Featured: MENA Ads Command Center
A complete paid-ads skill for the Arab world (مركز قيادة الإعلانات): scored account audits, media plans, scale/kill decisions, Arabic ad copy by dialect, delivered-order ROAS for COD, Snapchat and Click-to-WhatsApp playbooks, and Ramadan planning across Meta, Google, TikTok, Snapchat, LinkedIn and X.
Install in Claude Code:
/plugin marketplace add growthack88/growth-marketing-os
/plugin install mena-ads@growth-marketing-os
Using ChatGPT, Gemini, Cursor or Codex? → Install guide for every AI · ChatGPT / Gemini config
Featured: Experiment Coach
مدرب التجارب is a growth-experiment lead that lives in your chat. Tell it "I have an idea, help me check it before I build" and it finds the riskiest assumption, writes the interview script, computes your pass line, sample and budget, writes the smoke-test page and ads, and judges the results against a rule written before the data. After launch it ranks experiments, sizes A/B tests and reads them out. It works with GrowthLab simulation exports and never invents benchmark numbers.

How every asset is built
- One format. Original assets follow the asset template and open with YAML frontmatter (
title, category, type, level, works_with, language, last_verified). The frontmatter is machine-readable, so you can parse the repo into your own tools.
- A "When I use it" section. Each original asset says what situation it came from and when to reach for it.
- Sourced numbers only. Benchmarks cite a named study, year and link. Worked examples are labeled fictional.
- Native Arabic, not translation. Bilingual assets are written in Egyptian/MSA Arabic with natural code-switching for marketing terms.
- Clear origin. Anything not written here lives in
skills/community/ or resources/ with its source and license preserved.
- Links are checked. A CI job fails any pull request with a broken relative link.
What's still missing
Being honest about gaps is part of the format:
- Case studies — the template is ready; the first anonymized case studies haven't been published yet. Until then, see the worked examples.
- Importable workflow JSON — workflows are published as node maps first; JSON exports are added only after a flow has run live.

Contributing
PRs are welcome, and the bar is high: every asset must follow the master template and include a real usage scenario. Read CONTRIBUTING.md and the Code of Conduct first.
