Cairn

Lean, on-demand development workflow plugin for Claude Code that stays out of the way until needed.

Pluginfreeglobal

Cairn is a free, non-invasive Claude Code plugin that adds just enough workflow structure - a builder-reviewer-PR path for routine changes, an escalated planner path for complex ones - without copying anything permanent into your codebase, so it can be removed without a trace. It's built to be a considerate guest rather than adding overhead to every change.
