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.

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 | $0.00092 | $0.01423 |
| Opus 5.5 | $0.00037 | $0.00569 |
| Sonnet 5.5 | $0.00018 | $0.00285 |
| Haiku 4.5 | $0.00009 | $0.00142 |
Grade A, and why
viral-hook-creator 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Viral Hook Creator
Purpose
Two modes over the same knowledge base:
- GENERATE: produce 3-5 strong hook options for a topic.
- GRADE: score a hook the user pastes, explain why it works or doesn't, and hand back stronger rewrites.
Hooks are optimized for short-form platforms (X/Twitter, LinkedIn, Instagram, TikTok). Never auto-send or auto-publish. Output is a draft.
Step 0: Determine Mode
- If the user pasted a hook (or a few) and is asking whether it's good / to score / strengthen / rewrite it → GRADE mode.
- Otherwise → GENERATE mode.
- If
$ARGUMENTSis empty and no hook was pasted, respond"viral-hook-creator loaded, proceed with additional instructions"and wait.
Step 1: Load the Library FIRST (both modes)
BLOCKING REQUIREMENT: do this before generating or grading anything.
Read the bundled reference files. These ship with the skill and always work offline:
./references/hook-patterns.md: 19 proven hook patterns with psychology and a selection matrix./references/trigger_words.md: four categories of viral trigger words (Insider, Helper, Thinker, Amplifier)
Optional richer source: if you keep a fuller hooks library as a Notion page (structures, swipe file, interest piques, performance data), set its page ID here and fetch it as the primary source, falling back to the bundled files if the fetch fails:
- Notion page ID:
390f3b91-c73d-81a8-99d6-d77e7f63753e
Swap that ID for your own page, or delete this block to run purely off the bundled files. Do not proceed until the library is loaded.
GENERATE Mode
1. Analyze input
Extract: topic/theme, target platform, goal (awareness, education, engagement, conversion), audience, available social proof. For anything missing, use Defaults & Assumptions.
If FOUNDER_CONTEXT.md exists in the project root, read it and personalize with that business context.
2. Select and draft
- Pick patterns using the selection matrix (match goal + platform). Each of the 3-5 hooks uses a DIFFERENT pattern.
- Draft each hook from the pattern template, adapted to the user's topic.
- Integrate 1-2 trigger words per hook, matched to the pattern.
- If the goal is conversion or a full video, also name the structure each hook would open (if your library has structures).
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

viral-hook-creator is a skill published in the GitHub repository nataliacorrea03/claude-code-skills (4 stars, last pushed 3mo ago), licensed MIT. It adds 92 tokens to every session and 1,423 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-31.
