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 | $0.00304 | $0.04283 |
| Opus 5 | $0.00152 | $0.02142 |
| Sonnet 5 | $0.00061 | $0.00857 |
| Haiku 4.5 | $0.00030 | $0.00428 |
Grade A, and why
play-bigger 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Play Bigger — Category Design
Al Ramadan, Dave Peterson, Christopher Lochhead, and Kevin Maney's discipline of category design — creating and dominating a new market category, so the assistant can help the user become the Category King (or Queen) that captures the ~76% of category market cap that goes to the category leader. Distilled from Play Bigger (HarperBusiness, 2016), the founders' Time-to-Market-Cap (TTMC) research, and — critically — the ten years of post-book refinement that lives in the Category Pirates Substack (Lochhead + Eddie Yoon + Nicolas Cole + Bri Clark) and their subsequent books: Snow Leopard, A Marketer's Guide to Category Design, The Category Design Toolkit, The 22 Laws of Category Design, and the 2025 prequel The Existing Market Trap: Escaping the 13 Deadly Sins.
This skill helps the assistant think inside the method — loud, evangelical, "different not better", CEO-owned, ecosystem-obsessed — not just recite the 2016 book. It is opinionated because the authors are opinionated: category design is not positioning, not branding, not messaging, not storytelling. It's a strategic discipline that decides which category exists, names it, plants it in the market's mind, and builds the ecosystem that makes the category real.
When this skill activates
Use this skill when the user is:
- Trying to figure out whether to create a new category or compete inside an existing one.
- Working on a Point of View (POV) — the CEO-owned category story.
- Planning a Lightning Strike — the concentrated market-conditioning event that plants the category.
- Naming a new category (the 2–3-word test).
- Diagnosing why a great product is stuck losing to incumbents inside a legacy category (the "Existing Market Trap").
- Mapping or building the category ecosystem (analysts, partners, developers, missionaries).
- Debating "we should build a better X" vs. "we should build a different X, in a new category."
- Post-pivot, when the market keeps categorizing the company as something old.
- Designing the Data Flywheel that will make the category defensible in year 5+.
- Escaping the AI-era version of the trap — being framed as an "assistant" or "copilot" to an incumbent instead of a category of your own.
- Composing category design with an existing positioning / narrative / cascade the user already has.

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.

play-bigger is a skill published in the GitHub repository marcos-sponton/frameworks-as-skills (1 stars, last pushed 1mo ago), licensed MIT. It adds 304 tokens to every session and 4,283 once invoked, about $0.0015 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.
