When your agent uses it

  • Repurposing videos
  • Creating Shorts from long videos
  • Planning multi-platform content

Example prompts

  • “/short-form-converter”

What it can do on your machine

Read from SKILL.md and the folder at commit d167b41. 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

Short Form Converter loads about 2k tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 142 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~2k

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.

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

Platform-Specific Adaptations

TikTok Optimization
- Trending sounds matter A LOT
- Fast pacing (cut every 2-3 seconds)
- Text-heavy (assume sound off)
- Casual, authentic vibe
- Strong community engagement (duets, replies)
- Hashtags: Mix trending + niche
YouTube Shorts Optimization
- Can be more polished than TikTok
- Original audio often works better
- Clear value proposition
- Works well with educational content
- Less sound-dependent than TikTok
- #Shorts hashtag helps discovery
Instagram Reels Optimization
- Slightly more curated aesthetic
- Trending audio helps but less critical
- Strong visual composition
- Carousel-style content works
- Story crosspost strategy
- Hashtags in caption, not on video

Editing Tips for Conversion

✅ DO:
- Add captions (85% watch muted)
- Use jump cuts to remove dead space
- Add b-roll or visual variety
- Include text overlays for key points
- Match platform's native style
- Trim the fat ruthlessly

❌ DON'T:
- Just crop and post (feels lazy)
- Keep long pauses/transitions
- Use horizontal clips (except split-screen)
- Ignore platform-specific features
- Post same exact clip everywhere
- Forget the CTA

Short-Form Checklist

Before posting each clip:

  • Hook in first 1-2 seconds
  • Captions/text added
  • Vertical format (9:16)
  • No dead space/pauses
  • Clear CTA at end
  • Relevant hashtags
  • Thumbnail/cover selected (if applicable)
  • Links in bio updated
  • Platform-optimized (native features used)
