Documentation
Synthex was built as a Claude Code plugin and is now a shared Agent Skills distribution. Its specialist workflows take software from a messy idea to a peer-reviewed plan to production-ready, parallel-executed code in Claude Code, Codex, Grok, Gemini CLI, OpenCode, and other compatible harnesses. These docs cover installation, the lifecycle, every agent and command, and how to extend the system.
What is Synthex?
Synthex is Claude-first agentic software delivery: specialist agents and commands that take software from a messy idea to a peer-reviewed plan to production-ready, parallel-executed code. Claude Code, Codex, and Grok install it as a plugin; Gemini CLI and OpenCode consume its Agent Skills bundle. The behavioral source is plain Markdown and YAML, distributed through the LumenAI marketplace, and inspectable end-to-end.
Start here
- Getting started — install the plugin and run your first loop in three commands.
- Agent compatibility — choose an install path for Claude Code, Codex, Grok, Gemini CLI, OpenCode, or another Agent Skills host.
Concepts
The full conceptual map (philosophy, lifecycle, quality gates, parallel execution, reviewer pipeline, marketplace) lands in the next docs wave. For now the Getting started guide is the fastest path to a working setup.
Recently published:
- Native looping — iterate any Synthex command (or an arbitrary prompt) until a completion promise fires, with per-session state and cross-session resume.
Reference
Per-agent and per-command reference pages have their own canonical URLs and OG cards:
- Agents — directory of the specialist agents grouped by tier
- Commands — directory of the command workflows grouped by phase
