What it does
Viral Copywriting is an agent skill from revfactory/harness-100. A specialized skill for the copywriter agent covering viral copywriting. Provides scroll-stopping hook patterns, platform-specific copy structures, emotion triggers, and CTA psychology. Use for 'viral copy,' 'hook writing,' 'caption writing,' 'SNS copy,' and similar topics.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Writing & Content, covering Copywriting. The licence is Apache-2.0.
When your agent uses it
- Caption writing
- Tasks that involve Copywriting
Example prompts
- “viral copy,”
- “hook writing,”
- “caption writing,”
- “/viral-copywriting”
What it can do on your machine
Read from SKILL.md and the folder at commit 8e8d35c. 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.
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 Copywriting loads about 1.2k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 446 words of instructions outside code blocks.
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.

Viral Copywriting — Viral Copywriting Methodology
Specialized viral copy knowledge used by the copywriter agent when writing SNS posts.
Why Viral Copy Is Different
SNS copy must stop the scroll within 0.5 seconds. Unlike blogs or emails where you retain someone who has started reading, here you must stop someone who is passing by.
15 Scroll-Stop Hook Patterns
Shock/Provocation Category
| # | Pattern | Template | Example |
|---|---|---|---|
| 1 | Counter-Intuitive | "[Conventional wisdom] is wrong" | "Hard workers succeed? It is the exact opposite" |
| 2 | Number Shock | "Did you know [surprising number]?" | "73% of professionals don't know this" |
| 3 | Provocation | "[Taboo statement]" | "Networking is a waste of time" |
| 4 | Warning | "If you're doing [action], stop right now" | "If you check email first thing in the morning, stop" |
Curiosity Category
| # | Pattern | Template | Example |
|---|---|---|---|
| 5 | Incomplete | "[Situation] happened. The result..." | "I deleted an account with 1M followers. After that..." |
| 6 | Secret | "What [subject] never tells you" | "The one thing successful founders don't share" |
| 7 | How-To | "How I achieved [amazing result]" | "How I tripled my salary in 6 months" |
| 8 | List | "[N] ways to [topic] (the last one is key)" | "5 ways to cut your marketing budget (number 3 is a game-changer)" |
Emotion/Empathy Category
| # | Pattern | Template | Example |
|---|---|---|---|
| 9 | Confession | "Honestly speaking..." | "Honestly, my first 3 years were all failures" |
| 10 | Empathy | "You're [universal struggle], right?" | "Anyone else dread Monday every Sunday night?" |
| 11 | Transformation | "[Before] -> [After]" | "6 months ago: burnout -> Now: 4-day work week" |
Authority/Trust Category
| # | Pattern | Template | Example |
|---|---|---|---|
| 12 | Credentials | "What I learned from [experience/track record]" | "One thing I learned from consulting 300 brands" |
| 13 | Quote | "[Famous person] said: '...'" | "The one email Elon Musk sent to his employees" |
| 14 | Case Study | "The strategy behind [specific result]" | "From $0 to $3M monthly revenue. With this one strategy" |
