What it does

Viral Hook Creator is an agent skill from ognjengt/founder-skills. Creates viral social media hooks using proven psychological patterns and trigger words. Use when user needs attention-grabbing openings for posts, threads, videos, or content.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/hook-patterns.md` and `references/trigger_words.md`).

The repository describes itself as: Claude skills for founders. The licence is MIT.

When your agent uses it

  • User needs attention-grabbing openings for posts

Example prompts

  • “Use the viral-hook-creator skill to create viral social media hooks using proven psychological patterns and trigger words”
  • “/viral-hook-creator”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. MANDATORY: Read Reference Files FIRST
  2. Check for Business Context (Optional)
  3. Analyze Input
  4. Generate Viral Hooks
  5. Format and Verify

What it can do on your machine

Read from SKILL.md and the folder at commit a45931c. 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 (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Viral Hook Creator loads about 1.9k tokens when it runs, and up to ~7.3k if it reads all its reference files. Until then it costs about 49 tokens; SKILL.md has 855 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.3k

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.

Creates viral social media hooks using proven psychological patterns and trigger words. Use when user needs attention-grabbing openings for posts, threads, videos, or content.

Viral Hook Creator

Purpose

Generate 3-5 viral hook options using proven psychological patterns that create curiosity, provide value, and drive engagement. Hooks are optimized for social platforms (X/Twitter, LinkedIn, Instagram, TikTok).


Execution Logic

Check $ARGUMENTS first to determine execution mode:

If $ARGUMENTS is empty or not provided:

Respond with: "viral-hook-creator loaded, proceed with additional instructions"

Then wait for the user to provide their requirements in the next message.

If $ARGUMENTS contains content:

Proceed immediately to Task Execution (skip the "loaded" message).


Task Execution

When user requirements are available (either from initial $ARGUMENTS or follow-up message):

1. MANDATORY: Read Reference Files FIRST

BLOCKING REQUIREMENT - DO NOT SKIP THIS STEP

Before doing ANYTHING else, you MUST use the Read tool to read BOTH reference files. This is non-negotiable:

Read: ./references/hook-patterns.md
Read: ./references/trigger_words.md

What you will find:

  • hook-patterns.md: 18 proven hook patterns with templates, psychology explanations, and the Pattern Selection Matrix
  • trigger_words.md: Four categories of viral trigger words (Insider, Helper, Thinker, Amplifiers)

DO NOT PROCEED to step 2 until you have read both files and have the patterns and trigger words loaded in context.

2. Check for Business Context (Optional)

Check if FOUNDER_CONTEXT.md exists in the project root.

  • If it exists: Read it and use the business context to personalize your output (industry terminology, audience pain points, brand voice, authority metrics).
  • If it doesn't exist: Proceed using defaults from the "Defaults & Assumptions" section.
3. Analyze Input

From the user's requirements, extract:

  • Content topic/theme
  • Target platform (X, LinkedIn, Instagram, TikTok, general)
  • Goal (awareness, education, engagement, conversion)
  • Target audience demographics and psychographics
  • Available social proof (stats, achievements, research)

For any missing information, apply defaults from the "Defaults & Assumptions" section.

4. Generate Viral Hooks

Using the patterns and trigger words you read in Step 1, create hooks:

  1. Select patterns from hook-patterns.md using the Pattern Selection Matrix (match user's goal + platform)

  2. Draft each hook using the pattern template as your starting point

  3. Integrate 1-2 trigger words from trigger_words.md into each hook as you write:

    • Insider words (secretly, revealed, hidden, uncovered, etc.) → exclusivity patterns
    • Helper words (losing, wasting, bleeding, stealing, etc.) → problem/urgency patterns
    • Thinker words (backwards, myth, counterintuitive, paradox, etc.) → contrarian patterns
    • Amplifiers (literally, every, zero, completely, etc.) → any pattern for intensity
  4. Follow all Writing Rules (Core Rules, Pattern-Specific Rules, Platform-Specific Adaptations)

  5. Ensure differentiation - each hook must use a unique pattern

  6. Verify natural integration - trigger words should enhance, not distract

5. Format and Verify
  • Structure output according to Output Format section
  • Complete Quality Checklist self-verification
  • Verify each hook contains trigger words from the reference file

Writing Rules

Hard constraints. No interpretation.

Core Rules
  • Maximum 120 characters for X/Twitter hooks.
  • Maximum 1-2 lines (40-60 characters) for video hooks.
  • Lead with the most interesting element.
  • Create a curiosity gap (promise value but withhold details).
  • Use specific numbers when possible (not "many" but "17").
  • Avoid clickbait that doesn't deliver.
  • Use power words: steal, secret, mistake, never, proven, blueprint.
  • No emojis unless platform-specific (Instagram/TikTok OK, LinkedIn/X avoid).
  • No fluff or filler words.
  • Active voice only.
  • Present tense preferred.
Show full SKILL.md (357 more words)Show less
Pattern-Specific Rules
  • For authority hooks: Lead with credible metric.
  • For list hooks: Use odd numbers (7 > 6, 5 > 4).
  • For story hooks: Start with unexpected outcome.
  • For data hooks: Lead with surprising stat.
  • For cautionary hooks: Lead with mistake/lesson.
Platform-Specific Adaptations
  • X/Twitter: Punchy, contrarian, data-driven, 120 char max.
  • LinkedIn: Professional, achievement-oriented, thought leadership, 40-60 char first line.
  • Instagram: Visual promise, lifestyle-oriented, aspirational, 125 char before "more" cutoff.
  • TikTok: Fast-paced, relatable, trend-aware, 20-30 char on-screen text.
  • General: Versatile, platform-agnostic.

Output Format

Clean and simple. Just hooks with their pattern type as a headline.

markdown
### [Pattern Name]
[Hook text]

### [Pattern Name]
[Hook text]

### [Pattern Name]
[Hook text]

Example:

markdown
### Authority Credibility
I run a 23-person software agency. Here are 5 things I would never do again.

### Data-Driven Insight
I analyzed 1,000 LinkedIn posts. Here are the top 5 patterns that drove engagement.

### Contrarian
Everyone tells you to post daily. I posted 3x per week and got 10x more engagement.

Defaults & Assumptions

Use these unless overridden.

  • Number of hooks: 3
  • Platform: X/Twitter (most restrictive character limit).
  • Goal: Maximize engagement (likes, comments, shares).
  • Audience: General business/entrepreneurship audience.
  • Tone: Professional but conversational (matches most founders).
  • Emotion: Curiosity (safest default for viral content).
  • Format: Thread/post opener (not video hook).

References

These files MUST be read using the Read tool before generating any hooks (see Step 1 of Task Execution):

FilePurpose
./references/hook-patterns.md18 proven hook patterns with templates, psychology, and Pattern Selection Matrix
./references/trigger_words.mdViral trigger word categories (Insider, Helper, Thinker, Amplifiers)

Why both matter: Hook patterns provide psychological structure. Trigger words amplify emotional impact. Patterns alone = good hook. Patterns + trigger words = viral hook (~10x more engagement).


Quality Checklist (Self-Verification)

Before finalizing, verify ALL of the following:

Pre-Generation Check
  • I read ./references/hook-patterns.md before generating hooks
  • I read ./references/trigger_words.md before generating hooks
  • I have the 18 patterns and 4 trigger word categories in context
Pattern & Structure Verification
  • Each hook uses a proven pattern from hook-patterns.md (not made-up patterns)
  • Each hook uses a DIFFERENT pattern (no repetition)
  • Pattern templates were adapted to user context
  • Hooks create genuine curiosity without being misleading
Trigger Word Integration Verification
  • Each hook contains 1-2 trigger words FROM THE FILE I READ
  • Trigger words match pattern types appropriately
  • Trigger words are integrated naturally (not forced)
  • Trigger words enhance emotional impact
Writing Rules Compliance
  • Character limits respected for platform
  • Specific numbers used (not "many" or "some")
  • Active voice throughout
  • No fluff or overused phrases
Final Check

If ANY hook is missing trigger words from the reference file or uses patterns not from hook-patterns.md → revise before presenting.
