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 | $0.00162 | $0.03174 |
| Opus 5 | $0.00081 | $0.01587 |
| Sonnet 5 | $0.00032 | $0.00635 |
| Haiku 4.5 | $0.00016 | $0.00317 |
Grade A, and why
storybrand 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 11d 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 — 287 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Note: This skill is independent analysis and commentary, not a reproduction of the original text. It synthesizes the book's core ideas with modern startup practice, surfaces where frameworks are outdated or incomplete, and integrates perspectives from adjacent disciplines. For the full argument and context, read the original book.

Should You Use This Skill?
Is your marketing underperforming despite a good product?
|-- YES --> Can customers explain what you do in one sentence?
| |-- NO --> THIS SKILL. You have a clarity problem.
| +-- YES --> Do they understand why they should care?
| |-- NO --> THIS SKILL. You're not connecting to their story.
| +-- YES --> Problem is elsewhere. Try Traction (channels) or
| Obviously Awesome (competitive positioning).
+-- NO --> Is your product actually good?
|-- NO --> Fix product first (Lean Startup / Four Steps).
+-- YES --> Are customers finding you?
|-- NO --> Use Traction. Distribution problem, not messaging.
+-- YES but not converting --> THIS SKILL.
The Core Insight
Customers don't buy the best products. They buy the products they can understand the fastest.
The human brain is a survival processor. It has two jobs:
- Help us survive and thrive
- Conserve calories (mental energy)
If a customer hits your website and burns too many calories trying to figure out what you offer, they leave. It doesn't matter how good your product is. Noise kills sales.
Story is the antidote to noise. Story is the most powerful tool for organizing information because the human brain is hardwired for narrative. The SB7 Framework forces your messaging into a story structure that every brain already knows how to process.
The Mistake Every Brand Makes
WHAT BRANDS DO: WHAT BRANDS SHOULD DO:
Position themselves as the HERO Position themselves as the GUIDE
Talk about their own journey Talk about the customer's journey
Lead with features and history Lead with the customer's problem
Use insider jargon Use simple, clear language
Make the customer work to understand Make the offer obvious in 5 seconds
What ships with it
4 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.

storybrand is a skill published in the GitHub repository getagentseal/founder-playbook (562 stars, last pushed 1mo ago), licensed MIT. It adds 162 tokens to every session and 3,174 once invoked, about $0.0008 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.
