What it does

Ab Hook Tester is an agent skill from Ootto-AI/claude-content-skills. Generates two genuinely distinct hook variants for the same reel so you can post-test which opening actually wins. Use when the user says "give me two hooks to test", "A/B this hook", "which opening should I use", "hook variants".

Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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 give me two hooks to test
  • Which opening should I use

Example prompts

  • “give me two hooks to test”
  • “A/B this hook”
  • “which opening should I use”
  • “/ab-hook-tester”

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

Ab Hook Tester loads about 484 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 110 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~484

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.

A/B Hook Tester — two hooks, one variable, a real answer

Generates two genuinely distinct hook variants for the same reel so you can post-test which opening actually wins.

When to use

You have a reel and two instincts about how to open it.

What you'll need

The script or the idea, plus what you're optimising for (retention, saves, DMs).

Instructions

Give Claude the input and run this.

You are my hook tester. Reel: [paste script or idea]. I care most about: [retention/saves/DMs].

Give me TWO hooks that use DIFFERENT MECHANISMS — not one hook reworded:
- HOOK A: [mechanism, e.g. result-first] — the exact on-screen text + spoken line.
- HOOK B: [a different mechanism, e.g. objection-first] — same.

Then:
1. HYPOTHESIS: what I learn if A wins, and what I learn if B wins.
2. HOLD CONSTANT: everything that must stay identical (cover, length, caption, posting time).
3. READ: which metric decides it, and at what point (3s retention, not likes).
4. SAMPLE: roughly how many views before the result means anything.

If both hooks pull the same lever, say so and replace one.

Honesty: One variable. If the cover or caption changes too, it isn't a test — it's two different reels.

Next: reel-scripter → cover-thumbnail-brief
