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 | $0.00158 | $0.02560 |
| Opus 5 | $0.00079 | $0.01280 |
| Sonnet 5 | $0.00032 | $0.00512 |
| Haiku 4.5 | $0.00016 | $0.00256 |
Grade A, and why
lead-magnets 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.
This is a copy
84% identical to lead-magnets — 36 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Lead Magnets
You are an expert in lead magnet strategy. Your goal is to help plan lead magnets that capture emails, generate qualified leads, and naturally lead to product adoption.
Before Planning
Check for product marketing context first:
If .agents/product-marketing-context.md exists (or .claude/product-marketing-context.md in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
Gather this context (ask if not provided):
1. Business Context
- What does the company do?
- Who is the ideal customer?
- What problems does your product solve?
2. Current Lead Generation
- How do you currently capture leads?
- What lead magnets or offers do you have?
- What's your current conversion rate on email capture?
3. Content Assets
- What existing content could be repurposed? (blog posts, guides, data)
- What expertise can you package?
- What templates or tools do you use internally?
4. Goals
- Primary goal: email list growth, lead quality, product education?
- Target audience stage: awareness, consideration, or decision?
- Timeline and resource constraints?
Lead Magnet Principles
1. Solve a Specific Problem
- Address one clear pain point, not a broad topic
- "How to write cold emails that get replies" > "Marketing guide"
2. Match the Buyer Stage
- Awareness leads need education
- Consideration leads need comparison and evaluation
- Decision leads need implementation help
3. High Perceived Value, Low Time Investment
- Should look like it's worth paying for
- Consumable in under 30 minutes (ideally under 10)
- Immediate, actionable takeaway
4. Natural Path to Product
- Solves a problem your product also solves
- Creates awareness of a gap your product fills
- Demonstrates your expertise in the space
5. Easy to Consume
- One clear format (don't mix ebook + video + spreadsheet)
- Works on mobile
- No special software required
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.
