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 | $0.00242 | $0.02683 |
| Opus 5.5 | $0.00097 | $0.01073 |
| Sonnet 5.5 | $0.00048 | $0.00537 |
| Haiku 4.5 | $0.00024 | $0.00268 |
Grade A, and why
hacking-growth 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 8d 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hacking Growth
Sean Ellis's Hacking Growth methodology — the systematic, cross-functional approach to growth that replaced "growth hacks" with growth science. Built from Hacking Growth: How Today's Fastest-Growing Companies Drive Breakout Success (Currency/Crown, 2017, co-authored with Morgan Brown), Ellis's public talks and podcast appearances (including Lenny's Podcast, 2024), his Substack (2025-2026), the Breakout Growth Podcast, and his career as the first marketer at Dropbox, Eventbrite, and LogMeIn.
This skill helps your agent think about growth as systematic experimentation across the full customer journey — not as acquisition tactics, not as "growth hacks," and not as marketing under a new name. Ellis coined the term "growth hacking" in 2010 to describe a cross-functional, data-driven discipline. The skill maintains that distinction.
When this skill activates
Use this skill when the user is:
- Setting up a growth team (structure, roles, rituals, cadence).
- Choosing a North Star metric and building the growth equation around it.
- Prioritizing growth experiments using ICE scoring.
- Running high-tempo testing (the four-step analyze-ideate-prioritize-test cycle).
- Measuring product-market fit with the "must-have" survey (the Sean Ellis Test).
- Designing experiments across acquisition, activation, retention, referral, or monetization.
- Building a growth process from scratch at a post-PMF company.
- Diagnosing why a growth process isn't producing results (wrong metric, pre-PMF experimentation, siloed team, low test velocity).
- Asking about the difference between growth hacking and marketing.
- Working on activation optimization — getting users to the "aha moment."
- Building referral or viral mechanics into their product.
- Asking about growth in the AI era — freemium word-of-mouth, AEO (answer engine optimization), advocacy loops.

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.

hacking-growth is a skill published in the GitHub repository marcos-sponton/frameworks-as-skills (1 stars, last pushed 9d ago), licensed MIT. It adds 242 tokens to every session and 2,683 once invoked, about $0.0010 per session on Opus 5.5. 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 2026-10-08.
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.
codex-autoresearch
Run repeated, measured Git experiments toward a numeric target; keep improvements and revert failures. Use for autonomous optimization or managing an autoresearch run, not one-shot edits.
clipboard
Copy text to clipboard with optional rich formatting. Triggers on "copy to clipboard", "copy that", "pbcopy", "copy formatted", "copy rich text".
