How do I install agency-agents?
One git clone. Five minutes including the first paste into Claude Code.
Step 1: Clone the repo
bash
git clone https://github.com/msitarzewski/agency-agents.git
cd agency-agents
The repo is github.com/msitarzewski/agency-agents, MIT licensed, 94.6k stars, built by msitarzewski.
Step 2: Browse the 12 divisions
The agents are organized like a real agency:
| Division | Count | Examples |
|---|---|---|
| Engineering | 28 | Backend, frontend, DevOps, QA |
| Marketing | 27 | Growth Hacker, Twitter, TikTok, LinkedIn, SEO |
| Sales | 9 | Outbound, Discovery, Deal Strategist |
| Design | 7 | UI, UX, brand, motion |
| Paid Media | 8 | Meta Ads, Google Ads, programmatic |
| Specialized | 35 | Vertical-specific agents |
| Product | 5 | PM, research, prioritization |
| Project Mgmt | 5 | Scrum, kanban, dependencies |
| Testing | 8 | Unit, integration, e2e |
| Support | 6 | CX, ticketing, escalation |
| Spatial Computing | 5 | AR/VR, 3D |
| Game Dev | 20+ | Mechanics, balance, narrative |
Step 3: Pick the 5 worth pasting first
For a solo founder running marketing, these five compound fastest:
- Growth Hacker
- LinkedIn Content Creator
- Outbound Strategist
- SEO Specialist
- Twitter Engager
Step 4: Paste an agent into Claude Code or Cursor
Each agent is a single Markdown file with role, expertise, deliverables, and constraints. Open one, copy the whole content, and paste it as the system prompt in your AI editor:
bash
cat marketing/growth-hacker.md | pbcopy # macOS
cat marketing/growth-hacker.md | xclip # Linux
Then in Claude Code, run /agents and create a new agent with that content as the system prompt.
Step 5: Run a real task
Try this with the Growth Hacker agent:
"I sell a $29/mo carousel-generation SaaS to solo creators.
Current MRR: $1,200. Audit my acquisition channels and propose
the next 3 experiments ranked by leverage."
You will get a real plan, not a generic "have you considered SEO" answer — because the system prompt has primed the model with growth-hacker domain expertise.
Step 6: Chain agents for end-to-end workflows
The killer pattern: Outbound Strategist drafts the campaign → Discovery Coach writes the call script → Deal Strategist plans the close → Account Strategist plans expansion. Four agents, one customer journey.
What is agency-agents?
agency-agents is a free, open-source library of 147 specialized AI agents organized into 12 divisions — built like a full digital agency. The maintainer's positioning: "Deep expertise in their domain (not generic prompt templates)" with "Real code, processes, and measurable outcomes".
The repo crossed 94.6k GitHub stars and is MIT licensed — fork it, modify it, ship it commercial.
Is agency-agents really free?
Completely. The agents are Markdown files in a public GitHub repo. No subscription, no API key, no account. You only pay for the underlying model API (Claude, GPT, or whatever you choose).
Compare with Jasper or other "AI marketing platforms" — Jasper Pro starts around $59/month per seat, with limits on words per month. agency-agents charges nothing, runs on whatever model you already pay for, and ships with 27 marketing agents built around real disciplines (Twitter, TikTok, LinkedIn, SEO, Reddit, even Chinese-market specialists like Xiaohongshu and WeChat).
How is agency-agents different from Jasper?
Three differences:
- Open and free. MIT licensed on GitHub. Jasper is closed-source SaaS.
- Specialist depth. Each agent is a domain expert with primer text running 500-2000 words. Jasper templates are short generic prompts.
- Multi-model. agency-agents runs anywhere — Claude, GPT, Gemini, local models on Ollama. Jasper is locked to its own backend.
That said — Jasper has a polished UI, team features, and brand-voice training built in. agency-agents is a power-user tool. The trade is breadth and ownership vs polish.
What's the catch?
- No UI. It is Markdown files. You paste them into Claude Code, Cursor, or whatever AI editor you use.
- You manage your own API costs. Heavy use of Claude Sonnet on a marketing campaign can run $30-100/month. Still cheaper than Jasper Pro.
- Quality varies by agent. Some agents in the 147 are brilliant; some are skeletal. Pick deliberately. The five flagged above are battle-tested.
Bottom line
For solo founders and small teams, agency-agents replaces a $59-200/month marketing-AI subscription with a free GitHub repo. The five agents above (Growth, LinkedIn, Outbound, SEO, Twitter) cover most of what a small team needs. Pair with n8n for execution and NVIDIA Build for free model access, and you have a marketing department that costs less than a coffee.
