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 | $0.00102 | $0.04446 |
| Opus 5 | $0.00051 | $0.02223 |
| Sonnet 5 | $0.00020 | $0.00889 |
| Haiku 4.5 | $0.00010 | $0.00445 |
Grade A, and why
seedance-viral-hook 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.

The Attention Economy: Why 2 Seconds
- 0-2s: The gate. If 50%+ bounce here, the video dies. If 90% stay, the algorithm promotes.
- 2-5s: Hook confirmation. Brain decides: worth my time or not.
- 5-15s: Engagement peak. Emotional beats, reveals, payoffs land here.
- 15s+: Retention cliff. Most viral videos are under 15 seconds.
Videos with 80%+ completion get 2-3x algorithmic reach. Your hook determines everything.
The Hook Arsenal: 12 Battle-Tested Patterns
1. Pattern Interrupt — Break Reality
| Technique | Mechanism | Prompt Template |
|---|---|---|
| Physics Break | Objects defy gravity, water flows up, time reverses | "Open with [object] defying physics — floating upward, sliding in reverse, freezing mid-air. Camera steady, treating impossible action as mundane. First 0.8s shows normal expectation, 0.8-2s breaks it. No music, only ambient sound emphasizing the wrongness." |
| Scale Warp | Familiar object at impossible size | "Extreme wide shot: [tiny object — coin, key, pen] scaled to building size in landscape. Human figure provides scale reference at base. Drone-style camera slowly pushing forward. Overcast lighting, photorealistic. Viewer spends 2s processing scale." |
| Color Bomb | Grayscale world gets sudden saturation | "Scene begins fully desaturated — gray, lifeless, muted. At 1.2s, single element ignites with saturated color [neon pink/electric blue/gold]. Color bleeds outward across frame over 0.8s. Hard bass hit synced to color moment." |
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.

seedance-viral-hook is a skill published in the GitHub repository rediumvex/ai-video-generator-claude (361 stars, last pushed 1mo ago), licensed MIT. It adds 102 tokens to every session and 4,446 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
