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 | $0.00169 | $0.04996 |
| Opus 5 | $0.00084 | $0.02498 |
| Sonnet 5 | $0.00034 | $0.00999 |
| Haiku 4.5 | $0.00017 | $0.00500 |
Grade A, and why
crossing-the-chasm 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 10d 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 — 464 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 It synthesizes the book's core ideas with modern startup practice, surfaces where frameworks are outdated or incomplete, and integrates perspectives from adjacent disciplines.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.
Crossing the Chasm
"The point of greatest peril in the development of a high-tech market lies in making the transition from an early market dominated by a few visionary customers to a mainstream market dominated by a large block of customers who are predominantly pragmatists in orientation." - Geoffrey Moore
Should You Use This Skill?
Is your product targeting enterprise buyers (>$10K deals, multi-stakeholder)?
├─ YES → Continue to next question
└─ NO → Pure consumer / PLG / marketplace?
├─ Pure consumer (TikTok, gaming) → SKIP this skill entirely
├─ PLG SaaS (Slack, Notion, Figma) → Use positioning + whole product concepts only; for adoption strategy, see **$100M Leads**
├─ Marketplace (Airbnb-like) → Two-sided dynamics don't map to TALC; use **Blue Ocean Strategy** for market creation
└─ AI-native (Cursor, Claude) → Adoption patterns unprecedented; use **Four Steps to Epiphany** for customer discovery, this skill for enterprise positioning only
Do you have at least 10 paying customers or repeatable early-adopter revenue?
├─ YES → Continue
└─ NO → You're still in Customer Discovery/Validation. Use **four-steps** and **mom-test** first. Come back when you have real traction.
Are you currently in early market (visionaries buying)?
├─ YES → This skill is for you
└─ NO, you're already mainstream → You're past the chasm. Use Inside the Tornado concepts (bowling alley, tornado, main street)
Do you have months/years for strategy execution?
├─ YES → Full framework applies
└─ NO (<6 months runway) → Apply tactical bits (positioning, beachhead) without multi-year choreography
The Core Insight
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.

crossing-the-chasm is a skill published in the GitHub repository getagentseal/founder-playbook (556 stars, last pushed 1mo ago), licensed MIT. It adds 169 tokens to every session and 4,996 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.
