What it does
Viral Hook Writer is an agent skill from Ootto-AI/claude-content-skills. Write scroll-stopping hooks for a short-form video (the first 1-3 seconds). Use when the user says "hook", "reel hook", "opening line", "scroll stopper", "first three seconds", "TikTok hook", or "how do I start this video".
Its SKILL.md is about 530 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 Media & Creative, covering Video production. It works with TikTok. The repository describes itself as: Free, copy-paste Claude skills that run your content growth factory — turn ideas + your NotebookLM memory into scroll-stopping Instagram reels. By Ootto. The licence is MIT.
When your agent uses it
- The user says hook
- First three seconds
- How do I start this video
Example prompts
- “reel hook”
- “opening line”
- “scroll stopper”
- “/viral-hook-writer”
What it can do on your machine
Read from SKILL.md and the folder at commit 5263be7. 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
Links to these hosts (documentation or services it may open):
ootto.ai
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
Viral Hook Writer loads about 529 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 171 words of instructions outside code blocks.
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 Hook Writer
Generate a batch of scroll-stopping hooks for a reel — the make-or-break first 1-3 seconds.
When to use
You have a reel topic but the opening is weak. The hook is ~80% of whether anyone watches — this gives you options to test.
What you'll need
The topic, who it's for (your audience/niche), and the one thing you want them to feel or do. Optional: your brand voice and a few hooks that have worked for you before.
Instructions
Collect the topic and audience, then run this prompt:
You are my short-form video hook writer. Topic: [topic]. Audience: [who it's for]. Desired reaction: [stop scrolling / save it / comment / DM me].
Write 10 hooks for the first 1-3 seconds. Use a spread of proven angles:
- Bold claim / contrarian take
- "If you [situation], do this"
- Mistake / "stop doing X"
- Number + payoff ("3 ways to…")
- Curiosity gap / open loop
- Result-first ("I went from X to Y")
- Question that names the pain
Rules: under 12 words each, spoken-language, no fluff, no hashtags. For each hook add a 3-5 word on-screen text version. Mark the 3 you'd test first and say why in one line.Obsidian memory tip: If you've connected your Obsidian vault (Filesystem MCP — see Ootto's setup guide), point Claude at your notes of past reels — "use the hooks that performed best in my vault as the pattern." Hooks grounded in your winners beat generic ones.
Tip: Always generate 10 and test 2-3. The hook you love is rarely the one that wins.
