What is viral-hook-generator?

A writing skill that creates 24 LinkedIn opening lines, called hooks, from a topic, idea, rough note, or weak post. It provides two versions for each of 12 patterns, ranks three choices, and adds a follow-up second line for those choices.

Use it to develop LinkedIn hooks from rough ideas or existing posts, compare alternatives, and refine the opening of a social-media post.

A post can lose readers before they reach its main point. This gives several tested opening approaches and helps select the strongest candidates.

Token cost

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	$0.00132	$0.03005
Opus 5	$0.00066	$0.01503
Sonnet 5	$0.00026	$0.00601
Haiku 4.5	$0.00013	$0.00300

Security

Grade A, and why

viral-hook-generator 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.

Viral Hook Generator

Purely Personal · by Daniel Paul

Read ALL reference files before generating anything:

/references/voice-dna.md, Daniel's 5 hook archetypes, ICP snapshot, banned words
/references/human-writing-standards.md, Hook Quality Test (5 points), AI blacklist
/references/copywriting-frameworks.md, framework context for each hook type
/references/design-system.md, brand tokens

STEP 0 — CONTEXT CHECK (always first, never skipped)

Look for the participant's context, in this priority order:

BUSINESS-BRAIN.md — project root, Project Knowledge, or attached to the chat. The single source of truth. If present, its Voice DNA, ICP, hook archetypes, and banned words OVERRIDE the Daniel Paul defaults in /references/voice-dna.md.
If no brain: the individual foundation documents — icp-[name].md, voice-dna-[name].md, positioning-[name].md, messaging-[name].md, rule1-[name].md, personal-story-[name].md, business-inbox-[name].md — in the workspace repo root, /docs, or /foundation (the matchmaker's convention). Use them the same way.
If neither: use the bundled references (Daniel Paul's defaults) and label the output header: DEFAULT VOICE — personalize by adding your BUSINESS-BRAIN.md to this project.

Never ship a default where a participant value exists. Never re-ask for the reader when the brain's ICP already describes them.

WHEN RUNNING HEADLESS (routine / scheduled)

No human is in the loop. Never wait for a choice:

Skip the Step 1 clarifying question. Take the reader from the brain's ICP; if none exists, state the assumed reader in one line labeled DEFAULT — assumed and build anyway.
The ranking already picks the winner: lead the output with the Rank 1 hook, named as the pick, with the one-sentence "Why #1" reasoning. Do not end with a question.

Routine output contract: the deliverable is a Gmail DRAFT (never send) with email-safe HTML (inline styles only, no external scripts, no GSAP) or clean plain text, and/or a file committed to the repo when the routine prompt says so. Interactive mode keeps the full HTML file behavior per references/html-output-templates.md.

What ships with it

10 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.

Changes

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.
