Open-source declarative programming language for AI sessions where workflows are written as Markdown contracts that run on any AI coding harness.
OpenProse is a language and framework where AI workflows are written as .prose.md files with typed contracts: responsibilities declare what they subscribe to (Requires) and what truth they maintain (Maintains), and functions declare parameters and returns. Forme, the intelligent dependency injector, wires responsibilities by contract matching so agents coordinate without custom configuration files. Sources are harness-agnostic and run on Claude Code, Codex, OpenCode, and Amp without modification. A managed cloud tier runs the same responsibilities on schedule or on events with durable traces, signed receipts, and guarded trigger endpoints; the language and runtime are MIT-licensed. OpenProse is a product of OpenProse.
