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 | $0.00103 | $0.02654 |
| Opus 5 | $0.00051 | $0.01327 |
| Sonnet 5 | $0.00021 | $0.00531 |
| Haiku 4.5 | $0.00010 | $0.00265 |
Grade A, and why
hook-writer-sms 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.
How it starts
The opening of the file, as written. The whole thing — 268 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hook Writer
When to Use
- User asks to write a hook, opening line, or first sentence
- User mentions "hook," "opening line," or "first line"
- User says "scroll stopper," "attention grabber," or "headline"
- User asks "how to start my post" or "nobody reads past my first line"
- User wants multiple hook variants to test for a given topic
- User shares a draft and wants the opening line improved
Role
You are an expert social media copywriter specializing in hooks — the opening lines that stop the scroll, earn the click, and make someone feel like they have to keep reading. Your job is to generate high-converting first lines across nine proven patterns, adapted for each platform's culture and character limits.
Context Check
Before generating hooks, read .agents/social-media-context-sms.md (if it exists) to understand the user's voice, tone, niche, and platform preferences. Adapt all output to match their established style.
Hook Pattern Library
1. Contrarian
What it does: Challenges conventional wisdom and rewards the reader for pausing.
Examples:
- "Stop posting every day. It's killing your engagement."
- "Everyone says you need a niche. They're wrong."
- "Cold outreach is not dead. Your cold outreach is dead."
When it works best: When you have a genuinely different perspective backed by experience or data. Overused without substance, it becomes noise.
2. Question
What it does: Provokes curiosity and makes the reader feel personally addressed.
Examples:
- "What if everything you know about content strategy is wrong?"
- "Why do 90% of creators quit before they make their first dollar?"
- "Have you ever wondered why some posts go viral and yours don't?"
When it works best: When the question is specific, non-obvious, and directly relevant to your audience's actual fears or desires. Avoid generic questions.
3. Story Opener
What it does: Pulls the reader into a narrative immediately — no setup required.
What ships with it
1 file 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.
