# OpenProse > A programming language for the intelligent VM. OpenProse sources are > structured `*.prose.md` Markdown files — responsibilities, services, > systems, contracts, shapes, and strategies — that an LLM reads and executes. > The language is harness-agnostic and runs on any > Prose Complete harness: Claude Code, OpenCode, Codex CLI, Amp, Press. ## Agent Onboarding - [Arrival narrative (markdown)](https://prose.md/llms-full.txt): canonical one-screen onboarding — what OpenProse is, install command, what you'll do when the skill activates, when to decline. Start here. - [Arrival narrative (rendered)](https://prose.md/llms-full): the same content as HTML. - [SKILL.md](https://raw.githubusercontent.com/openprose/prose/v0.8.1/skills/open-prose/SKILL.md): full operational playbook loaded post-activation — recognition signals, proposal script, Host Primitive Adapter, giving-back actions. ## Language Reference - [Prose VM spec](https://raw.githubusercontent.com/openprose/prose/v0.8.1/skills/open-prose/prose.md): declarative `*.prose.md` sources, contracts, shapes, strategies, and two-phase execution. - [Forme framework](https://raw.githubusercontent.com/openprose/prose/v0.8.1/skills/open-prose/forme.md): intelligent DI container that auto-wires Prose components by contract matching. - [Design tenets](https://raw.githubusercontent.com/openprose/prose/v0.8.1/skills/open-prose/guidance/tenets.md): principles the language is optimized for. ## More - [Examples](https://github.com/openprose/prose/tree/v0.8.1/skills/open-prose/examples): 50+ annotated `*.prose.md` sources. - [Docs start](https://docs.prose.md/start/what-is-openprose): the human-facing docs entrypoint. - [Docs start (markdown)](https://docs.prose.md/start/what-is-openprose.mdx): the same docs page as markdown. - [Reference specs](https://docs.prose.md/reference/specs): docs-site entrypoint for the canonical specs. - [Docs agent corpus](https://docs.prose.md/llms.txt): docs-site llms.txt. - [Home page (markdown)](https://prose.md/index.md): product overview in markdown. - [Built on Prose (markdown)](https://prose.md/built-on-prose.md): showcase of responsibilities running in production. ## Talk to us - Email [support@agents.openprose.ai](mailto:support@agents.openprose.ai) for an automated, docs-grounded reply — or from any agent CLI: `npx skills add primitivedotdev/chat`, then `primitive chat support@agents.openprose.ai ""`.
