Developer-Tooling

An agent project brain that plans your project, mirrors every piece of work to your real issue tracker, remembers what it learned, and verifies what it shipped — born a Claude Code plugin, now running on Grok, Copilot, Codex, Gemini, Cursor, OpenCode, and Zed too.

Zero to a tracker-mirrored project in about fifteen minutes — install cairn, wire up your issue tracker (including every step that happens outside Claude), and run your first phase.
