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.

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 | $0.00097 | $0.01852 |
| Opus 5 | $0.00048 | $0.00926 |
| Sonnet 5 | $0.00019 | $0.00370 |
| Haiku 4.5 | $0.00010 | $0.00185 |
Grade A, and why
lead-magnet-brainstorm 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 13d 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 Brainstorm
Cold emails with a concrete free offer outperform "book a call" asks by 3-10x. This skill helps the user find an offer they can actually deliver.
Why this exists
Most cold emails fail the "why should I reply?" test. The answer "because you might need our product" is not compelling. The answer "because we'll send you a free audit that'll save you money whether or not you buy from us" is.
A good lead magnet is:
- Cheap to deliver at scale (ideally automated)
- Genuinely valuable to the prospect (they'd pay for it, or it saves them obvious time/money)
- Demonstrates your competence (so buying becomes the natural next step)
When to use
- During
/icp-onboardingwhen the user can't answer the "what can you give away" question - When copywriting and the CTA feels weak
- When reply rates are <1% and the problem is "nobody cares about my ask"
Steps
1. Intake — 4 questions
Ask one at a time:
- What do you sell, in one sentence? (Use their ICP onboarding answer if you have it.)
- What's the #1 problem your best customer had BEFORE buying from you? (This is the north star — the magnet should ease this problem.)
- What could you do for a prospect in under 30 minutes that they'd pay $100 for? (The crux. Push back on "nothing" — there's always something. If they're an SEO agency, they could audit a page. A copywriter could rewrite a subject line. A dev shop could review one function.)
- Any legal / regulatory restrictions on what you can promise or give? (Financial advice, medical claims, securities — know before proposing.)
2. Pick from the lead magnet archetype library
Match their business to one or more archetypes:
A. The free audit / diagnostic
- "Free 5-minute audit of your [thing]" — works for agencies, consultants, dev shops
- Delivery: you or AI runs a quick check, send back a 1-page report
- Examples: "I noticed your site doesn't have X, here's why that's costing you Y"
- CTA: "Want me to run the full audit? Free, takes 5 min of your time."
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.

lead-magnet-brainstorm is a skill published in the GitHub repository growthenginenowoslawski/coldoutboundskills (702 stars, last pushed 25d ago), licensed MIT. It adds 97 tokens to every session and 1,852 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
