A setup guide for Mozaiks, a software platform for building AI-powered applications, from a fresh checkout. It explains the supported development tiers and required local tools.

Use it to install or check Docker, Python and Node, configure an OpenAI API key, and start the local backend, frontend and reference app.

It gives developers a clear path through dependencies, environment variables and local verification before they start working.

SkillSpector: 3 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

Token cost

What it costs to keep this loaded

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	$0.00025	$0.00914
Opus 5.5	$0.00010	$0.00366
Sonnet 5.5	$0.00005	$0.00183
Haiku 4.5	$0.00003	$0.00091

Security

Grade A, and why

setup 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 1mo 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.

Tier System

Mozaiks supports four development tiers:

Tier	Use Case	What's Included
engine	Headless AI API	Workflows only, no UI
chat	Chatbot builders	Workflows + chat UI
integrated	SaaS builders	+ modules + event bus + auth
full	Product builders	+ admin portal + full management surfaces

For more info on tiers: /init-project or /add-feature skills.

Prerequisites to Check

Run these commands and verify versions:

Docker 24+ and Compose v2+
Python 3.11+
Node 20.19+ or 22.12+ (Vite 8 requirement), npm 9+

If anything is missing, help them install it first.

Canonical Local Contributor Path

For this repo, the default local contributor experience is:

Studio host backend on http://localhost:8000
web_shell/ frontend on http://localhost:3000
factory_app/app as the first-party builder/reference app bundle when no external app workspace is selected

Setup Steps

1. Environment Variables

# Copy .env.example to .env
cp .env.example .env  # or Copy-Item on Windows

Set OPENAI_API_KEY=sk-... in .env. If $ARGUMENTS contains an API key, use it. Also set LLM_PRIMARY_API_TYPE=openai and DEFAULT_LLM_MODEL=gpt-5-nano in .env: .env.example ships Gemini values for both, but builds call OpenAI only, and the runtime would send gemini-2.0-flash to OpenAI.

2. Python + Repo Dependencies

python -m venv .venv
# Activate: .\.venv\Scripts\Activate.ps1 (Windows) or source .venv/bin/activate (Unix)
python -m pip install --upgrade pip
python -m pip install -e ".[dev]"

3. Frontend Dependencies

npm --prefix web_shell install

4. Start the Default Local Dev Stack

Preferred path in this repo:

.\scripts\run-studio.ps1

That starts the Studio host backend and the web_shell frontend together.

5. Verify

Open http://localhost:3000/apps
Check backend health at http://localhost:8000/health
Run .\scripts\smoke-studio-local.ps1 for the full local Studio smoke
Confirm the frontend is loading the first-party builder/reference app bundle from factory_app/app

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.

setup is a skill published in the GitHub repository BlocUnited-LLC/mozaiks (24 stars, last pushed yesterday), licensed MIT. It adds 25 tokens to every session and 914 once invoked, about $0.0001 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 2026-08-30.
