Openspec

This teaches Claude the OpenSpec artifact-driven workflow, a filesystem-based system for managing technical changes through structured artifacts like proposals, specs, and tasks. You'd reach for it when planning features or refactors that need clear dependency tracking without the overhead of a full project management tool. The OPSX commands (/opsx:new, /opsx:continue, /opsx:apply) walk you through creating artifacts in the right order based on a dependency graph. It's deterministic by design, the CLI won't guess your active change, and schemas live in XDG directories so you can fork and customize the workflow. Honestly more useful for teams that think in artifacts than those happy with linear ticket systems.
