OpenCairn

Session chaining and review skills for Claude Code plus a structured Obsidian vault for planning

Pluginfree

OpenCairn is a productivity system for Claude Code and Obsidian that uses session chaining, structured day/week/quarter review loops, and a dedicated vault so returning to a paused project doesn't mean reconstructing context from scratch. It also ships portable skills that work in any Claude Code project, including a five-layer, optionally cross-model review command for code, configs, or decisions. It is aimed at Claude Code users managing long-running personal work.
