OpenProse is a declarative language for standing model work in which you describe desired world states in Markdown contracts and a reconciler handles execution. Rather than scripting sequential agent steps that drift over time, you declare what must stay true and the system determines how much work is needed to keep reality matching that declaration. It ships as a skill for coding agents like Claude Code or Codex CLI with no separate binary or server to run.
- The core unit is a "Responsibility" whose Maintains section defines material fields and a content-hash fingerprint to avoid redundant re-runs
- The dependency graph self-wires: a node's Requires section subscribes to upstream Maintains facets, so structure emerges from the contracts rather than being explicitly drawn
- Five kinds exist: responsibility, function, gateway, pattern, and test
- Continuity (when a node wakes) is a first-class contract section, not an afterthought
- Optional imperative ProseScript plans are available for cases requiring exact choreography

Chrome 135 introduces new capabilities for providing declarative behaviour with the new command and commandfor attributes, enhancing and replacing the popovertargetaction and popovertarget attributes.
The article discusses the evolution of Infrastructure as Code (IaC), transitioning from imperative to declarative approaches, and now back to a hybrid model. This shift is driven by developer experience and the need for scalable, efficient cloud solutions, with modern tools allowing for imperative-style interfaces while maintaining declarative principles.
A simple yet powerful approach to Web Component server-rendering, declarative behaviors, and JavaScript islands using DSD, HTMX, and Islands.
