open-prose

Overview

OpenProse is a programming language designed for long-running AI sessions, treating the session itself as a Turing-complete computer and IoC container. It provides a declarative syntax for orchestrating AI agents with control flow constructs like parallel execution, loops with semantic evaluation, and multi-agent workflows that run inside agent sessions on Claude Code, OpenCode, and Amp.

Key Features

• Session as Runtime - Runs inside the agent session rather than orchestrating from outside, with the session serving as both interpreter and runtime
• Fourth Wall Syntax - The **...** syntax enables semantic evaluation where AI judgment replaces strict execution (e.g., loop until the code is production ready)
• Multi-Agent Orchestration - Declare agents with specific models and skills, then compose them with parallel, sequential, and loop control flow
• Zero Lock-in - An open language specification that works on any Prose Complete system (Claude Code + Opus, OpenCode + Opus, Amp + Opus)
• Cross-Platform Installation - Installable via Claude Code plugin marketplace, OpenCode skill directory, or Amp configuration

Who is this for?

OpenProse is for AI power users and developers who want to build complex multi-agent workflows with structured control flow rather than ad-hoc prompting. It is particularly suited for those working with Claude Code, OpenCode, or Amp who need repeatable, composable AI orchestration patterns like research pipelines, iterative refinement loops, and parallel analysis tasks.
