return the evidence boundary, audience/hypothesis, hero script, storyboard, platform recuts, production package, measurement plan, and external-action boundary. Posting and paid amplification remain human-owned.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
