Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.00506 |
| Opus 5 | $0.00028 | $0.00253 |
| Sonnet 5 | $0.00011 | $0.00101 |
| Haiku 4.5 | $0.00006 | $0.00051 |
Grade A, and why
ab-hook-tester 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 12d ago.
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.
What it actually says
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

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.
