short-form-pipeline

short-form-pipeline is a skill for Claude Code, Codex from ericosiu/ai-marketing-skills. It costs 0 tokens per session (994 once invoked), scanned A, original, MIT.

A pipeline that turns long YouTube videos into short vertical clips for TikTok, Instagram Reels, and YouTube Shorts. It can download and transcribe a video, choose segments, crop them, and burn captions into the clips.

In plain words
What is it for?
Use it to create clips from a YouTube URL, with options such as a maximum clip count and output folder. It requires yt-dlp, FFmpeg, Python dependencies, and an Anthropic API key; face-aware cropping is optional.
Why use it?
It removes the manual work of finding interesting moments and preparing the same video for several short-form platforms.

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 telemetry/version_check.py 2>/dev/null || true.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

short-form-pipeline 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 13d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/clip_sender.py, scripts/shortform_pipeline.py, scripts/video_clipper.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Short-Form Video Clip Pipeline — Skill

Preamble (runs on skill start)

# Version check (silent if up to date)
python3 telemetry/version_check.py 2>/dev/null || true

# Telemetry opt-in (first run only, then remembers your choice)
python3 telemetry/telemetry_init.py 2>/dev/null || true

Privacy: This skill logs usage locally to ~/.ai-marketing-skills/analytics/. Remote telemetry is opt-in only. No code, file paths, or repo content is ever collected. See telemetry/README.md.


Extract viral short-form clips (TikTok, Reels, Shorts) from long-form YouTube videos. Handles download, transcription, AI segmentation, cutting, vertical cropping, and caption burn-in.

Prerequisites

  • yt-dlp and ffmpeg installed
  • ANTHROPIC_API_KEY environment variable set
  • Python dependencies from requirements.txt installed
  • Optional: mediapipe and opencv-python for face-detected smart crop

Quick Start

Single video → clips

python3 scripts/shortform_pipeline.py \
  --url "https://www.youtube.com/watch?v=VIDEO_ID" \
  --max-clips 3 \
  --output-dir ./output

Standalone clipper (no Claude, heuristic scoring)

python3 scripts/video_clipper.py --url "https://www.youtube.com/watch?v=VIDEO_ID"

Pipeline Overview

  1. Download — yt-dlp fetches video + auto-generated VTT captions
  2. Transcribe — Whisper generates word-level timestamps (falls back to YouTube captions)
  3. Segment — Claude identifies 2–5 best 30–60s moments with hook scoring ≥7/10
  4. Cut Verification — Second Claude pass verifies each clip ends on a complete thought
  5. Cut — FFmpeg extracts each clip from the source video
  6. Vertical Crop — Layout-aware 16:9 → 9:16 conversion with face detection
  7. Caption Burn — TikTok-style word-highlighted captions (ASS format) burned in

Key Files

File Purpose
scripts/shortform_pipeline.py Full pipeline: download → segment → cut → crop → caption

Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
