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 | $0.00284 | $0.04094 |
| Opus 5 | $0.00142 | $0.02047 |
| Sonnet 5 | $0.00057 | $0.00819 |
| Haiku 4.5 | $0.00028 | $0.00409 |
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 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Crossing the Chasm
Geoffrey Moore's staged theory of high-tech market development. Distilled from Crossing the Chasm (1991; 3rd edition, 2014 — canonical), Inside the Tornado (1995), Living on the Fault Line (2000), Dealing with Darwin (2005), Escape Velocity (2011), Zone to Win (2015), plus his ongoing LinkedIn Pulse essays (multi-post cadence in 2024–2026), his own blog at geoffreyamoore.com, the frameworks Chasm Institute teaches (Hierarchy of Powers, Category Maturity Life Cycle, 9-Point Strategy Checklist), and podcast appearances including Lenny's Podcast, January 2024.
This skill helps you think in stages, not just recite the chasm metaphor. It's opinionated because Moore is opinionated: each stage has its own playbook, and mixing playbooks kills the campaign. The winning strategy for the bowling alley is the wrong strategy for the tornado. Position based on where the market actually is, not where marketing wishes it were.
When this skill activates
Use this skill when the user is:
- Working on go-to-market strategy for a discontinuous-innovation product (SaaS, AI/ML, dev tools, infrastructure, deep tech) where adoption behavior differs across customer segments.
- Picking a beachhead segment or deciding "which vertical do we go after first?"
- Diagnosing why traction with early adopters isn't converting into a repeatable mainstream motion ("pragmatists won't buy").
- Sequencing adjacent verticals to expand into (bowling-alley thinking).
- Deciding whether the market has entered a tornado (standardize, ship horizontal) or is still in the bowling alley (verticalize, ship whole product).
- Planning post-tornado / main-street plays — share-of-wallet, customer intimacy, +1 niche modifications.
- Sizing a whole-product gap — what integrations, services, partners, and references does a pragmatist need before they'll buy?
- Building a compelling reason to buy (CRTB) for a pragmatist audience — what broken process is currently costing the customer real money?
- Applying Zone to Win for an incumbent managing a disruption (Performance / Productivity / Incubation / Transformation).
- Using Hierarchy of Powers (Category / Company / Market / Offer / Execution) to diagnose growth-source problems.
- Applying Core vs. Context from Dealing with Darwin to an innovation portfolio.
- Positioning around the Digital Systems Maturity Model (Systems of Record → Engagement → Analytics → Intelligence → Disruption).
- Reasoning about where AI (predictive, generative, agentic) sits on the adoption curve for a specific use case, using Moore's 2024–2026 essays as anchor.

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 marcos-sponton/frameworks-as-skills (1 stars, last pushed 1mo ago), licensed MIT. It adds 284 tokens to every session and 4,094 once invoked, about $0.0014 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 2026-08-31.
Other skills, from other repositories
acquire-skills
Find and install skills for what you're doing — tech or reasoning gaps. Matches activity and tech context to relevant skills. Use when entering unfamiliar tech, stuck on a reasoning challenge, or no skill fits.
find-skills
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
endpoint-discovery
Discovers URLs, endpoints, and paths from web applications using katana, gospider, and gau. Use when needing to enumerate application endpoints, find hidden paths, gather historical URLs, or map web application structure during reconnaissance.
param-miner
Discover hidden HTTP parameters in web applications that could reveal hidden functionality or vulnerabilities. Use when testing APIs, when looking for hidden parameters like admin or debug, or when the user mentions parameter discovery.
git-workflow
This skill should be used when the user asks to "create git commit", "manage branches", "follow git workflow", "use Conventional Commits", "handle merge conflicts", or asks about git branching strategies, version control best practices, pull request workflows. Provides comprehensive Git workflow guidance for team…
daily-paper-generator
Use when the user asks to generate daily paper digests on a general topic. This skill supports both arXiv and bioRxiv (or either one), then produces structured Chinese/English summaries for selected papers.
