Contributing to Mozaiks

Mozaiks is open source under the MIT license. This section is for people working on the framework itself — changing runtime code, adding factory workflows, improving the Console, or maintaining the release pipeline.

If you are building an app with Mozaiks, you do not need this section. Start with Getting Started instead.

Where to start

  • Local Dev Setup — source checkout, editable install, and how to run the builder stack from repo
  • Architecture — how the runtime, app bundle contract, module system, workflows, and frontend fit together
  • Agent Bootstrap Prompt — hand a task to Claude Code, Cursor, or Copilot with the repo-aware bootstrap prompt
  • Contributor Guidance Readiness — current skill coverage, routing map, deferrals, and guidance validation tests

Release and Maintenance

Repo Structure

The canonical repo layout is documented in ARCHITECTURE.md.

Key boundaries:

Directory Purpose
mozaiksai/ AI runtime — workflow execution, transport, persistence
factory_app/workflows/ Factory layer — builder/generator workflows and agent configs
factory_app/app/ Studio first-party app bundle
chat-ui/ React component library
web_shell/ Local dev frontend shell

Design Principles

  • Structured-output-first — every canonical YAML contract must be representable as a strict typed model
  • Declarative-first runtime — no hardcoded workflow behavior in the runtime
  • No backward-compatibility shims — this repo is pre-production; replace outdated logic cleanly
  • Pre-production cleanup policy — optimize for the cleanest canonical implementation, not legacy preservation
