short-form-converter

short-form-converter is a skill for Claude Code, Codex from nicepkg/ai-workflow. It costs 61 tokens per session (2,120 once invoked), scanned A, original, MIT.

A repurposing tool that turns long videos into short vertical clips for TikTok, YouTube Shorts, and Instagram Reels. It identifies notable moments, suggests openings, and adapts scripts to the shorter format.

In plain words
What is it for?
Creating Shorts, TikToks, and Reels from longer videos, including clip selection, hooks, and vertical-format planning.
Why use it?
Finding usable moments and reshaping them for several platforms takes time. This provides a starting point for selecting clips and rewriting them for short-form viewing.

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-converter 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 yesterday.

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 Converter

Transform long-form content into viral short-form clips.

Viral Moment Identification

What Makes a Clip Viral-Worthy?

✅ STRONG VIRAL INDICATORS:
1. Emotional peak - Surprise, shock, joy, anger
2. Unexpected twist - Plot reversal, revelation
3. Valuable insight - "Aha moment", key takeaway
4. Relatable moment - "This is so me" content
5. Controversial take - Debate-starting opinion
6. Satisfying conclusion - Before/after, completion
7. Funny moment - Genuine humor, reaction

❌ WEAK CLIP MATERIAL:
- Long setup without payoff
- Inside jokes requiring context
- Technical explanations without visual
- Slow-paced segments
- Content requiring full video context

Clip Selection Process

STEP 1: Timestamp key moments from long video
- Mark ALL emotional peaks
- Note all "quotable" statements
- Identify visual highlights
- Flag unexpected moments

STEP 2: Score each moment (1-10)
- Hook potential: Does it grab in 1 second?
- Standalone value: Makes sense without context?
- Engagement likelihood: Will people comment/share?
- Platform fit: Right vibe for TikTok/Shorts/Reels?

STEP 3: Select top 3-5 moments for clips
- Prioritize variety (don't all same type)
- Ensure each has different hook angle

0:00-0:03 | HOOK: "The [result] trick nobody knows"
0:03-0:08 | CONTEXT: "When you need to [problem]..."
0:08-0:40 | CORE STEPS: Just the 3 most important steps
0:40-0:45 | CTA: "Follow for more [topic]"

CUT: All intro fluff, slow explanations, tangents
KEEP: Core value, best tips, before/after

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.
