A tool for thinking up and creating free content that attracts potential customers and encourages them to join an email list. A lead magnet is something useful people receive in exchange for their contact details.

Use it to develop checklists, guides, templates, or other free resources, along with their titles, hooks, and written content.

It helps solve the problem of offering the wrong free resource or creating ideas that do not fit the audience, brand, or paid service.

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	$0.00251	$0.09761
Opus 5.5	$0.00100	$0.03904
Sonnet 5.5	$0.00050	$0.01952
Haiku 4.5	$0.00025	$0.00976

Security

Grade A, and why

lead-magnet 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 2mo 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.

Lead Magnet Ideation + Build

The best lead magnets aren't about what you want to give away. They're about what your prospect desperately wants to consume -- and how that consumption naturally leads them toward your paid offer.

This skill generates lead magnet concepts that actually convert. And then it builds them.

Read ./brand/ per _system/brand-memory.md

Follow all output formatting rules from _system/output-format.md

Brand Memory Integration

This skill reads brand context to ensure every lead magnet concept aligns with the user's positioning, speaks to their actual audience, and sounds like their brand. It also checks for existing campaigns and lead magnets to avoid duplication.

Reads: voice-profile.md, positioning.md, audience.md (all optional)

On invocation, check for ./brand/ and load available context:

Load voice-profile.md (if exists):
- Match the brand's tone and vocabulary in all lead magnet copy
- Apply voice DNA to titles, hooks, and body content
- A "direct, proof-heavy" voice writes different hooks than a "warm, story-driven" voice
- Show: "Your voice is [tone summary]. Lead magnet copy will match that register."
Load positioning.md (if exists):
- Use the chosen positioning angle to inform the lead magnet's frame
- The positioning determines how the lead magnet bridges to the paid offer
- Use differentiation points to ensure the lead magnet is unique vs competitors
- Show: "Your positioning angle is '[angle]'. Concepts will build on that frame."
Load audience.md (if exists):
- Know who this lead magnet is for: awareness level, sophistication, pain points
- Match format complexity to audience preference (video people vs readers vs doers)
- Use audience language in hooks and titles
- Show: "Writing for [audience summary]. Awareness: [level]."
Check for existing lead magnets (if ./campaigns/*/brief.md or ./brand/assets.md references a lead magnet):
- If a lead magnet already exists, note it and ask whether to create a new one or iterate
- Show: "Found existing lead magnet: '[name]'. Want to create a new one or improve this?"

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.
